Swap Ethereum to USD Coin. No account, no KYC.

Usually 5 to 20 minutes end to end. Your Ethereum deposit needs 12 confirmations, about 3 minutes at 12-second blocks. The exchange itself takes seconds, and the USDC payout is an ERC-20 transfer that typically confirms within a minute or two of being sent. There is no slow leg on this pair, which is what happens when both assets live on a chain with fast blocks.

The quote floats with the market and carries our 0.5% spread, filling at the rate when your deposit confirms about 3 minutes after you send. That is a short window, so the drift between quote and fill is usually small change. A fixed-rate mode with a 1.0% spread exists at our API level for integrations that need the number locked in advance. Since you are converting into a dollar asset, the floating rate is the better deal most days.

USDC comes with monthly reserve attestations and a US-regulated issuer, which is why compliance-minded businesses and most blue-chip DeFi prefer it. USDT has deeper liquidity in much of the world and the longer track record. Neither is objectively the right answer, and we run corridors into both, so the choice stays with you. If the party you are paying named a specific coin, that decides it for you.

Yes, and that is the most common setup. Both assets use standard Ethereum addresses, so you can paste your own sending address as the payout target and watch the USDC appear where the ETH used to be. Two cautions: paste the raw 0x address rather than an ENS name, since the card validates the hex format, and avoid pointing the payout at an exchange deposit address, which would put your freshly un-KYCed dollars right back behind a verification desk.

Yes. The card lets you switch the payout network to Base, where transfers cost a fraction of mainnet fees. The address format is identical 0x, but the network is not interchangeable: make sure the receiving wallet or service explicitly supports USDC on Base before picking it. For self-custody wallets this is usually a non-issue. For deposits to platforms, check first and save yourself a support ticket.

0.005 ETH. Below that, the payout network fee starts eating a share of the swap that we would be embarrassed to charge. There is no upper limit wired into the card, though unusually large deposits can get a human review before the exchange starts, never after it completes. A small first swap to inspect the receipts is a perfectly good way to size us up.

No. No sign-up, no email, no KYC under the screening threshold. Paste an address, send one payment, and bookmark the order page as your receipt. Screening runs before the exchange begins: pass and it proceeds, fail and your ETH returns to your refund address minus the network fee. One practical note: many countries treat a crypto-to-stablecoin swap as a taxable disposal, and the order page shows exactly the amounts, rate, and hashes a tax tool wants.
