The Uniswap protocol supports the Ethereum, Polygon, Optimism, Arbitrum, Celo, BNB Chain, Base and Avalanche Networks.
In order to make a swap or add liquidity to tokens on a different network, you must change the network first.
To switch networks:
- Open Uniswap web app and connect your wallet. Next, select the network drop-down in the upper right hand of the screen.
- Select the network you would like to use. Your wallet may be prompted to accept the change.
- The Uniswap web app will now be on a different network, and you are ready to swap!
