Good to know
- Network fee: paid in ETH; on Base it's usually a cent or less.
- Selling USDC can often be done with just a signature: USDC supports signed approvals, and the network cost is taken from the token you sell. If the panel asks for an approval transaction, you'll need a little ETH.
- Orders are settled in batches at one price, so sandwich bots can't front-run you. See how sandwich attacks work.
Questions
What does it cost to swap USDC to ETH on Base?
The network cost (usually a cent or less) and our 0.5% service fee, both included in the quote you see before signing.
Why is my swap protected from MEV?
You sign an order instead of sending a public swap. Orders are settled together at one price by competing solvers, so bots have nothing to sandwich.
Do I need an account?
No. Connect your own wallet; there's no sign-up and we never hold your funds.
What if the swap doesn't fill?
If the price moves past your limit, a signed order simply expires and you keep your tokens.
