a Ledger Nano S hardware wallet



Ledger Nano S is among the popular hardware wallets for securing your crypto assets. It has a strong reputation that makes it worthy of your attention. It would be wise to learn everything about this hardware cryptocurrency wallet before deciding if it's for you or not.

So, let's look into the Ledger Nano S security, features, and functionality!


Is the Ledger Nano S Secure?

There are numerous hardware wallets available - and yet, finding a secure hardware wallet might not be as easy as you hope. Ledger devices are often praised for their innovative security solutions, though - and the Ledger Nano S device is no exception.

The main role of a hardware wallet is to store your private keys. Without this information, you wouldn't be able to authorize any outgoing transactions on the blockchain network. While all hardware wallets strive to provide full isolation between private keys and the device, they're not equally successful at this task. As a result, your assets can be vulnerable to hacker attacks.

Ledger has succeeded at developing cryptocurrency hardware wallet technology that delivers the highest level of security for your assets. Their Ledger Nano devices incorporate a certified secure chip (Secure Element) and a proprietary OS (BOLOS), meant to support the security features of the Secure Element. The combination makes the system tamper-resistant.


Nano S Security Features

All Ledger cryptocurrency wallets - the Ledger Nano X, Nano S, and Ledger Vault - combine the leading smart chip technology and the added proprietary elements. The company also continuously audits the security of its devices and software to disclose any uncovered vulnerabilities. With their certification, Ledger strives to create wallets that will ensure a higher level of digital asset security to those working with critical information.

The Cold Storage

The principle of isolation, also called cold storage, means that your private key is never “hot” - or online. Even when you connect your Ledger Nano S to a desktop computer or mobile device, private keys will not be exposed to the Internet.

The Secure Element

The previously mentioned Secure Element ensures the highest level of isolation by storing the private key and limiting the interaction with the rest of the device. The Ledger Nano S wallet has two layers of protection:

  • ST31H320 (security) chip

  • STM32F042 (OS) chip

These chips store your private keys - but they also sign transactions as independent pieces of hardware.

You will need to use your PIN code if you wish to unlock your Ledger Nano S wallet and add a paraphrase for granting access. All users must confirm transactions by physically pressing both buttons on the Ledger physical device, too.

Moreover, the SE can ensure that the device you're connected to has not been compromised by verifying its integrity.

The Root Of Trust

Ledger didn't place all its eggs in one basket. They knew the anti-tampering seal cannot always guarantee the user's safety, which is why they've made sure their software tools can verify that the piece of hardware hasn't been tampered with.

The software in charge of this critical role is called “Root of Trust” - an app that helps minimize supply chain attacks.

Recovery Phrase

The 24-word Recovery phrase is found on the Recovery sheet that you receive with the Ledger Nano S. It acts as a backup for your digital assets, and as long as you have it, you can access your funds or restore your device.

That's why it's crucial to store your Recovery sheet in a secure location. If anyone gets a hold of this info, they could steal your funds without the PIN code.

If you're not sure what your Recovery phrase is, you can use the Recovery Check in the Ledger Live application to verify the Recovery phrase and correct any spelling mistakes.

Do NOT lose your recovery seed! If you do, you won't be able to recover your digital assets.


Nano S Security Features Review

The level of security in the Nano S is so high that it's never been hacked remotely. The multiple layers of protection make it better than most other hardware wallets on the market - the ideal device for storing coins.

As long as you're vigilant and ensure your PIN, seed phrases, and other security provisions are never online, your crypto assets will remain safe. The compact design of Ledger Nano S allows you to attach it to your keys, wallet, or bag so that there's less risk of misplacing it.

Here's another proof of the quality of encryption and authentication used in Ledger Nano S:

It's currently the only hardware wallet certified for its security by the French Cybersecurity Agency (ANSSI). So, yes, you can use the Ledger Nano S to store your cryptocurrency worry-free!
