A Ledger wallet is a hardware wallet designed for secure cryptocurrency storage and transactions. Unlike software wallets, which store private keys on internet-connected devices, Ledger wallets store private keys offline in a secure hardware device, making them resistant to hacking and online attacks. 

Ledger wallets support a wide range of cryptocurrencies, including Bitcoin, Ethereum, Litecoin, and many others. They use a secure element chip to store private keys and execute cryptographic operations, adding an extra layer of protection.

To use a Ledger wallet, users connect it to their computer or mobile device via USB or Bluetooth and interact with it using companion software applications. Transactions are verified and signed directly on the device, ensuring that private keys never leave the secure environment of the hardware wallet.

Ledger wallets also come with backup and recovery options, allowing users to recover their funds in case the device is lost or damaged. Additionally, they feature PIN protection and passphrase support to further enhance security.

Overall, Ledger wallets offer a convenient and secure way for cryptocurrency holders to store and manage their digital assets, providing peace of mind knowing that their funds are safe from online threats.
