Pros and cons, side by side

KeepKey

What works

  • The 3.12 inch OLED screen was the largest of its era and makes address checks easy to read
  • Firmware is still shipping: Taproot outputs in 2025, four more chains in 2026, on signed tags
  • Each release publishes the expected hash of a reproducible build, so you can verify the binary you flash
  • Schematics, PCB layout and bill of materials are published, and the chip is named: no other major vendor goes that far
  • One of the cheapest new hardware wallets at $59.95, with simple, sturdy, beginner-friendly hardware

What to watch

  • The seed can be extracted with 15 minutes of physical access, and Kraken found that no firmware update can close it
  • No secure element, which KeepKey presents as a design choice rather than a gap, so the seed lives in flash on a general purpose chip
  • The PIN is 1 to 9 digits, so once the encrypted seed is off the device it is trivial to brute force
  • The store advertises free firmware updates for life without linking the release history that backs the promise up
  • Releases are infrequent by the standards of the field: none at all between March 2024 and February 2025

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

Frequently asked questions

Is KeepKey or Keystone 3 Pro better?

Keystone 3 Pro rates higher on our rubric: 4.4 against 2.6 for KeepKey. The rating follows the product rubric published on our about page; the rows above set custody, price and platforms side by side so you can check it.

Which is cheaper, KeepKey or Keystone 3 Pro?

KeepKey, at $59.95 against $149, on each maker's own store price as of the review date.

Is KeepKey or Keystone 3 Pro bitcoin-only?

Neither: both support assets beyond bitcoin. KeepKey: 11 native chains plus EVM tokens by the vendor's own count, with THORChain swaps in the app. Keystone 3 Pro: Multi-asset: Keystone counts more than 5,000 coins and tokens and over 45 compatible software wallets.

Does KeepKey or Keystone 3 Pro carry a warning?

KeepKey: Kraken Security Labs published a voltage glitching attack in 2019 that lifts the encrypted seed off a KeepKey with about 15 minutes of physical access and roughly 75 dollars of equipment, then brute forces the short PIN that protects it. Kraken's own conclusion was that the weakness sits in the device's microcontroller and cannot be closed by firmware. The firmware itself is still shipping; the hardware is the problem, and a BIP39 passphrase is the mitigation.
