Subject: [PATCH 01/18] fix(contracts-rfq): FastBridge V2 prove race condition
 (#3435)

* feat: scaffold new prover management

* test: define unit tests for prover management

* feat: implement prover management

* feat: deprecate prover role constant

* test: update to constant deprecation

* feat: additional prover getters

* feat: prover timeout management

* test: coverage for timeout management

* test: should save proverID for origin txs

* feat: save proverID, pack BridgeTxDetails

* test: define expected behavior for prover timeouts

* feat: implement timeout penalty in dispute

* fix: Role Admin should be handling provers, as before

* refactor: "prover timeout" -> "dispute penalty time"

+
+We are excited to announce the **Synapse Intent Network**.
+
+<!--truncate-->
+
+# Summary
+
+The Synapse Intent Network is a cross-chain communication protocol that enables seamless asset transfers and message passing between different blockchain networks. At its core, it provides a robust infrastructure for executing complex cross-chain operations while maintaining security and efficiency.
+
+<figure>
+	<RFQFlow />
+	<figcaption>RFQ flow: get Quote, get txData, sign transaction</figcaption>
+</figure>
+
+<br/>
+
+This major protocol upgrade represents a fundamental shift in the architecture, introducing intent-based routing, advanced bridging capabilities, and significant gas optimizations. The changes reflect a deeper focus on user experience while substantially improving the protocol's security, efficiency, and scalability.
+## Key Improvements At-A-Glance
+
+* **Gas Optimization Revolution**
+  * Achieved 30-50% reduction in transaction costs through storage and execution improvements
+  * Built-In Multicall allows efficient batching to save 21,000+ gas per operation
+
+* **Powerful Intent-Based Routing**
+  * New "Zap" architecture enables complex actions to be atomically executed after the intent is fulfilled
+  * Reduces cross-contract calls
+  * Allows for sophisticated bridging scenarios
+
+* **Exclusive Relayer Functionality**
+  * Intents can be assigned for exclusive fulfillment only by the Relayer who provided the best quote.
+  * This eliminates wasteful on-chain competition while still incentivizing low fees and fast fills.
+

