Originally launched on July 29, 2014, the Trezor One was the world’s first cryptocurrency hardware wallet, setting a new benchmark for digital asset security. Over a decade later, it remains a relevant and widely used device in the crypto community. As of 2025, the Trezor One continues to retail for €69 (approximately US$75) on the official Trezor website, and it supports over 1,000 cryptocurrencies, including Bitcoin (BTC), Ethereum (ETH), and Litecoin (LTC), though it still lacks native support for coins like Ripple (XRP), Cardano (ADA), and Solana (SOL). In this Trezor One review, we will look at whether the Trezor One is still a good device one decade later.
The device runs on firmware version 1.13.0, released in February 2025, which includes enhanced passphrase handling and improved phishing protection. According to SatoshiLabs, the manufacturer, the Trezor One remains secure for most users when used with best practices, such as enabling the passphrase feature and storing recovery seeds offline. However, the hardware vulnerability identified by Kraken Security Labs in 2020—requiring physical access and specialized equipment—still applies, as it would require a hardware redesign to fully mitigate.
Despite newer models like the Trezor Safe 3 and Trezor Model T offering color touchscreens and expanded coin support, the Trezor One remains a cost-effective and reliable choice for users prioritizing simplicity and proven security.
Security Features
Security Features
The Trezor One continues to offer a robust suite of security features designed to protect users’ digital assets. As of firmware version 1.13.0 (released February 2025), the device includes the following protections, according to SatoshiLabs:
- Tamper-Evident Packaging: Devices are shipped in sealed boxes with holographic stickers. Users are strongly advised to purchase only from the official Trezor store and to avoid using any device with signs of tampering. If your box seems to have been tampered with, DO NOT use it and contact their customer support immediately.
- PIN Protection: Access to the device is secured by a user-defined PIN. The PIN entry interface randomizes the number layout on the device screen to prevent keylogging.
- Passphrase Support: Users can enable an optional passphrase feature, which acts as a 25th word to the recovery seed. This creates hidden wallets that are inaccessible without the correct passphrase, even if the recovery seed is compromised.
- Recovery Seed: During setup, users are provided with a 24-word recovery seed. This seed is the only backup of the wallet and must be stored offline and securely. Trezor recommends using a metal backup solution for long-term durability.
- U2F Authentication: Trezor One functions as a Universal 2nd Factor (U2F) hardware token, allowing secure authentication for supported web services.
- Wipe Code: A “self-destruct” PIN can be configured. If entered, it will wipe all private data from the device and reset it to factory settings.
- Passphrase Entry on Device: Since firmware 1.9.0, users can choose to enter their passphrase directly on the device, reducing exposure to malware on connected computers.
- Kraken Security Labs Vulnerability: The physical attack disclosed by Kraken in 2020—requiring voltage glitching and physical access—remains theoretically possible. However, SatoshiLabs maintains that enabling the passphrase feature effectively mitigates this risk for most users. A full hardware redesign would be required to eliminate the vulnerability entirely.
Trezor emphasizes that physical access attacks are only a concern for a small percentage of users and that best practices—such as using a passphrase and storing the recovery seed offline—are sufficient for most threat models.
Can the Trezor One be hacked?
The Trezor One remains a secure hardware wallet for most users, but it is not immune to all forms of attack. The most widely discussed vulnerability stems from a physical attack method known as voltage glitching, first demonstrated by Kraken Security Labs in 2020. This technique involves physically accessing the device, manipulating its microcontroller, and extracting the recovery seed using specialized equipment and custom scripts.
As of June 2025, SatoshiLabs, the manufacturer of Trezor, confirms that this vulnerability still applies to the Trezor One. It cannot be fully mitigated through firmware updates alone, as it is rooted in the hardware design. A complete redesign of the device would be required to eliminate the risk entirely.
However, Trezor emphasizes that:
- The attack requires physical access to the device and cannot be executed remotely.
- Enabling the passphrase feature—which stores an additional word not saved on the device—effectively protects against this type of attack, even if the recovery seed is extracted.
- The threat model is relevant to a small subset of users (estimated at 6–9%) who face targeted physical attacks.
Trezor Model One 1.9.0 firmware update- does it fix the Kraken Security Labs hack?
The Trezor Model One firmware version 1.13.0, released in February 2025, introduced several improvements, including enhanced multisig handling, Ethereum token support, and reworked PIN processing2. However, according to SatoshiLabs, this update does not resolve the hardware vulnerability disclosed by Kraken Security Labs in 2020.
That vulnerability involves a voltage glitching attack that can extract the recovery seed from the device’s microcontroller. Because the flaw is rooted in the STM32 hardware architecture, it cannot be patched via firmware. SatoshiLabs has consistently stated that a complete hardware redesign would be required to eliminate this risk.
As of June 2025, the Trezor One still uses the same microcontroller and remains susceptible to this physical attack. However, SatoshiLabs emphasizes that:
- The attack requires physical access and specialized equipment.
- Enabling the passphrase feature—which stores no data on the device—effectively mitigates the risk, even if the recovery seed is extracted.
- The vulnerability is relevant to a small subset of users (estimated 6–9%) who face targeted physical threats.
For users with elevated security needs, SatoshiLabs recommends considering newer models like the Trezor Safe 3 or Safe 5, which include secure elements and hardware-level protections against such attacks.
How can I keep my cryptocurrencies safe?
Trezor continues to recommend the following best practices:
- Always purchase devices from the official Trezor store to avoid supply chain tampering.
- Enable the passphrase feature for added protection.
- Store your recovery seed offline and never share it digitally.
While newer models like the Trezor Safe 3 and Safe 5 have introduced hardware-level countermeasures, the Trezor One remains a viable option for users who follow proper security hygiene and do not face high-risk threat scenarios.
