Bridge tracks nonce-consumed mapping
mETH Protocol'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 Endpoint V2 tracks message nonces per pathway (srcEid, sender, nonce) with monotonically increasing nonce enforcement. Replayed nonces are rejected at the Endpoint V2 layer. This is a protocol-level guarantee inherited by all OFT adapters using the standard LayerZero V2 stack.
