Bridge binds message to srcChainId

Synapse Protocol's assessment for RD-F-152 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

RFQ FastBridge: explicit srcChainId/destChainId binding confirmed (block.chainid). Legacy SynapseBridge: kappa binding partially confirmed — full chain-specificity depends on off-chain validator implementation, not verifiable from contract source alone.

Methodology #

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