What is Trezor® Bridge?

Trezor® Bridge is a lightweight background service that enables secure communication between your Trezor® hardware wallet and web browsers. It acts as a translator, allowing applications like Trezor Suite (the official interface for managing your cryptocurrency) to interact with your physical device through USB connections.

When you want to access your Trezor Wallet, perform a Trezor login, or confirm transactions, Trezor® Bridge facilitates this communication without compromising security. Unlike browser extensions that might pose security risks, Trezor® Bridge runs as a separate system service, adding an extra layer of protection.

Note: Trezor® Bridge is different from the Trezor Suite app. While Trezor Suite is the main application for managing your crypto, Trezor Bridge is the behind-the-scenes connector that makes the communication possible.

Frequently Asked Questions

Do I need Trezor Bridge if I'm using the desktop Trezor Suite app?

The desktop version of Trezor Suite typically includes the necessary communication components and may not require a separate Bridge installation. However, if you encounter connection issues, installing Trezor Bridge can often resolve them.

How do I know if Trezor Bridge is running on my computer?

On Windows, check the system tray (bottom-right corner) for the Trezor Bridge icon. On macOS, look in the menu bar. Alternatively, you can check your system's background processes. If your Trezor device connects successfully to Trezor Suite or the web wallet, Bridge is functioning correctly.

I'm having connection issues with my Trezor device. Could Bridge be the problem?

Yes, connection problems can sometimes be traced to Trezor Bridge. Try these troubleshooting steps:

  • Restart Trezor Bridge or your computer
  • Reinstall the latest version of Trezor Bridge
  • Try a different USB cable or port
  • Check if your antivirus or firewall is blocking Bridge
Is Trezor Bridge available for Linux?

Yes, Trezor Bridge has versions compatible with most Linux distributions. You can download the appropriate package from the official Trezor website or often install it through your distribution's package manager.

What's the difference between Trezor Bridge and the Trezor Suite app?

Trezor Bridge is a communication tool that runs in the background, enabling connection between your Trezor device and applications. Trezor Suite is the full-featured application where you actually view your portfolio, send and receive cryptocurrency, and manage your device settings. Think of Bridge as the "plumbing" and Suite as the "control panel."

Can I use my Trezor without installing Trezor Bridge?

Some modern browsers support WebUSB, which may allow connection without Bridge. However, this method can be less reliable and secure. Trezor Bridge is the recommended approach for consistent performance and enhanced security. The desktop version of Trezor Suite may not require a separate Bridge installation.
