Cross-chain messaging vs. asset bridging
Why moving information and moving assets require different trust assumptions.
Cross-chain messaging transports verifiable information between execution environments.
Cross-chain messaging transports verifiable information between execution environments. Asset bridging additionally changes custody, issuance, or accounting state. Both depend on a clear finality model, replay protection, message ordering, and explicit failure handling. A bridge can expose users to liquidity and custody risks even when its message transport is correct. Engineers should document which chain state is authoritative, who can attest to it, and how the receiving system responds to reorganizations or delayed delivery.
