Before you start this ultimate guide, you must have a verified account. To create an account and verify it on OKX download the app from here:
Once you have downloaded the official app on your smartphone and created an account, make sure that you have verified it and added funds to your OKX account.
Make sure that your OKX account has the exact amount you want to pay. If your funds are not enough then add more so you can pay the exact amount for the service you need.
Click on the icon at the right bottom of the screen (Assets).
Click on "Withdraw".
Choose "Withdraw crypto".
Click on "USDT" Balance you have.
Click on "Exchanges or wallets".
Choose "TRON (TRC20)" as we recommended for OKX users.
Enter "Recipient Wallet Address" and "Amount" that you will pay.
Click "Submit" and complete forward.
You can find it on the service form, click on the "Network" tab to find it.
Or visit BIGO Pay page to see Recipient Information.
NOTE: You must copy the same "Recipient Wallet Address" of the Network you want to pay with.
