This nano x guide explains how to use Ledger Nano X with a focus on Bluetooth, mobile usage, and the security trade-offs you should weigh before putting large long-term holdings on a hardware wallet. I’ve been testing hardware wallets since 2018, and in my experience the Nano X is designed for users who prioritize mobile convenience (phone-first workflows) while still wanting non-custodial self-custody.
Expect clear step-by-step setup instructions, security architecture explained in plain language, and practical tips for daily use. If you want foundational reading on seed phrases and passphrases, see the BIP-39 specification for the recovery phrase standard BIP-39.

How to use Ledger Nano X for the first time (short checklist):
For a full setup walkthrough, consult our general setup guide and the dedicated restore & recovery page.
What I've found: most mistakes on day one come from rushing the seed phrase step. Slow down. And double‑check each word as you write it down.
The Nano X adds Bluetooth Low Energy (BLE) to let you sign transactions from a phone without a cable. Bluetooth is a transport only; private keys are held in the secure element and signing requires physical confirmation on the device screen.
How pairing works (short): your phone uses the companion app to detect the device, the hardware wallet requests a pairing confirmation, and an encrypted channel is established. The Bluetooth Special Interest Group maintains the BLE security model; you can read their security overview at the Bluetooth SIG site Bluetooth security overview.
Trade-offs to consider:
Is Bluetooth safe? It depends on your threat model. For large holdings I prefer offline or multisig strategies. For everyday use I use Bluetooth but only with an up-to-date phone and never with background apps allowed to access BLE.

But if you want maximal isolation, consider air-gapped signing workflows detailed on our air-gapped page.
The core protections are:
These points are not theoretical. In practice, the secure element and manual confirmation are the last line of defense when phones or PCs are compromised.
References: general hardware wallet principles and transaction signing are discussed in Bitcoin standards like PSBT BIP-174.
Decisions here determine long-term recoverability.
I believe most users are best served by a single, carefully-stored 24-word seed phrase and a metal backup kept in a separate secure location. And remember: never store the seed phrase digitally.
Multisig (multiple signatures required to spend) raises the bar against single‑point failures. Use multisig when you want geographic distribution of keys, corporate custody, or inheritance planning.
Key points:
What I've found: for large holdings, a 2-of-3 multisig spread across a hardware wallet, a second hardware wallet stored elsewhere, and a secure offline key gives a good balance of redundancy and security.
See ledger-live for account management, and add-accounts-apps for installing blockchain apps on the device.
Common mistakes I see: buying from unofficial sellers, taking a photo of the recovery phrase, skipping firmware verification, and using passphrases without documenting backup procedures.
If the device breaks you can recover with your seed phrase (see restore & recovery). If the vendor stops operating, you still control funds as long as you hold the seed phrase — this is one advantage of non-custodial self-custody. For buying safely, read where to buy safely.

Q: Can I recover my crypto if the device breaks? A: Yes — recover using your seed phrase on a compatible hardware wallet or software that supports the same derivation method. See restore & recovery.
Q: What happens if the company goes bankrupt? A: Your crypto remains accessible as long as you control the seed phrase. The device maker going out of business does not erase your keys, but you should maintain backups and exportable recovery details.
Q: Is Bluetooth safe for a hardware wallet? A: Bluetooth is a convenience trade-off. Safe for many users if you verify transactions on-device and keep the phone secure. For very large holdings consider USB-only or multisig approaches.
Bluetooth and mobile support make the device easy to use on phones, but they also expand your attack surface. In my testing, the convenience is worth it for everyday use — provided you follow strict backup and verification practices. If you want step-by-step setup or to compare models, start with our setup guide and review firmware updates before linking the device to any account.
