EIP-712 domain separator missing chainId
PancakeSwap's assessment for RD-F-020 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
CAKE token ERC-20 permit uses EIP-712. Exact domain separator struct not inspected from BscScan — static read of contract source was not performed for the CAKE token's DOMAIN_SEPARATOR. PancakeSwap operates cross-chain with the same CAKE token, making chainId presence critical. Cannot grade without source inspection. Marked gray due to insufficient evidence.
Sources #
- Etherscan
Methodology #
Determine whether the EIP-712 domain separator struct omits the `chainId` field, allowing cross-chain replay.
