Hardware Wallets

Intermediate 6 minSelf-Custody

A hardware wallet is a physical device designed to store your Bitcoin private keys offline. It is widely considered the gold standard for Bitcoin security, especially for significant holdings. This article explains what hardware wallets are, how they work, which ones to consider, and how to use one alongside your Heartbit account.

What Is a Hardware Wallet?

A hardware wallet is a small electronic device, often resembling a USB stick or a small calculator, that generates and stores your private keys in a secure chip that never connects to the internet. When you want to send Bitcoin, the transaction is signed inside the device and only the signed transaction, not your private key, is transmitted to the network.

This means that even if your computer is infected with malware, your private keys remain safe because they never leave the hardware device.

How It Works

The process of using a hardware wallet follows these steps.

  • Initial setup: the device generates a new seed phrase, which you write down and store securely. This seed phrase is your backup.
  • Receiving: the device provides addresses where you can receive Bitcoin. You can generate and share these addresses through the companion software.
  • Sending: when you want to spend Bitcoin, the companion software creates an unsigned transaction. You connect the hardware wallet, verify the recipient and amount on the device screen, and physically press a button to sign the transaction. Only then is the signed transaction broadcast.

Popular Hardware Wallets

Several reputable manufacturers produce hardware wallets. Each has different strengths.

  • Ledger (Nano S Plus, Nano X, Stax): French company, widely used, supports many cryptocurrencies, Bluetooth option on higher models. Uses a secure element chip.
  • Trezor (Model One, Model T, Safe 3): Czech company, open-source firmware, touchscreen on higher models. One of the original hardware wallet manufacturers.
  • ColdCard: Canadian company, Bitcoin-only focus, air-gapped operation possible (no USB connection needed), advanced features for power users.
  • BitKey by Block (formerly Square): designed for simplicity, mobile-first design, built-in fingerprint reader. Backed by Jack Dorsey's company.

For most users, any of the first three options is a solid choice. Start with whichever feels most approachable. The best hardware wallet is the one you actually use correctly.

Sending Bitcoin from Heartbit to Your Hardware Wallet

Once your hardware wallet is set up, transferring Bitcoin from Heartbit is straightforward.

  • Open your hardware wallet's companion software and navigate to the Receive section. Copy your Bitcoin address.
  • On Heartbit, go to your Wallet and select Withdraw.
  • Paste the address from your hardware wallet. Double-check it matches exactly.
  • Enter the amount. Consider starting with a small test amount for your first transfer.
  • Confirm the withdrawal. Heartbit will broadcast the transaction to the Bitcoin network.
  • Wait for confirmations. Your hardware wallet's companion software will show the incoming transaction.

Best Practices

  • Buy only from official manufacturers or authorized resellers. Never buy a used hardware wallet or one from an unverified seller. Tampered devices can steal your funds.
  • Set a strong PIN. The PIN protects against physical theft. Without it, someone who steals your device cannot access it.
  • Store your seed phrase separately from the device. If both are in the same location and that location is compromised, you lose everything.
  • Keep the firmware updated. Manufacturers release security updates regularly. Always update through the official companion software.
  • Test your backup. After setting up, reset the device and restore from your seed phrase once. This confirms your backup is correct before you store significant value on it.

When a Hardware Wallet Makes Sense

A hardware wallet is recommended when you are holding an amount of Bitcoin that you would be seriously distressed to lose. There is no specific threshold, as it depends on your personal financial situation, but many people adopt hardware wallets once their holdings exceed a few hundred dollars equivalent.

For day-to-day trading and smaller amounts, keeping Bitcoin on Heartbit is perfectly reasonable. Heartbit's infrastructure is regulated and secured. Think of it like keeping spending money in your regular wallet and savings in a safe. Both have their place.
