Step 1: Deposit USDT or USDC into your app wallet
In your wallet, choose the coin and network you want to deposit, copy the receiving address, and send the funds from your exchange or other wallet. Make sure you send on the same network.
Step 2: Swap to U9 on the Trade page
-
Tap Trade on the app's home page and select U9 at the top.
-
In the Pay field, tap the coin and choose the USDT or USDC you hold. Your wallet lists assets by network, for example USDT on TRON or USDC on BSC.
-
Enter an amount, or tap Max. The Receive field shows how much U9 you will get (1 USDT ≈ 1 U9).
-
Check the trading fee and the gas fee.
-
Tap Buy U9 and confirm.
-
Once the U9 arrives, you can see it in your wallet and top up your U9 Card.
Note: 1) If you turn on Pay gas with USDT, the gas fee is paid in USDT. 2) If you see "The amount plus gas fee exceeds your available balance", lower the amount so there is enough left for the gas fee. 3) A single purchase of 100 U9 or more earns a 0.1 ABEL airdrop, once per account, which you can use for future gas fees. The details shown in the app apply.
