How to Set Up a Hardware Wallet for Cold Storage

Move meaningful holdings offline so a compromised computer can't drain them. Initialize a hardware wallet the safe way.

You'll need: A hardware wallet device, bought new from the manufacturer.

Steps

  1. Buy the device direct from the manufacturer or an authorized reseller — never used, never from a marketplace listing.
  2. Initialize the device and let it generate a new seed phrase on the device screen.
  3. Write the seed phrase on the card provided (or metal backup) — never type it into a computer, phone, or cloud note.
  4. Set a strong device PIN.
  5. Install the vendor's companion app and pair the device.
  6. Send a small test amount first, confirm receipt, then move the rest.
  7. Store the seed backup somewhere secure and offline, separate from the device.
Watch outAnyone who sees your seed phrase owns the funds. A hardware wallet bought second-hand or 'pre-initialized' may already be compromised — always generate a fresh seed on-device.
