A3 Swap
Swap supported assets on Base from your own wallet. Read the route and conditions before you sign.
Know what you exchange
Learning examples only. They do not change the form or request a signature.
ETH → USDC converts native ETH into USDC on Base. ETH input does not need ERC-20 approval. Enter an amount above for a real, current quote — no fixed exchange rate is promised.
Every cost, separately
The live fee breakdown and exact minimum appear inside the form with your quote. These notes explain the rules, not another quote.
