Trezor Model One: discontinued, here is the replacement
Last reviewed 2026-08-12
Trezor Model One is discontinued
Do not buy a Trezor Model One: it is discontinued, and Trezor points buyers to the Safe 3 instead. The Model One earned its place in bitcoin history as the world's first hardware wallet, launched by SatoshiLabs in July 2014, but the current Safe line does everything it did on newer hardware, including a certified secure element chip the Model One never had.
For a decade the Model One was the default budget recommendation: two buttons, a small monochrome screen, fully open-source firmware, and a track record long enough that its attack surface was among the best understood in the industry. Its known weakness is physical: with no secure element, an attacker who has the device in hand and specialist equipment can extract the seed, which is why a strong passphrase was always the standard advice for Model One owners.
It also never supported some widely held assets, XRP and Cardano among them, a gap Trezor itself cited as a reason to upgrade. If you own one, it still works with Trezor Suite, and Trezor has committed to continued security maintenance for existing devices. For a new purchase, the Trezor Safe 3 covers more coins, adds a certified secure element, and keeps the two-button budget format.
- Made by
- Trezor
- Screen
- 128 x 64 pixel monochrome OLED with two physical buttons

Pros and cons
What works
- The longest track record in the industry: launched July 2014, with its attack surface publicly studied for over a decade
- Fully open-source firmware and hardware designs
- Existing devices still work with Trezor Suite and continue to receive security maintenance
What to watch
- No secure element: with physical possession and lab equipment the seed can be extracted, so a passphrase is essential
- Never supported some major assets, including XRP and Cardano
- Discontinued: Trezor now sells the Safe 3 instead, which adds a certified secure element at a budget price
Frequently asked questions
Is the Trezor Model One still safe to use?
For existing owners, generally yes, especially with a passphrase enabled. The main risk is physical: it has no secure element, so an attacker with the device and specialist equipment can extract the seed. Trezor continues security maintenance for existing devices, but new buyers should get the Safe 3.
What replaced the Trezor Model One?
The Trezor Safe 3, launched in October 2023, is the budget model Trezor now points buyers to. It keeps the two-button format but adds a certified secure element and broader coin support.
Does the Trezor Model One support XRP?
No. XRP was never supported on the Model One. If you need XRP on a Trezor, the Safe devices support it, as did the discontinued Model T.
Was the Model One really the first hardware wallet?
Yes. SatoshiLabs launched it on July 29, 2014, creating the hardware wallet category that Ledger, KeepKey, and everyone else later entered.
