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

Tangem Wallet

What works

Keys are generated inside a certified chip and never leave it, with no seed phrase to steal by default
Sold in sets of two or three, so the backup is a second card rather than a written phrase
Nothing to charge, connect or cable up: you tap the card against your phone
Tangem states that no Tangem server sits between your card, your phone and the blockchain
Buy and swap are built into the app

What to watch

No screen, so you verify transaction details on the phone rather than on the device itself
Lose every card in the set without having created a seed phrase and the funds are unrecoverable
Not bitcoin-only
Tangem refuses delivery to 40 named jurisdictions, Colombia, Laos and Vietnam among them
