What is Trezor Bridge?
Trezor Bridge is a lightweight software that acts as a communication interface between your Trezor hardware wallet and supported web browsers. When you use wallet interfaces like Trezor Suite (web version) or third-party applications, Trezor Bridge ensures that data can be securely transmitted between the browser and your hardware wallet.
Most modern browsers no longer support direct USB communication for security reasons. Trezor Bridge solves this limitation by providing a background service that allows web-based wallet interfaces to detect and communicate with your Trezor device in a secure and user-friendly manner.
Why Do You Need Trezor Bridge?
Trezor Bridge is essential if you're using the Trezor web interface on a browser like Chrome, Firefox, Brave, or Edge. Without it, your browser will not recognize your Trezor device, preventing you from managing your assets online.
- 🧩 Browser Compatibility: Enables secure communication on browsers that don’t support WebUSB.
- 🔐 Security Layer: Handles device communication locally, preventing exposure to untrusted networks.
- 🖥️ System Integration: Works on Windows, macOS, and Linux with minimal configuration.
- ⚙️ Automatic Detection: Your device is detected automatically once connected via USB.

How Trezor Bridge Works
Once installed, Trezor Bridge runs as a background service on your operating system. When you connect your Trezor hardware wallet via USB, Bridge communicates with it and passes the relevant information to supported apps or web interfaces.
This allows Trezor Suite Web (and other apps) to access your device’s information, sign transactions, verify addresses, and update firmware — all while keeping your private keys safely inside the hardware device.
Security Considerations
- Local Communication: Trezor Bridge does not transmit data over the internet. All actions are local.
- Open Source: The source code is available on GitHub for transparency and auditing.
- Trusted by SatoshiLabs: Officially maintained and signed by the creators of Trezor.
For maximum security, always verify the digital signature of downloaded installers and never share your recovery seed or PIN.
