What is a hardware wallet

A hardware wallet is a small physical device that stores your crypto private keys offline, signing transactions without ever exposing those keys to an internet-connected computer. It matters because most crypto theft happens through hacked exchanges or malware on a phone or laptop, and keeping keys offline removes that entire attack surface. A reader's next question is usually how it differs from a software wallet: a hardware wallet like a Ledger Nano X or Trezor Model One requires you to physically press a button to approve each transaction, so malware can't silently drain funds. You still need to back up the recovery phrase, usually 12 or 24 words, written on paper and stored somewhere safe. Lose both the device and that phrase, and the funds are gone for good.
