Trezor Bridge

A secure communication layer that connects your Trezor hardware wallet to supported web applications.

What Is Trezor Bridge?

Trezor Bridge is a background service that allows your web browser to securely communicate with your Trezor hardware wallet. It acts as a trusted bridge between your device and web-based wallet interfaces, ensuring that sensitive operations are handled safely.

When using browser-based Trezor applications, Trezor Bridge replaces outdated browser plugins with a modern, secure solution that works seamlessly across supported operating systems.

Why Trezor Bridge Is Important

Modern web browsers no longer support traditional hardware wallet plugins. Trezor Bridge solves this limitation by enabling secure device communication without compromising security or usability.

• Enables browser-to-device communication
• Eliminates the need for insecure browser plugins
• Improves compatibility with modern browsers
• Maintains offline private key protection
• Officially developed and maintained by Trezor

How Trezor Bridge Works

Trezor Bridge runs silently in the background after installation. When a supported website needs to interact with your Trezor device, it sends a request through Trezor Bridge rather than directly accessing the hardware.

All cryptographic operations, such as signing transactions or verifying addresses, take place inside the Trezor device itself. Trezor Bridge only transmits approved data and never accesses your private keys.

When Do You Need Trezor Bridge?

Trezor Bridge is required when using Trezor with web-based wallet interfaces or third-party services that run directly in your browser. It ensures smooth communication between your Trezor device and these platforms.

If you use the Trezor Suite desktop application, Trezor Bridge is typically not required, as the desktop app connects directly to the device.

Supported Operating Systems

Trezor Bridge is available for the most common desktop operating systems, allowing users to connect their devices securely across platforms.

• Windows
• macOS
• Linux

Always download Trezor Bridge from the official Trezor website to ensure authenticity and security.

Security and Privacy

Security is the foundation of Trezor Bridge. The service is designed to minimize attack surfaces while preserving strong hardware-based protection.

Trezor Bridge never stores sensitive information, never requests your recovery seed, and never performs actions without your physical confirmation on the Trezor device.

Common Use Cases

Trezor Bridge is commonly used when accessing:

• Web-based Trezor Wallet interfaces
• Third-party cryptocurrency services
• Decentralized applications that support Trezor
• Browser-based account management tools

Troubleshooting Trezor Bridge Issues

If your browser does not recognize your Trezor device, ensure that Trezor Bridge is installed and running correctly. Restarting the service or reconnecting the USB cable often resolves connection issues.

Disabling conflicting applications and keeping your browser up to date can also improve performance and compatibility.

Avoiding Fake Trezor Bridge Software

Be cautious of fake downloads or unofficial websites offering Trezor Bridge installers. These may attempt to steal sensitive information.

Trezor will never ask you to enter your recovery seed into Trezor Bridge or any browser application. Any such request is a clear indicator of fraud.

Trezor Bridge plays a vital role in enabling secure communication between your Trezor hardware wallet and browser-based applications. By acting as a trusted connection layer, it ensures your private keys remain protected while delivering a smooth and reliable user experience.
