How to Set Up a Ledger Nano X for Storing Bitcoin and Ethereum Offline?

Device Initialization Process

1. Power on the Ledger Nano X by pressing both side buttons simultaneously for three seconds until the welcome screen appears.

2. Connect the device to a computer via USB-C cable and open the official Ledger Live desktop application downloaded exclusively from ledger.com.

3. Within Ledger Live, select “Set up a new device” and confirm the model as Nano X.

4. Choose a PIN code consisting of four to eight digits; this PIN must be entered each time the device is powered on.

5. The device generates a 24-word recovery phrase offline—write each word in exact order on physical paper, never digitally.

6. Verify the recovery phrase by selecting words from a randomized list displayed on the device screen to confirm correct transcription.

Wallet Configuration and Asset Import

1. After initialization, Ledger Live displays the dashboard with options to “Add account” for supported blockchains.

2. Select Bitcoin (BTC) and click “Continue” to generate a native SegWit address compatible with modern transaction fee structures.

3. Repeat the process for Ethereum (ETH), ensuring the app creates an ERC-20 compliant address that supports tokens and smart contract interactions.

4. Each added account appears as a separate tile showing real-time balance, transaction history, and network status indicators.

5. No private keys ever leave the Secure Element chip; all signing operations occur inside the hardware during confirmation prompts.

Transaction Signing and Verification

1. Initiate a send action in Ledger Live by entering the recipient’s address and amount for either BTC or ETH.

2. The application transmits only unsigned transaction data to the device—no sensitive information crosses the USB interface.

3. The Nano X screen displays full details: destination address, amount, network fee, and blockchain identifier.

4. Press both side buttons to approve or reject—the signature is computed internally and sent back encrypted to Ledger Live.

5. Once signed, Ledger Live broadcasts the transaction to the respective peer-to-peer network without storing any cryptographic material.

Bluetooth Pairing and Mobile Compatibility

1. Enable Bluetooth in the Nano X settings menu using the device’s touchscreen interface.

2. Install the Ledger Live mobile app on iOS or Android and grant location permissions required for Bluetooth discovery.

3. Scan for nearby devices and pair only with the unit displaying the matching six-digit code shown on both screens.

4. Use the mobile app to view balances, receive addresses, and initiate transactions—though final approval always requires physical interaction with the hardware.

5. Disable Bluetooth when not actively managing assets to reduce potential attack surface exposure.

Security Maintenance Protocols

1. Check firmware updates regularly through Ledger Live and install them only after verifying digital signatures using GPG keys published on ledger.com.

2. Never enter the 24-word recovery phrase into any software, website, or third-party application—even if it claims to be official.

3. Store the recovery phrase in a fireproof and waterproof safe, separate from the physical device.

4. Avoid connecting the Nano X to untrusted computers or public charging stations where malware could intercept USB enumeration traffic.

5. Reinitialize the device immediately if unusual behavior occurs—such as unexpected prompts, mismatched screen text, or failure to recognize installed apps.

Frequently Asked Questions

Q1. Can I use the same Ledger Nano X for both Bitcoin and Ethereum without compromising security?Yes. The Secure Element isolates key derivation paths per blockchain, preventing cross-contamination between BTC and ETH keyspaces.

Q2. What happens if I lose my Nano X but retain the 24-word recovery phrase?You can restore full access to all assets on any Ledger device or compatible wallet by entering the phrase during setup.

Q3. Does the Nano X support staking for Ethereum after the Merge?Yes. Ledger Live enables direct ETH staking with validator selection, deposit coordination, and reward tracking—all signed offline.

Q4. Is it safe to store USDT on a Ledger Nano X?Yes. USDT on Ethereum, Tron, and other supported chains is fully manageable through Ledger Live with native token detection and balance synchronization.
