Trezor Bridge® | Connect Your Trezor to Web

Trezor Bridge® is an essential software component that enables secure communication between your Trezor hardware wallet and web-based applications. Designed by the creators of Trezor®, this lightweight utility ensures that your device can safely interact with supported browsers while keeping your private keys fully protected offline.

If you use Trezor with web interfaces such as Trezor Suite Web or third-party crypto services, installing Trezor Bridge is a critical step to guarantee smooth and secure connectivity.

What Is Trezor Bridge®?

Trezor Bridge® acts as a secure connector between your Trezor hardware wallet and your computer’s web browser. Since modern browsers no longer support older plugins, Trezor Bridge replaces them with a safer, more reliable communication layer.

Once installed, Trezor Bridge runs quietly in the background, automatically detecting your connected device and allowing authorized web applications to communicate with it—without exposing sensitive data.

Why You Need Trezor Bridge

Without Trezor Bridge®, your browser may not recognize your Trezor device correctly. This can prevent you from accessing wallet features such as signing transactions, verifying addresses, or managing accounts via web platforms.

Key benefits of Trezor Bridge include:

  • Secure device-to-browser communication
  • Compatibility with major browsers
  • Automatic background operation
  • Protection against unauthorized access
  • Seamless integration with Trezor services

Installing the official Trezor Bridge ensures your wallet remains both functional and secure when used online.

How Trezor Bridge Works

When you connect your Trezor hardware wallet to your computer, Trezor Bridge® establishes a local connection that allows supported websites to send requests to your device. All sensitive operations—such as transaction signing—are still confirmed directly on your Trezor screen.

This means your private keys never leave the device. Trezor Bridge only facilitates communication, maintaining Trezor’s core principle of offline key storage and user-verified actions.

Installing Trezor Bridge®

The installation process for Trezor Bridge is simple and user-friendly. It supports major operating systems, including Windows, macOS, and Linux. Once installed, no additional configuration is required.

After setup, Trezor Bridge® automatically launches when your system starts, ensuring your device is always ready to connect securely to supported web interfaces. For best results, always use the official Trezor Bridge download and avoid third-party sources.

Trezor Bridge and Trezor Suite

While the desktop version of Trezor Suite does not require Trezor Bridge, the web version relies on it for proper device communication. If you prefer accessing your wallet through a browser, Trezor Bridge becomes an essential companion.

Together, Trezor Suite Web and Trezor Bridge® provide a secure yet flexible way to manage cryptocurrencies without sacrificing usability or safety.

Security and Privacy Advantages

Security is at the heart of Trezor Bridge. The software is designed to minimize attack surfaces and prevent unauthorized access attempts. It only responds to legitimate requests from supported applications and never stores sensitive information.

Additional security advantages include:

  • Encrypted local communication
  • No cloud dependency
  • No access to private keys
  • Open-source transparency

Using Trezor Bridge® ensures your interactions with web wallets remain protected at all times.

Troubleshooting and Updates

Keeping Trezor Bridge up to date is important for compatibility and security. Updates often include performance improvements, bug fixes, and enhanced browser support.

If your browser fails to detect your Trezor device, reinstalling or updating Trezor Bridge® usually resolves the issue. Always close conflicting wallet software and ensure only one connection method is active at a time.
