Bridge Security Cluster

Cross-Chain Trust, Message Safety, and Bridge Recovery Controls

This cluster covers how bridge systems fail when message semantics, verifier assumptions, route controls, and reopen logic are weak. Use it to move from broad bridge trust questions into the supporting pages that define validation, containment, and recovery discipline.

Cross-Chain Message Validation Security

Start here for the broadest explanation of how bridges accept, reject, and mis-handle cross-chain messages, then move into replay boundaries, schema design, route controls, and verifier assumptions.

Bridge risk rarely lives alone. Governance and protocol controls shape bridge upgrade power, while wallet and operational controls shape the human paths that actually hold keys, respond to incidents, and recover trust.
