The Cryptnox hardware wallet is a high-security solution based on smartcard technology. It supports BIP32 and BIP39 standards, making it compatible with most blockchain networks.
You can perfectly access the Cryptnox wallet mobile application without a card as long as a card was linked to the application previously. Without a card, you can check current balances, but a card is required to perform transactions.
Absolutely. The mobile application is compatible with the WalletConnect standard which allows you to connect to most online web3 dapp. Just choose WalletConnect as a wallet option, scan the QR code with your phone app, follow the instructions on the screen, and your wallet is connected. You can then perform Defi transactions and event mint or transfer NFT.
Storing your Pin and Puk together with either your backup card if you performed a Dual Card Setup, or a copy of your BIP39 (12 or 24 words) seed if it was externally injected, is a major security requirement. For protection, the Puk is required for reset.
You can only perform a Dual Card Setup with a pair or cards that was provided in the same pack. They should have a difference of one unit in the printed serial number.
Absolutely. If your seed originates from a BIP32/BIP39 wallet, you can inject it in a Cryptnox Harware Wallet card. For this, when starting the application, please choose “Other Options”, and “mnemonic”, and simply follow the instructions. You will be prompted to type in you 12 or 24 words seed.
The Pin and the Puk work in a similar way for accessing a phone sim card. The Pin is generally required for executing a transaction on other Cryptnox Card compatible applications.
The Puk has administrative privileges, and is required for pairing your card with the biometrics of your phone, or for a reset.
Absolutely not. The wallet is always created by the owner after receiving it, and a Cryptnox card is always required to perform transactions. It has no way to have access to your wallet.
The Cryptnox Hardware Wallet cards are compatible with bitcoin and Ethereum Virtual Machine (EVM) based blockchains. Should an EVM based network or coin not be originally listed in the Cryptnox Wallet application, it can be manually added.
Delivery time can vary depending of location and sale channels. In general, it can take between one to seven days.
When starting the application, simply tap on “Dual Card Setup”, and follow the instructions. Both your cards will be ready to use in seconds! If necessary, you can also check our quick startup guide.
The Cybersecurity firm Cure53 was appointed to perform a security analysis of the card firmware.
