Hardware Wallet

A hardware wallet is a dedicated physical device that stores your private keys offline and signs transactions inside its own secure chip, so the keys never touch an internet-connected computer. You connect it by USB, Bluetooth or QR code, review the transaction details on the device screen, and confirm with a button press, which means malware on the host machine can request a signature but cannot extract the key. Hardware wallets are the most common form of cold storage for long-term holdings. They do not remove every risk: a tampered or counterfeit device, a leaked recovery phrase, or approving a malicious transaction shown on screen can still cause loss. Buy only from the manufacturer, verify the device during setup, and store the recovery phrase separately from the device itself.
