How to use a hardware wallet? (Cold storage)

Setting Up Your Hardware Wallet

1. Unbox the device and verify its authenticity using the manufacturer’s verification tool or checksum file.

2. Connect the hardware wallet to a computer or mobile device via USB or Bluetooth, depending on model specifications.
3. Install the official companion application provided by the wallet maker—never use third-party apps.
4. Initialize the device by following on-screen prompts to generate a new recovery seed phrase.
5. Write down the 12- or 24-word seed phrase on the included metal backup card or paper—do not store it digitally.
6. Confirm the seed phrase manually on the device screen to ensure correct recording.
7. Set a strong PIN code that will be required every time the device is powered on.

   Transferring Cryptocurrency to Cold Storage

   1. Open the official wallet app and select “Receive” to generate a deposit address.

8. Copy the public address carefully—verify the first and last five characters match what appears on the hardware device screen.
9. Initiate a withdrawal from your exchange or hot wallet, pasting the verified address as the destination.
10. Confirm the transaction details on the hardware wallet’s physical display before approving with button presses.
11. Wait for sufficient blockchain confirmations—typically six for Bitcoin and twelve for Ethereum—to consider funds securely stored.
12. Avoid reusing addresses; generate a new receive address for each incoming transaction to preserve privacy.

    Signing Transactions Offline

    1. In the wallet app, prepare a transaction by entering recipient address, amount, and fee parameters.

13. The app sends unsigned transaction data to the hardware wallet via secure channel.
14. Review all fields—including destination, value, and network fee—on the device’s screen before approval.
15. Physically press buttons on the device to confirm or reject the transaction.
16. Once signed, the hardware wallet returns the cryptographic signature to the app, which broadcasts it to the network.
17. No private keys ever leave the secure element inside the device during this entire process.

    Maintaining Device Security

    1. Store the hardware wallet in a physically secure location, separate from the recovery phrase backup.

18. Never enter your PIN or seed phrase on any internet-connected device or website.
19. Regularly check firmware updates through the official app and only install them after verifying digital signatures.
20. Avoid connecting the device to untrusted computers or public charging stations.
21. If the device becomes damaged or lost, use the written seed phrase to restore access on a new compatible device.

    Frequently Asked Questions

    Q: Can I use the same hardware wallet for multiple cryptocurrencies?A: Yes. Most modern hardware wallets support dozens of coins and tokens—including Bitcoin, Ethereum, Litecoin, Solana, and ERC-20 assets—as long as the official firmware includes their derivation paths and signing logic.

    Q: What happens if I forget my PIN?A: After several incorrect attempts, the device will wipe itself. You must restore full access using your original recovery seed phrase on a new or reset device.

    Q: Is it safe to update firmware over Wi-Fi?A: Firmware updates should only be performed via direct USB connection using the official desktop application. Wi-Fi-based updates are unsupported and pose serious compromise risks.

    Q: Do I need internet access to generate a new wallet?A: No. The hardware wallet generates cryptographically secure private keys entirely offline. Internet is only required later to broadcast signed transactions or check balances via the companion app.
