What is Trezor Bridge?
Trezor Bridge is a background service that enables secure communication between your Trezor hardware wallet and web browsers. It acts as a facilitator, allowing your Trezor device to interact with web-based applications like the Trezor Wallet interface and other compatible services.
Unlike browser extensions, Trezor Bridge runs as a standalone application in the background, providing a more stable and secure connection. It automatically detects when a Trezor device is connected and facilitates the communication between the device and supported web applications.

How Trezor Bridge Works
Trezor Bridge creates a secure communication layer between web applications and your Trezor hardware wallet. When you connect your Trezor device to your computer, the Bridge service:
- Detects the connected Trezor device
- Establishes a secure communication channel
- Translates requests from web applications into commands the device understands
- Returns signed transactions and other data to the web application
This architecture ensures that sensitive operations like private key generation and transaction signing always occur on the secure element of your Trezor device, never exposing your keys to the computer or internet.

Security Architecture
Trezor Bridge is designed with security as a primary consideration. Its architecture includes multiple layers of protection:
Isolated Communication
The Bridge creates an isolated communication channel that prevents malicious websites from directly interacting with your Trezor device. All communication must pass through the Bridge's security checks.
Certificate Pinning
Trezor Bridge uses certificate pinning to ensure it only communicates with legitimate Trezor services, preventing man-in-the-middle attacks.
Minimal Privileges
The service operates with minimal system privileges, reducing the potential impact of any security vulnerabilities.
Automatic Updates
Trezor Bridge includes an automatic update mechanism to ensure you always have the latest security patches and features.
