What is Trezor Bridge?
Trezor Bridge is a lightweight background service that enables secure communication between your Trezor hardware wallet and supported web browsers. It acts as a facilitator, allowing your browser to interact with your Trezor device without compromising security.
Trezor Bridge runs silently in the background and automatically starts when needed, ensuring your Trezor device is always ready to securely sign transactions and manage your cryptocurrency assets.
Unlike browser extensions, Trezor Bridge doesn't require manual updates or interfere with your browsing experience. It's designed to work seamlessly with the Trezor Suite web interface and other supported applications.

Security Features
Trezor Bridge is built with security as the primary focus, implementing multiple layers of protection:
Local Communication Only
All communication occurs locally between your browser and Trezor device, preventing exposure to external networks.
No Private Key Exposure
Private keys remain securely stored on your Trezor hardware wallet and are never transmitted through the bridge.
Automatic Verification
Each transaction requires physical confirmation on your Trezor device, preventing unauthorized operations.
Tamper Protection
Built-in mechanisms detect and prevent tampering attempts, ensuring the integrity of the communication channel.
How It Works
Trezor Bridge establishes a secure local connection between web applications and your Trezor hardware wallet:
Connection Process
When you access a Trezor-compatible web application, Trezor Bridge automatically detects the request and establishes a secure local connection to your device.
Transaction Signing
For cryptocurrency transactions, the details are sent to your Trezor device for verification. You physically confirm the transaction on your device's screen, and the signed transaction is returned to the web application.
Background Operation
Trezor Bridge runs as a background service, starting automatically when needed and remaining available for future interactions without requiring manual intervention.
