KeepKey vs Ledger
Choose KeepKey if you want firmware that is fully open source and reproducible, a wide 256 × 64 screen, and built-in no-KYC swaps in KeepKey Desktop, and you are willing to use a passphrase for protection against physical theft.
Choose Ledger if you want a certified secure element for physical-attack resistance, Bluetooth for phone use, a touchscreen (Flex, Stax, Nano Gen5), or a coin that is not on KeepKey's supported list.
Spec comparison
| Spec | KeepKey | Ledger Nano S Plus | Ledger Nano X |
|---|---|---|---|
| Screen | 256 × 64 px monochrome OLED on the front face; every address and amount is shown on the device | 1.1" monochrome OLED, 128 × 64 px | 1.1" monochrome OLED, 128 × 64 px |
| Connectivity | USB (micro-B), wired only. No Bluetooth, no NFC, no battery | USB-A to USB-C, wired only; no battery | USB-A to USB-C and Bluetooth; battery up to 5 hours of normal use |
| Secure element | None, by design. General-purpose STM32F205 microcontroller with public datasheets. Physical fault-injection attacks can extract the encrypted seed; a BIP39 passphrase (never stored on the device) protects against that. Security model | Yes: ST33K1M5, CC EAL6+ | Yes: CC EAL5+ |
| Open-source firmware | Yes. Firmware is LGPLv3 on GitHub; each release publishes a reproducible-build SHA-256 you can check | Partly. Ledger says its Ledger Wallet app is open source (MIT); low-level secure element code is not published. Ledger | Same as Nano S Plus. Ledger |
| Chains / assets | Native signing for a defined chain list: Bitcoin and other UTXO coins, Ethereum and EVM chains (plus ERC-20 tokens), Cosmos, THORChain, Maya, XRP, Solana, TRON, TON and more. Full list | 500+ coins in Ledger Wallet; thousands more via third-party wallets (per Ledger) | Same as Nano S Plus (per Ledger) |
| Companion app | KeepKey Desktop (macOS, Windows, Linux) with no-KYC swaps routed across THORChain, Mayachain, Relay, 0x, ChainFlip and ShapeShift. KeepKey Mobile (iOS) and a Chrome extension that connects web apps to KeepKey Desktop | Ledger Wallet app | Ledger Wallet app |
| Price | $59.95 at keepkey.com/store (live price) | $59 (Ledger US shop, as of Sept 2026) | $99 (Ledger US shop, as of Sept 2026) |
Ledger specs from the official Ledger comparison and product pages, accessed September 24, 2026. Ledger also sells touchscreen models (Flex, Stax, Nano Gen5) with E Ink screens, USB-C, Bluetooth and NFC; the Flex was listed at $249. Prices change, so check each maker's store.
The secure element tradeoff
This is the real difference. Ledger stores keys in a certified secure element chip, which is built to resist physical probing. Ledger says an agreement with the chip maker prevents it from publishing the low-level code for that chip.
KeepKey takes the other route: a general-purpose microcontroller and firmware you can read and rebuild yourself. The cost is that someone who steals your KeepKey and has specialist equipment and time can extract the encrypted seed. The fix is a BIP39 passphrase: it is never stored on the device, so a seed pulled from the chip does not open a passphrase-protected wallet. Read the full KeepKey security model.
Against the more common threat, malware on your computer, both devices work the same way: the transaction is shown on the device screen, and nothing is signed until you confirm it on the device.
Questions
- Is KeepKey or Ledger more secure?
- They make different tradeoffs. Ledger uses a certified secure element (CC EAL6+ on the Nano S Plus, CC EAL5+ on the Nano X, per Ledger), which adds resistance to physical attacks, but part of its low-level code is not public. KeepKey has no secure element: its firmware is fully open source and reproducible, and a BIP39 passphrase protects funds if someone physically extracts the seed. Against remote malware, both show the transaction on the device screen for you to confirm.
- Does KeepKey have a secure element like Ledger?
- No. KeepKey uses a general-purpose STM32F205 microcontroller by design, so every part of the firmware can be inspected. An attacker with physical access, specialist equipment and time can extract the encrypted seed; using a BIP39 passphrase, which is never stored on the device, keeps those funds out of reach. See docs.keepkey.com/docs/security.
- Is KeepKey cheaper than Ledger?
- Check the live KeepKey price at keepkey.com/store. As of September 2026, Ledger listed the Nano S Plus at $59, the Nano X at $99 and the Flex at $249 on its official US shop.
- Can I move from Ledger to KeepKey?
- Yes, but the safest path is to set up a new KeepKey with a fresh recovery phrase and send your funds to it, rather than typing an existing recovery phrase into a new device.
- Does KeepKey have Bluetooth?
- No. KeepKey connects over USB only and has no battery, Bluetooth or NFC. Ledger lists Bluetooth on the Nano X, Flex, Stax and Nano Gen5.
