How to use a hardware wallet with BlueWallet? (Bitcoin-Only Guide)

Connecting Your Hardware Wallet to BlueWallet

1. Ensure your hardware wallet supports Bitcoin-only mode and is compatible with BlueWallet — Ledger Nano S/X and Trezor Model T are officially supported.

2. Install the latest firmware on your device using the manufacturer’s desktop application before connecting to BlueWallet.

3. Enable Bitcoin app on Ledger devices or Bitcoin Core on Trezor via their respective manager interfaces.

4. Connect the hardware wallet to your mobile device using a USB-OTG adapter for Android or a Lightning-to-USB 3 camera adapter for iOS.

5. Open BlueWallet, tap the '+' icon in the wallet list screen, then select “Hardware Wallet” and follow the on-screen prompts.

Setting Up a Bitcoin-Only Wallet Instance

1. During setup, BlueWallet will detect your connected device and request permission to access its Bitcoin derivation paths.

2. Choose “Bitcoin (mainnet)” explicitly — avoid selecting testnet or other coin options even if listed.

3. Confirm the wallet name, e.g., “My Ledger BTC”, and allow BlueWallet to scan for existing Bitcoin addresses.

4. Verify the first receiving address matches what appears on your hardware wallet’s display screen before proceeding.

5. BlueWallet will generate a watch-only wallet; all private keys remain fully isolated inside the hardware device.

Receiving Bitcoin Securely

1. Tap the newly created hardware wallet in BlueWallet and select “Receive”.

2. A QR code and Bitcoin address will appear — both are derived from your hardware wallet’s BIP84 (bech32) path by default.

3. **Never share your device’s seed phrase or export extended public keys outside trusted environments.

4. The hardware wallet must be unlocked and on the Bitcoin app screen when generating new receive addresses.

5. Each time you tap “New Address”, BlueWallet communicates with the device to derive and display the next unused address.

Sending Bitcoin with On-Device Confirmation

1. Tap “Send”, enter the recipient’s Bitcoin address and amount, then confirm transaction details in BlueWallet.

2. BlueWallet prepares the unsigned transaction and forwards it to your hardware wallet via the connected interface.

3. **Your hardware wallet must display the full recipient address, amount, and fee — verify every character before approving.

4. Press the physical button on your device to sign the transaction — no signature leaves the hardware wallet.

5. BlueWallet broadcasts the signed transaction to the Bitcoin network once confirmation is received from the device.

Troubleshooting Common Connection Issues

1. If BlueWallet fails to detect your device, restart the mobile app and re-plug the hardware wallet while it’s unlocked and on the Bitcoin app.

2. Android users may need to disable battery optimization for BlueWallet to maintain stable USB communication.

3. iOS users must ensure the Lightning adapter supports data transfer — some charging-only adapters block communication.

4. Firmware mismatch errors require updating both the hardware wallet and BlueWallet to their latest versions simultaneously.

5. **Do not attempt to use Bluetooth or wireless pairing — BlueWallet only supports wired hardware wallet connections for Bitcoin.

Frequently Asked Questions

Q: Can I import a Ledger or Trezor wallet into BlueWallet without the physical device?A: No. BlueWallet requires the physical hardware wallet to be present and unlocked for every operation — no seed import or software backup is allowed.

Q: Does BlueWallet support multisig setups with hardware wallets?A: Not in Bitcoin-only mode. Multisig functionality in BlueWallet is limited to software-based wallets and does not integrate with hardware signing for Bitcoin.

Q: Why does BlueWallet show zero balance after connecting my Trezor?A: This usually occurs when the Trezor is not running the Bitcoin app or when the device is locked. Unlock it, open the Bitcoin app, and refresh the wallet in BlueWallet.

Q: Can I use the same hardware wallet with BlueWallet and another app simultaneously?A: Yes, but only one app can communicate with the device at a time. Close other wallet apps before launching BlueWallet to prevent connection conflicts.
