Hardware Wallet
A dedicated physical device that stores private keys offline and signs transactions internally.
A hardware wallet is a small dedicated device built to hold private keys offline and to sign transactions without ever exposing those keys to a connected computer. When you approve a payment, the transaction is sent to the device, signed inside it, and returned, so the secret key never leaves the hardware even if the attached computer is infected. This makes hardware wallets a popular and practical form of cold storage. To stay safe, a hardware wallet must be bought from the official manufacturer or an authorised seller and initialised by the user so it generates a fresh seed phrase during setup. A device that arrives with a pre-printed seed phrase should never be trusted.
