Cryptnox
A hardware wallet in a credit-card form factor that signs transactions with an NFC tap and skips the seed phrase entirely.
What is Cryptnox?
Cryptnox is a hardware wallet built into an EAL6+ secure-element smart card. Users tap the card to a phone running the Cryptnox app to sign transactions, manage balances, and connect to dapps via WalletConnect. Backups happen by writing keys to a second card instead of writing down a 12- or 24-word recovery phrase. Built by a Geneva-based team and certified by the FIDO Alliance.
