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

SafePal S1

What works

  • No USB data, WiFi, Bluetooth or NFC: the only channel in or out is a QR code on a camera
  • SafePal's budget cold storage line, positioned below the newer Bluetooth X1
  • Broad asset support with swap, buy and DeFi features for people who hold more than bitcoin
  • SafePal accepted an outside security report from Kraken Security Labs and shipped a fix

What to watch

  • Not bitcoin-only, and the companion app is a broad crypto app rather than a focused signer
  • The February 2021 Kraken disclosure showed the firmware update check could be downgraded without the user noticing
  • Verification happens on a small screen, which makes careful address checking slower
  • SafePal publishes no shipping country policy, pointing at a reseller network instead
