Choosing between hardware wallets can feel overwhelming, especially when both options come from the same trusted manufacturer. The Trezor Model One (formerly Trezor One) and Trezor Model T have been protecting crypto assets for over a decade. While both devices are now discontinued and replaced by the newer Trezor Safe series, many users still own these reliable devices or are considering the secondary market. This comprehensive guide compares every aspect—from security chips to screen quality—so you can make an informed decision about which Trezor fits your needs.

The Trezor Model One holds a special place in cryptocurrency history as the world's first hardware wallet. Launched in 2014 by SatoshiLabs, it established the blueprint for cold storage that competitors still follow today. Despite being discontinued and replaced by the Trezor Safe 3, the Model One continues to receive full security updates and remains a viable option for those who already own one.
The Trezor Model T, released in 2018, represented a significant evolution in hardware wallet design. The touchscreen interface, MicroSD card slot, and advanced backup options positioned it as a premium solution for serious crypto holders. While also discontinued and replaced by the Trezor Safe 5, the Model T remains one of the most feature-rich hardware wallets available on the secondary market.
Security is the primary reason to own a hardware wallet, and both devices deliver robust protection. Understanding the nuanced differences helps clarify which approach fits your threat model.
Neither the Model One nor Model T includes a Secure Element chip—a dedicated security processor found in newer devices like the Trezor Safe series. Instead, both rely on open-source firmware running on general-purpose ARM processors:
The absence of a Secure Element means physical access to either device could potentially enable sophisticated attacks. However, the open-source nature allows the community to verify the security model, and real-world successful attacks remain extremely rare.
The display plays a crucial role in transaction verification:
Both devices support passphrase wallets—an additional password beyond your seed phrase that creates hidden wallets. However, there's a critical difference:
On-device passphrase entry is crucial for security because it prevents your passphrase from being exposed to malware on your connected computer.
The Model T's MicroSD slot enables plausible deniability—you can configure the device to require an SD card for certain operations. This means you could have a "decoy" wallet visible without the SD card and a hidden wallet accessible only with it. The Model One lacks this feature entirely.
Model One: Setup requires connecting to Trezor Suite, updating firmware, and writing down your 12- or 24-word seed. The two-button interface makes navigation deliberate but slow. PIN entry uses arrow buttons to select digits—the process takes longer but feels secure.
Model T: Setup is more streamlined thanks to the touchscreen. You can choose between 12-, 20-, or 24-word seeds, or use Multi-share Backup (Shamir) to split your seed into multiple shares. PIN entry on the touchscreen resembles a smartphone keypad—faster but requires careful attention.
For routine tasks like checking balances, receiving funds, or making transactions:
Both devices work seamlessly with Trezor Suite—Trezor's desktop and web application for managing your portfolio. Features include:
The Model T's larger screen provides a better experience when confirming transactions independently of your computer.
Both Trezor Model One and Model T support an extensive range of cryptocurrencies through Trezor Suite and third-party wallet integrations. According to Trezor's official supported coins page:
The Model T's more powerful processor may provide better performance with newer cryptocurrency protocols and third-party applications. However, both devices handle mainstream cryptocurrencies (BTC, ETH, major stablecoins) identically through Trezor Suite.
Important: Always check Trezor's official supported coins page for the most current compatibility information, as support is continuously updated.
Model One Value: At $69, the Model One offered exceptional value for basic crypto storage. Its simple design, proven security, and open-source foundation made it ideal for beginners and those primarily holding Bitcoin or major cryptocurrencies. The value-per-dollar ratio was unmatched for a hardware wallet with 10+ years of trust.
Model T Value: At $179, the Model T commanded a premium—but justified it with the touchscreen, MicroSD slot, and advanced backup options. For users holding significant portfolios or requiring advanced features like Multi-share Backup, the extra cost provided meaningful security and usability improvements.
Since both devices are discontinued, prospective buyers should consider:
Both the Trezor Model One and Model T remain secure, reliable hardware wallets in 2026, despite being discontinued. Their long-term software support until 2036 means current owners can continue using them confidently.
For current owners: There's no urgent need to upgrade if your device works properly. Both models receive security updates and remain fundamentally sound.
For new buyers: Consider the Trezor Safe series instead. The Trezor Safe 3 (successor to Model One) includes a Secure Element chip at a similar price point. The Trezor Safe 5 (successor to Model T) adds modern features, Gorilla Glass, and improved security. Both benefit from Trezor's latest security architecture.
Between the two legacy models: If you must choose from the secondary market, the Model T offers more features and better usability for the price difference. However, if you find a sealed Model One at a significant discount and only need basic functionality, it remains an excellent security solution.
Ultimately, the best hardware wallet is the one you use consistently. Both devices encourage proper security practices—offline key storage, physical confirmation of transactions, and recovery seed backup. Choose based on your interface preference and feature needs, but prioritize buying from the official Trezor store or authorized resellers to ensure device authenticity.

Looking for Model One or Model T? Check authorized resellers, but always verify device authenticity before use.
The Trezor Model T offers more features including a color touchscreen, MicroSD card slot, and Multi-share Backup support. However, the Trezor One provides excellent basic security at a lower price point. Choose Model T if you want advanced features and a touchscreen interface; choose Trezor One if you prefer a simple, affordable hardware wallet with proven security.
Yes, both devices remain fully supported. Trezor has committed to software updates until at least 2031 and critical security fixes until at least 2036 for both Model One and Model T. However, both models are discontinued for new purchases, replaced by the newer Trezor Safe series.
Both devices support Bitcoin, Ethereum, and thousands of other cryptocurrencies through Trezor Suite. The Model T may have better compatibility with some newer coins due to its more powerful processor. Check Trezor's official supported coins page for the most current compatibility information.
Both devices require connection to a computer or mobile device to view your portfolio and initiate transactions. The Trezor Suite app is used to manage your assets. However, all private keys remain on the device and transactions must be confirmed physically on the hardware wallet itself.
If you lose your Trezor device, you can recover your funds using your recovery seed (backup words). You'll need to purchase a new Trezor or use a compatible wallet and enter your recovery seed in the correct order. This is why it's critical to store your recovery seed securely and separately from your device.

Cryptocurrency investments carry significant risk, including potential loss of principal. Hardware wallets protect your private keys but cannot protect against user error, phishing attacks, or other social engineering. Always conduct your own research and consult with qualified professionals before making financial decisions. Information about supported coins and features is based on Trezor's official documentation as of April 2026 and may change.
Security Note: Only purchase hardware wallets from the official manufacturer or authorized resellers. Never buy used devices or from unverified sources, as they may have been tampered with.
