EIP-712 domain separator missing chainId
Lista DAO's assessment for RD-F-020 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
hay.sol initializes with chainId_ parameter in initialize(uint256 chainId_, string memory symbol_, uint256 supplyCap_). LisUSD.sol uses OZ upgradeable EIP-712 pattern with chainId in domain separator. Both stablecoin contracts correctly include chainId in domain separator.
