EAL 5+ Secure Element 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. Detachable Battery Detachable Battery are designed for long term hodlers to better protect their cryptos. People do not have to worry about battery failures anymore. 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. 4-inch Touch Screen The device is super easy to use with a 4-inch touch screen, which can provide you smooth and fantastic user experience. The touch screen maximizes usability to prevent human error. It can also navigate DeFi securely - Keystone's 4-inch display helps protect against the hidden threat of blind signing by giving the user a clear view of transaction details, which they can manually confirm for themselves. Keystone App - Companion App for the Keystone Hardware Wallet The Keystone is completely air-gapped and needs the companion app to connect to blockchain networks. Once you've synced your Keystone with the app, you can see balances, create new transactions, and broadcast signed ones to the network. For your security, we only provide a mobile app. Because of the different voltage in different countries, Keystone wallet can only use 5V1A or 5V2A small charger to facilitate more users. If the charger plug/charger default output voltage exceeds 7v, it will burn out the TVS tube on the battery board, resulting in the charging lamp not lighting up and can no longer be charged.
