About
Air-gapped Bitcoin hardware signer transferring data by QR, paired with the Envoy companion app.
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.
