Trezor Model One vs Model T comparison: which one to choose in 2025?
Are you hesitating between the Trezor Model One and the Trezor Model T to secure your cryptocurrencies ? Here's a complete comparison to help you make the right choice based on your needs, expectations, and budget. The Model One is appealing because of its price, while the Model T boasts advanced features. Here's what truly sets them apart.
Table of contents
Price difference between the Trezor Model One and the Model T
For many, the primary criterion remains price:
- Trezor Model One : around €69
- Trezor Model T : approximately €129
The doubling of the price between the two models mainly reflects technical differences that we will explore below.
Trezor Model One vs Model T: Design and ergonomics
Display
- Model One : small monochrome OLED screen (128 x 64 px), navigation via two physical buttons.
- Model T : color touchscreen (240 x 240 px), navigation entirely via the screen.
The Model T allows you to enter your PIN and confirm transactions directly on the touchscreen, making the interface faster. In contrast, the Model One is readable, but requires navigating with two buttons, which slows down certain operations.
Case and materials
- Model One : basic plastic, compact (12g), very lightweight format.
- Model T : more robust plastic, rear magnetism for dock, weight of 22g, more refined finish.
Trezor Model One vs Model T: Supported Cryptocurrencies
Digital asset support is one of the most significant differences between the two models. Although they both use Trezor Suite , their compatibility varies depending on hardware capabilities.
Native support via Trezor Suite
The Trezor Model One supports major cryptocurrencies such as Bitcoin , Ethereum , Litecoin , and ERC-20 tokens . However, it does not natively support blockchains such as:
- Cardano (ADA)
- Ripple (XRP)
- Solana (SOL)
- Tezos (XTZ)
The Trezor Model T , meanwhile, supports all assets available through Trezor Suite, including those mentioned above.
In summary, the Model T is much better suited to a modern multi-chain wallet, while the Model One is suitable for more limited use, focused on Bitcoin, Ethereum and their ecosystems.
Trezor Model One vs Model T: Features and software compatibility
Compatibility with wallets, dApp, and advanced features
The Trezor Model One and Model T are both compatible with major operating systems , including Windows , macOS , Linux and Android (via OTG cable). On iOS , only read-only access is available.
They can be used with Trezor Suite as well as with third-party software wallets such as MetaMask , Electrum , or Exodus . Browser-based connectivity relies on the WebUSB and WebHID , ensuring direct compatibility with Chrome, Brave, and other modern browsers.
Connecting to dApp
Neither model directly supports dApp via Trezor Suite. To interact with applications like Uniswap or Aave , you need to use an extension like MetaMask by connecting your wallet as a secure device. The Model T offers more comfortable navigation thanks to its color touchscreen , while the Model One requires manual confirmations via its two buttons. For more optimal integration with decentralized applications, we recommend checking out Ledger models .
microSD card (only on the Model T)
The Trezor Model T allows you to insert a microSD card to activate a local PIN encryption function. Once this option is activated, the PIN is no longer only verified by the device, but also linked to an encryption file stored on the card.
In practical terms, this means that even if someone steals your Trezor and knows your PIN, they won't be able to do anything without the associated microSD card. The device will refuse to function until this card is inserted.
It is a form of double physical locking, comparable to a padlock with two keys: one digital (the PIN), the other physical (the card).
This card is not used to store your seed, crypto, or files. And since the Trezor Model One doesn't have a microSD card slot, it cannot offer this additional level of security.
Support for Shamir Backup (SLIP-39)
- Model T : compatible
- Model One : not compatible
Shamir Backup allows you to divide the recovery phrase into several parts (for example, 5 parts, 3 of which are needed for restoration), which can be stored separately on different physical media. This method reduces the risks associated with the loss or theft of the single seed phrase.
Trezor Model One vs Model T: Safety, notable differences
Open source firmware
Both models use the Trezor Core , which is 100% open source and can be verified on GitHub .
Secure on-screen keyboard
- Model T : PIN entry directly on the touchscreen
- Model One : computer input, hidden by an offset keyboard
The Model T offers stronger PIN isolation, since it is never entered via the computer.
Secure Element
Neither the Model One nor the Model T has a Secure Element (EAL6+ certified cryptographic chip). For that, you'll need to look at the latest Trezor Safe or Ledger . For more details, please see our Model T vs. Safe 5 comparison .
Trezor Model One vs Model T: Technical performance
- Model One : ARM Cortex-M3, 120 MHz
- Model T : ARM Cortex-M4, 180 MHz
Model T 's processor is faster and newer, allowing for smoother execution of operations, especially when signing complex transactions.
Trezor Model One vs Model T: Recommended Use Case
Choose the Model One if:
- You primarily hold Bitcoin , Ethereum , or ERC-20 tokens.
- Are you looking for a simple, low-cost wallet?
Choose the Model T if:
- You own assets such as Cardano , XRP , Solana
- You want to use a touchscreen for greater autonomy and comfort
- You want an advanced backup (Shamir)

Conclusion: Trezor Model One or Trezor Model T?
The Trezor Model One remains an excellent choice for beginners or for storing traditional assets like Bitcoin or Ethereum at a lower cost. The Trezor Model T is aimed at more demanding users who want to manage multiple blockchains, use a touchscreen, and take advantage of advanced features such as Shamir Backup or extensive cryptocurrency support.
The choice therefore depends on your needs: simplicity and budget for the Model One , versatility and comfort for the Model T.
