Trezor Bridge

Secure Communication Between Your Trezor and Browser

What is Trezor Bridge?

Trezor Bridge is a lightweight background service that enables secure communication between your Trezor hardware wallet and web browser. It acts as a vital link that allows you to interact with your cryptocurrency assets through web-based interfaces like Trezor Suite while maintaining the highest security standards.

Trezor Bridge runs silently in the background once installed, automatically establishing connections when you access Trezor-compatible web services. This eliminates the need for browser extensions and provides a more seamless user experience.

How Trezor Bridge Works

Trezor Bridge establishes a secure communication channel between the Trezor device connected to your computer and web applications running in your browser. This is accomplished through a local service that runs on your machine.

Communication Flow

When you connect your Trezor device to your computer and visit a compatible web application like Trezor Suite:

  1. The web application detects that Trezor Bridge is installed
  2. Trezor Bridge establishes a secure local connection with your Trezor device
  3. All communication between the web application and your device is routed through this secure channel
  4. Your private keys never leave the Trezor hardware wallet, maintaining the highest security standard

Trezor Bridge uses a local HTTP server that communicates with the Trezor device via WebUSB, providing a seamless experience similar to native applications while maintaining web compatibility.
