Trezor Bridge

A secure communication layer that connects Trezor hardware wallets with web and desktop applications. Trezor Bridge ensures smooth interaction while keeping private keys safely isolated inside your device.

What Is Trezor Bridge?

Trezor Bridge is a background service that enables trusted communication between a Trezor hardware wallet and supported applications running in your browser or on your computer. It acts as a secure translator, allowing software to send requests to the device and receive verified responses—without ever exposing sensitive data.

By separating wallet communication from browsers and applications, Trezor Bridge reduces attack surfaces and improves overall system reliability.

Why Trezor Bridge Is Important

Modern browsers limit direct access to USB devices for security reasons. Trezor Bridge solves this challenge by providing a dedicated local service that safely manages hardware connections.

Stable Device Connectivity

Maintains a consistent connection between your Trezor device and applications, preventing unexpected disconnects or compatibility issues.

Improved Security Isolation

Applications never communicate with the hardware wallet directly. All requests pass through Trezor Bridge for controlled handling.

Cross-Platform Support

Designed to work across major operating systems, ensuring a uniform experience regardless of your setup.

How Trezor Bridge Works

Once installed, Trezor Bridge runs silently in the background. When a supported website or application needs to interact with your hardware wallet, it sends a request to the local Bridge service.

At no point do private keys leave the hardware wallet. Trezor Bridge only transmits public information and signed responses approved on the device itself.

Security Model

Trezor Bridge follows a strict security model that prioritizes user consent and hardware verification. All critical actions require physical approval, protecting users even if their computer or browser environment is compromised.

Combined with PIN protection, optional passphrases, and open-source transparency, Trezor Bridge strengthens the overall security posture of the Trezor ecosystem.

Who Needs Trezor Bridge?

Trezor Bridge is essential for users who interact with their hardware wallet through web interfaces or third-party applications that rely on secure device communication.

Conclusion

Trezor Bridge plays a critical role in the hardware wallet ecosystem. By enabling secure, reliable communication between devices and applications, it allows users to manage their digital assets with confidence.

With its invisible operation, strong isolation principles, and focus on safety, Trezor Bridge ensures that convenience never comes at the cost of security.
