TREZOR One Review: A Trusted Hardware Wallet, Worth Buying?

The TREZOR One is a trusted cryptocurrency hardware wallet that has stood the test of time. In this detailed review, we look at its strengths and weaknesses and assess whether it is still worth buying in 2019.

Introduction

Established in 2014 in the Czech Republic, Trezor is one of the most well established and trusted cryptocurrency security companies. Trezor hardware wallets are developed and produced by SatoshiLabs, a company that was founded by cryptocurrency veteran Marek Palatinus and places a strong focus on open-source code.

Trezor and SatoshiLabs have the accolade of producing the first-ever hardware wallet for cryptocurrency storage, and as such, it has developed a cult following in the cryptocurrency community. Trezor currently has two hardware wallets on the market, the newer, more expensive Trezor Model T, and the classic Trezor One, much like Ledger offers the Ledger Blue and its bestseller, the Ledger Nano S.

Each Trezor wallet works on the principle of ‘zero-trust.’ In terms of asset security, Trezor works on the expectation that even secure cryptographic systems might become compromised.

This makes Trezor devices one of the most secure ways to store crypto private keys available. In this article, we take a closer look at the classic Trezor One and find out if it can still compete with the more expensive, upgraded Trezor Model T.

Additionally, you can read our Trezor Model T review for an in-depth look at what this hardware wallet offers.

Device Features

The Trezor One is a really compact device, fitting easily in the palm of your hand, and features a simple design, with a small screen and two buttons for navigation on the front.
The Trezor One is around the same length as the Ledger Nano S, but it’s larger width allows for a decent sized screen which fits 6 lines of information on – enough to verify a transaction without text rolling off the screen like Ledger’s device.

Unboxing the Trezor One  

The Trezor One comes in slimline packaging, and one of the first things users will notice is the tamper-evident seals on each end of the box.

Underneath these, there’s a second layer of glue securing the packaging together – this is so users can be sure no one has modified their device before delivery. In the box, users will find their device comes with a USB cable, albeit a very short one, and a small lanyard for the Trezor One. Additionally, Trezor includes logo stickers in the box, alongside instruction manuals, and two sheets for your 24-word recovery seed phrases.

It’s highly likely that the majority of users will find that their favorite coin is supported on the Trezor One, and likewise, the Trezor One supports all ERC-20 based tokens.

Major supported assets include:

However, there are some notable missing assets from the Trezor One, including Ripple (XRP), Cardano (ADA), Monero (XMR) and Tezos (XTZ).

Setup and Transacting

Setting up the Trezor One is simple and straightforward. New users first connect the device to their computer using the USB cable provided and install the Trezor bridge. The Trezor bridge allows communication between your device and computer, and it contains the essential steps for setup.

Once you’ve plugged in your device and launched bridge, these are the next setup steps:

  • Choose a unique PIN code – Like most hardware wallet, Trezor will ask users to set a pin. This can be any number from 4 – 6 digits. Trezor displays the numbers in a mixed order on your device screen and have you click the corresponding squares on your computer – keeping your PIN entry private.
  • Note down your seed phrase – Although Trezor actually let you skip this step, it’s highly recommended that you don’t. Write down your 24-word seed phrase on one of the cards provided and keep it secure – lose your seed phrase, and you will lose your funds!
  • Update firmware – At this stage the Trezor bridge will also check your device is running the latest firmware, to keep your Trezor One protected from threats.

Now, you’re ready to start making transactions with the Trezor One. It’s one of the fastest setups of any hardware wallet, and for advanced users, the option to skip seed phrase confirmation can save a lot of time.

Security Features

Trezor is well known for the completeness of its security approach, so much so, that it’s completely transparent with any issues identified with its hardware wallets, and discloses the information publicly. In addition to a 24-word seed phrase and PIN access which are standard in most hardware wallet devices, Trezor also integrates other security features into its wallets.

Upon loading the Trezor One, the bootloader will verify the device’s firmware signature. The Trezor One will only run if the firmware if from SatoshiLabs, showing users a warning message if the firmware has been altered.

Security Features
Security Features

Each Trezor device is a single purpose computer. This means that there are no additional features which could become compromised, and the device is simple and built for one purpose – to protect users funds. This is especially important, as the recent announcement by competitor hardware wallet manufacturer Ledger to integrate Bluetooth connectivity into the new Ledger Nano X has drawn criticism from some who claim it’s a potential vulnerability.

Finally, the Trezor One’s hardware is ultrasonically welded, which sounds like something out of sci-fi, but means it’s virtually impossible to restore un-noticed once it’s been broken open.

Pros & Cons

ProsCons

Pros and Cons
Pros and Cons

Should you buy the Trezor One?

Unboxing – In the box, users get the bare essentials but not much else. The USB 2.0 cable, for example, is extremely short to the point where it’s not particularly functional, and the small lanyard doesn’t hold much utility either.

The Device – The device itself is lightweight, functional, easy to use, and slimline. However, compared the Ledger Nano X or KeepKey wallet, it’s relatively utilitarian and doesn’t offer much in the way of design or luxury.

Coin Support – Coin support has recently been expanded, and the range of supported digital assets on the Trezor One rivals that of the Ledger devices. Most users will find their favorite assets are supported, including all ERC-20 tokens. However, some major market cap coins are missing from the Trezor One, such as Ripple, Cardano, and Monero.

Security – Security is where Trezor has established itself as an industry leader, and the Trezor One is no exception. The Trezor One is a secure place to store crypto assets, and Trezor is constantly updating its firmware to stay on top of new threats.

Our Verdict

If you’re looking for a battle-tested hardware wallet, you’d be pushed to find one with better security credentials than the Trezor One. Trezor’s commitment to open source code makes its devices auditable, transparent, and open for constant improvement.

Verdict
Verdict

Additionally, Trezor One is now a very affordable hardware wallet. At a fraction of the cost of its newer cousin the Trezor Model T, but with practically the same coin support and virtually equal security hardware, the Trezor One is still a great choice for casual users who just need a device which they use infrequently.
