If you use a Trezor hardware wallet to store cryptocurrency securely, there’s one essential piece of software you need in order to connect that wallet safely to your computer or browser: Trézór Bridge®™. In this comprehensive guide, we’ll explore what Bridge is, why it’s necessary, how it works, and how you can install and use it — all in one friendly, beginner-friendly place.
Trézór Bridge®™ is the official communication interface between your Trezor hardware wallet and the applications that need to talk to it — including web browsers, desktop tools like Trezor Suite, and supported crypto interfaces. :contentReference[oaicite:1]{index=1}
