Blockstream Jade4.3Bitcoin-only

Bitcoin-only line from $79 to $149 that ships no secure element on purpose: a locked Jade holds nothing worth extracting.

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

Blockstream Jade

What works

  • Bitcoin only, with both firmware and hardware published as open source
  • Three tiers from $79 to $149 sharing one firmware and one security model
  • Genuine Check attestation lets you verify the device was actually made by Blockstream
  • Jade Plus signs fully air-gapped over QR codes and reads an SD card
  • Blockstream fixed the DARKNAVY report in three weeks and published a full public disclosure

What to watch

  • No certified secure element, which is a deliberate tradeoff but still a difference from Ledger, Trezor and BitBox
  • Firmware 1.0.24 through 1.0.36 carried a stack overflow that a compromised host could use to crash the device, and 1.0.35 and earlier could allow limited code execution
  • Jade Core has no camera, so air-gapped QR signing needs the Plus
  • Free international shipping is advertised with no country list behind it, and you may owe import fees

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

Is Blockstream Jade or KeepKey bitcoin-only?

Blockstream Jade 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 Blockstream Jade 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.
