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

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

Frequently asked questions

Is KeepKey or Ledger Nano X better?

Ledger Nano X rates higher on our rubric: 3.9 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 Ledger Nano X?

KeepKey, at $59.95 against $79, on each maker's own store price as of the review date.

Is KeepKey or Ledger Nano X 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. Ledger Nano X: Bitcoin plus more than 500 assets in the Ledger Wallet app, and thousands more through third party wallets.

Does KeepKey or Ledger Nano X 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.
