Trezor Bridge: Secure Communication Between Your Trezor Device and Browser

What Is Trezor Bridge?

Trezor Bridge is a communication service developed by Trezor that enables your computer's web browser to interact securely with a Trezor hardware wallet. It acts as a background application, allowing compatible web applications and the official Trezor ecosystem to detect and communicate with your connected device.

Trezor Bridge improves compatibility across modern browsers and provides a more reliable connection than older browser-based communication methods. It is commonly used alongside Trezor Suite and other supported wallet interfaces.

Why Trezor Bridge Is Important

When you connect your Trezor hardware wallet to a computer, the browser cannot communicate with the device directly. Trezor Bridge creates a secure channel that allows approved applications to exchange information with the hardware wallet while keeping your private keys safely stored on the device.

Key benefits include:

• Secure communication between browser and hardware wallet

• Automatic device detection

• Improved browser compatibility

• Reliable firmware communication

• Seamless connection with supported wallet applications

How Trezor Bridge Works

The process is simple:

1. Install Trezor Bridge on your computer.

2. Connect your Trezor hardware wallet using a USB cable.

3. Open a compatible application, such as Trezor Suite or another supported wallet interface.

4. Trezor Bridge detects the device and establishes a secure connection.

5. All sensitive operations, including transaction approvals, remain protected by confirmation on the hardware wallet itself.

Your private keys never leave the Trezor device, helping maintain a strong security model.

Features of Trezor Bridge

Secure Device Communication

Trezor Bridge provides encrypted communication between supported applications and your hardware wallet without exposing sensitive information.

Cross-Platform Support

Trezor Bridge is available for major desktop operating systems, including:

• Windows
