A blockchain bridge is a tool that connects two different blockchains so assets or data can move between them — for example, using a token from one network on another. This guide explains how bridges work and what to watch out for.
Why bridges exist
Different blockchains normally can't talk to each other directly. A bridge solves this by linking two networks, letting you move value across them [1]. The most common method locks your asset on the first chain and mints an equivalent "wrapped" token on the second; to move back, the wrapped token is burned and the original is unlocked [2].
How a bridge works
The bottom line
A bridge is the connection that lets assets and information cross between blockchains, making the wider ecosystem more interoperable. It's powerful, but it adds risk: bridges hold locked funds and have been frequent targets for hacks, so use well-established ones and understand the mechanism first.
