Let's say you are going to swap Bitcoin Cash (BCH) for Bitcoin (BTC).
To start the BCH swap process, scroll to the main exchange form above and make sure that BCH 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 Bitcoin Cash (BCH) 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 BCH 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 BCH swap transaction. You will be redirected to the transaction page.
On the transaction page, copy the deposit Bitcoin Cash address and amount into the corresponding fields on "Send" tab/dialog box of your BCH crypto wallet, or simply scan the QR code if you are using a mobile wallet. Send the Bitcoin Cash payment.
Track the status of your BCH 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.
