Infrastructure that enables moving assets or messages across blockchains.
A bridge enables users to move assets or data between blockchains. Common approaches include lock-and-mint (custodial or multi-sig), light-client verification, and message-passing for contract calls.
Lock native coins on Chain A and mint wrapped representations on Chain B (e.g., wBTC on Ethereum). Redeeming burns the wrapped token and releases the original asset.
Bridges are frequent targets for exploits (key compromises, contract bugs). Prefer audited, widely used bridges and test small amounts first.
