Bridge binds message to srcChainId

mETH Protocol'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 Endpoint V2 includes EID (endpoint/chain ID) in the packet Origin struct: srcEid field binds each message to its source chain. Peer validation via setPeer() further enforces which source addresses are valid per EID. Chain separation is enforced at the protocol layer.

Methodology #

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