A Great Tool for Cryptocurrency Investors
There’s no «one size fits all» wallet. Wallets come on different platforms with different features. The Ledger Nano X is the newest crypto hardware wallet, and is very easy to use. DropBit is new, but is very easy to use and friendly for new Bitcoin users. It supports Bitcoin only, but offers Lightning network support. Electrum is a Bitcoin-only wallet that has been around since It’s easy to use, but has advanced features.

This tech-heavy description does not bitcoin ledger wallet review much to the average consumer, though, which is why I am going to explain it in plain language, describing what makes the Bitcoin Ledger Wallet Nano tick.
The wallet launched in early December and for more background on the project you can catch up on our launch coverage. It is roughly the size of a small flash drive, measuring 39 x 13 x 4mm 1. The box also contains a simple manual, recovery sheet and security card in black faux leather pouch.
USB flash drive on the right included for reference. I have no major complaints about the build quality, although some rough edges are visible upon closer examination. The plastic device features an aluminium swivel cover with a brushed finish like many USB drives. In fact, the design looks eerily similar to Super Talent’s Pico-A series flash drives.
Ledger’s familiar design is where its similarities to traditional USB drives end. The smartcard has been an industry standard for decades and eliminates a number of security issues that may arise on devices based on multipurpose microcontrollers. The wallet is obviously not designed as a standalone device, as it relies on the host computer to set up and execute transactions.
Since the host computer is the most likely point of failure, the Bitcoin Ledger Wallet Nano is designed to render vulnerable or even compromised computers safe, by introducing another layer of security. The wallet signs bitcoin transactions internally and aims to prevent man-in-the-middle MITM attacks by employing a security card.
Without this added security layer, the wallet would be exposed to MITM attacks, as a hacker could, in theory, gain control of the computer and proceed to compromise the wallet. The security card makes such an attack less likely by providing physical two-factor authentication. No transaction can be signed without human interaction — each transaction requires the user to visually scan the security card when prompted by the wallet app.
The wallet displays the payment address and asks the user to enter codes for four random parts of the address. If the right code is not entered, a transaction cannot take place. The Trezor hardware wallet, which we reviewed a few months ago, employs a screen to tackle this problem, prompting the user to enter the PIN on a pseudo-random numeric pad, visible only to the user.
The Ledger team opted for a different approach in the form of a security card with 58 pairs of characters. The basic idea is the same, but the implementation is a bit different.
Using a card in place of a screen obviously allows for a smaller device and keeps the overall cost. The trade-off is that it also results in fewer possible permutations of the second-factor code. A persistent attacker with complete control over the user’s PC could in theory reconstruct the security card after a few dozen transactions.
Each transaction would provide the attacker with more ‘depth’ until sufficient information is collected to fully map and reconstruct the contents of the security card. As odd as it may sound, using the wallet on a number of different malware-ridden PCs would, in theory, be safer from an anti-MITM perspective than using it to make a few dozen transactions on your own computer.
Ledger is aware of these limitations and is working to develop a mobile companion app that will essentially allow another device to act as a screen for the wallet. The app will be paired to the wallet using the security card, allowing the wallet to display the challenge on the mobile device, along with the target address and amount of BTC.
The user will then be able to sign the security challenge and facilitate the transaction. The wallet is designed for use on desktop operating systems on Google’s Chrome browser. I used an Asus Windows 8. The installation process is relatively straightforward, but requires the use of a Google Chrome app. While comparatively popular, Chrome is not the only browser on the market and millions of users still rely on Firefox, Safari and even Internet Explorer.
A platform-agnostic approach would have been preferable, but for a number of reasons, including security certificates, it is simply not feasible. Linux users also need to create a set of udev rules to allow access to the device. Once the app is ready, the user is prompted to enter the PIN. The user can choose the PIN or use one suggested by the installer. Then comes the recovery seed — when the wallet is initialised, it generates a word mnemonic seed which must be stored, preferably on the included recovery sheet.
Don’t try this at home — the seed should be written down and stored safely. The seed is displayed only once and must not be stored on your computer, in digital form. The seed is the only way of restoring the wallet in case of loss or hardware failure. This can be done using a replacement Ledger wallet, but the process also works on alternative BIP39 wallets like Electrum. The Ledger Nano must be initialised on an uncompromised computer. In addition to the word recovery phrase, the neatly arranged recovery sheet also includes the security card recovery QR code, which can be used to create a new copy of the second-factor security card in case of loss or theft.
If you punch in the wrong PIN three times in a row, the wallet will reset itself to factory condition. This is also the easiest way of wiping the device in case you want to sell or gift it.
Once the installation is complete, the user simply needs to insert the device into a USB port and enter the PIN in order to access the wallet. However, all transactions must be validated using the security card.
The wallet will issue a challenge and the user needs to follow instructions and enter the four-character code to validate the transaction. This is done by entering the corresponding characters from the security card. The wallet itself is easy to use and anyone familiar with bitcoin wallets should feel at home.
The only difference is the added layer of validation with the security card. Fortunately the whole process is simple and fast — usually taking no more than seconds per transaction. The wallet also features a QR scanner. Despite the fact that QR scanning has limited applications on desktop platforms, I used it to simulate topping up a mobile wallet and it worked fine. It could be quite a time saver in some situations. Overall there is not much to say about the wallet — and this is a good thing — it’s more or less a regular bitcoin wallet with an added layer of authentication, which doesn’t take up a lot of time.
Conclusion There is no such thing as absolute security, but the goal of hardware wallets is to make any potential attack more difficult and resource-intensive.
Ledger is no exception — it is designed to render attacks impractical by raising the bar. It’s not an expensive, specialised piece of hardware for the select few, it’s geared toward the everyday bitcoin user. The device can fit on a keychain and the security card in practically any physical wallet, which makes the Ledger very practical. If you lose either component, you can still recover your wallet using your mnemonic seed.
The upcoming companion mobile app should boost security and bring Ledger on a par with more expensive solutions.

Using the wallet Once the installation is complete, the user simply needs to insert the device into a USB port and enter the PIN in order to access the wallet. Pros Very compact and sleek design.
The Ledger can fit on any keychain, but don’t forget the security card. The use of a smartcard in lieu of general purpose microcontroller should boost security and reliability in the long run Validation via security card does not take a lot of effort or time Cons The device must be installed on a perfectly safe computer and not every user will be keen to use the ‘air gap’ approach.
The security card approach has its own pros and cons. While it helps keep the cost down and allows designers to create a truly pocketable device, it also provides slightly lower levels of security than a device with a dedicated screen. However, this issue could to some extent be addressed by the upcoming companion app. Can’t be used on mobile devices, support is currently limited to Chrome browser. Written by Trace Mayer, J.
