Bridge
Infrastructure
System to transfer assets or messages across chains.
Bridges move tokens or messages between chains via custodial, light client, or validator-based designs. They introduce additional trust and security assumptions; audits and operational maturity are critical.
Frequently asked questions
How do token bridges typically work?
They lock tokens on the source chain and mint representations on the destination, or use message passing with light clients/validators to release escrowed funds.What are the main risks?
Smart‑contract bugs, validator key compromises, or incorrect message verification. Prefer canonical/system bridges when possible and verify custody models.Why are withdrawals sometimes delayed?
Security windows, finality requirements, or challenge periods (optimistic designs) can introduce delays before funds are released.
