What are the Main Features of Keystone Hardware Wallet?
- With QR codes, you can verify each and every data transmission to ensure that information coming into the Keystone Hardware Wallet contains no trojans or viruses and information going out doesn’t leak private keys or any other sensitive information. In contrast to USB or Bluetooth, QR codes are entirely verifiable as any normal QR code scanner can convert their data contents into human-readable format.
- Keystone Hardware Wallet uses a bank-grade Secure Element to generate true random numbers, derive private and public keys, sign transactions, and protect private keys from being leaked if an attacker has physical access to the device. In addition to ensuring your keys really are your keys by sourcing them from physical entropy, a Secure Element is vital to storing your private keys with the best possible protection from physical attack. A hardware wallet equipped with a Secure Element is a foundation of security long-term hodlers can rely on.
- Keystone Hardware Wallet is the a hardware wallet to have open source Secure Element firmware code, which allows you to verify all core cryptographic operations such as how private keys are generated and contained entirely within the Secure Element. You are able to compile the open source Secure Element firmware and hardware wallet application layer code available on our Github page if you want to verify the genuinity of firmware upgrade packages for Keystone Essential and Pro yourself. We have also released the device schematic circuit diagram.
- The weakest link in an electronic device tends to be the battery because it’s usually only built to last a few years. Keystone batteries are detachable to prevent corrosion damage and both Keystone Essential and Pro come with AAA battery support so you never have to worry about battery failure down the road. Keystone Pro also comes with a rechargeable battery.
