Nano X Review
Ledger is well-known for making highly secure cryptocurrency hardware wallets. The latest model is the Ledger Nano X and it first became available at the end of May.
There are some new features that come with the Ledger Nano X which help to improve on the previous model, which was the Nano S. This one comes with extra space for more apps, a built-in battery, and Bluetooth. Like other hardware wallets from Ledger, the Nano X is very secure, which makes it ideal for storing your private keys as well as interacting with Dapps and wallets.
Multicurrency Support
Up to 100 applications can be installed at the same time on one device, so you won't be forced to choose. It also supports over 1,100 asst, and more are supported every month.
The Supported Crypto Assets page on the Ledge website shows the complete list of all of the assets that it supports. The page allows you to search by an asset to see whether or not it is supported. For each of the assets, Ledger lists the devices that support the asset, and the Nano X is nearly always one of the ones that are included. There is even a Ledger roadmap that you can view from the page to see if there are any plans to support an asset in the future.
Security
Nano X comes with state-of-the-art security, which is one of its best features. Ledger claims a strong security model is used by the hardware wallet and based on the security spec from earlier Ledger wallets and strong reviews, it isn't hard to believe that this claim is true.
There have been concerns raised over the Bluetooth component of the Nano X. However, Ledger did some careful planning before it included Bluetooth and has implemented key security features as well. The Bluetooth connection stays encrypted so, you are able to enjoy the benefits that come with having a connection without having to worry about security.
If your Bluetooth connection were hacked somehow, your crypto would still be protected by the Secure Element by requesting consent before any action was taken. It is also critical that only data that the Bluetooth transports is public information. On the other hand, any critical data, which includes your private keys and seed, never leave the Nano X.
Also, the Bluetooth implementation on this hardware wallet depends on a state-of-the-art protocol. That ensures authentication via pairing, and that is based upon numeric comparisons. AES-based encryption ensures additional confidentiality.
For people who still are not comfortable using the Ledger Nano X Bluetooth abilities, the feature can be disabled. For there you can use the USB-C cable instead.
Nano X Security Impact and Architecture
The Nano X features new architecture that is slightly different than what the Nano S has. It features wireless support, dual-core MCus, state-of-the-art Secure Element, and two chips
The Secure Element serves as a proxy and the MCU is responsible for the connection with the smartphone or desktop. In addition, the Smart Element drives the screen to display critical information and obtain user input.
It handles security as well, which includes storing the seed and private keys and implementing cryptographic operations for managing cryptocurrencies.
Bluetooth Capabilities
Despite all of the above reassurances, a majority of people want more information on its Bluetooth and what impact it has on the Ledger Nano X's security. Bluetooth Low Energy (BLE) is used by the device, and only public information is transmitted over Bluetooth.
So even if the Bluetooth link, the STM32 MCU, or your smartphone or computer get compromised, you are still required by the Secure Element to verify the transaction prior to it being processed. The Nano X screen will show the real transaction details also and won't ever send out a transaction signature without getting your consent first.
The Bluetooth's state-of-the-art protocol that the Ledger Nano X uses is a two-phase protocol for BLE connection. It uses the BLE channel and includes a key exchange. A random generator is used by both the Ledger Nano X and smartphone for genearating unique keys.
Pending approval from the users, the Elliptic Curve Diffie Hellman's key exchange is used by the two devices to determine the trust between the devices. Specific configurations are used by the Bluetooth protocol that is designed to prevent Man-in-the-Middle Attacks that are commonly seen in BLE.
State-of-the-art security configuration is in the form of Numeric Comparison. A numeric code is displayed by both devices once the common secret is generated. You will verify that the code matches. The code is unable to have collision or downgrade attacks because it is computer from public keys via AES-CMAC along with random nonces. The smartphone and Ledger Nano can get a secure channel established that comes with AES-based encryption following key exchange protocol.
The ST stack implements the BLE stack. Ledger Donjon, the security team, evaluates the security of the implementation that is related to the most recent attacks.
Real Mobility
Compared to other crypto key hardware wallets that are similar, the Ledger Nano X has something unique about it which is the fact that it is genuinely mobile. Between the Ledger Live mobile application and Bluetooth capabilities, you really are able to manage your cryptocurrency from wherever you are. Opening up your computer isn't necessary for managing your crypto.
Remember that the Nano X is unable to fully operate on its own. You must use a desktop computer or smartphone to manage secure transactions, check the balance of your account, add in accounts, or to install applications.
It is very important to also be aware that a 100 mAh battery is featured with the Ledger Nano X. This battery is able to last for several hours when it is being used or for several months when it is fully charged and idling. The battery cannot be replaced, but it is easy to recharge using the included cable and USB-C port.
Ledger Live App
one of the key aspect or using Ledger devices, including Ledger Nano X, is Ledger Live. When this application is used it streamlines the process of utilizing your hardware wallet and provides you with access to all of your accounts in one place from wherever you are. The app is available for both computers and smartphones.

This application allows you to use real-time rates to check your crypto asset balance, regardless of the place or time. It isn't even necessary for your Nano to be connected in order to take full advantage of the feature. Also, Ledger Live allows you to directly remove or install applications from your Ledger Nano X. That allows you to tailor applications based on your individual needs while your private keys are protected. Even when you decide to uninstall an application, your accounts still stay safe.
The Ledger Live Onboarding process is simple, There are easy step-by-step instruction, a fast configuration, and then a check of the authenticity of your device. You can remove or install currencies, location new apps, as well as manage your Nano X's leftover space.

Ledger Nano S vs Ledger Nano X
The Ledger Nano S is still available. Each of these models services its own purpose and will appeal to different kinds of clients. You can use the LedgerNano X while you are on the go using the Ledge Live application on your smartphone. This is not possible to do on the Ledger Nano s. Therefore, some people might want to have one of each of them and leave their Nano S at home. Another difference is the Nano X is a bit more responsive. However, they have comparable overall performance. The Nano X architecture is an evolution over the Nano S, due to the additional memory and new Secure Element chip.
Conclusion
Ledger's newest hardware wallet is the Ledger Nano X. It builds on the previous hardware wallet's features and also stands out with its Bluetooth connectivity that allows you to use it with the Ledger Live app on your smartphone. The Nano X, like Ledger's other hardware wallet, is highly secure and comes with multiple safety protocols and encryption to prevent many different types of attacks.
Ledger has quickly evolved into the most popular manufacturer of hardware wallets among strong competition from Trezor, its main rival. However, the Nano X is a step up and a really good product. For complete beginners, the setup process is a bit convoluted, but most people will be set it up if they carefully follow the instructions.
If you are shopping for a new hardware wallet or wanting to buy your first one, then we highly recommend that you consider the Nano X.
