What Is Trezor Bridge®?
Trezor Bridge® is an official lightweight background service by SatoshiLabs that securely communicates between your Trezor hardware wallet and supported web applications, like Trezor Suite in browser mode or compatible dApps. :contentReference[oaicite:1]{index=1}
Unlike older browser extensions or plugins, Bridge runs locally on your computer and facilitates encrypted USB and WebUSB communications without exposing your private keys. :contentReference[oaicite:2]{index=2}
How It Works: Behind the Scenes
