A crypto bridge connects two blockchain networks. It can let users move assets, create wrapped tokens, or transfer value between ecosystems that normally do not talk to each other directly.

How bridges usually work

Many bridges lock an asset on one chain and issue a matching token on another chain. When the user returns, the wrapped token is burned or redeemed and the original asset is released.

Bridge risks

Bridges can be complex and have been frequent targets for attacks. Users should check the network, address, fee, bridge reputation, and token type before sending funds.

Bridges are important because crypto is fragmented across chains such as Ethereum, Solana, Avalanche, and Polygon.
