Pros and cons, side by side

Foundation Passport

What works

Bitcoin only, with open source apps and a published independent audit quote
KeyOS sandboxes apps so a compromised app cannot reach the master keys
Bluetooth runs through a dedicated chip rather than the processor holding your secrets
Envoy is distributed on F-Droid as well as the App Store and Google Play
Assembled in the USA, which matters if supply chain provenance is part of your threat model

What to watch

$349 is well above most bitcoin-only signers
Passport Core, the cheaper earlier model, has been discontinued
No reachable country list: the terms name a Shipping Policy that is not published anywhere, and Foundation may refuse an order over export or sanctions concerns
A smaller company with a shorter public track record than Ledger, Trezor or Coinkite

Trezor Safe 3

What works

EAL6+ certified secure element and fully open source firmware at $59
PIN and passphrase are typed on the device, never on a possibly compromised computer
Multi-share (Shamir) backup and FIDO2 two factor support are built in
A Bitcoin-only edition is sold alongside the multi coin version

What to watch

Two buttons and a 0.96 inch monochrome screen make checking a long address slower than on a touchscreen
iOS is view only: no setup, sending or device management from an iPhone
SecurityWeek reported in August 2026 that a breach at fulfilment partner ShipMonk exposed about 14,000 customers' shipping details
Trezor publishes no list of countries it ships to, only a checkout drop-down
