Ledger Wallet is a hardware wallet designed to keep your cryptocurrencies safe offline. For the most part, online wallets are relatively safe, but the potential for hackers or malware to gain access to your most sensitive data always exists. Ledger solves major security issues by providing a trust layer between the blockchain system and the physical world: security devices to keep private keys out of reach of hackers and ensure a proof of presence of the user to mitigate man in the middle attacks. For holding cryptocurrencies long term, Ledger Wallet is the ultimate in offline, cold storage, wallet security.
Ledger makes a suite of products designed to make storage and security easy. For around $60, their most popular product is the Nano Ledger S. With Ledger Nano S, secrets like private keys are never exposed: sensitive operations are isolated inside your hardware wallet within a state-of-the-art Secure Element, locked by a PIN code. Transactions can’t get tampered with, they are physically verified on the embedded screen with a simple press on a button. Ledger Nano S includes Bitcoin, Litecoin, Ethereum and Ethereum Classic companion apps, and other blockchain-based cryptocurrencies. You can send and receive payments, check your accounts and manage multiple addresses for each currency from the same device. Nano S also supports the FIDO® Universal Second Factor standard that simplifies the authentication process on compatible online services such as GMail, Dashlane, Dropbox or GitHub.
