What is Trezor Model One?
The Trezor Model One is widely recognized as the first hardware wallet ever created for cryptocurrency storage. It was introduced in 2014 by Satoshi Labs, a Czech-based company that helped define the standards for secure self-custody in the early crypto industry.
At a time when most users were relying on vulnerable software wallets and exchanges for storage, the Model One introduced a fundamentally new model: private keys stored offline, isolated from internet-connected systems.
Launched shortly after the Mt. Gox exchange collapse, the Trezor Model One answered a growing need for secure access to digital funds, especially among early crypto enthusiasts who understood the importance of financial sovereignty. It provided users with a dedicated, tamper-resistant device to protect their assets in a previously unavailable way.
Available today through the official Trezor Store and authorized resellers, the Model One remains a respected choice in the market. While many devices have followed, its legacy as the hardware wallet that sparked the evolution of secure cold storage keeps it relevant among new users and long-term holders.
A decade later, it’s still considered one of the best hardware wallets for those seeking simplicity, transparency, and control.
Trezor Model One Review: Security Architecture
The Trezor Model One implements a deterministic, air-gapped architecture that isolates private keys from any internet-connected environment.
Over years of use, we’ve observed no failures or vulnerabilities under real-world conditions. The device has been immune to malware infections, phishing attacks, and unauthorized access attempts.
The Trezor One is a reliable hardware wallet capable of securing long-term holdings when paired with strong passphrases and good seed storage practices.
1. Microcontroller and Open Design
Unlike newer wallets that use secure elements, the Trezor Model One operates on a general-purpose ARM Cortex-M3 microcontroller (STM32F205). This choice enables full transparency of the hardware and firmware stack.
Although it does not incorporate a secure element, the security model is based on physical access protection, strong user-controlled authentication layers, and open-source firmware, allowing the crypto community to continuously review and improve the device’s codebase.
While some critics highlight the absence of a secure element, this is an intentional tradeoff. Trezor’s model favors transparency and user-auditable code over reliance on closed-source hardware modules.
This choice is acceptable and preferable in our own threat model, particularly when combined with cold storage practices and proper recovery seed handling.
2. Isolated Key Handling
All cryptographic operations (including key generation, transaction signing, and seed handling) are executed entirely within the Trezor Model One’s secure runtime environment. The private keys never leave the device, even during signing operations.
Host devices (PC or mobile) only receive the signed transaction data through the USB interface. This architecture prevents malware on the host system from accessing seed phrases or recovery seeds.
3. Seed Generation and Recovery
The Trezor Model One follows the BIP39 standard for mnemonic phrase generation and BIP32/BIP44 for hierarchical deterministic wallets. Upon initialization, it generates a 12 or 24-word recovery seed, which users must store securely offline. This recovery seed is the sole backup mechanism for restoring the wallet on another Trezor device or a compatible third-party wallet with native support.
A passphrase feature (BIP39 optional 25th word) can be enabled to create a hidden wallet layer. This method increases entropy without altering the original seed, allowing plausible deniability and compartmentalization of crypto assets.
4. PIN Code and Anti-Brute Force Protections
Access to the device is secured with a user-defined PIN code (up to 50 digits). The PIN entry interface is randomized on the host screen and mapped to a static grid on the device display.
An optional passphrase acts as an extra security feature, adding a layer of protection to the standard PIN code and recovery seed.
This deters keyloggers and screen capture exploits. Failed attempts trigger exponential backoff delays, making brute-force attacks computationally impractical even with physical access.
5. Transaction Verification and Physical Controls
The wallet’s 128x64px OLED screen displays transaction metadata, including recipient addresses and amounts. The user must manually confirm each action using the device’s two physical buttons. Since all sensitive data is rendered on the device screen, and input requires tactile interaction, man-in-the-middle attacks from compromised host systems are effectively neutralized.
6. Firmware Security and Updates
The Trezor Model One only runs signed firmware released by SatoshiLabs. Firmware images are cryptographically verified before installation. If tampered firmware is detected, the device refuses to execute it.
