Trezor Bridge

Secure communication software that enables your Trezor hardware wallet to connect with web-based applications and services.

What is Trezor Bridge?

Trezor Bridge is a lightweight background service that facilitates communication between your Trezor hardware wallet and web browsers. It acts as a secure intermediary, allowing you to interact with your cryptocurrency assets through web interfaces while maintaining the highest security standards.

Unlike browser extensions, Trezor Bridge runs as a standalone application in the background, automatically starting when needed and remaining available for any Trezor-compatible web application.

Key Benefits

  • Enhanced Security - Maintains the security model of your Trezor device
  • Cross-Platform - Compatible with Windows, macOS, and Linux
  • Automatic Updates - Ensures you always have the latest security features
  • Browser Agnostic - Works with Chrome, Firefox, Edge, and others
  • Background Operation - Runs silently without interrupting your workflow

How Trezor Bridge Works

Trezor Bridge establishes a secure communication channel between the Trezor Wallet interface (or other compatible web applications) and your physical Trezor device. When you initiate a transaction or need to confirm an action, the web application sends a request to Trezor Bridge, which then communicates with your connected hardware wallet.

This architecture ensures that your private keys never leave the secure environment of your Trezor device, while still allowing convenient interaction through web interfaces. The Bridge handles the translation between web protocols and the USB communication required by the hardware wallet.
