Bridge tracks nonce-consumed mapping
Ethena'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 tracks nonces at the endpoint level to prevent replay attacks. The lzReceive path enforces ordered message delivery with nonce tracking in the LayerZero endpoint contract (Ethereum: 0x66a71dcef29a0ffbdbe3c6a460a3b5bc225cd675). Ethena's OFT adapter relies on this protocol-level nonce protection. No custom nonce handling in Ethena's own contracts is required given LayerZero's built-in protection.
