Cryptnox Wallet
a credit-card-sized hardware wallet that stores keys on an EAL6+ secure element and signs transactions over NFC from a phone.
What is Cryptnox Wallet?
Cryptnox is a hardware wallet built into a credit-card form factor, powered by an EAL6+ certified secure element chip. Users tap the card to a phone over NFC to sign transactions, manage balances, and recover keys to a second card without a seed phrase. The companion mobile app supports Ethereum, Arbitrum, Optimism, Polygon, Avalanche, Polygon zkEVM, and Fantom, and the same cards double as FIDO2 security keys.
