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 Nano X

What works

Bluetooth and a built-in battery let you sign from a phone with no cable attached
Cheapest Ledger with mobile signing at $79, marked down from $99 on Ledger's own store
Keys stay inside an ST33J2M0 secure element certified to CC EAL5+
Proven in the field since it shipped in May 2019, with years of firmware updates behind it

What to watch

The 128 x 64 pixel screen turns checking a long address into a multi step scroll
Closed source firmware, unlike Trezor and BitBox
The battery is not user replaceable, which caps how long it stays useful for cable free signing
The optional Ledger Recover service introduced in 2023 drew criticism from users who object to any firmware pathway that can export an encrypted seed
