Tokens and cryptocurrencies

Ledger Nano S supports over 1 100 cryptocurrencies, but most of them are ERC20 tokens, which we will not reveal so far in Ledger Live. Part of cryptocurrencies is also supported on Ledger by dedicated applications and applications built by developers of some projects.

Therefore, you need to support the solution and service MyCrypto.com, or her older brother MyCrypto.com Both services offer storage of the majority of cryptocurrencies on the Ledger.

Note: MyEtherWallet/MyCrypto is also resistant to public Wi-Fi networks, so don’t be surprised if you don’t run the site in the public library. The site is not dead, and you just need to use your own Hotspot and cellular data from your phone. Besides, beware of so-called phishing sites, which impersonate the above mentioned services.

It’s been some time since we created our previous MyEtherWallet guide.

So let me give you a brief overview of MyCrypto.

  1. The first thing you need to do is to connect your device to your computer, log in, and then install the Ethereum application on your device. I showed you how to do it above.
  2. Go to the MyCrypto page, go through a short tutorial on security and choose our hardware wallet from the menu.
  3. Then run the Ethereum application on your device and click “Connect to Ledger Wallet” on your computer screen.
  4. In the “Addresses” menu you will find dedicated wallets for different cryptocurrencies but Ethereum (Ether) and ERC20 tokens are only supported at the “Ledger (ETH)” address.
  5. Below are the individual ETH addresses, and on each of them we can keep infinite number of different crypto and tokens. Let’s choose one and click “Unlock”
  6. We can send and receive payments, request payments, keep track of transactions, wallet, network and so on.

Security

I will certainly not exhaust the subject of security in Ledger Nano S, because it is a very complex subject, but at least I will mention a few important issues.

One of them is the so-called “smartcard chip”. It is an intelligent chip with a special security feature. Such chips are used, among other things, to protect biometric data in passports and credit cards. Ledger wrote about this chip like this:

Chips with [this] security feature are extremely difficult and expensive to hack, while “simple” chips, even with security software, require much less effort.

The next element, somehow protecting us, is nothing more than a back up and a phrase of recovery. Moreover, Ledger has created its own proprietary BOLOS™ (Blockchain Open Ledger Operating System), which significantly increases the protection of users against all kinds of attacks. Learn more about BOLOS.

The last thing I would like to mention is the level of security quality according to international standards, i.e. EAL (Evaluation Assurance Level). On a scale from 1 to 7 Ledger Nano S ranks in the category CC (Common Criteria) EAL 5+. More about EAL.
