hardware wallet
Offline key keeper
A hardware wallet is a physical device that stores cryptocurrency private keys offline, protecting them from hackers and malware.
Unlike software wallets on computers or phones, hardware wallets keep sensitive data isolated: I moved my Bitcoin to a hardware wallet after the exchange hack.
Users must physically connect the device and confirm transactions, adding security through inconvenience.
