Trezor Model One and Model T: farewell to two classics

The Model One of 2014 was, by Trezor’s account, the world’s first hardware wallet. Since 8 January 2026 Trezor no longer sells it or the Model T. Do they still work? Yes. Should you upgrade? That depends.

Short answer

Should I replace my Model One or Model T?

Not urgently: both receive critical security updates until at least 2036. But neither has a secure element, so someone with the device in hand and the right equipment can extract your encrypted recovery phrase. Use a passphrase, or move to the Safe 3 (the One’s successor) or the Safe 5 (the T’s successor).

Support

How much longer will they work?

Trezor promises critical security updates until at least 2036 and basic maintenance until at least 2031. The Model T also keeps receiving new coins until at least 2031. After that the devices keep working, but Trezor recommends moving on.

Some coins have already gone: in February 2025 Trezor removed Dash, Bitcoin Gold, DigiByte, Namecoin and Vertcoin from Suite for both models. Trezor also says it is unsure whether the Model One’s limited hardware can handle future post-quantum standards.

The weak spot

No secure element, but there is a fix

In 2020 Kraken Security Labs showed that someone holding a Model One or Model T, with the right kit, could pull the encrypted recovery phrase from its chip in roughly fifteen minutes. A firmware update cannot change that: it is in the hardware.

Trezor’s answer is the passphrase, an extra word that is never stored on the device. Without it, an extracted phrase is useless to a thief. Still using an older model without one? Set it up, or move to a Safe with a secure element.

Upgrading

From a Model One or T to a Safe

The safest upgrade uses a brand-new recovery phrase, so it no longer matters whether the old one was ever exposed.

  1. Order your new Safe

    The Safe 3 replaces the One, the Safe 5 replaces the T. Order straight from Trezor.

  2. Create a new wallet

    Set up the Safe with a fresh recovery phrase. Do not reuse your old words.

  3. Send your coins across

    Connect the old Trezor, choose Send and move everything to addresses on the new Safe, small amount first.

  4. Wipe the old device

    Once everything has arrived, wipe the old Trezor in Suite and destroy the old recovery phrase.

Time for an upgrade?

Order your new Trezor directly from the maker. All three Safe models have a secure element.

Frequently asked questions

Is the Trezor Model T still safe?

Against remote attacks, yes: keys stay on the device and you approve everything yourself. It has no secure element, though, so anyone who physically gets hold of it can extract the encrypted recovery phrase. A passphrase protects against that.

Can I still buy a Trezor Model T?

Not from Trezor’s shop: since 8 January 2026 it sells only the Safe range. Resellers may still have stock for a while. Never buy a second-hand one, as you cannot know who has seen its recovery phrase.

What is the difference between the Trezor One and Trezor T?

The Model One has a small monochrome screen with two buttons and micro-USB; the Model T has a colour touchscreen and USB-C. The T supports more coins, such as Cardano and Solana. Neither has a secure element.

Which coins do not work on the Trezor Model One?

According to Trezor, Cardano, Solana and Monero among others. In addition, Dash, Bitcoin Gold, DigiByte, Namecoin and Vertcoin were removed from Trezor Suite for the Model One and Model T in February 2025.

Does Trezor offer a trade-in discount?

We found no standing trade-in scheme. Trezor states that it is not currently running any long-term official promotion.
