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

Tangem Wallet

What works

  • Keys are generated inside a certified chip and never leave it, with no seed phrase to steal by default
  • Sold in sets of two or three, so the backup is a second card rather than a written phrase
  • Nothing to charge, connect or cable up: you tap the card against your phone
  • Tangem states that no Tangem server sits between your card, your phone and the blockchain
  • Buy and swap are built into the app

What to watch

  • No screen, so you verify transaction details on the phone rather than on the device itself
  • Lose every card in the set without having created a seed phrase and the funds are unrecoverable
  • Not bitcoin-only
  • Tangem refuses delivery to 40 named jurisdictions, Colombia, Laos and Vietnam among them
