Pros and cons, side by side

Keystone 3 Pro

What works

  • Three secure element chips, against one on Ledger's and Trezor's flagship devices
  • A 4 inch touchscreen that shows full transaction detail, including decoded contract data
  • Fully air-gapped: signing happens over QR codes or microSD, never USB or Bluetooth
  • Fingerprint unlock and anti-tamper protection that wipes data if the case is opened
  • Dice-roll entropy, Shamir backup and BIP-129 multisig, a standard Keystone co-authored

What to watch

  • Not bitcoin-only, so multi-chain parsing code runs on the device
  • Keystone's shipping page claims worldwide delivery and then publishes a 56 country list
  • Air-gapped signing means scanning QR codes for every transaction, which is slower than plugging in a cable
  • A newer brand with a shorter public track record than Ledger or Trezor

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