+  * Multiple Quoting options for relayers to choose from to maximize competitiveness
+
+## Synapse Intent Network: Technical Improvements
+
+### Quoting and API Improvements
+
+The transition to the Synapse Intent Network brings significant changes to our quoting infrastructure, focusing on real-time price discovery and efficient market making. The most notable addition is active quoting alongside our existing passive quoting system.
+
+#### Active Quoting
+
+Traditional passive quoting works like an order book - relayers post standing offers that users can take. While this model is simple and efficient for stable market conditions, it can lag during volatile periods. Active quoting addresses this limitation by enabling relayers to respond to quote requests in real-time:
+
+```typescript
+// Example WebSocket quote request format
+interface QuoteRequest {
+  data: {
+    origin_chain_id: number;
+    dest_chain_id: number;
+    origin_token_addr: string;
+    dest_token_addr: string;
+    origin_amount_exact: string;
+    expiration_window: number;
+  }
+}
+```
+
+This hybrid approach gives relayers flexibility in their market-making strategies. Simple integrations can stick with passive quoting, while sophisticated relayers can implement dynamic pricing models that account for immediate market conditions, liquidity depth, and cross-chain gas costs.
+
+### WebSocket API Evolution
+
+Supporting this new quoting model required rethinking our API infrastructure. The new WebSocket layer eliminates the need for polling and complex state management:
+
+```typescript
+const operations = {
+  subscribe: "Subscribe to specific chains",
+  send_quote: "Respond to quote request",
+  request_quote: "New quote request notification"
+}
+```
+
+The real-time nature of WebSockets dramatically reduces quote latency. Rather than repeatedly querying for updates, relayers receive instant notifications about new opportunities. This improved efficiency translates directly to better pricing for end users as relayers can operate with tighter spreads.
+
+## Contract Improvements
+
+:::info
+
+The Synapse Intent Network is backwards combatible with the original Fastbridge Contracts.
+
+:::
+
+### Gas Optimizations
+
+A core focus of V2 was reducing transaction costs without sacrificing code clarity. Through careful struct packing and custom error implementations, we've achieved significant gas savings:
+
+```solidity
+struct BridgeTxDetails {
+    BridgeStatus status;           // 1 byte
+    uint32 destChainId;           // 4 bytes
+    uint16 proverID;              // 2 bytes
+    uint40 proofBlockTimestamp;   // 5 bytes
+    address proofRelayer;         // 20 bytes
+} // Total: 32 bytes (1 slot)
+```
+
+These optimizations balance efficiency with maintainability. While more aggressive packing was possible, it would have made the code significantly harder to reason about. The current implementation provides meaningful gas savings while keeping the codebase approachable for new developers.
+
+### Atomic Operations with Multicall and Zaps
+
+Cross-chain operations often require multiple transactions. V2 introduces multicall support and a new Zap interface to address this friction:
+
+```solidity
+// Multicall enables efficient batching
+fastBridge.multicallNoResults([
+    abi.encodeCall(IFastBridge.prove, (request1)),
+    abi.encodeCall(IFastBridge.claim, (request1))
+], false);
+
+// Zaps enable complex atomic operations
+interface IZapRecipient {
+    function zap(
+        address token,
+        uint256 amount,
+        bytes memory zapData
+    ) external payable returns (bytes4);
+}
+```
+
+The Zap interface is intentionally minimal, maximizing composability while maintaining security. It enables powerful workflows like "bridge and stake" or "bridge and provide liquidity" in a single atomic transaction. These compound operations significantly improve the user experience by reducing transaction overhead and eliminating partial execution risks.
+
+## Final Thoughts
+
+The Synapse Intent Network (FastBridgeV2) update represents a thoughtful evolution of our protocol. Each change was evaluated not just for its immediate benefits, but for its long-term impact on protocol composability and user experience. The result is a more efficient, developer-friendly, and user-centric cross-chain bridging system. Please reach out to us if you have any questions or feedback.

Subject: [PATCH 14/18] feat: add golangci-lint version manager (#3457)

The changes in this pull request involve updates to the Go workflow configuration, the introduction of a new Golang CI Lint Version Manager, and enhancements to documentation files. The workflow modifications include dynamic version handling for golangci-lint and improved job execution conditions. Additionally, the .golangci-version file has been updated to specify a new version. Documentation in CONTRIBUTING.md, README.md, and a new README.md for the Golang CI Lint Version Manager has been added to clarify contribution processes and setup instructions.

 ## Linting
 
-Linting for go is used using [golangci-lint](https://golangci-lint.run/) at the latest released version. Please upgrade or install using your package manager. and run `make lint` from your desired module.
+Linting for Go code uses [golangci-lint](https://golangci-lint.run/). The version is pinned in `.golangci-version` file and managed automatically through our tooling. Simply run `make lint` from your desired module, and the correct version will be downloaded (if not already cached) and used automatically.
+
+### Golang-CI-Lint Module
+The `contrib/golang-ci-lint` module provides version-pinned golangci-lint execution across repositories. The module automatically downloads and manages the correct version of golangci-lint based on the version specified in `.golangci-version` file, ensuring consistent linting across all Go modules.
+
+#### Building and Testing
+```bash
+cd contrib/golang-ci-lint
+make lint
+make test
+```
+
+For more details about the module's implementation and usage, see the [module's README](contrib/golang-ci-lint/README.md).

