Why is my issuing bank charging me another fee for topping up my fiat wallet?

Some financial institutions may charge a fee on top of the fiat wallet transaction as per their terms and conditions with you. Please contact your issuing bank for more information.

What cards are accepted?

We accept Visa Debit, Mastercard Debit / Maestro that are issued by a US financial institution.

How many cards can I save?

You can save a maximum of 5 cards in the app. For this flow, you’ll only see debit cards listed. If you need to add another card, you will have to delete one of the 5 first.

Why am I not seeing all my cards that I have saved in the app?

Only debit cards are supported in this flow and hence you will not be able to see/choose credit cards that you have saved in the app via other channels.

Why does the app say “Please use a locally issued card” when my card is from the US?

If this is a debit card saved on the app a while back, the information might have been outdated. Please delete and save the card again.

Can I use my card to top up my fiat wallet?

Currently this is not possible - the transaction will be rejected as per policy.

Why was my transaction rejected?

There could be several reasons. A common reason is that the transaction was not completed in time with the correct 3DS response. Another reason could be the financial institution that issued your card may have certain risk policies that restrict the use of your card. In such cases, please contact your card issuer for assistance.

Please also note that using a credit card via Apple Pay or Google Pay might result in declines / transaction failures. In addition, the card issuer might impose additional fees on top of the transaction.
