What Is a Hardware Wallet?

A hardware wallet is a small device that holds your key and signs transactions inside the device. This page explains what that protects, and the part it cannot protect: the decision you approve on its screen.

Who this is for

People holding BTG they do not plan to spend soon, and anyone told to "get a hardware wallet" without an explanation of what it changes.

What it is

A hardware wallet generates the key inside the device and is designed never to export it. When you send BTG, your computer or phone builds the transaction and sends it to the device. The device decodes the details and shows the recipient, amount, and fee on its own screen.

You confirm with a button press. The device returns a signature, and the online app broadcasts the transaction. The key stays inside the device the whole time, so malware on the computer has nothing to read and nothing to sign with.

A clipboard hijacker can still alter the address your computer displays; it cannot alter what the device screen shows. Comparing the two is how you catch it. The limit matters too: the device has no idea whether the recipient belongs to the person you think, or whether the contract you are interacting with is honest.

Bitgold support is not documented

Whether a particular hardware wallet can be configured for Bitgold is not documented, and support varies by product. The signing model here does not change with the network.

Why it matters

The device removes the key from the machine that browses the web, reads email, and runs extensions. That is the largest reduction in remote-theft risk available. A stolen key file or a malicious browser extension gains nothing when the key is not there.

It also relocates trust. You are now trusting the device screen and your habit of reading it. A phishing page can ask you to "verify" or "sync" your wallet and walk you through typing the recovery phrase into a form; the device cannot save you.

Buy from an official source, generate the wallet yourself, set your own PIN, and keep the recovery phrase on paper. A device that arrives already initialized is a device someone else may hold the key for.

Common misunderstandings

  • "The device stores my BTG." It stores keys. The BTG balance lives on the chain, and the device only signs transactions that move it.
  • "A hardware wallet cannot be phished." The device signs what you approve. Phishing targets the approval, not the key extraction.
  • "The screen shows the address, so I do not need to check it." The screen is the source of truth only if you compare it with the recipient you intended to pay.
  • "A used device is fine once it is reset." A device can be shipped with a phrase the seller knows. Generate a new wallet yourself.

Key takeaways

  • Signing happens inside the device; the key is never handed to the computer.
  • The device screen is the trustworthy display, so verify the full address there.
  • The device cannot tell you whether the recipient or contract is honest.
  • Phishing that captures your recovery phrase bypasses the device entirely.
