Base Token Swap Guide

Base mainnet uses chain ID 8453 and ETH for gas.

Open Base swap

Before you swap on Base

1. Check that your wallet is set to Base mainnet and chain ID 8453.
2. Keep enough ETH on Base to cover network fees.
3. Verify the token contract and network in BaseScan before you sign a transaction.

Base uses the Ethereum Virtual Machine. If your wallet already has ETH on Ethereum mainnet or another network, that balance is separate from your Base balance.
