# Hardware wallets

A hardware wallet stores your Bitcoin keys and signs transactions inside a dedicated device, so malware on your computer can't steal them. Learn how to use one.

## A safe for your keys
A hardware wallet (or "signing device") generates your [seed](https://mybitcoinexplorer.com/learn/seed-phrases-bip39) inside itself and never lets the private keys out. Your computer can ask it to sign, but can't read the keys.

## Why the screen matters
Malware on your computer could swap the destination address. The hardware wallet's own screen shows what you're actually signing. **Always check the address and amount on the device**, not just on your computer.

## Choosing and using one
- Buy directly from the manufacturer or an authorised seller.
- Set it up yourself: it should generate a new seed. Never accept a device with a seed already written for you.
- Write down the seed offline and keep it safe. The device can be replaced; the seed can't.
- Consider open-source firmware and devices that work with your own node.
- Optionally add a [passphrase](https://mybitcoinexplorer.com/learn/seed-passphrase).

## What it doesn't protect against
- Someone finding your seed backup.
- You approving a transaction you didn't check.
- Physical coercion. [Multisig](https://mybitcoinexplorer.com/learn/multisig) and good habits help here.


## Setting one up safely
1. Unbox and check the packaging for tampering.
1. Update the firmware from the manufacturer's official software.
1. Generate a new seed on the device and write it down offline.
1. Confirm the seed when the device asks.
1. Send a small test, then test a restore before storing large amounts.

## Bitcoin-only firmware
Some devices offer Bitcoin-only firmware with less code, which reduces the attack surface for people who don't need other coins.


## Key takeaways

- Hardware wallets keep keys inside a dedicated device.
- Always verify the address and amount on the device screen.
- Your seed backup is what really holds the funds.

## Common questions

### What if my hardware wallet breaks?

Restore your seed on a new device or compatible wallet. Your coins are on the blockchain, not on the device.

### Can a hardware wallet be hacked?

Some attacks need physical access and skill. A passphrase and good backups reduce the risk.

### Do I need a hardware wallet?

For small amounts a phone wallet is fine. For savings you couldn't afford to lose, a hardware wallet is strongly recommended.

### What if the hardware wallet company disappears?

Your seed phrase works in other compatible wallets, so your bitcoin isn't tied to one company.
