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

Ledger Stax

What works

  • The 3.7 inch curved E Ink touchscreen is the largest display Ledger sells, so addresses read in one view
  • Same ST33K1M5 secure element, certified to CC EAL6+, as every other current Ledger
  • USB-C, Bluetooth and NFC, plus wireless Qi charging that no other Ledger has
  • Ships with a Ledger Recovery Key and a protective magnet shell included in the box

What to watch

  • At $399 it costs nearly seven times the $59 Nano S Plus for the same certified secure element
  • The $249 Flex has the same chip and more screen pixels, at 480 x 600 against 400 x 670
  • Closed source firmware, unlike Trezor and BitBox
