Payment failures can happen for a variety of reasons. In most cases, they're caused by your bank, your payment method, or additional security checks.
This article explains the most common reasons why a payment may fail and what you can do to successfully complete your transaction.
Common reasons why a payment may fail
Your Bank Declined the Transaction
Some banks restrict or block cryptocurrency-related transactions as part of their internal policies or fraud prevention measures.
Unfortunately, Mercuryo cannot override your bank's decision.
What you can do:
- Contact your bank to confirm why the payment was declined.
- Ask whether cryptocurrency transactions are supported.
- If possible, try another supported bank card.

Insufficient Funds
Your payment may fail if there aren't enough funds available on your card or account.
Please ensure you have enough available balance to cover:
- The purchase amount
- Any applicable bank fees or currency conversion fees
Incorrect Card Details
Double-check that you've entered:
- The card number
- Expiry date
- CVV/CVC security code
- Cardholder name
Even a small mistake can cause your payment to fail.
Your Card Has Expired or Is Unsupported
Make sure your payment card:
- Has not expired
- Supports online payments
- Supports cryptocurrency purchases (if allowed by your bank)
Some prepaid, virtual, or corporate cards may not be supported.
3D Secure Authentication Was Not Completed
Some banks require additional authentication, such as 3D Secure, before approving a payment.
If authentication isn't completed successfully, your payment may fail.
Try the payment again and make sure you complete all authentication steps requested by your bank.
Your Bank Flagged the Payment for Security Reasons
Your bank may temporarily block a transaction if it appears unusual or requires additional verification.
This is a security measure designed to protect your account.
In this case, contacting your bank is usually the fastest way to resolve the issue.
Temporary Technical Issues
Occasionally, payments may fail because of temporary issues with:
- Your bank
- The payment network
- Mercuryo's payment provider
If this happens, please wait a few minutes and try again.
How to Troubleshoot a Failed Payment
If your payment wasn't successful, we recommend trying the following:
- Check that your card details are correct.
- Make sure you have sufficient available funds.
- Complete any required 3D Secure authentication.
- Contact your bank to confirm they support cryptocurrency transactions.
- Try another supported payment card.
- If available, use a different payment method.
If the problem continues, contact our Support team.
