EIP-712 domain separator missing chainId

Hyperliquid's assessment for RD-F-020 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Bridge2/Signature.sol uses EIP-712 style message construction. Commit 97225667 'Fix 3.4 Signatures may be reused across different contracts' directly addresses cross-contract replay prevention, implying some form of contract-binding in the domain separator. Full domain separator construction (including chainId presence) not fully extractable from available sources without direct code diff of that commit.

Sources #

Methodology #

Determine whether the EIP-712 domain separator struct omits the `chainId` field, allowing cross-chain replay.
