Pros and cons, side by side

BitBox02

What works

  • Fully open source firmware, in a Multi edition and a true Bitcoin-only edition
  • Dual chip design, with an EAL6+ certified secure chip on the Nova
  • microSD backup makes setup and recovery fast, and writing down the words is optional
  • Three built-in on-ramps (Pocket Bitcoin, MoonPay, BTC Direct) send coins straight to the device
  • The Nova works with an iPhone or iPad over Bluetooth

What to watch

  • No touchscreen: confirmations happen on a small OLED with touch sliders
  • The original BitBox02 has no iOS support, so an iPhone user needs the Nova
  • BitBox publishes no shipping country list, only regional tiers and a duty policy
  • Shipping cost and any unpaid import duties are only shown at checkout

Ledger Flex

What works

  • A 2.8 inch E Ink touchscreen at 480 x 600 pixels, more pixels than the larger and dearer Stax screen
  • Same ST33K1M5 secure element, certified to CC EAL6+, as the $399 Stax
  • USB-C, Bluetooth and NFC, so it works with an iPhone as well as a desktop
  • A Ledger Recovery Key is included in the box, so your seed backup is not only on paper

What to watch

  • $249 is more than four times the $59 Nano S Plus for the same certified secure element
  • Closed source firmware, unlike Trezor and BitBox
  • Plastic body with a Gorilla Glass front, where the Stax uses aluminum with stacking magnets
