Trezor Model One: discontinued, here is the replacement

Do not buy a Trezor Model One: Trezor removed it from its own e-shop on January 8, 2026 and 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, nothing is urgent. Trezor's own notice promises basic maintenance until at least 2031 and critical security updates until at least 2036, and existing devices keep working in Trezor Suite. The one long term caveat Trezor adds is about post-quantum cryptography: it expects the Safe series and even the Model T to handle new signing and firmware verification standards in software, and says it is uncertain whether the Model One can, because of hardware limits.

For a new purchase, the Trezor Safe 3 covers more coins, adds a certified secure element, and keeps the two button budget format at $59.
