Network fee: paid in ETH; on Base it's usually a cent or less.
Selling native ETH needs one on-chain transaction, so keep a little ETH unsent for the network fee.
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 ETH 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.
