EIP-712 domain separator missing chainId

EigenLayer'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 #

EigenLayer uses EIP-712 structured signing via the standard OpenZeppelin EIP712 implementation, which includes chainId in the domain separator by default. No published audit finding identifies a missing chainId or domain-separator vulnerability. The Code4rena 2023 EigenLayer audit (https://code4rena.com/reports/2023-04-eigenlayer) contains no signature-replay or chainId-related findings — its scope was EigenPod / BeaconChainProofs withdrawal mechanics (H-01, H-02) and strategy/slashing logic. Replay protection for delegation signatures relies on per-staker nonces in DelegationManager.

Methodology #

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