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 bridge, allowing your Trezor device to interact with web-based cryptocurrency applications and wallets without compromising security.
Unlike browser extensions, Trezor Bridge runs as a standalone application in the background, ensuring that your private keys never leave your Trezor device while still providing a seamless user experience for managing your cryptocurrencies.

How Trezor Bridge Works
Trezor Bridge establishes a secure local connection between your hardware wallet and web applications:
- When you connect your Trezor device, Bridge detects it automatically
- Web applications communicate with Bridge through a secure local API
- Bridge forwards transaction details to your Trezor for verification
- You physically confirm transactions on your Trezor device
- Signed transactions are sent back to the web application via Bridge
This process ensures that sensitive operations always require physical confirmation on your Trezor device, protecting your assets even if your computer is compromised.
