What is Trezor Bridge?
Trezor Bridge is a background service that enables secure communication between your Trezor hardware wallet (Trezor One or Trezor Model T) and web browsers or desktop applications. It acts as a translator between USB protocols and web APIs, allowing your device to interact with web interfaces like wallet.trezor.io and third-party applications.

Current Status (2025)
Important Update: As of February 2025, the standalone Trezor Bridge has been deprecated and its functionality is now fully integrated into Trezor Suite. New users should install Trezor Suite instead of the standalone Bridge.
The transition to integrated Bridge functionality in Trezor Suite offers several advantages:
- Simplified installation process
- Automatic updates with Suite
- Improved performance and reliability
- Reduced potential for conflicts
Installation Guide
For New Users
- Visit Trezor.io/start
- Download and install Trezor Suite for your operating system
- Follow the setup wizard (Bridge functionality is included automatically)
- Connect your Trezor device when prompted
For Legacy Users with Standalone Bridge

Technical Details
How Trezor Bridge Works
Trezor Bridge creates a secure communication channel between:
- Your Trezor hardware wallet (via USB)
- Web browsers (through WebUSB API)
- Desktop applications (via local sockets)
This architecture ensures that:

- All operations require physical confirmation
- Communication is encrypted end-to-end
Supported Platforms
- Windows: 10 and 11 (64-bit)
- macOS: 10.15 Catalina and newer

Note: Mobile devices (iOS/Android) are not supported by Trezor Bridge. For mobile access, use the official Trezor Suite mobile app (Android only) with an OTG adapter.
