How to swap on the Base Network

Swapping with the Uniswap V3 on Base is the same as swapping on the Ethereum Mainnet.

To swap on Base, follow these steps:

Open Uniswap web app and connect your wallet. Next, select the network drop-down in the upper right hand of the screen.
Select the Base network.
Select the token drop-down.
Search for and select the token you wish to swap/sell. You can browse the token list or search for a token by name or contract address.
Select the token drop-down.
Search for and select the token you wish to swap for. You can browse the token list or search for a token by name or contract address.
Enter the amount you would like to swap, receive, or select the “Max” option.

The “Max” option automatically inputs the total amount of the token you have available in your wallet for swapping.
Select “Swap”.
Review the swap details, and then select “Confirm Swap”.

Your trade will only use Uniswap V3 liquidity pools on the Base -- it will not use a different network’s liquidity, even if a better price is available on a different network.

You can view liquidity and volume on Base pairs at the Uniswap info page.
In your wallet, approve spending for the token you are swapping.
In your wallet, allow the token to be used for swapping. This will require a network fee.

If this is your first time swapping the token with the Uniswap protocol, then you’ll need to approve the token in order to trade it.

For more information on token approvals see our article “What is a token approval?”
In your wallet, confirm the swap.

Once the swap is confirmed, the transaction is submitted to the blockchain (pending).
You will see “Swap success!” and a green checkmark on screen when the transaction is successfully completed.
