Pros and cons, side by side

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

OneKey

What works

  • Four signing models from $79 to $278, including a bitcoin-only Classic 1S Pure
  • Companion app on iOS, Android, Windows, macOS, Linux and as a browser extension
  • Firmware and apps are developed in public on GitHub
  • Faulty devices are replaced rather than repaired, so no repair shop handles your hardware

What to watch

  • Not bitcoin-only outside the Classic 1S Pure bitcoin edition
  • Specifications vary widely across the range, so the brand name alone tells you little about the device you are buying
  • Researchers opened a OneKey Mini in 2023 with physical access and lab hardware, which OneKey patched but which is part of the brand's record
  • No published shipping country policy: the help center article that should carry one returns a 404
  • A shorter public track record than Ledger, Trezor or Coinkite

Frequently asked questions

Is KeepKey or OneKey better?

OneKey rates higher on our rubric: 3.7 against 2.6 for KeepKey. The rating follows the product rubric published on our about page; the rows above set custody, price and platforms side by side so you can check it.

Which is cheaper, KeepKey or OneKey?

KeepKey, at $59.95 against $99, on each maker's own store price as of the review date.

Is KeepKey or OneKey bitcoin-only?

Neither: both support assets beyond bitcoin. KeepKey: 11 native chains plus EVM tokens by the vendor's own count, with THORChain swaps in the app. OneKey: Multi-asset across the line, with a bitcoin-only Classic 1S Pure sold at the same $79 as the standard model.

Does KeepKey or OneKey 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.