+### Go Development Setup
+
+For Go development:
+1. The project uses a specific version of golangci-lint that is managed automatically through our version management system
+2. No manual installation of golangci-lint is required
+3. The version is pinned in `.golangci-version` file and managed by the `contrib/golang-ci-lint` module

+### Golang-CI-Lint Version Management
+The repository uses a pinned version of golangci-lint specified in `.golangci-version`. The linter is automatically downloaded and executed through `make lint`. This ensures consistent linting across all Go modules and development environments.
+
+Key features:
+- Automatic version management based on `.golangci-version`
+- Cross-platform compatibility
+- Secure download and verification
+- Caching for improved performance

+# Golang CI Lint Version Manager
+
+A standalone tool for managing and running specific versions of golangci-lint across different repositories. This package can be used in any Go project to ensure consistent linting with version pinning, regardless of where it's installed.
+
+## Features
+- **Cross-Repository Usage**: Can be installed and used in any Go project
+- **Version Pinning**: Automatically uses the version specified in `.golangci-version`
+- **Architecture Support**: Downloads correct binary for your system (AMD64/ARM64)
+- **Binary Caching**: Avoids redundant downloads of the same version
+- **Secure Downloads**: Verifies binary checksums for security
+- **CI/CD Integration**: Easy to integrate with GitHub Actions and other CI systems
+
+## Installation
+
+As a standalone tool:
+```bash
+go install github.com/synapsecns/sanguine/contrib/golang-ci-lint@latest
+```
+
+Or in your project's go.mod:
+```go
+require github.com/synapsecns/sanguine/contrib/golang-ci-lint v1.0.0
+```
+
+## Usage
+
+### 1. Version Configuration
+Create a `.golangci-version` file in your repository root:
+```
+1.61.0
+```
+
+### 2. Running the Linter
+
+As a standalone binary:
+```bash
+golang-ci-lint run --fix --config=.golangci.yml
+```
+
+Or using go run:
+```bash
+go run github.com/synapsecns/sanguine/contrib/golang-ci-lint run --fix --config=.golangci.yml
+```
+
+### 3. Makefile Integration
+
+Add to your project's Makefile:
+```makefile
+.PHONY: lint
+lint:
+	go run github.com/synapsecns/sanguine/contrib/golang-ci-lint run --fix --config=.golangci.yml
+```
+
+### 4. CI/CD Integration
+
+GitHub Actions example:
+```yaml
+name: Lint
+on: [push, pull_request]
+
+jobs:
+  golangci:
+    name: lint
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-go@v4
+        with:
+          go-version: '1.21'
+      - name: Install golang-ci-lint manager
+        run: go install github.com/synapsecns/sanguine/contrib/golang-ci-lint@latest
+      - name: Run linter
+        run: golang-ci-lint run --config=.golangci.yml
+```
+
+## Common Use Cases
+
+1. **Multiple Projects**: Use the same linter version across all your repositories
+2. **CI/CD Pipelines**: Ensure consistent linting in automated workflows
+3. **Team Collaboration**: Maintain consistent code style across development teams
+4. **Version Control**: Lock linter version to avoid unexpected behavior changes
+
+## Troubleshooting
+
+1. **Binary Not Found**
+   ```bash
+   # Clear the cache and redownload
+   rm -rf ~/.cache/golangci-lint
+   golang-ci-lint run
+   ```
+
+2. **Version Mismatch**
+   - Ensure `.golangci-version` exists in repository root
+   - Check file permissions and format
+
+3. **Architecture Issues**
+   - The tool automatically detects and downloads the correct binary
+   - Supported architectures: linux-amd64, linux-arm64, darwin-amd64, darwin-arm64, windows-amd64
+   - MacOS (/private/var) symlink handling:
+     - Properly resolves /private/var to /var for temp directories
+     - Maintains secure path validation across symlinked paths
+     - Handles platform-specific temp directory structures
+
+## Contributing
+
+Contributions are welcome! Please ensure:
+- Cross-platform compatibility:
+  - Linux: Standard path resolution
+  - MacOS: Handles /private/var symlinks and temp directories
+  - Windows: Supports standard Windows paths
+- Backward compatibility with existing `.golangci-version` files
+- Proper error handling and user feedback

