— 2 min read

Trezor Bridge is the official communication tool that connects your Trezor to your web browser. It acts as a secure bridge between your Trezor device and supported browser-based applications, ensuring smooth and encrypted communication.

If you use the web version of Trezor Suite, Trezor Bridge enables your browser to recognize and interact with your hardware wallet safely.

What Is Trezor Bridge?

Trezor Bridge is a lightweight background service installed on your computer. Once installed, it allows supported browsers like Chrome, Firefox, and Edge to communicate securely with your Trezor device via USB.

It replaces older browser extensions that were previously required and offers improved compatibility, reliability, and security.

Why Is Trezor Bridge Important?

When using web-based wallet interfaces, browsers cannot directly access USB hardware devices for security reasons. Trezor Bridge solves this by:

  • Enabling secure device-to-browser communication
  • Providing encrypted data transfer
  • Ensuring compatibility across modern browsers
  • Allowing safe transaction confirmations

Without Trezor Bridge, your browser may not detect your Trezor device properly.

When Do You Need Trezor Bridge?

You typically need Trezor Bridge if:

  • You are using the web version of Trezor Suite
  • Your browser does not recognize your Trezor device
  • You receive a prompt to install Bridge during setup

If you are using the Trezor Suite desktop application, Trezor Bridge is usually not required.

How to Install Trezor Bridge

  1. Visit the official Trezor website.
  2. Download the latest version of Trezor Bridge for your operating system (Windows, macOS, or Linux).
  3. Run the installer and complete the installation process.
  4. Restart your browser if prompted.

Once installed, Trezor Bridge runs quietly in the background and does not require manual operation.

Final Thoughts

Trezor Bridge plays a critical role in maintaining secure communication between your hardware wallet and browser-based applications. It ensures encrypted, stable, and reliable connectivity without compromising security.

For the highest level of security, many users prefer the Trezor Suite desktop app. However, when using the web interface, Trezor Bridge is the trusted and official connection software that keeps your crypto transactions secure.
