Ledger ?
What is a ledger and what its utility ?
Ledger wallets are hardware cryptocurrency wallets made by Ledger, a company headquartered in Paris, France 🇫🇷. In the U.S., the company has offices in San Francisco, California. Ledger was launched in 2014 by eight experts who had backgrounds in embedded security, cryptocurrencies, and entrepreneurship. The company's goal is to create secure solutions for blockchain applications. Ledger's hardware wallets are multicurrency wallets that are used to store private keys for cryptocurrencies offline. Conducting transactions using cryptocurrencies requires the use of cryptographic private keys. But these keys, which are generally stored online, are susceptible to theft and hacks. Cryptocurrency users have developed alternative systems for storage. These include hot wallets (which are online), mobile wallets (wallets on smartphones), and paper wallets (stored on paper).
Hardware wallets are a form of offline storage. A hardware wallet is a cryptocurrency wallet that stores the user's private keys (a critical piece of information used to authorize outgoing transactions on the blockchain network) in a secure hardware device.
Ledger's hardware wallets are device-based, which means they use storage mechanisms—USB drives—to store private keys, thereby making it difficult for hackers to access the key from an online location. Ledger offers two hardware wallets: the Ledger Nano S and the Ledger Nano X wallets. Ledger official website:
How to set up your ledger for Solana:
When it comes to Ledgers I recommend buying directly from the Ledger company and to buy one using their official site, buying off third-party sellers is less safe and you don't want to receive your ledger already infected.
