The Ledger hardware wallet is a compact and portable device that looks like a flash drive. Its main purpose is the secure storage of various cryptocurrencies such as Bitcoin, altcoins, tokens and NFT. The device can be connected to a computer or smartphone via USB or Bluetooth interface. Asset management, including transactions, sale, purchase and exchange, is carried out using special software provided by the manufacturer. This software also provides a high level of security for the safety of crypto savings.

The key feature of the Ledger device is that it does not store private keys or other sensitive data in plain text. Instead, it provides secure storage of private keys to access cryptocurrencies, which makes it a reliable tool for the secure management of digital assets. Ledger's official website features three main device models: Stax, Nano X and Nano S Plus. In addition, there is an older model, the Nano S, but it can only be purchased through intermediaries, since it has been discontinued from official production.

The principle of operation

Similar to a USB flash drive, the Ledger is easily connected to a personal computer or mobile device via cable or wirelessly using wireless technology. Through special software, it synchronizes the saved data with blockchain servers and displays the balance of the user's cryptocurrency wallet. The internal storage of the Ledger cold wallet provides the ability to manage approximately 20-25 accounts for various cryptocurrencies at the same time.

When performing operations with cryptocurrency, the system sends a request to the device, which the owner must confirm by entering a PIN code. If the PIN is correct, the purchase, exchange or sale operation is performed. This provides an additional layer of security and protection against unauthorized transactions.

Who will use this wallet?

A hardware wallet, also known as cold storage, is designed to securely store cryptocurrencies in the form of access keys to various crypto assets. Unlike storage on an exchange or in a software wallet (the so-called "hot" wallet), using cold storage provides a higher level of security, since it is less vulnerable to hacking and other types of attacks.

Cold storage records sensitive information, such as private keys, on a special chip. This chip is protected from external access, which makes it impossible to access the keys without damaging the device itself. In addition, the keys are additionally protected using a seed phrase (or recovery seed) and a PIN code, which further reduces the risks of unauthorized access to cryptocurrency accounts. Such measures provide the maximum level of security and protection for owners of cryptocurrency assets.

Safety

Ledger hardware wallet is based on a secure certified CC EAL5+ chip, which provides a high level of protection for storing private cryptocurrency keys. The device operates on the basis of the BOLOS operating system, specially designed to work with crypto assets. Important security elements are a recovery phrase consisting of 24 seed words and a PIN code consisting of 4 or 8 digits. When performing an outgoing operation, the user must enter the PIN code directly on the device. At the same time, neither the computer nor the smartphone with which Ledger Wallet is synchronized have access to this confidential information, which guarantees maximum security of user assets.
