Network fee: paid in ETH; on Base it's usually a cent or less.
Selling USDbC 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.
USDbC is the older bridged dollar token on Base; native USDC is issued by Circle and is what most apps and exchanges expect. See USDC vs USDbC.
Orders are settled in batches at one price, so sandwich bots can't front-run you. See how sandwich attacks work.

What does it cost to swap USDbC to USDC 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.
