This Ledger Nano X review examines mobile use, Bluetooth trade-offs, and the device's security model from hands-on testing. I have been using multiple hardware wallets since the 2017 cycle, and I tested the Nano X over several months with both iOS and Android phones. Short version: it makes mobile signing far easier, but Bluetooth introduces decisions you need to understand. Want a step-by-step setup? See the setup guide.
Out of the box the unit feels solid. The metal-and-plastic build gives a reassuring heft. The screen is larger than entry-level models, which makes PIN entry and app navigation less fiddly. I liked that the recovery phrase is generated and shown on the device itself (not on a connected phone). That practice reduces early attack windows.
But packaging can be tampered with. Always inspect seals and initiate the recovery phrase creation on the device, never type it into a phone or PC.
How do you get started? The setup flow is straightforward: power on, set a PIN, and write down the recovery phrase displayed on-screen. In my experience the biggest stumbling block for new users is understanding app capacity (how many coin apps you can install) and pairing with mobile wallets.

Is Ledger Nano X Bluetooth safe? That’s the question I get most often. Short answer: Bluetooth enables useful mobile workflows. Longer answer: it expands the attack surface and requires different mitigations.
Bluetooth pros:
Bluetooth cons:
What I've found: pairing must be treated like key exchange. Confirm pairing codes on the device screen, disable Bluetooth when not in use, and prefer an OTG USB connection for high-value transfers (or when you suspect a risk). And yes, Bluetooth is convenient. But use it with intent.
For deeper technical comparisons of connection methods see bluetooth-usb-nfc-security and connectivity-bluetooth-otg.
A hardware wallet like the Nano X protects private keys by isolating signing operations. The critical components to understand are:
In my testing I paid attention to what is displayed on the device before accepting a transaction. Small screens can hide details, but the Nano X’s screen is large enough that the majority of transactions show useful information. For more on the architecture see security-architecture and verify-authenticity.
Seed phrase basics: you get a 24-word recovery phrase by default (some models offer 12; check your model). This recovery phrase is the master key to your funds. Treat it like the master key to a safe deposit box. In my setups I always use a metal backup plate for long-term durability.
Passphrase (25th word): adding a passphrase creates a hidden account derived from the recovery phrase plus that extra word. It can give plausible deniability or extra security, but it introduces a critical risk: if you forget the passphrase, you lose access permanently. What I recommend: treat passphrases as a form of secret key management and store them with equal care. For detailed strategies see passphrase-25th-word-guide and seed-phrase-management.
Shamir-style backups (SLIP-39) are an option on some ecosystems; if you plan to split backups among family or geographic locations, learn the trade-offs (complexity vs redundancy).
Multi-signature (multisig) setups increase resilience: a multisig wallet spreads signing authority across multiple hardware wallets or devices. That protects you from single-point failures (device loss, theft) and insider risk.
I ran a 2-of-3 multisig test using one Nano X plus two other devices. The workflow added complexity, but the security improvement for long-term holdings is meaningful. If you hold large bitcoin positions, multisig is worth considering. Read the multisig primer here: multisig-for-ledger.
Supported networks: the device supports Bitcoin, Ethereum, many EVM tokens, and other blockchains such as Solana and Cardano through third-party wallets. For specifics see supported-coins-networks, ledger-and-bitcoin, ledger-and-ethereum-defi, and ledger-and-solana-nfts.
| Feature | Nano X | Nano S Plus | Nano S |
|---|---|---|---|
| Bluetooth | Yes | No | No |
| Battery | Rechargeable | No | No |
| App capacity | Larger | Moderate | Limited |
| Screen size | Larger | Medium | Small |
| Secure element | Yes | Yes | Yes |
This table is factual-feature focused, not a ranking. Each model has trade-offs: Bluetooth and battery increase convenience but add considerations for threat modeling.
Who this device is best for: mobile users who need frequent on-the-go signing and want higher app capacity. Who should look elsewhere: people who prefer strictly air-gapped workflows or minimal attack surface (consider non-Bluetooth models). For more comparisons see ledger-model-comparison.
Firmware updates patch vulnerabilities and add features. That makes them critical. Always verify updates via official channels and confirm device prompts. In my testing I applied a few updates; the device required confirmation on-screen and a companion app message. If you skip updates you run a higher risk of relying on outdated protections. See firmware-update-guide for step-by-step instructions.
Q: Can I recover my crypto if the device breaks?
A: Yes — with the recovery phrase you can restore funds to another compatible hardware wallet or software wallet that supports the same derivation scheme. Practice a restore on a secondary device (with small test amounts) so you’re comfortable. See restore-recovery-phrase.
Q: What happens if the company goes bankrupt?
A: Your assets are secured by the recovery phrase and the blockchain. Company insolvency doesn’t destroy your keys. That said, rely on open standards and exportable recovery methods, and read company-bankruptcy-what-happens for scenarios.
Q: Is Bluetooth safe for a hardware wallet?
A: It can be, when paired responsibly and used alongside device confirmations and firmware verification. But if you want absolute minimal exposure, use wired or air-gapped alternatives. More at bluetooth-usb-nfc-security.
Common mistakes: buying from unofficial sellers, photographing your recovery phrase, and skipping firmware updates.
After months of daily testing I view the Nano X as a capable mobile-first hardware wallet that trades a slightly larger attack surface for convenience. If you value mobility and app capacity, it fits well. If your priority is absolute minimal connectivity, choose a model without Bluetooth and consider multisig for high-value holdings.
Want practical next steps? Read the setup guide and the firmware update guide, then practice a restore on a spare device. What I've found: practicing the recovery process once removes a lot of future anxiety.
