OLED SCREENVerify on the screen of the device what you are about to confirm, including all transaction details before signing.

 
Features:

On-device password entry
Open sourced and deterministic builds as we live the motto "Don't trust, verify"
Secure verification of transactions and other data via display on screen and user gesture confirmation
Device attestation to detect counterfeits
Externally audited firmware
Encrypted USB communication between device and app with Noise protocol to avoid eavesdropping
Encrypted seed stored on the MCU, protected by both the secure chip and user-chosen device password
Multiple sources of entropy for seed generationMonotonic counter in secure chip to avoid brute force attacks by limiting total attempts
Password stretching in secure chip to avoid brute force attacks by making attacks take a very long time
Bootloader accepts only firmware signed by Shift Cryptosecurity
Bootloader can display the hash of the firmware before running it for binary transparency
Bootloader prevents firmware downgradesProtection against nonce covert channel attacks
Optional BIP39 passphrase
