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

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

Frequently asked questions

Is KeepKey or Trezor Safe 3 better?

Trezor Safe 3 rates higher on our rubric: 4.5 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 Trezor Safe 3?

Trezor Safe 3, at $59 against $59.95, on each maker's own store price as of the review date.

Is KeepKey or Trezor Safe 3 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. Trezor Safe 3: Multi edition manages thousands of coins and tokens; a separate Bitcoin-only edition is also sold.

Does KeepKey or Trezor Safe 3 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.
