Let's say you are going to swap USD Coin (USDC) for Bitcoin (BTC).
To start the USDC swap process, scroll to the main exchange form above and make sure that USDC is selected in the dropdown list to the right of "You send" box, and BTC is chosen in the dropdown list to the right of "You receive" box.
Enter the amount of USD Coin (USDC) you are going to swap into "You send" box. Wait a bit for the recalculation to complete and check the estimated amount of Bitcoin (BTC) in "You receive" box.
Enter the receiving BTC wallet address and, optionally, the refund USDC wallet address. Certainly, the best way to avoid any mistakes at this step is to copy and paste the crypto address(es).
If all entered values are correct and valid, the color of "Exchange" button will change from grey to green. Click the button to create the USDC swap transaction. You will be redirected to the transaction page.
On the transaction page, copy the deposit USD Coin address and amount into the corresponding fields on "Send" tab/dialog box of your USDC crypto wallet, or simply scan the QR code if you are using a mobile wallet. Send the USD Coin payment.
Track the status of your USDC to BTC swap on the transaction page. Typically, most exchanges take from 3 to 60 minutes. However, in case of a crypto network congestion, the exchange process could take longer than that.
As soon as the swap status displays "Finished", you can check your receiving Bitcoin wallet to make sure you have a new incoming BTC transaction.
