Let's say you are going to swap THETA (THETA) for Bitcoin (BTC).
To start the THETA swap process, make sure that BTC is selected in the dropdown list to the right of "You send" box, and THETA is chosen in the dropdown list to the right of "You receive" box.
Enter the amount of Bitcoin (BTC) you are going to swap into "You send" box. Wait a bit for the recalculation to complete and check the estimated amount of THETA (THETA) in "You receive" box.
Enter the receiving THETA wallet address and, optionally, the refund BTC wallet address.
Click "Exchange" button to create the THETA swap transaction. If all entered values are correct and valid, you will be redirected to the transaction page.
On the transaction page, copy the deposit Bitcoin address and amount into the corresponding fields on "Send" tab/dialog box of your crypto wallet (or simply scan the QR code if you are using a mobile wallet). Send the Bitcoin payment.
Track the status of your BTC to THETA swap on the transaction page. Typically, most exchanges take from 5 to 60 minutes. However, in case of a crypto network congestion, the exchange process could take longer than that.
When the swap status displays "Finished", you can check your receiving THETA wallet to make sure you have a new incoming THETA transaction.
