Trezor One was launched on 29 July 2014 and was the first ever cryptocurrency hardware wallet. This wallet brought an unprecedented level of security to the burgeoning cryptocurrency field. As such, it paved the way for subsequent upgrades in this field.
The Trezor One retails for 69 EUR (US$78). To buy one, click here.

- Clear screen – The Trezor One features a clear monochrome screen. Trezor uniquely allows you to customise your home screen.
- Integrated exchange support– The device has integrated exchange support so users can trade seamlessly.
- Proven security– Trezor One, being one of the original wallets has a track record of security.
The security features of the Trezor Model One begin in its packaging. The device is inside a completely sealed box together with a hologram sticker. Be sure to only buy your device from the official website. If your box seems to have been tampered with, DO NOT use it and contact their customer support immediately.
Similar to the newer Trezor Model T, passwords on the device are individually locked with the Trezor Password Manager using a user’s digital keys. The device also functions as a U2F hardware token. This allows Trezor to utilize the screen and inform users about any authentications request before approving it.
The device is protected with a private key recovery phrase. This is a 24 word phrase to restore your device.
NOTE: You should write down the phrase offline and kept in a safe place. It is extremely important to keep this phrase outside the view of any camera as anyone can use it to restore your device and steal your funds.
For daily use, the wallet features a security PIN to use the Trezor One. Once your device is connected the digits 1 through 9 shows up in randomised order. You then go to your computer and enter your PIN code based on the location of the digits on your device screen. This is an extra layer of security to prevent keyloggers.
An extra layer of security is the Trezor’s passphrase feature which allows users to generate a new wallet. If you enable this feature, you will be required to enter your passphrase in addition to your security PIN to access those specific wallets.
So say a thief demands you to give them access to your device. You can give them your PIN code which accesses a wallet with fewer funds. Whilst keeping the bulk of your crypto assets stored safely behind passphrase protected wallets.
Can the Trezor One be hacked?
Kraken Security Labs announced they devised a new way to hack into Trezor devices within 15 minutes of physically having the device. They did this through voltage glitching using a device and cracking the PIN code using a custom Python script, which will reveals the recovery seed. According to them, the attack makes use of inherent flaws within the Trezor’s microcontroller. So it will be difficult for Trezor to fix this vulnerability without redesigning the hardware and putting out a new device.
In reply, Trezor noted that the attack cannot work remotely and if users turn on the passphrase feature on the device. Trezor also reassured users that physical access is only a threat to 6-9% of cryptocurrency users.
Whilst physical access i.e. theft may not be the greatest concern to users, such cases are not unheard of and are hugely devastating. And with people posting their lives and daily activities on social media, people can easy mark themselves as a target for thieves. The fact that it only takes 15 minutes of physical access to the device to hack it, and Kraken’s suggestion that the glitching tool could be mass produced for sale at around USD$75 is extremely worrying. For this reason, we have downgraded the security score for this device and the newer Trezor Model T.
Trezor One has support for around 1000 coins including BTC, BCH, Litecoin, Ethereum, Dash, Zcash and Stellar. However, of the most common coins on the market it does not support Ripple (XRP), Cardano (ADA), Monero (XMR) and a number of later ERC-20 coins.
This can be a limitation in comparison with more recent hardware wallets.

Multi-currency support 2.5/5
The Trezor One is relatively compact at 2.36 x 1.18 x 0.27 inches (60x30x6mm), and weighs 0.42oz (12 grams).
It has an 128×64 pixel OLED monochrome display. Despite the screen being small, it is still better than the Ledger Nano S in that cryptocurrency addresses can fit entirely on the screen.
Trezor has the unique feature where you can personalise your home screen. Your device can show off your personality by choosing from 1 of the default pictures or uploading your own.
The device has two physical buttons to help users navigate the wallet functions.
It relies on USB type-B for connection to the computer. However the cable provided is quite short which can be inconvenient when using the device with your computer.
In terms of portability, the device is conveniently small and can easily fit into your pocket. Additionally, some people would enjoy the home screen customisation function.
Hardware design 4.5/5
Ease of use 4/5
The device supports laptops and Android mobile devices. There is currently no support for iOS. Users will need to download the software, Trezor Manager from the Google Play Store. This enables users to use the app to send cryptocurrencies, generate addresses, and view their account details.
Trezor One worth it in 2020?

The device is by no means outdated. Save for a few major altcoins as outlined above the device still supports most major cryptocurrencies.
Unless you really want the colour touchscreen of the Trezor Model T, this older Trezor One device still does what most casual cryptocurrency traders need it to do.
And the lower price point is definitely an attractive factor.
The wallet supports most major cryptocurrencies. However, lack of support for Ripple (XRP), Cardano (ADA), Monero (XMR) and a number of later ERC-20 coins is a serious disadvantage.
Lack of iOS support is also problematic, though this is for any Trezor device.
The device has a decently sized screen. Whilst not as nice as the colour touchscreen of the Trezor Model T, the buttons make it easy to use. Being able to see the entire address on-screen is a huge plus.
Some users may be enticed by the ability to customise your home screen which is a feature unique to Trezor devices only.