+// Package main provides a tool for downloading and running specific versions of golangci-lint
+// across different architectures and repositories. It supports version pinning through
+// .golangci-version files and maintains a local cache of downloaded binaries.
+//
+// Security Features:
+//   - Validates all file paths and URLs
+//   - Enforces secure file permissions (0400 for files, 0750 for directories)
+//   - Prevents command injection
+//   - Implements secure archive extraction
+//   - Uses cryptographic verification for downloads
+//   - Handles decompression bombs (50MB limit)
+//   - Validates binary paths and permissions
+//
+// Usage:
+//
+//	golang-ci-lint [flags] [golangci-lint arguments]
+//
+// The tool automatically:
+//   - Downloads the correct version for the current architecture
+//   - Caches binaries for future use
+//   - Validates security constraints
+//   - Propagates exit codes from golangci-lint
+//   - Supports cross-repository usage via go-findroot
+//
+// Environment:
+//   - Uses go-findroot for repository detection
+//   - Maintains secure file permissions
+//   - Supports various architectures and operating systems
+//   - Handles timeouts and cancellation via context
+//
+// Example:
+//
+//	golang-ci-lint run --fix --config=/path/to/.golangci.yml
+//
+// Note: This tool is designed to be used across different repositories and
+// automatically detects the repository root using go-findroot.

By not relying on {IERC20-approve}, the token holder account doesn't\n * need to send a transaction, and thus is not required to hold Ether at all.\n *\n * ==== Security Considerations\n *\n * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

By not relying on {IERC20-approve}, the token holder account doesn't\n * need to send a transaction, and thus is not required to hold Ether at all.\n *\n * ==== Security Considerations\n *\n * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

Some\n * applications may benefit from on-chain enumerability, for those cases see\n * {AccessControlEnumerable}.\n *\n * Roles are referred to by their `bytes32` identifier. These should be exposed\n * in the external API and be unique. The best way to achieve this is by\n * using `public constant` hash digests:\n *\n * ```solidity\n * bytes32 public constant MY_ROLE = keccak256(\"MY_ROLE\");\n * ```\n *\n * Roles can be used to represent a set of permissions. To restrict access to a\n * function call, use {hasRole}:\n *\n * ```solidity\n * function foo() public {\n *     require(hasRole(MY_ROLE, msg.sender));\n *     ...\n * }\n * ```\n *\n * Roles can be granted and revoked dynamically via the {grantRole} and\n * {revokeRole} functions. Each role has an associated admin role, and only\n * accounts that have a role's admin role can call {grantRole} and {revokeRole}.\n *\n * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means\n * that only accounts with this role will be able to grant or revoke other\n * roles. More complex role relationships can be created by using\n * {_setRoleAdmin}.\n *\n * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to\n * grant and revoke this role. Extra precautions should be taken to secure\n * accounts that have been granted it. We recommend using {AccessControlDefaultAdminRules}\n * to enforce additional security measures for this role.\n */\nabstract contract AccessControl is Context, IAccessControl, ERC165 {\n    struct RoleData {\n        mapping(address account =\u003e bool) hasRole;\n        bytes32 adminRole;\n    }\n\n    mapping(bytes32 role =\u003e RoleData) private _roles;\n\n    bytes32 public constant DEFAULT_ADMIN_ROLE = 0x00;\n\n    /**\n     * @dev Modifier that checks that an account has a specific role.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

Some\n * applications may benefit from on-chain enumerability, for those cases see\n * {AccessControlEnumerable}.\n *\n * Roles are referred to by their `bytes32` identifier. These should be exposed\n * in the external API and be unique. The best way to achieve this is by\n * using `public constant` hash digests:\n *\n * ```solidity\n * bytes32 public constant MY_ROLE = keccak256(\"MY_ROLE\");\n * ```\n *\n * Roles can be used to represent a set of permissions. To restrict access to a\n * function call, use {hasRole}:\n *\n * ```solidity\n * function foo() public {\n *     require(hasRole(MY_ROLE, msg.sender));\n *     ...\n * }\n * ```\n *\n * Roles can be granted and revoked dynamically via the {grantRole} and\n * {revokeRole} functions. Each role has an associated admin role, and only\n * accounts that have a role's admin role can call {grantRole} and {revokeRole}.\n *\n * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means\n * that only accounts with this role will be able to grant or revoke other\n * roles. More complex role relationships can be created by using\n * {_setRoleAdmin}.\n *\n * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to\n * grant and revoke this role. Extra precautions should be taken to secure\n * accounts that have been granted it. We recommend using {AccessControlDefaultAdminRules}\n * to enforce additional security measures for this role.\n */\nabstract contract AccessControl is Context, IAccessControl, ERC165 {\n    struct RoleData {\n        mapping(address account =\u003e bool) hasRole;\n        bytes32 adminRole;\n    }\n\n    mapping(bytes32 role =\u003e RoleData) private _roles;\n\n    bytes32 public constant DEFAULT_ADMIN_ROLE = 0x00;\n\n    /**\n     * @dev Modifier that checks that an account has a specific role.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

