Cross-Chain Bridge Security Checklist (2026)

A field-tested checklist for auditing cross-chain messaging integrations — where crypto's largest hacks happened.

WHAT'S INSIDE

• 7 categories: message authentication, replay protection, finality/reorg safety, mint-burn invariants, ordering/delivery, config & trust assumptions, app-level receipt logic

• Copy-paste Foundry tests (untrusted source, replay, supply invariant)

• Known-exploit reference map (Nomad/Wormhole-class patterns)

WHO IT'S FOR: auditors & engineers working on bridges and LayerZero/CCIP/Hyperlane/ISMP integrations.
