AAVE StETH Integration Deployment

The repository contains scripts for deployment and verification of the implementation of the StETH integration on AAVE.

Project Setup

To use the tools provided by this project, please pull the repository from GitHub and install its dependencies as follows. It is recommended to use a Python virtual environment.

git clone https://github.com/lidofinance/aave-asteth-deployment
cd aave-asteth-deployment
python3 -m venv .venv
source .venv/bin/activate
pip3 install -r requirements-dev.txt

To run scripts and tests in this repo, store your project ID as an environment variable named WEB3_INFURA_PROJECT_ID. You can do so with the following command:

$ export WEB3_INFURA_PROJECT_ID=YourProjectID

Note that for correct work of scripts you have to have exact the "1.17.0" version of the eth-brownie package.

Deployment

To run deployment use the command DEPLOYER=<DEPLOYER_ACCOUNT> brownie run deploy. This command will deploy contracts required for StETH listing on AAVE:

• AStETH.sol (SHA-256 hash: 0x7e86a48c1d4b43a5e4ebca7d44704a6ef273a93ba049e9c1cd19cb512da12b98)
• VariableDebtStETH.sol (SHA-256 hash: 0xa6461b9f089d5a8f64edef1d37523ddb11e2973f1ea2f2996961f61e83c5a969)
• StableDebtStETH.sol (SHA-256 hash: 0x7e86a48c1d4b43a5e4ebca7d44704a6ef273a93ba049e9c1cd19cb512da12b98)
• DefaultReserveInterestRateStrategy.sol (SHA-256 hash: 0x52e45a1e4d0969524a362cabb4370176303b62d511ba2321e95d37c49287fdab)

Bytecode Checking

To validate that bytecode of contracts deployed in the mainnet network matches the bytecode of contracts deployed via scripts from this repo, you can use the command brownie run check_bytecode. This command will do the next steps to validate the bytecode of the deployed contracts:

1. Download bytecode of contracts deployed in the mainnet via JSON-RPC call to Ethereum node.
2. Deploy contracts in the mainnet fork via scripts in this repo.
3. Download bytecode of newly deployed contracts from the mainnet fork via JSON-RPC call.
4. Compare that bytecode of previously and newly deployed contracts match except ipfs hash in metadata section.

Tests

To run the acceptance test use the command brownie test -s.
