EIP-712 domain separator missing chainId

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

Evidence summary #

EIP-712 is an Ethereum structured-data signing standard. Babylon does not use EIP-712 anywhere. Bitcoin-side signing uses Taproot (BIP-341). Genesis chain uses Cosmos SDK SIGN_MODE_DIRECT which includes chain-ID (bbn-1) in the SignDoc by construction. Structurally inapplicable.

Methodology #

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