Trezor Support

Hi there,

The reason certain Trezor knowledge base pages are blocked in the UK is due to strict local regulations from the Financial Conduct Authority (FCA). Because Trezor is an international company, UK law classifies many online crypto guides and support articles as unauthorized financial promotions, meaning access has to be restricted for UK IP addresses to maintain legal compliance.

We know this is frustrating when you just need troubleshooting help, and our teams are actively working to update our content to meet these local requirements so we can restore access as soon as possible.

My first ever hardware wallet and I love it. The only limitation is that they don't support many blockchains so I need to buy another hardware wallet to compliment of which I recently bought onekey classice pure and it came faulty, very dissapointed in onekey. Overall, trezor 3 is good but team needs to add more blockchain support so user won't go for faulty hardwares.

Your questions, answered

What’s the difference between Trezor Safe 3 and Trezor Model One?
The Model One focuses on a more hands-on approach to crypto security with its OLED display and intuitive button interface. Trezor Safe 3 prioritizes security with its Secure Element chip and offers easy usability with a monochromatic screen and two-button input.
