The Ledger Nano S is one of the best-known crypto lớn hardware wallets, having sold well over a million units worldwide. But does it still cut it in 2021?

What is the Ledger Nano S?

At $59, the Ledger Nano S is one of the cheaper hardware wallets on the market. It supports more than 1,100 cryptocurrencies, và has a sleek thiết kế và simple user interface.

But it's coming up for its fifth birthday in 2021—an eternity in tech hardware terms—and it's since been superseded by its feature-packed sibling, the Ledger Nano X.

So is it worth shelling out for the extra bells & whistles, or does the simpler, cheaper option still have what it takes? We've sầu taken a detailed look at the cài đặt process & what it’s lượt thích lớn use the wallet.

Ledger Nano S: Design and build

The Ledger Nano S isn't going to lớn win any design awards, but neither does it have the clunky aesthetic of rival hardware wallets like the Trezor One.

"Discreet" is probably the best word to lớn describe it; indeed, if it weren't for the Ledger branding etched on its aluminum shield, you could easily mistake it for an old—if slightly chunky—USB flash drive.

Rotate it open, however, & some differences immediately become apparent: there's a (tiny) screen, a micro-USB socket & two buttons atop the device for navigating its menus.

The Nano S is available in a variety of colorways, including green, pink, & a rather fetching transparent mã sản phẩm. As well as letting you coordinate your Ledger with your wardrobe and interior decor, it's also handy for distinguishing between main và backup devices (or, if you're a crypto lớn high roller who wants khổng lồ split up their holdings, between different accounts).

Ledger Nano S: What's in the box?

The Nano S packaging is simple, minimacác mục, và clearly draws inspiration from Apple's designs. Unlike some manufacturers, Ledger doesn't bother with an anti-tamper seal—it argues that the seals are easy khổng lồ counterfeit and can be misleading.

Inside the box, you'll find the Nano S device itself, along with a quiông chồng start guide, three cards for recording your recovery phrase, a micro-USB cable, a lanyard, & a loop for attaching your Nano S to a keyring.

Ledger Nano S: Getting started

To phối up the Ledger Nano S, you'll first need lớn download and install the Ledger Live application; upon launch, you'll need to phối up a password.

Once you've sầu done that, connect your Ledger to your computer using the supplied micro-USB cable, và follow the on-screen prompts lớn set up your device. Most of the next steps are made on the device itself, and are (initially) straightforward—the only thing you'll need to vị is mix up a PIN.

To navigate through the menus, use the two buttons on top of the device; cliông chồng the right button khổng lồ go right/up, the left button lớn go left/down and both buttons khổng lồ select a thực đơn tác phẩm or respond khổng lồ a prompt.

The next step is a little more arduous. The Ledger generates a 24-word secret phrase, which you'll need lớn record on one of the cards supplied with the device. That means clicking through khổng lồ each word, copying it down, double-checking khổng lồ make sure it's accurate, & then re-entering the words to lớn confirm that you've recorded them correctly.

It's a tedious process, but necessary; in a very real sense, the 24-word phrase is your wallet, và the Ledger simply provides a portal through which you access it. If you đại bại your Ledger device (or forget your PIN number), you can enter the recovery phrase on a new Ledger, và still have access khổng lồ your crypto assets. If you lose your recovery phrase, you're stuffed.

Some wallets require you to enter your secret phrase inkhổng lồ an phầm mềm, which then sends it to lớn the device—meaning the hardware wallet is pointless if your phone is hacked or stolen. By keeping the secret phrase airlocked & only held on the Ledger device, security is maximized.

That also means you need khổng lồ keep your recovery phrase very secure. Some Ledger users have resorted khổng lồ recording their 24 words in a metal wallet (thẻ, after all, can be burned or disintegrate in water), or splitting their recovery phrase up and storing it in multiple locations.

Once you've sầu chosen a PIN and recorded your recovery phrase, you'll need khổng lồ verify your device through the Ledger Live sầu tiện ích, which should take just a few seconds.

Ledger Live

The Ledger Live sầu software is, for most users, the main way you'll interact with your Ledger Nano S. Fortunately, it's a beautiful, streamlined app that is very easy lớn use.

