Ledger Nano X
The Ledger Nano X adds Bluetooth 5.0 and a 100mAh battery to Ledger's proven CC EAL6+ secure element platform, enabling wireless transaction signing from mobile phones via the Ledger Live app. It is the most popular Ledger device, balancing security with the convenience of mobile crypto management.
Best hardware wallet for mobile crypto management, skip if you prefer USB-only security or want a touchscreen.
Where to Buy
Pros
- Bluetooth 5.0 enables mobile signing via Ledger Live on iOS and Android
- Same CC EAL6+ secure element (ST33K1M5) as all Ledger devices
- 100mAh battery for 8 hours of wireless operation
- 5,500+ supported cryptocurrencies across 50+ blockchains
- USB-C for desktop use when Bluetooth is not desired
Cons
- Bluetooth adds a theoretical wireless attack surface (mitigated by secure element)
- 128x64 OLED display is small for verifying transaction details
- Two physical buttons — no touchscreen like the Flex or Trezor Safe 5
- Battery degrades over time — eventually requires USB-C for all use
Mobile Signing via Bluetooth
The Nano X's Bluetooth 5.0 connection to the Ledger Live mobile app is its primary differentiator. You can check balances, initiate transactions, and approve them by pressing the physical buttons on the Nano X — all without a USB cable. The secure element ensures that private keys never leave the device over Bluetooth; only signed transactions are transmitted.
Ledger's Bluetooth implementation uses encrypted pairing with the Ledger Live app. The secure element handles cryptographic operations independently of the Bluetooth channel. Even if the Bluetooth connection were compromised, an attacker would see only signed transaction data — they cannot extract private keys or forge signatures.
Nano X vs Nano S Plus vs Flex
The three current Ledger devices share the same ST33K1M5 secure element and support the same 5,500+ assets. The differences are interface and connectivity: the Nano S Plus is USB-only at the lowest price. The Nano X adds Bluetooth and battery at mid-range price. The Flex adds a 2.84-inch E-Ink touchscreen, Bluetooth 5.2, NFC, and a card-sized form factor at premium price.
For most users, the Nano X hits the sweet spot — mobile signing capability without the premium of the Flex's touchscreen. The Nano S Plus is the rational budget choice for desktop-only users.

Who Should Buy This
Bluetooth for phone signing, USB-C for laptop. Ledger Live works on both platforms with the same device. 8-hour battery covers a day of mobile use.
The Nano S Plus does the same job for less money. If you only plug in once a month to check balances, Bluetooth adds cost without benefit.
Better alternative: Ledger Nano S Plus
The Ledger Flex has a 2.84-inch E-Ink touchscreen, Bluetooth 5.2, and NFC for a premium experience. If budget allows, the Flex is the better device.

Frequently Asked Questions
Is Bluetooth on the Nano X a security risk?
The risk is minimal. Private keys never leave the secure element. Bluetooth transmits only signed transactions and public data. The secure element performs all cryptographic operations independently. However, if you want zero wireless attack surface, the Nano S Plus is USB-only.
How long does the Nano X battery last?
Approximately 8 hours of active Bluetooth use. Standby time is several weeks. The battery charges via USB-C. Over time (2-3 years), battery capacity degrades but the device always works via USB-C.
Can the Nano X connect to iPhone?
Yes, via Bluetooth. Ledger Live for iOS supports the Nano X over Bluetooth. The Nano S Plus cannot connect to iPhones as it requires USB-C and iOS does not support USB-C OTG for Ledger.
Ledger Nano X vs Trezor Safe 3: which is better?
The Nano X has Bluetooth for mobile use. The Trezor Safe 3 is USB-only but has fully open-source firmware and supports 9,000+ coins (vs 5,500+). Choose the Nano X for mobile signing; choose the Trezor for open-source verification and broader coin support.
Can I use the Nano X without Bluetooth?
Yes. It works exactly like the Nano S Plus via USB-C. You can disable Bluetooth in settings if you want USB-only operation. Many users keep Bluetooth off by default and enable it only for mobile sessions.
