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

Trezor Safe 3

What works

EAL6+ certified secure element and fully open source firmware at $59
PIN and passphrase are typed on the device, never on a possibly compromised computer
Multi-share (Shamir) backup and FIDO2 two factor support are built in
A Bitcoin-only edition is sold alongside the multi coin version

What to watch

Two buttons and a 0.96 inch monochrome screen make checking a long address slower than on a touchscreen
iOS is view only: no setup, sending or device management from an iPhone
SecurityWeek reported in August 2026 that a breach at fulfilment partner ShipMonk exposed about 14,000 customers' shipping details
Trezor publishes no list of countries it ships to, only a checkout drop-down