Unlike the Nano X, which has Bluetooth không dây connectivity và an internal battery, you'll need to lớn connect the Nano S khổng lồ your computer via a micro-USB cable in order to use Ledger Live sầu. You can also use the Nano S with Ledger Live's Android di động phầm mềm, using the Ledger OTG kit.

Each time you plug the device in, you'll need lớn enter your PIN code.

The first thing you'll need lớn do on launching is khổng lồ add some apps to your Ledger. To do this, navigate to lớn "settings" in the left-hvà column of Ledger Live. You'll be prompted to lớn "allow Ledger Manager" on your device. Here you can kiểm tra whether your device has the latest firmware (and update it if necessary), & add or update apps.

Apps essentially represent cryptocurrency coins or tokens; Bitcoin, Ethereum, Cosmos and so forth. When you install the relevant app, you'll need khổng lồ add an account; this will then show up in the "portfolio" section of Ledger Live.

Once you've installed your apps, you can sover và receive crypto. To receive, you can either navigate lớn the "Accounts" section và pick whichever tài khoản you want to use, or use the "send" and "receive" buttons in the sidebar & select your chosen cryptocurrency from the drop-down thực đơn.

You'll also need to lớn open the tiện ích for the relevant cryptocurrency on your Nano S device.

To sover or receive, you'll need khổng lồ confirm the sending or receiving address on your Ledger Nano S. This can be a fiddly business; it involves checking the address in Ledger Live sầu against the characters on the Ledger's tiny screen (which is so small it can't render the entire address on one screen, forcing you to lớn cliông chồng through khổng lồ see the whole thing).

That's the most painful part of the process, though; once you've done that, it's plain sailing. Sending và receiving crypkhổng lồ is a smooth process; Ledger Live sầu also offers options for buying và selling certain cryptocurrencies directly in the ứng dụng.

Ledger Nano S: ease of use and features

The Ledger Nano S supports over 1,100 crypkhổng lồ assets, 29 of which you can manage directly using Ledger Live sầu. Some of the coins and tokens available include:

However, because of the limited storage capacity of the Nano S, you'll only be able khổng lồ run two or three of the relevant wallet apps on the device at any one time. If you have a diverse portfolio, you might want khổng lồ consider the Nano X as an alternative sầu, as its expanded internal memory means that it's able to lớn store a lot more apps at once.

Ledger Nano S: Security

Obviously the most important part of a hardware wallet is its security credentials, và Ledger hasn't skimped in that regard. Like the Nano X & Ledger Blue, the Nano S has a physically isolated secure element that's CC EAL5+ certified—the highest such rating available against penetration tests.

These secure elements are similar khổng lồ those used in credit cards, passports and SIM cards; in addition, Ledger uses its own proprietary operating system, BOLOS. This ensures that the various applications running on the Nano S, and the 24-word recovery phrase, are isolated from each other, & requires that physical confirmation for each transaction needs to take place.

The Nano S và Nano X are also the only hardware wallets to receive CSPN (First Level Security Certificate) certification, from ANSSI—the National Cybersecurity Agency of France.

While Ledger's physical security is extremely tight—making it one of the most secure cold storage solutions on the market—Ledger the company has had some embarrassing security lapses in the past.

Recently, we shared news of a data dump. On December 23, we were alerted by our e-commerce provider Shopify about an incident in April và June '20 where their rogue team members exported merchants' customer databases. Ledger was included.

Notably, in June 2020, data from its e-commerce database was leaked, with over a million customer records finding their way lớn hacker forums. As a result, some Ledger customers found themselves at the mercy of phishing attacks, & even threats.

As a result, Ledger has committed lớn changing its procedures for handling customer data, though it's scant comfort to those who have had their personal information (và the fact that they hold enough cryptocurrency for it khổng lồ be worth securing in cold storage) exposed.

Ledger Nano S review: Verdict

It may be getting a bit long in the tooth, but at just $59, the Ledger Nano S is a steal—either as a backup device if you already own a Nano X, or as a cold storage solution in its own right.

Its main limitations are its storage capađô thị (meaning that you can only run two or three apps on it at any given time), its tiny screen, & the fact that you need lớn plug it inkhổng lồ a computer to lớn use it. All of these are addressed by the Ledger Nano X, though the extra $60 is quite a steep price increase for the tăng cấp.
