Wallet cards put to the test

The test for this group begins with its defining claim. Does the card spend from a wallet whose keys only you hold, with funds untouched until payment and the provider converting at the till? Cards that pass are checked further.

After that come the measurable parts: what the card costs, which coins and networks fund it, who is able to order it and how the issuer behind it is built.

The check of risk is the last step. Self-custody does not make that risk vanish: a seed phrase once lost stays lost, and the issuer can freeze the card. Each result shows where it found that boundary.
