Bridging Assets
Moving between layers.
Why Bridges Are Needed
Each L2 (and each chain) has its own state. To use assets across them you need a bridge that moves value between layers.
Bridges let you take ETH on Ethereum and use it on Arbitrum, Optimism, or other networks.
What a Bridge Does
A bridge coordinates two chains so that locking or burning an asset on one side results in receiving it on the other.
The total supply is preserved — assets are not duplicated, just represented on the destination chain.