Some\n * applications may benefit from on-chain enumerability, for those cases see\n * {AccessControlEnumerable}.\n *\n * Roles are referred to by their `bytes32` identifier. These should be exposed\n * in the external API and be unique. The best way to achieve this is by\n * using `public constant` hash digests:\n *\n * ```solidity\n * bytes32 public constant MY_ROLE = keccak256(\"MY_ROLE\");\n * ```\n *\n * Roles can be used to represent a set of permissions. To restrict access to a\n * function call, use {hasRole}:\n *\n * ```solidity\n * function foo() public {\n *     require(hasRole(MY_ROLE, msg.sender));\n *     ...\n * }\n * ```\n *\n * Roles can be granted and revoked dynamically via the {grantRole} and\n * {revokeRole} functions. Each role has an associated admin role, and only\n * accounts that have a role's admin role can call {grantRole} and {revokeRole}.\n *\n * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means\n * that only accounts with this role will be able to grant or revoke other\n * roles. More complex role relationships can be created by using\n * {_setRoleAdmin}.\n *\n * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to\n * grant and revoke this role. Extra precautions should be taken to secure\n * accounts that have been granted it. We recommend using {AccessControlDefaultAdminRules}\n * to enforce additional security measures for this role.\n */\nabstract contract AccessControl is Context, IAccessControl, ERC165 {\n    struct RoleData {\n        mapping(address account =\u003e bool) hasRole;\n        bytes32 adminRole;\n    }\n\n    mapping(bytes32 role =\u003e RoleData) private _roles;\n\n    bytes32 public constant DEFAULT_ADMIN_ROLE = 0x00;\n\n    /**\n     * @dev Modifier that checks that an account has a specific role.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

By not relying on {IERC20-approve}, the token holder account doesn't\n * need to send a transaction, and thus is not required to hold Ether at all.\n *\n * ==== Security Considerations\n *\n * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

Some\n * applications may benefit from on-chain enumerability, for those cases see\n * {AccessControlEnumerable}.\n *\n * Roles are referred to by their `bytes32` identifier. These should be exposed\n * in the external API and be unique. The best way to achieve this is by\n * using `public constant` hash digests:\n *\n * ```solidity\n * bytes32 public constant MY_ROLE = keccak256(\"MY_ROLE\");\n * ```\n *\n * Roles can be used to represent a set of permissions. To restrict access to a\n * function call, use {hasRole}:\n *\n * ```solidity\n * function foo() public {\n *     require(hasRole(MY_ROLE, msg.sender));\n *     ...\n * }\n * ```\n *\n * Roles can be granted and revoked dynamically via the {grantRole} and\n * {revokeRole} functions. Each role has an associated admin role, and only\n * accounts that have a role's admin role can call {grantRole} and {revokeRole}.\n *\n * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means\n * that only accounts with this role will be able to grant or revoke other\n * roles. More complex role relationships can be created by using\n * {_setRoleAdmin}.\n *\n * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to\n * grant and revoke this role. Extra precautions should be taken to secure\n * accounts that have been granted it. We recommend using {AccessControlDefaultAdminRules}\n * to enforce additional security measures for this role.\n */\nabstract contract AccessControl is Context, IAccessControl, ERC165 {\n    struct RoleData {\n        mapping(address account =\u003e bool) hasRole;\n        bytes32 adminRole;\n    }\n\n    mapping(bytes32 role =\u003e RoleData) private _roles;\n\n    bytes32 public constant DEFAULT_ADMIN_ROLE = 0x00;\n\n    /**\n     * @dev Modifier that checks that an account has a specific role.

