In this review, we will be looking at the features of the hardware wallet, the cryptocurrencies it support, and if it is worth buying or not.

Key Features of the Trezor Model T
- Screen: Bright color LCD – 240×240 pixels;
- Connectivity: USB-C connector for connecting to the computer or mobile phone;
- Mobile support: Android support via the Trezor Manager; and
- External wallet compatibility: supports MyEtherWallet and a few others.
Passwords on the device are individually locked with the Trezor Password Manager using a user’s digital keys. The device can also function as a U2F hardware token, which allows Trezor to utilize the screen and inform a user about any authentication request before they approve it.
Trezor created the standard recovery seeds (BIP32/39/44), which enables users to recover their entire wallet easily with the help of their 12-word recovery seed.
Similar to the Trezor One, the Model T has a passphrase feature so users can generate a new wallet. To access passphrase protected wallets, users will be required to enter your passphrase in addition to your security PIN.
So say a thief demands you to give them access to your device. You can give them your PIN code to access a wallet with fewer funds. Meanwhile the bulk of your crypto assets are stored safely behind passphrase protected wallets.
Can the Trezor 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 reveal the recovery seed. According to Kraken Security Labs, 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.
Trezor Model T 2.3.0 firmware update- does it fix the Kraken Security Labs hack?
In mid-April 2020 the Trezor Model T announced their latest firmware update to ver. 2.3.0 which features some updates on their security measures. Before we answer whether it can resolve the 15-minute hack devised by Kraken Security Labs earlier this year (see above section), let’s take a look at what these features are.
The new updates include 2 passphrase updates which firstly, allow temporary passphrase caching so you can switch between your various passphrase protected wallets when using the device. The passphrase cache is only temporary, so once you disconnect the device, nothing is saved. Secondly, users will now be asked to choose how to enter their passphrase on the device itself, rather than on your computer or phone.
A notable new features is the wipe code which acts as a “self-destruct PIN”. When entered either on the device itself or your computer or phone, the wipe code erases all private data from your Trezor and resets the device to the factory defaults. Trezor suggests users can write the wipe code somewhere near your device as a decoy PIN, so if a thief tries to unlock your device, they will make the Trezor erase itself.
The SD card protection feature is intended to serve as an additional protection against physical attacks on the Trezor Model T. When this feature is enabled, a randomly generated “secret” is stored onto the microSD that is inserted into your Trezor. This “secret” carries no information on your Trezor’s seed or passphrase and is a completely random value. With the feature, you would need to insert the SD card into the Trezor so as to combine the “secret” with the PIN and decrypt the data stored on the Trezor. Hence you will require both the SD card and the Trezor to unlock it and access your cryptocurrencies. So you can enable this feature and keep the SD card and your Trezor in separate locations if you are worried about physical attacks.
From our research, Trezor has not directly responded whether their latest security firmware update fixes the hack devised by Kraken Security Labs. As mentioned previously, the vulnerability identified by Kraken cannot be resolved unless the hardware is redesigned. So the latest firmware updates can only indirectly give hackers have a harder time accessing your device but not resolve the core vulnerability. The fact that it only took Kraken 15 minutes of physical access to the device to hack it, and their suggestion that the glitching tool could be mass produced for sale at around USD$75 continues to be extremely worrying. For this reason, whilst we appreciate Satoshi Lab’s efforts to continue improving the device we cannot reinstate the security score given to the Trezor prior to the Kraken hack being discovered.
Trezor Model T is designed to handle over a thousand cryptocurrencies including popular ones like Bitcoin, Ethereum, Litecoin, Dash, Bitcoin Cash, Bitcoin Gold, and more. Regular updates enhances features and allows for even more supported cryptocurrencies. One advantage of the Trezor over other wallets is that all currencies are accessible without the need to “install” individual applications – this simplifies the overall use of the device

Multi-currency support 3/5
3rd Party Wallet Support
3rd party wallets like Exodus Wallet and others (MetaMask, etc.) offer Trezor support and allow for access to the hardware wallet inside of Exodus. This means users will be able to choose between different wallet interfaces and enjoy unique features offered only by Exodus, such as direct exchange of currencies.
The device is relatively compact at 2.52in x 1.54in x 0.39in (64mm x 39mm x 10mm) and weighs 0.77 oz (22 grams).
It also has an LCD size of 240 x 240 pixels.
With the LCD screen, users can edit and configure the wallet according to their taste.
The sleek design makes it an upgrade to the previous Model One. Instead of buttons, the device has a touch screen available for ease of use.
However, I find the touch screen is still small and can be hard to use. I eventually settled on pressing the screen with my pinky finger.
The device works with a broad range of operating systems. Thus, users won’t have the problem of connecting it with Windows, Linux, MacOS. They also have Chrome extensions available for those who wish to use it. The user interface gives users the option to change the language and view transactions via the touch screen.
Hardware design 5/5
Ease of use 4/5
The device supports Android mobile and laptop devices. There is currently no support for iOS.
Users will need to download the Trezor Manager from the Google Play Store, which enables them to manage the wallet from their mobile phones. The mobile app can be used in sending cryptocurrencies, generating addresses, and viewing the details of a user account.
Is Trezor Model T worth it in 2023?
At the official price of US$219 (NOW ONLY $186 UNTIL 21 MAY!), it is an excellent cryptocurrency hardware wallet.
However, some people may consider the price too high despite its functions and high-security level. It is quite an investment if you are new to cryptocurrencies or only trade cryptocurrencies casually.
The touch screen, its support of over a thousand cryptocurrencies, and its high-security features are some of the reasons that could convince people to purchase this crypto hardware wallet.
Deciding whether or not to purchase the Trezor Model T over other available cryptocurrency hardware wallets has a lot to do with what features you are looking for.
The wallet supports over a thousand cryptocurrencies. Thus, virtually half of the cryptos available in the market can be stored on the device.
Its integration with exchanges such as Bitstamp, Coinmap, and Bitex also makes it a good choice.
However, one significant downside is that the device does not support IDEX or Switcheo exchanges. The latest findings from Kraken Security Labs on physical hacks on the device are also extremely concerning.
Security Rating: 3/5
