What is a hardware wallet?

A hardware wallet, also referred to as a signing device, is a physical storage device designed to generate and store public and private keys offline, as well as sign transactions.

Despite lacking some of the functionality of other wallet types, it offers improved security and simplicity for a minimal attack surface. It functions as an external device when working with other wallet types, creating and storing keys, and Bitcoin addresses for receiving and signing transactions for spending. The software on the other wallet types handles all other tasks.
