What is Trezor Bridge?
Trezor Bridge is a lightweight 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 without compromising security.
Unlike browser extensions, Trezor Bridge runs as a standalone application in the background, providing a more stable and secure connection. It automatically detects when you connect your Trezor device and establishes a secure channel for data transmission.

How Trezor Bridge Works
Trezor Bridge creates a secure communication channel between your hardware wallet and web applications. When you connect your Trezor device to your computer, Bridge detects it and establishes a local connection.
Communication Flow
1. You connect your Trezor device to your computer via USB
2. Trezor Bridge detects the device and establishes a secure local connection
3. When you visit a Trezor-compatible web application, it communicates with Bridge
4. Bridge relays messages between the web application and your Trezor device
5. All sensitive operations (like signing transactions) happen securely on the Trezor device itself
Security Architecture
Trezor Bridge uses a carefully designed security model where private keys never leave your Trezor device. The Bridge only facilitates communication - all cryptographic operations and private key handling occur securely on the hardware wallet itself.
