ERC1155 written in pure Yul

List of supported functions (ERC-1155 standard):

• ✅ balanceOf(address account, uint256 id)
• ✅ balanceOfBatch(address[] calldata accounts, uint256[] calldata ids)
• ✅ setApprovalForAll(address _operator, bool _approved)
• ✅ isApprovedForAll(address _owner, address _operator)
• ✅ safeTransferFrom(address _from, address _to, uint256 _id, uint256 _value, bytes calldata _data)
• ✅ safeBatchTransferFrom(address _from, address _to, uint256[] calldata _ids, uint256[] calldata _values, bytes calldata _data)
• ✅ uri(uint256 _id)
• ✅ setURI(address _from, address _to, uint256[] calldata _ids, uint256[] calldata _values, bytes calldata _data)

List of non-standard functions:

• ✅ mint(address to, uint256 id, uint256 amount, bytes calldata data)
• ✅ batchMint(address to, uint256 id, uint256 amount, bytes calldata data)

List of events:

• ✅ event TransferBatch( address indexed operator, address indexed from, address indexed to, uint256[] ids, uint256[] values );
• ✅ event TransferSingle( address indexed operator, address indexed from, address indexed to, uint256 id, uint256 value );
• ✅ event ApprovalForAll( address indexed account, address indexed operator, bool approved );

Repository installation

1. Install Foundry

curl -L https://foundry.paradigm.xyz | bash
foundryup

• Install solidity compiler https://docs.soliditylang.org/en/latest/installing-solidity.html#installing-the-solidity-compiler

• Build Yul contracts and check tests pass

forge test

Running tests

Run tests (compiles yul then fetch resulting bytecode in test)

forge test

To see the console logs during tests

forge test -vvv
