Hello, this wallet website https://wallet.trezor.io/#/ Is it official
Yes I can confirm that this is our official web wallet, however it has already been replaced by Trezor Suite the main interface for your Trezor hardware wallet. So the web wallet will be slowly deprecated.
More info in following article:
However, trezor suite does not support simplified Chinese. I hope trezor suite can support simplified Chinese as soon as possible, so that Chinese users can get a better experience.
You can still use wallet.trezor.io however it won’t be updated as Trezor Suite interface so you might not be able to use some feature in the future.
Also, there is a project of translating Trezor Suite in several languages with a help of our community.
You can join this project as well. For more information please see following link:
