I dare say, this ultimate Ledger Nano S review is all you need, to know everything about this hardware wallet. 

Crypto wallet: Overview 

A crypto wallet acts as an interface that allows users to interact with the blockchain network and the digital assets held in it. 

How do crypto wallets work? 

Whenever a client creates a crypto wallet, they are assigned multiple public keys and a unique private key. A wallet’s public keys represent multiple different public addresses that could be used to receive the cryptocurrencies to the same one. The private key, however, is like a key to a safety box; anyone with the key can access your assets that are present in the wallet.

Blockchain, a public ledger stores the relevant data in something called blocks. These “relevant data” are the records of all the transactions, the owner of the key of those funds, and the asset balances at a given address. Crypto-related assets are present on blockchain and everyone on the network can see those balances at any given time. 

To send the crypto funds, one needs the correct wallet address of the person they are sending it to and vice versa.

Types of crypto wallets: 

  1. Hot wallets: These are digital wallets that are easily accessible through laptops, desktops and mobile devices. Crypto exchanges, online and software wallets are all examples of hot storage wallets. Some of these wallets are operated by third-parties which means that they control and manage the private keys associated with wallets. Furthermore, these wallets are exposed to the internet making them vulnerable to hacking, phishing and other attacks that could lead to theft of client’s assets. 
  1. Cold wallets: These wallets operate in an offline environment while still guaranteeing access to your crypto assets at any time and provide more security. They are, however, less convenient and accessible as they have to be inserted/connected to the devices before every use. For example, Hardware wallets.

Ledger Nano S: Overview  

I think we have already established the fact that Ledger Nano S is a hardware wallet. Ledger launched Ledger Nano S in 2016, which is a multi-currency hardware device.

  8. Stellar 
  9. Cosmos  
  10. Bitcoin Cash
  11. Ethereum Classic

Ledger Nano S costs around $59 USD according to their platform’s current price. The company occasionally free ships the product in the US and a few other international countries, if not, the additional fee is charged for shipping.


The main reason for people to buy hardware wallets or Ledger products is the safety and security of the crypto assets.

  • Ledger provides industry level security for their hardware wallets by using an operating system called BOLOS, which is integrated to a secure chip. 
  • The product has CC EAL5+ certification level and the chips are ST31H320 (secure) + STM32F042 protected. 
  • On the personal level, users have to set a 4-to-8-digit PIN number. After the entire setup, anyone can enter this PIN only three times, if incorrectly filled, Ledger will go into timed lockout. 
  • Users also have access to a 24-word recovery phrase or seed which is unique and acts as an added security layer. It should be written down somewhere safely, if in case the users forget the PIN, it could be used as a passphrase or backup password. 
  • Ledger has multi-signature support. That is, some investors use multiple or at least more than one hardware wallets to sanction the transactions. So, even if the hackers do get access to one of the wallets, they still need to crack others in order to gain access to the funds.  
  • Ledger also provides regular updates against firmware and phishing attacks. 
  • To make sure the device is genuine and not physically tampered, Ledger offers a software solution through a tool, called Root of Trust. When the tool is run on the device it receives a message from Ledger’s server and can only be responded to if the device has a specific private key. If, in case, the device cannot respond to the message that means that the product is a knock-off.
