Bitcoin with Nano X — Wallets, Addresses & Best Practices

Quick summary

This guide explains practical Bitcoin usage with the Ledger Nano X bitcoin wallet: how Bitcoin addresses and multiple wallets work on the device, how to use Electrum with it, safe ways to sweep a paper wallet, and best practices for seed phrases and passphrases. I’ve tested this style of workflow since the 2017–2018 cycle and watched common mistakes first-hand. What I’ve found: the device is convenient for mobile use, but convenience brings trade-offs (more on that below).

How Bitcoin lives on a hardware wallet

A hardware wallet doesn’t hold your coins. It holds the private keys that sign transactions. The wallet generates those private keys from a seed phrase using BIP-39 and a hierarchical derivation scheme (BIP-32 with BIP-44/BIP-84 paths for Bitcoin). Short version: one seed phrase can generate many addresses. Simple.

Why create multiple wallets (accounts) on one device? For separation of funds. Use one for day-to-day spending, another for long-term savings, and a third for test transactions. It keeps bookkeeping easy and limits blast radius if you make a mistake.

(Yes, you can have many — but plan recovery and naming carefully.)

Useful reading: setup steps are covered in detail on the first-time setup and nano-x-setup pages.

Step-by-step: Setup & create multiple Bitcoin wallets

How to add Bitcoin accounts (high-level). These steps use the device plus a desktop or mobile wallet that supports hardware wallets.

Power on and unlock the device with your PIN. Install the Bitcoin app on the device via the official companion app (follow the device prompts).
In your wallet software (companion app or Electrum), choose Add Account → Bitcoin. The wallet will read the device-derived xpub and create an account.
To create more wallets: repeat Add Account. Each new account uses a separate account index (a separate set of addresses).
To receive funds: choose Receive in the wallet. Always verify the address shown on your device screen before sharing it. The device will display the address and require a physical button press to confirm. Don’t skip that.

Tip: label accounts clearly (spend / savings / escrow). That’s saved time during audits.

Quick example: why separate accounts?

Savings account: cold, low-activity.
Spending account: regular, track small purchases.
Exchange funding account: temporary, wiped after transfer.

You can move between them with a signed transaction and keep records in your wallet software.

Using Electrum and sweeping a paper wallet

Electrum is commonly used with hardware wallets for advanced Bitcoin features such as custom fee setting, multisig, and sweeping legacy paper wallets.

Sweeping a paper wallet to the device (safe approach):

Create a fresh receive address on your hardware wallet. Confirm it on-device.
In Electrum, use the Sweep feature: enter the paper private key and sweep funds directly to the hardware-derived receive address. Electrum will build and broadcast a transaction.

Warning: sweeping requires entering a private key into software. That exposes the key to the computer. If you value maximum safety, make the transaction with an air-gapped signing flow (create the PSBT on an offline machine, sign, then broadcast from an online machine). Electrum supports PSBTs and hardware signing.

Seed phrase, passphrase (25th word) and backups

12 vs 24 words: what changes? A 12-word seed phrase gives 128 bits of entropy; 24 words give 256 bits. More entropy means higher brute-force resistance, but both are currently strong. I believe 12 words are fine for many users; 24 words add margin if you’re worried about future advances.

Passphrase (the so-called 25th word) creates a hidden wallet on top of the seed phrase. It’s effectively a separate factor. Use it only if you can store and remember it securely. Why? If you forget the passphrase you lose access to funds forever. And passphrases can make inheritance planning harder.

Metal backup plates are worth the small extra effort. They survive fire, water, and time. Consider geographic distribution for redundancy (don’t store everything in one safe). For advanced secret-sharing, look into SLIP-39/Shamir backups — they split the seed into shares that can be distributed.

Multisig options for stronger protection

Why multisig? It removes single points of failure. Instead of one device holding a private key, N-of-M signers are required to move funds. That could be 2-of-3 signers across devices and locations.

How to use it with this device: pair the hardware wallet as one signer with compatible desktop wallets (Electrum, Sparrow, Caravan). The device will hold one of the keys and will only sign when you physically confirm on-device.

Pros: better resilience and shared custody.
Cons: more setup complexity, longer recovery steps, and the need to coordinate signers (especially for inheritance).

See the multisig-bitcoin-setup guide for a full walkthrough.

Connectivity, firmware & supply-chain checks

Bluetooth vs USB? Bluetooth is convenient for mobile use. But it adds an attack surface for the host device. The hardware wallet keeps private keys isolated inside the secure element and requires on-device confirmations, which limits risk. Still, if you want absolute minimal exposure, use USB-only or an air-gapped PSBT workflow.

Firmware updates matter. They patch bugs and add features. Always update firmware through the official path and verify the device prompts you to confirm the update. If you see unexpected messages during first setup, pause and check the authenticity / supply chain checklist.

For step-by-step update instructions see how-to-update-firmware-steps and firmware-update.

Common mistakes & quick security checklist

Buying from unofficial sellers (tampering risk). See where-to-buy-safely.
Storing seed phrase digitally (screenshots, cloud notes). Don’t.
Using a passphrase without a recovery plan. Dangerous.
Sweeping paper wallets on a compromised machine. Use PSBTs or air-gapped signing.

Quick checklist before sending large amounts:

Confirm receive address on-device.
Verify firmware is up to date.
Use a known, clean computer for any private-key entry (ideally avoid it).

FAQ

Q: Can I recover my crypto if the device breaks?
A: Yes. Recover funds with your seed phrase on a compatible hardware wallet (or recovery tool that supports BIP-39). Keep your seed phrase safe. See recover-if-broken.

Q: What happens if the company behind the device goes bankrupt?
A: Your funds remain recoverable so long as you have your seed phrase and compatible recovery options. The device maker going under does not erase your private keys. See company-bankrupt for scenarios.

Q: Is Bluetooth safe for a hardware wallet?
A: Bluetooth is safe if you follow best practices: update firmware, confirm addresses on-device, and avoid untrusted networks. For maximum assurance, use wired or air-gapped workflows.

Conclusion & next steps

Using Bitcoin with the Nano X bitcoin wallet gives a good balance of mobile convenience and hardware-level protection. But convenience comes with trade-offs. In my testing, the device made everyday transactions smooth while still forcing on-device confirmations for safety. That said, consider multisig for larger sums and prefer metal backups for long-term storage.

Ready to go deeper? Start with the nano-x-setup guide and read the multisig-bitcoin-setup walkthrough if you plan to split keys. If you’re moving coins from a paper wallet, follow the Electrum guidance on wallet integration and sweep only after reviewing the security notes above.

And remember: no single solution fits everyone. Plan your recovery, test small transfers, and document your decisions for those who might need them later.
