Trezor Bridge®

Trezor Bridge® is the official communication layer that securely connects Trezor hardware wallets with supported web applications, ensuring seamless access without compromising private key security.

What Is Trezor Bridge?

Trezor Bridge® is background software developed by SatoshiLabs that enables web browsers to communicate safely with Trezor hardware wallets. It replaces older browser-based connection methods with a more stable, secure, and efficient system.

Rather than relying solely on browser extensions, Trezor Bridge operates at the system level, ensuring consistent device recognition and secure data transmission.

Why Trezor Bridge Is Important

Hardware wallets are designed to keep private keys offline. Trezor Bridge plays a critical role by allowing web applications to interact with the device without ever accessing sensitive cryptographic data.

Key Features of Trezor Bridge

Secure Communication

All communication between your Trezor device and web applications is encrypted and authenticated.

Background Operation

Runs silently in the background, activating automatically when a Trezor device is connected.

Cross-Platform Support

Available for Windows, macOS, and Linux operating systems.

Automatic Updates

Keeps compatibility with evolving browsers and security standards.

How Trezor Bridge Works

  1. User connects a Trezor hardware wallet via USB
  2. Trezor Bridge detects the device automatically
  3. Web application sends a request through Bridge
  4. User confirms actions directly on the hardware device
  5. Transaction is securely signed offline
Important: Your private keys never leave the Trezor hardware wallet during this process.

Trezor Bridge vs Browser Extensions

While browser extensions can provide wallet connectivity, they are limited by browser security policies and updates. Trezor Bridge offers a more reliable alternative by operating independently of browser constraints.

Compatibility and Supported Platforms

Trezor Bridge supports all major desktop operating systems and works with popular browsers used to access Trezor Suite and third-party applications.

Common Issues and Troubleshooting

Device Not Detected

Ensure Trezor Bridge is installed and running, and that the USB cable is functioning correctly.

Browser Connection Errors

Restart the browser or reconnect the Trezor device to refresh the communication session.

Outdated Software

Keeping both Trezor Bridge and Trezor firmware updated improves stability and security.

Best Security Practices

Conclusion

Trezor Bridge® is a critical component of the Trezor ecosystem, providing secure, stable, and efficient communication between hardware wallets and web applications. By operating quietly in the background, it enhances usability while preserving the strict security model that Trezor is known for.

For users who rely on web-based crypto tools, Trezor Bridge ensures smooth connectivity without sacrificing safety or privacy.
