Trezor Bridge — Quick Guide

Fast reference for installing, using, and troubleshooting Trezor Bridge so your Trezor device connects reliably to the Trezor web apps and Trezor Suite.

What is Trezor Bridge?

Trezor Bridge is a small local application that allows your browser or desktop Suite to communicate with a Trezor hardware wallet over USB. It replaces older browser plugin methods and provides a secure bridge between the device and web apps like Suite.

Quick install

  1. Download Bridge from the official Trezor website. Always verify you are on the official domain.
  2. Run the installer for your OS (Windows / macOS / Linux) and follow the prompts.
  3. After install, Bridge runs in the background and opens a local web endpoint (usually at http://127.0.0.1:21325 or similar).
  4. Plug in your Trezor device and open Trezor Suite or the web app; the app should detect the device automatically.
