Bridge binds message to srcChainId
Cap (cUSD / stcUSD)'s assessment for RD-F-152 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
LayerZero v2 OFT protocol includes source EID in message packets. Ethereum EID = 30101, MegaETH EID = 30398 per layerzero-v2-deployments.json. Messages are bound to (srcEid, dstEid, nonce) tuple in EndpointV2. Per-chain separation enforced by EndpointV2 packet structure at the protocol level.

Methodology #
Determine whether the bridge message struct includes `srcChainId` and the verifier enforces per-chain separation.
