Bridge tracks nonce-consumed mapping
Curve Finance's assessment for RD-F-153 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
LayerZero V2 uses ordered nonce model per pathway (srcEid, sender, dstEid). Endpoint tracks lazyInboundNonce and inboundNonce ensuring ordered delivery and replay protection. Out-of-order messages are queued, not replayed. Each packet is consumed exactly once. Replay protection is structural in LZ V2 endpoint design.
