Pros and cons, side by side

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

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
