SECURE CHIP  

A secure chip is used for seed protection, brute-force prevention and device password hardening.

OLED SCREEN  

Verify 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
