When managing cryptocurrency through a hardware wallet, secure communication between your device and browser is essential. Trezor Bridge is the background service that enables smooth and secure interaction between your Trezor hardware wallet and supported web applications.

It acts as a connector, ensuring your transactions remain protected while maintaining a reliable user experience.

What Is Trezor Bridge?

Trezor Bridge is a small software component that allows your web browser to communicate securely with your Trezor device.

Instead of relying on browser extensions, Trezor Bridge runs quietly in the background and establishes a direct connection between your hardware wallet and supported interfaces like Trezor Suite (web version).

Why Trezor Bridge Is Important

Trezor Bridge improves both compatibility and security by:

  • Enabling secure communication between device and browser
  • Supporting all major browsers (Chrome, Firefox, Edge, and more)
  • Reducing connection errors
  • Eliminating the need for outdated browser plugins
  • Ensuring stable firmware interactions

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

How Trezor Bridge Works

When you connect your Trezor hardware wallet to your computer:

  1. Trezor Bridge runs in the background.
  2. It creates a secure local connection.
  3. Your browser interface communicates safely with the device.
  4. All sensitive actions must still be confirmed on the hardware wallet screen.

Your private keys never leave the device — Bridge only facilitates communication.

Compatible Devices

Trezor Bridge supports:

  • Trezor Model One
  • Trezor Model T

Both devices require secure confirmation directly on the hardware screen for every transaction.

Installing Trezor Bridge

Installation is simple:

  1. Visit the official Trezor website.
  2. Download Trezor Bridge for your operating system (Windows, macOS, or Linux).
  3. Install and restart your browser.
  4. Connect your Trezor device.

Once installed, Bridge runs automatically whenever needed.

Security and Privacy

Trezor Bridge does not store:

  • Private keys
  • Recovery seeds
  • Personal wallet information

It only manages secure communication between your device and browser. All critical operations are still verified on the hardware wallet itself.

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 device
  • You experience connection issues

For desktop users of Trezor Suite, Bridge may not be required since communication is handled directly within the application.

Reliable and Secure Connectivity

Trezor Bridge ensures that your hardware wallet connects smoothly to supported web applications without compromising security. It enhances compatibility while maintaining the core principle of hardware wallet protection — keeping private keys offline.
