Bitcoin-only hardware from a US company, now sold as the $349 Passport Prime: keys, two factor codes, security keys and encrypted storage in one device.
Cheap open source device with the most readable screen of its era, and a seed a thief holding it for 15 minutes can extract.

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
KeepKey
What works
- The 3.12 inch OLED screen was the largest of its era and makes address checks easy to read
- Firmware is still shipping: Taproot outputs in 2025, four more chains in 2026, on signed tags
- Each release publishes the expected hash of a reproducible build, so you can verify the binary you flash
- Schematics, PCB layout and bill of materials are published, and the chip is named: no other major vendor goes that far
- One of the cheapest new hardware wallets at $59.95, with simple, sturdy, beginner-friendly hardware
What to watch
- The seed can be extracted with 15 minutes of physical access, and Kraken found that no firmware update can close it
- No secure element, which KeepKey presents as a design choice rather than a gap, so the seed lives in flash on a general purpose chip
- The PIN is 1 to 9 digits, so once the encrypted seed is off the device it is trivial to brute force
- The store advertises free firmware updates for life without linking the release history that backs the promise up
- Releases are infrequent by the standards of the field: none at all between March 2024 and February 2025
Frequently asked questions

Is Foundation Passport or KeepKey bitcoin-only?
Foundation Passport is bitcoin-only; KeepKey supports other assets too. 11 native chains plus EVM tokens by the vendor's own count, with THORChain swaps in the app
Does Foundation Passport or KeepKey carry a warning?
KeepKey: Kraken Security Labs published a voltage glitching attack in 2019 that lifts the encrypted seed off a KeepKey with about 15 minutes of physical access and roughly 75 dollars of equipment, then brute forces the short PIN that protects it. Kraken's own conclusion was that the weakness sits in the device's microcontroller and cannot be closed by firmware. The firmware itself is still shipping; the hardware is the problem, and a BIP39 passphrase is the mitigation.
