Trezor Bridge is a lightweight software that acts as a secure communication layer between your Trezor hardware wallet and your web browser. It enables your browser-based applications to detect and communicate with the Trezor device without exposing sensitive data to the internet.
When you plug in your Trezor device, Trezor Bridge runs quietly in the background and manages communication between the browser and your hardware wallet. Unlike browser extensions, Bridge runs as a standalone application, making it more secure and less prone to browser compatibility issues.
