Top-Up Methods
The Mercuryo Spend Virtual Mastercard does not require pre-loading or traditional top-ups. Instead, it connects directly to a user's non-custodial crypto wallet, and when a purchase is made, the selected cryptocurrency (from 40 supported options) is automatically converted to euros at the point of sale with a 0.95% conversion fee. This process ensures that users retain self-custody of their assets until the actual transaction, with no need to transfer funds to the card provider ahead of spending. There are no minimum or maximum top-up amounts, but a €40,000 monthly spending cap applies, and all conversions are immediate using the integrated app or compatible non-custodial wallet interfaces. The card is available exclusively to EEA residents and requires KYC/AML verification before use.
Self-Custody True Self-Custody
This card allows users to keep full control of their crypto assets and private keys right up to the moment they make a purchase. There's no need to pre-load funds onto a platform or transfer crypto to a central service—spending happens directly from your non-custodial wallet, with crypto converted to euros on the spot when you pay. Because users never hand over custody of their funds to Mercuryo or Quicko, your assets remain yours and fully accessible even if the card provider ceased operations. Practical benefits include strong alignment with self-custody principles and added security, but you must pass KYC verification to use the card, and it is currently limited to EEA residents. The main limitation is that only virtual cards are available and purchases are subject to a small conversion and maintenance fee. This approach prioritizes user control and security, while enabling broad Mastercard merchant access and seamless mobile wallet integration.
