Pros and cons, side by side

Ledger Flex

What works

  • A 2.8 inch E Ink touchscreen at 480 x 600 pixels, more pixels than the larger and dearer Stax screen
  • Same ST33K1M5 secure element, certified to CC EAL6+, as the $399 Stax
  • USB-C, Bluetooth and NFC, so it works with an iPhone as well as a desktop
  • A Ledger Recovery Key is included in the box, so your seed backup is not only on paper

What to watch

  • $249 is more than four times the $59 Nano S Plus for the same certified secure element
  • Closed source firmware, unlike Trezor and BitBox
  • Plastic body with a Gorilla Glass front, where the Stax uses aluminum with stacking magnets

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
