Trezor One: Firmware Update 1.7.2

Today, on December 18th, we have released a new firmware update for the Trezor One, this time with the number 1.7.2. This early holiday present brings you support for the OMNI layer. It is also a sign that the Trezor One keeps on being maintained and developed even as we are working on porting the Trezor Model T firmware back onto the Trezor One.

So let’s look at the details!

The Trezor One firmware update is available in Trezor Wallet (wallet.trezor.io)

OMNI layer (OMNI, MAID, USDT)

The support for the OMNI layer means that Trezor One is now capable of handling OMNI, MAIN, but also the stablecoin USDT — Tether.

U2F fixes

As a part of the update, we are also rolling out U2F fixes for the Trezor One. To be more specific, we have implemented a security fix for a vulnerability discovered by Christian Reitter. As the author reasserts himself, the vulnerability has no discovered practical use yet. For more details, read the technical explanation linked below:

Miscellaneous changes

The Trezor One will also no longer ask you for your PIN, if you have just set one. It is a small cosmetic change, but it will make the initial setup flow a bit smoother.
