Bridge tracks nonce-consumed mapping
Jito'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 #
Wormhole uses (emitter_chain, emitter_address, sequence) tuple uniqueness and VAA digest-based replay protection. Sequence is auto-incrementing per emitter. Digest (double-keccak256 of VAA body) can be checked against consumed set. Wormhole EVM core contract implements this replay prevention.

Methodology #
Determine whether the bridge inbox maintains a nonce-consumed mapping and rejects replay of used nonces.