By not relying on {IERC20-approve}, the token holder account doesn't\n * need to send a transaction, and thus is not required to hold Ether at all.\n *\n * ==== Security Considerations\n *\n * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

module that allows children to implement role-based access control mechanisms. This is a lightweight version that doesn't allow enumerating role members except through off-chain means by accessing the contract event logs. Some applications may benefit from on-chain enumerability, for those cases see {AccessControlEnumerable}. Roles are referred to by their `bytes32` identifier. These should be exposed in the external API and be unique. The best way to achieve this is by using `public constant` hash digests: ```solidity bytes32 public constant MY_ROLE = keccak256(\"MY_ROLE\"); ``` Roles can be used to represent a set of permissions. To restrict access to a function call, use {hasRole}: ```solidity function foo() public {     require(hasRole(MY_ROLE, msg.sender));     ... } ``` Roles can be granted and revoked dynamically via the {grantRole} and {revokeRole} functions. Each role has an associated admin role, and only accounts that have a role's admin role can call {grantRole} and {revokeRole}. By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means that only accounts with this role will be able to grant or revoke other roles. More complex role relationships can be created by using {_setRoleAdmin}. WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to grant and revoke this role.

This is a lightweight version that doesn't allow enumerating role members except through off-chain means by accessing the contract event logs. Some applications may benefit from on-chain enumerability, for those cases see {AccessControlEnumerable}. Roles are referred to by their `bytes32` identifier. These should be exposed in the external API and be unique. The best way to achieve this is by using `public constant` hash digests: ```solidity bytes32 public constant MY_ROLE = keccak256(\\\"MY_ROLE\\\"); ``` Roles can be used to represent a set of permissions. To restrict access to a function call, use {hasRole}: ```solidity function foo() public {     require(hasRole(MY_ROLE, msg.sender));     ... } ``` Roles can be granted and revoked dynamically via the {grantRole} and {revokeRole} functions. Each role has an associated admin role, and only accounts that have a role's admin role can call {grantRole} and {revokeRole}. By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means that only accounts with this role will be able to grant or revoke other roles. More complex role relationships can be created by using {_setRoleAdmin}. WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to grant and revoke this role.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

By not relying on {IERC20-approve}, the token holder account doesn't\n * need to send a transaction, and thus is not required to hold Ether at all.\n *\n * ==== Security Considerations\n *\n * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun.

The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.

The first is that a valid permit signature\n * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be\n * considered as an intention to spend the allowance in any specific way. The second is that because permits have\n * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should\n * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be\n * generally recommended is:\n *\n * ```solidity\n * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {\n *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}\n *     doThing(..., value);\n * }\n *\n * function doThing(..., uint256 value) public {\n *     token.safeTransferFrom(msg.sender, address(this), value);\n *     ...\n * }\n * ```\n *\n * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of\n * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n    /**\n     * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n     * given ``owner``'s signed approval.\n     *\n     * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n     * ordering also apply here.\n     *\n     * Emits an {Approval} event.\n     *\n     * Requirements:\n     *\n     * - `spender` cannot be the zero address.\n     * - `deadline` must be a timestamp in the future.\n     * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n     * over the EIP712-formatted function arguments.\n     * - the signature must use ``owner``'s current nonce (see {nonces}).\n     *\n     * For more information on the signature format, see the\n     * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n     * section].\n     *\n     * CAUTION: See Security Considerations above.\n     */\n    function permit(\n        address owner,\n        address spender,\n        uint256 value,\n        uint256 deadline,\n        uint8 v,\n        bytes32 r,\n        bytes32 s\n    ) external;\n\n    /**\n     * @dev Returns the current nonce for `owner`.
