Description
We have eliminated malware infiltration risks by using QR code transmissions. This has allowed us to deliver a level of transparency that isn't possible via Bluetooth or USB. Find out how to verify every transmission that enters or leaves the Keystone. Secure Element, a proprietary bank-grade security element, ensures that your private keys are never lost from the Keystone. The Secure Element generates an authentic random number for your private key and is essential to ensure your crypto assets are kept in the most secure manner possible. Open source firmware that is compliant with BIP32, BIP39 and BIP44 is also available. Keystone pioneered the first open-source Secure Element firmware for hardware wallets. It allows you to see how private key derived from physical generated entropy (TRNG), and it remains completely contained within the Secure Element. Open source are our hardware wallet application layer (circuit diagram), device schematic (circuit diagram) and bill of materials(BOM).