In our usage, firmware updates via the Trezor Suite app and Trezor Bridge have been frequent but stable, with no compatibility or data loss issues.
Trezor Model One Review: Supported Assets
The Trezor Model One supports over 1,450 coins and tokens, including major cryptocurrencies such as Bitcoin (BTC), Ethereum (ETH), Bitcoin Cash (BCH), Litecoin (LTC), Dash, Ethereum Classic (ETC), and Dogecoin (DOGE). The wallet also supports thousands of ERC‑20 tokens through integration with Trezor Suite or third-party wallets like MetaMask.
However, there are some limitations. The Trezor One does not support newer protocols or features for handling Cardano (ADA), XRP, EOS, or Monero (XMR). These are supported only on the Trezor Model T and Trezor Safe 5, which feature extended compatibility and native support for a broader range of crypto assets.
The Model One also does not support NFTs. While it can technically connect to DApps through third-party wallets like MetaMask, it does not offer native support for viewing or managing NFTs in the Trezor Suite. This functionality is only practical on more advanced models like the Trezor Model T.
Despite these differences, the Trezor One supports all the most popular coins that the average user uses and remains sufficient for anyone focused on Bitcoin, Ethereum, and ERC‑20 tokens. For users who need broader coin and token support or active involvement in DeFi, newer models may be a better fit.
Trezor Model One Review: UI/UX
All Trezor hardware wallets, including the Model One, rely on the same companion application: the Trezor Suite. As a result, the core user interface and overall experience are nearly identical across devices like the Trezor Model T and Safe 5, with only minor differences related to hardware capabilities.
The Trezor Suite app is clean, functional, and intentionally minimal. While it lacks visual flair or advanced personalization, it delivers a stable and consistent experience across Windows, macOS, and Linux. Core actions such as sending and receiving assets, managing multiple accounts, and updating firmware are clearly laid out. Coin control and Tor integration also add privacy features that are appreciated by advanced users.
On-device interaction with the Trezor Model One is basic, relying on Trezor’s screen and two physical buttons. The small OLED screen shows key prompts, but due to its limited size, operations like entering a seed phrase or verifying long addresses may feel slower compared to devices with a touch screen.
That said, the experience remains highly usable. For most users, the difference between the Model One and higher-end Trezor devices is hardware convenience rather than software capability. If you’re comfortable with a button-based interface and don’t require a visual upgrade, the overall experience is virtually the same.
Trezor Model One Review: Usability
The Trezor Model One supports Windows (10+), macOS (10.11+), Linux, and Android through the Trezor Suite app and Trezor Bridge. It connects via a USB cable and has fast onboarding and a minimal learning curve.
The Trezor Suite interface is localized in over 20 languages, including English, German, Spanish, French, Portuguese, Russian, Japanese, Chinese, and Korean. Language detection is automatic during installation, but users can manually switch language preferences in the settings.
iOS is unsupported, as the Model One lacks Bluetooth or Lightning connectivity. This makes the device incompatible with iPhones and iPads without adapters or workarounds.
All device actions (transaction approvals, PIN input, recovery confirmations) are done using two physical buttons and confirmed visually on the device’s monochrome screen. The absence of a touch screen limits interaction speed for more complex features like multisig support or managing decentralized applications.
The Model One integrates natively with the Trezor Suite and is compatible with select third-party wallets, including Electrum, Exodus, and MetaMask (via WebUSB or Bridge). However, native integration with newer DeFi platforms is limited compared to more advanced models.
Support is provided via a ticket-based system and a searchable help center. While there is no live chat, Trezor’s good customer service has consistently provided timely and technically accurate responses in our experience.
If you’re unsure how to get started, Trezor offers a personal 1:1 onboarding session with a Trezor Expert who will guide you through setting up, backing up, and safely using your hardware wallet. The 60-minute live session is available in English for all Trezor devices and costs €99.
