How do I bridge tokens to a different network?

Layer 1 networks refer to a base blockchain protocol. Examples of layer 1 networks are Bitcoin, BNB chain, Avalanche, and Ethereum.


Layer 2 networks refer to a separate network built on top of the Layer 1 networks. Examples of Layer 2 networks are Optimism, Arbitrum, Celo, and Polygon.


The Uniswap v2 and v3 Protocols are both currently available on the following networks - Ethereum, BNB chain, Optimism, Arbitrum, Polygon, Celo, Base, Blast, and Avalanche.


To move assets from the one network to another network, you’ll need to connect your wallet to a bridge and deposit funds.


There are many bridges, here are a few options you can use: Optimism Bridge, Polygon Bridge, Arbitrum bridge, Celo bridge, BNB bridge, Base Bridge, Blast Bridge, ZKsync bridge, and Avalanche bridge.


For information on how to bridge tokens on different networks, please see the following:
