The Cryptnox Dual Hardware Wallet is a next-generation smartcard wallet designed for secure, offline management of your crypto assets. Built with a tamper-resistant EAL6+ secure element, it allows you to sign blockchain transactions via NFC without ever exposing your private keys.
Each pack includes two smartcards — a primary and a backup — both initialized together in seconds with the same private key. There’s no need to write down or store a recovery phrase: simply keep your second card in a safe place.
Compatible with Bitcoin, Ethereum, Tron, and all EVM-compatible blockchains, the Cryptnox Wallet app makes it easy to send, receive, swap, and sign transactions offline — whether you’re managing tokens, NFTs, or DeFi operations.
As an added feature, each card also supports FIDO2 authentication for secure logins on major web services. This feature is completely separate from the crypto wallet functionality.
Includes two smartcards seeded simultaneously for backup without exposing any recovery phrase, or seeded individually with a BIP39 seed (12/24 words)
Sign transactions securely via NFC without connecting your private key to the internet.
Private keys are stored in a Common Criteria certified secure element, designed to resist physical and logical attacks.
Compatible with WalletConnect and QR Wallet standards MetaMask for seamless integration with DeFi platforms and NFT marketplaces.
Supports Bitcoin, Ethereum, Tron, Polygon, Avalanche, Binance Smart Chain, Arbitrum, Optimism, and other EVM chains.
Manage your wallets with the Cryptnox mobile app (iOS/Android), or use the command-line tool for advanced control on desktop.
Use the same card as a FIDO2 security key for passwordless login or 2FA on platforms like Google, GitHub, or Binance.
