Trezor Bridge — Secure Connection Layer for Trezor Devices

Trezor Bridge is a small background application that allows your web browser to communicate safely with your Trezor hardware wallet. It acts as a secure connection layer between your device and Trezor Suite (web version), ensuring that your wallet can be detected and used without exposing private keys online.

In simple terms, Trezor Bridge helps your computer “talk” to your Trezor device when using a browser-based setup.

🔌 What is Trezor Bridge?

Trezor Bridge is a lightweight communication tool developed by Trezor. It runs quietly in the background on your computer and enables secure interaction between:

• Your Trezor hardware wallet

• Your web browser

• Trezor Suite (web interface)

• Enabling wallet access in Trezor Suite web

• Allowing firmware updates and setup steps

• Ensuring stable communication between device and app

This makes the setup experience smoother and more reliable.

When installed, Trezor Bridge runs in the background and listens for secure requests from Trezor Suite.

The process works like this:

1. You open Trezor Suite in your browser

2. The app requests access to your Trezor device

3. Trezor Bridge detects the request locally

4. It securely connects the browser to your hardware wallet

5. Your device is now ready for interaction

At no point are your private keys exposed to the internet.
