The buttons are also used to confirm or decline transaction signing. The chassis possesses a textured black plastic finish that offers a sense of sturdiness, however, sitting on it or exposure to high temperature is definitely not recommended.

The Striking Features Of Ledger Nano S

Below are some of the most amazing features of the device.


The Ledger offers some security features that are unique in the industry. The Ledger family of the cold wallets are solely the fully certified cold wallets in the market that have been certified by ANSSI, a French cybersecurity agency. It features what is commonly known as a “secure element”. Specifically, the secure chip that has been used is basically a ST31H320 with a CC EAL5+ certification. It is a black colored medium sized chip located in the top left of the device.

As per Ledger,

“A Secure Element is a secure chip that…embeds intrinsic countermeasures against many known attacks. This kind of chip is tamper-resistant and protects your device to a range of different attacks.”

The secure chip of Ledger is what differentiates it from the other cold wallets that are available on the market in respect to the key storage. 

PIN Code

On your first initialization of the Ledger, you will always be prompted to set up a 4 to 8 digit PIN code. This PIN is the thing that permits you to open the device and use it and works similar to your bank’s account PIN. This is a very important step. However, you need to keep in mind that this PIN is not required for restoring a wallet from the seed words.

It is solely a simple password for making sure that in case you lose your device, all your coins cannot be stolen easily. This also prevents the attackers from attempting to brute force the PIN and acquire access to your coins. 

Backup Using The BIP39 Recovery Seeds

The Nano S of Ledger permits you to backup your cold wallet utilizing a standard known as the BIP39, which in short means that your private key is converted into an easily readable series of 24 words. If you ever lose your wallet or if the wallet gets destroyed or stolen or you cannot remember the PIN, you have to input this series of words into another hardware or software wallet that will fetch your coins back.

You can also find in the box in which your Ledger came a couple pieces of paper for noting down this series of words while you are conducting the device setup. However, backing up your Ledger following this method is not very secure. If this piece of paper is misplaced or damaged by any means, you will run out of luck. This is the reason why a group of people chooses to use a device named Billfodl for storing this set of words on pieces of stainless steel that cannot be penetrated by fire and flood.

There was once a customer of Billfodl who had more than $1,000,000 of Bitcoin backed up on just a notebook and locked it in a fireproof safe. His garage got flooded with 6 feet of rain and the safe became waterlogged. Thus, he lost everything.

Support For Passphrase

Currently, the Ledger Nano S supports the passphrase feature that can also be referred to as the 25th word protection. This security measure permits the users to add an extra word to their existing 24 word recovery phrase. There are mostly two reasons that make you follow this process.

(i) You would like to have extra security to your recovery phrase in case any other person finds your 24 words. In thai case, you would also need to remember that anyone having your 24 words holds the ability to recover your coins and flee with them. Adding another word to the existing 24 words of your choice means that they would know the word that you have chosen as well.

(ii) You would want to create a “dummy account” in your device that contains a small amount of coins. This protects you from the “$5 Wrench attack.” If you ever fall victim to such an attack, you would have a paraphrase set up that will lead to the plausible deniability regarding your larger account of the coins. You on;y tell the burglars about the small account of yours and hope that they would leave with very few of the stored coins. 

Support For Multi-signature

A couple of the advanced cryptocurrency investors utilize more than a hardware wallet for signing the transactions. This shields the investors as it means that even if someone gains an access to one of your hardware wallets or cold wallets or even finds a vulnerability in the software, they would still require an additional cold wallet for accessing your coins.

The Ledger Nano S can be used as one of such devices that makes it more appealing than the hardware wallets that cannot be used in a sold wallet offering multi-signature. One of the easiest ways to set up multisig utilizing a Ledger Nano S is to pair the device with Blockstream Green.

The Trust Factor

Currently, the Ledger Nano S does not ship with the tamper resistant tape for preventing the attackers from opening the box and hence manipulating the device prior delivery. Instead, it offers a software solution for all the users to determine if

(i) The device is a legit Ledger Nano S device.

(ii) The device is not tampered.

It is possible for the device to achieve this benefit through its “Root of Trust” toolkit. How does this work? Well, when you run the tool on the received device, the servers of the Ledger send a message to the device. The device will only respond if it possesses a specific private key on the device. In case, the device failed to respond, it would mean that the device is either not legit or has been compromised and that you must on use it. However, this needs to be kept in kind that the toolkit will be effective if you use it BEFORE transferring any funds or coins to the device. If the device is compromised and you send funds to the device, the tools would not function as your funds will likely be gone by the time you will find about the mishap.
