About
100% air-gapped QR code solution Cold wallet. First hardware wallet Integrated with MetaMask Mobile. By using QR code transmissions, we have eliminated potential malware infiltration risks and delivered a level of transparency that just isn't possible with Bluetooth or USB. A proprietary bank-grade Secure Element ensures your private keys never leave the Keystone. The Secure Element generates a true random number for your private keys and is vital to ensuring your crypto assets are stored in the safest way possible. Our BIP32, BIP39, and BIP44 compliant firmware is also open source. Keystone has pioneered the hardware wallet industry’s first open source Secure Element firmware. It allows you to see how private keys are derived from physically generated entropy (TRNG) and stay entirely confined within the Secure Element. Our hardware wallet application layer, device schematic (circuit diagram), and bill of materials (BOM) are also open source.

About

Verifiable entropy, meaning you know 100% that no one but the TAPSIGNER itself has the private key that controls the Bitcoin. Can be easily and securely backed up into a file. A simple Bitcoin wallet in your pocket. Think of it as a Bitcoin private key on a card! You can sign mobile wallet transactions by tapping the card on your phone. Your mobile wallet provides most of the wallet logic and TAPSIGNER holds the secrets. It's essentially a hardware wallet you can slip inside your regular wallet. TAPSIGNER's lower cost makes hardware wallet features and security available to a wider market around the world. TAPSIGNER is a great way to keep your keys separate from your wallet(s).
