A type of cryptocurrency wallet that's based on a physical device, such as a USB thumb drive with buttons and a screen, that stores your private keys to your cryptocurrency funds. A hardware wallet is considered a cold wallet in that it isn't connected to the Internet, keeping your wallet (and wallet funds) away from hackers and theft.
Example
“After the exchange hack, the trader moved all their Bitcoin to a Ledger Nano X hardware wallet to keep their private keys offline and secure.”
