Ledger Nano X

The Ledger Nano X is a Nano-format hardware wallet with Bluetooth, released by Ledger in 2019. It connects over USB-C or Bluetooth BLE 5.2, has a 1.1-inch monochrome OLED, a battery Ledger rates at up to 5 hours of normal use, and an ST33J2M0 secure element that holds the private keys. On 14 October 2026 it was listed at $99 on Ledger’s online shop.

Who is the Ledger Nano X for?

It fits people who:

• want to approve transactions from a phone without a cable, or switch between phone and computer;
• want a small device with Ledger Wallet’s coin range;
• accept a battery, a radio and Ledger’s partly closed firmware.

It fits fewer people who:

• want no wireless interface: the Nano S Plus is USB-C only, and air-gapped wallets sign without a cable or radio data link, though some keep those interfaces for other modes;
• want a touchscreen, which the Nano Gen5 adds;
• want a Shamir (SLIP-39) backup, which Ledger’s pages we checked do not document for this model.

What is the Ledger Nano X like to use?

The display is a 1.1-inch monochrome OLED at 128 x 64 pixels, not a touchscreen; Ledger’s model comparison describes it as screen plus buttons. The body is 72 x 18.6 x 11.7 mm and 34 g, so it is longer, thicker and 13 g heavier than the Nano S Plus. The battery lets it run without a cable when paired with a phone.

Is the Ledger Nano X Bluetooth connection safe?

In its Bluetooth security model (January 2019), Ledger says only public data travels over Bluetooth and the seed and private keys are never exposed to the Bluetooth stack. A separate microcontroller relays data to the secure element. Pairing uses numeric comparison, which Ledger notes may be missing on older Android versions, and the link is protected with AES-based encryption. Even if the connection were compromised, Ledger says no signature is issued without confirmation on the device.

The protection is therefore the on-device check: a compromised phone can still propose a bad transaction, and the defence is reading the address and amount on the Nano X screen. Ledger says Bluetooth can be switched off in favour of USB-C. These are Ledger’s statements; we found no independent audit of the Nano X Bluetooth stack.

What did the 2020 Kraken research find on the Nano X?

On 8 July 2020 Kraken Security Labs published two attacks on Nano X units tampered with before reaching the buyer, for example in shipping. Both reflashed the non-secure STM32WB55 microcontroller, not the secure element:

• one made the device act as a USB keyboard that sent keystrokes to the host computer;
• the other could switch off the display while the buttons still worked, so a malicious app could trick a user into approving a transaction they could not see.

Kraken did not report extracting a seed or reaching the secure element. Per its article, the reflash had to happen before the first app was installed, because that step disables debugging. Kraken reported the issue to Ledger on 9 April 2020.

Ledger’s bulletin LSB-013 says firmware 1.2.4-2 has the secure element check the integrity of the whole microcontroller at each boot, and that debug interfaces are disabled on newly made devices. Ledger’s view is that the microcontroller can be fully compromised while funds stay secure. Kraken advised buying from trusted stores and verifying every transaction on the device screen.

Is the Ledger Nano X open source?

Partly. Ledger says its operating system and software are “95% OpenSource and/or available”. The closed part is the low-level code that drives the secure element’s hardware, which Ledger says its agreement with STMicroelectronics keeps private. More in Is Ledger safe?.

How do you back up and restore a Ledger Nano X?

The device creates a 24-word recovery phrase. Ledger’s support documentation says accounts generated by a Ledger device can be recovered on any hardware or software wallet that supports the same standards as Ledger (BIP32, BIP39 and BIP44); every account appears only if that wallet supports the same coins and derivation paths. Ledger says all its devices offer a passphrase, which opens a separate set of accounts and cannot be recovered if forgotten. Ledger’s pages we checked do not state native SLIP-39 support.

Ledger Recover, a paid optional subscription that Ledger names as available for the Nano X, stores an encrypted copy of the seed split between three companies, released after identity checks. Ledger documents Bitcoin multisig through its Bitcoin app and coordinator software. See our seed phrase guide.

What crypto does the Ledger Nano X support?

Ledger lists 500+ coins through its Ledger Wallet app and thousands more through third-party wallets. We found no Bitcoin-only edition.

How much does the Ledger Nano X cost?

It was listed at $99 on Ledger’s online shop on 14 October 2026. On the same date the Nano S Plus was listed at $69 and the Nano Gen5 at $179. These are dated snapshots.

What other security events involve the Nano X?

Our record holds three more model-level events:

• 17 May 2021: Ledger disclosed a length-extension attack in its device-to-server secure channel, rated limited in impact and fixed in Nano X firmware 1.3.0.
• 22 June 2021: after a user on the Ledger subreddit reported receiving an unsolicited “replacement” Nano X, Kraken rebuilt the attack on a Nano X it ordered online: a hidden USB drive inside the device carried a fake app meant to phish the seed. Kraken said the Ledger wallet and firmware had no flaw.
• 10 January 2025: a firmware-update validation flaw could permanently brick a device; fixed in Nano X 2.4.2. Ledger says funds were never at risk.

Brand-level events, such as the 2020 customer-data breach and the January 2026 Global-e data exposure, are listed with sources below the article.

What we could not verify

• Bitcoin-only edition: not found on the Ledger pages we checked.
• Native SLIP-39 backup: not stated on the Ledger pages we checked.
• Independent Bluetooth audit: none found; the Bluetooth claims above are Ledger’s.
• Country of manufacture: Ledger’s comparison page gives its Paris company address, not where the device is assembled.
