Distinctive features of the Keystone Hardware Wallet
You Sign What You See
The transmission of QR codes eliminated the potential risks of malware penetration and provided a level of transparency that is simply not possible with Bluetooth or USB.
EAL 5+Secure Element
A proprietary bank-grade Secure Element ensures your private keys never leave the Keystone Vault. 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. BIP32, BIP39, and BIP44 compliant firmware is also open source.
Firmware 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. Keystone hardware wallet application layer, device schematic (circuit diagram), and bill of materials (BOM) are also open source, soon to be followed by our operating system layer code.
The third-party code audit report is open, the first ever made public by a hardware wallet company.

The Keystone mobile application allows you to track the balance of funds, transaction history, prepare raw transactions for subsequent signing and translation into the blockchain. The wallet is also compatible with Specter, BlueWallet, Electrum, Wasabi Wallet, and Sparrow.
