If your balance isn't enough to cover the transaction, the "Continue" button will be greyed out and on the confirmation screen will show "Increase balance". Tapping it opens a pop-up with two options:
- Deposit — takes you to the fiat deposit page (if paying with VND) or the Crypto deposit page (if paying with a token).
- Transfer — on App, jumps to the transfer page; on Web, opens the transfer pop-up.
Once your balance is topped up, you can complete the order.
