I bought myself a Ledger Nano S hard wallet and today I’m testing it out for the first time. I’ve been hearing so many good things about the Ledger Nano that I decided to do a TREZOR vs Ledger type of comparison.

Before I begin my review a quick word about Bitcoin hardware wallets. Hardware wallets are probably the most robust form of security you can have for your Bitcoins or any other cryptocurrency. They allow you to send and receive Bitcoins on any computer, even one that is compromised with malware, with the knowledge that your transaction will still go through as intended.

The way the hardware wallets achieve maximum security is by storing your “ pivate Key” (A secret (long) number that allows bitcoins to be spent. The private key is mathematically related to all Bitcoin addresses and public keys generated from it.) and signing your Bitcoin transactions offline so someone trying to “hack” your wallet remotely won’t be able to do so. Most hardware wallets also use a second screen/device to verify actions on your wallet such as signing transaction. This way, if a hacker gains control over your computer, he still can’t do any harm since he requires access to the physical device connected to your computer as well.

I’ve reviewed the former Ledger model, the Ledger Nano in the past. Back then I concluded that the added protection that a TREZOR wallet gives you with its second screen protection is superior to the Ledger Nano. However, the Ledger Nano S now features a second screen feature as well. So this comparison is going to be interesting.

Design and user interface

Design-wise the products are pretty much the same. Both are small and compact, however, the Ledger Nano S does have a slight advantage in the sense that its metal casing makes it more durable in my opinion . Both wallets will both fit pretty easily into your pocket or hand.

The way the Ledger Nano S works is pretty similar to any Hardware Wall ( A bitcoin wallet that uses a physical piece of hardware in order to operate and keep it more secure. Examples of hardware wallets are TREZOR, LedgerWallet and Keepkey. A hardware wallet is usually more secure since it's considered to be a form of cold storage). When you first set it up you will choose a PIN to protect the device from unwanted access. Later, you will receive a 24-word seed that will be used to create your private keys (this is what’s known as an HD wallet, This seed should be written down in a safe place and NOT on your computer, as whoever knows this seed has control over your Bitcoins. A good suggestion would be to write this seed down using a Cryptosteel device.

The Ledger Nano S has two buttons that allow you to control it. The initial set up of the device is pretty simple and takes about 3 minutes. Most of the time is spent on writing down your seed.

This seed creation is one of the places where the second screen comes into play. If your computer is compromised a hacker will be able to see the seed if it’s displayed on your screen. This is exactly why the seed words are shown on the small device screen that is tamperproof, so you know that only you see your seed.

Once the device is set up, all that’s left is to install an app that allows you to interface with the device (i.e. send and receive Bitcoins).

The app I used is a Chrome extension that gives you the following functionalities:

General account details
Sending Bitcoins from your hardware wallet
Generating your Bitcoin address to receive Bitcoins
Settings for your app (e.g. exchange rate, language, etc.)

The app is pretty similar to the one TREZOR uses although it has a sleeker design.

The interface (as shown above) is pretty intuitive and doesn’t require any manual to get the hang of it. Also, you can rename accounts and don’t have to call them in general names like “account #1”. TREZOR allows this as well but requires you to connect a Dropbox account.

The Ledger Nano S can also use existing Bitcoin wallets instead of the current chrome extension interface. Such wallets include MyCellium, Electrum, Bitgo, GreenBits, Copay and MyEtherWallet.

Support of altcoins

The Ledger Nano S includes Bitcoin, Litecoin, Ethereum and Ethereum Classic companion apps, and other Blockchain (The full list of mined blocks since the creation of Bitcoin. There is also a company called Blockchain.info which supplies various Bitcoin services such as a block explorer and a bitcoin wallet but they have no control or authority over Bitcoin's blockchain) -based cryptocurrencies. Here are the current altcoins supported:

•

Nano S Wallet Supports: Bitcoin (BTC), Ethereum (ETH), Ethereum Classic (ETC), Ark (ARK), Bitcoin Cash (BCH), Bitcoin Gold (BTG), Expanse (EXP), Dash (DASH), Digibyte (DGB), Dogecoin (DOGE), Komodo (KMD), Litecoin (LTC), NEO (NEO), Pivx (PIVX), Posw Coin (POSW), Qtum(QTUM), Stealthcoin (XST), Stellar Lumens (XLM), Stratis (STRAT), Ubiq (UBQ), Vertcoin (VTC), Viacoin (VIA), Ripple (XRP), Zcash (ZEC)

You can send and receive payments, check your accounts and manage multiple addresses for each currency from the same device.

TREZOR on the other hand recently announced that they have partnered with MyEtherWallet to support Ethereum on their device as well. Other currencies supported through TREZOR are Dash, Zcash and Litecoin (via Electrum LTC).

Company reputation

Ledger was founded in 2015 in France. The company has since gained substantial traction in the Bitcoin and cryptocurrency sphere and has grown to be a worthy competitor to SatoshiLabs (the creators of TREZOR). TREZOR, on the other hand, has been on the market since 2014.

Both Ledger and TREZOR use open source code for their apps, and both have demonstrated excellent customer support and stability in the past few years. Even though TREZOR is the more mature and respected company, it’s hard to say the Ledger falls behind.

So who’s the winner?

In all honesty, I think the Ledger Nano S wins But both companies created a great product. The Ledger Nano S seems to have the upper hand in design and usability, while TREZOR’s reputation has more impact in the community (although not by much). Since most of us are price sensitive in this case the price tag tips the scale towards Ledger.

Personally, I use a Ledger Nano S, Today I think I may start using both, storing some of my funds on a TREZOR and some on a Ledger. I have to say that the progress Ledger has made in the past year is truly impressive, and their product shows it
