Topping up a card you already have is quick. Card top-ups are made with your U9 balance, so if you do not have U9 yet, swap USDT or USDC into U9 first.
- Open the app and go to Card details, then tap Top up.
- Enter the top-up amount and check the fees shown.
- Follow the on-screen instructions to confirm the transaction.
- Once the top-up is complete, you can check the arrival status in your card balance and in Transaction History.
The U9 top-up fee is 0%, and any network fee is shown before you confirm.
