A hardware wallet is a physical device designed to securely store cryptocurrency private keys offline. Unlike software wallets, which are connected to the internet and can be vulnerable to hacking, hardware wallets provide an extra layer of security by keeping your keys in a safe environment. This makes them a popular choice for individuals looking to protect their digital assets. These wallets typically connect to a computer or mobile device via USB or Bluetooth, allowing users to manage their cryptocurrencies easily. Well-known examples of hardware wallets include Ledger and Trezor, which offer user-friendly interfaces and robust security features to safeguard your investments.
