If you’ve spent any time researching non-custodial crypto storage, chances are you’ve come across Trezor wallets. They’ve been around for a good stretch, staking a solid claim in hardware wallet history. Today, when we talk about "Trezor models," we mostly mean two main offerings available: the Trezor Model One (often called Trezor One or Model 1) and the Trezor Model T. Alongside those, there are a few legacy units and firmware variants still lingering in enthusiast communities — though they aren’t in active production.
In my experience, each Trezor model has its nuances, from the design and supported assets to the security architecture and usability. This article looks beyond surface-level features and digs into what sets them apart and where they overlap, so you can better decide what fits your crypto self-custody style.
The Trezor Model One, sometimes called the Trezor model 1, is the OG in this lineup and one of the earliest widely accessible hardware wallets. It’s known for a few things: a straightforward experience, solid security for beginners, and broad compatibility with major cryptocurrencies.
Opening a Trezor Model One box shows you a clean, minimalist device — small screen, two physical buttons, no frills. In my testing, the setup process is relatively fast, especially since the device connects via USB and relies on a companion web or desktop app. Once plugged in, the device guides you through generating a new seed phrase or restoring from an existing one.
If the Model One is the sturdy, no-nonsense entry, think of the Trezor Model T as its more refined and versatile sibling — a step up in usability and compatibility, and aimed at those who want a few extra bells and whistles.
In my hands-on use, the touchscreen definitely lowers the friction during the initial wallet setup and daily operations. If you’ve ever struggled with button input on smaller devices, this alone is a solid upgrade.
The Model T supports a broader range of cryptocurrencies including many newer ones not compatible with the Model One. If you’re into altcoins beyond Bitcoin and Ethereum, this can be a big deal.
Before the Model One and Model T dominated the market, early Trezor units (like the original Trezor One prototypes or Trezor 3) laid the groundwork. These legacy devices still float around collectors and early adopters.
These older iterations generally have more limited firmware updates and fewer supported coins, so while they might still technically secure assets via seed phrases and private key management, they are best avoided for new purchases.
Also, I recommend checking the current firmware update status before trusting any older model, as security patches have matured significantly in recent years.
Diving into security, there's a notable distinction between models. The Trezor Model One relies mainly on a general-purpose microcontroller trusted by design, not equipped with a dedicated secure element. The Model T, however, incorporates a certified secure element chip that’s designed to be resistant against side-channel attacks, physical probing, and firmware tampering.
But what does this mean in practice? Well, that secure element reduces attack surfaces, especially in scenarios involving physical access. While the Model One is not inherently insecure—it still offers robust cryptographic isolation and multi-layered protections—it’s more exposed to advanced physical attacks.
I personally think that for most users who keep devices in secure environments and use strong seed phrase practices, the Model One’s architecture is perfectly fine. However, if you're handling larger amounts or want peace of mind against more targeted physical threats, the Model T’s secure element is a sensible upgrade.
Also worth noting is both models use air-gapped signing internally. You can find more details on what air-gapped signing means and its benefits in our air-gapped-signing guide.
Every hardware wallet bears its own quirks during day-to-day operations. I’ve found:
Model One users often appreciate the simplicity, but navigating longer BIP-39 passphrases or entering custom passphrases (sometimes called the 25th word) can be a bit cumbersome with only two buttons.
Model T users enjoy smoother input thanks to the touchscreen, which makes passphrase management and complex operations like multisig setups friendlier.
Unremarkably, both wallets require USB connection to a host device. This avoids common Bluetooth risks but also means you need a compatible computer or smartphone adapter.
On the topic of multi-signature wallets, Trezor supports multisig workflows via compatible wallet software — pivotal for those looking to secure assets with more than one signer. This is covered further in our multisig-guide.
Firmware is the lifeblood of hardware wallets. Both Trezor models receive updates from the manufacturer, focused on security patches and adding new features.
In my experience, the update process is straightforward but should never be rushed. You download the firmware file from official sources, verify signatures (there’s a cryptographic check built into the Trezor Suite app), and then flash it onto the device.
Ignoring firmware updates is a common mistake that can leave devices exposed to known vulnerabilities — something I heavily advise against.
Another important aspect is supply chain security. Buying directly from authorized sources and verifying the tamper-evident seal on the box—which Trezor outlines in its supply-chain-unboxing guide—is a safeguard against tampered devices.
One of the big differentiators between Trezor models is crypto support.
| Feature | Trezor Model One | Trezor Model T |
|---|---|---|
| Bitcoin | Yes | Yes |
| Ethereum | Limited (ERC-20 tokens might need external apps) | Full support |
| Altcoins | Limited number | Extensive support |
| NFT Management | No | Supported via integrations |
| Custom Token Support | Basic | Advanced |
For those invested heavily in DeFi tokens or emerging Layer 1 blockchains, the Model T will typically cover more ground out of the box. But if you're a Bitcoin maximalist or mainly hold large-cap mainstream coins, the Model One has your back.

This choice often boils down to a few considerations:
I firmly believe no model fits every niche perfectly. For instance, if you’re after cold storage with multisig architecture, both models can work but will depend on your wider setup and software wallet compatibility.
On the flip side, users who prioritize minimalist devices that don’t need touchscreen or color displays may find the Model One a better daily companion.
When weighing Trezor models, understanding the trade-offs helps you pick a wallet suited to your unique needs and future growth. The Trezor Model One continues to serve many as a no-nonsense, trustworthy guard of private keys, while the Model T upgrades the experience by adding secure element hardware and a user-friendly touchscreen.
Whichever you consider, remember that hardware wallets are only as secure as your seed phrase and backup strategy. Keep your recovery phrase safe (consider metal backups outlined in backup-strategies) and verify firmware updates regularly.

In my experience with both models, your wallet choice is just one link in a chain of good crypto hygiene — but one you’ll rely on every time you sign a transaction or safeguard your digital fortune.
