Ledger wallets are hardware cryptocurrency wallets made by Ledger, a company headquartered in Paris, France.
Ledger’s hardware wallets are multi-currency wallets that are used to store private keys for cryptocurrencies offline. A hardware wallet is a cryptocurrency wallet that stores the user’s private keys in a secure hardware device.
The main principle behind a hardware wallet (also known as a cold wallet) is to provide full isolation between the private keys and your easy to hack computer or smartphone.
