An introduction to blockchain bridges, interoperability and cross-network asset movement.
A blockchain bridge is infrastructure that helps users or applications move assets or information between separate blockchain environments. Asset bridges commonly coordinate deposits on one network with delivery or representation on another.
Different bridge designs use different trust and security assumptions. Some rely on smart contracts and external validation, while others use liquidity or messaging systems with their own mechanisms.
For users, the practical questions are simpler: does the bridge support the networks and asset, what will I receive, what will it cost, and what transactions must I sign?
Never assume that two networks are interchangeable because they share a token ticker. Verify the destination asset and network using the route details before confirming a transaction.
