About

Passport Prime is open-source human-authority hardware combining a Bitcoin wallet, offline 2FA codes, NFC/USB security keys, 50GB encrypted storage and sandboxed KeyOS apps.

Analysis

OVERVIEW

Foundation Passport signs transactions entirely through QR codes, with no USB or Bluetooth connection at all, and raised a $7M Series A from SV Angel, Ten31 and Lightning Ventures around an open source hardware and firmware design.

LIMITS

Foundation Devices is a US entity, which the record places in Five Eyes jurisdiction even though the device itself holds no keys or server-side data; the record also lists no named third-party audit and notes a hardware purchase can expose a shipping address.

USEFUL FOR

Cold storage and QR-based signing where open source hardware verification matters more than phone-connected convenience.
