What is Trezor Bridge®?
Trezor Bridge is an official communication tool developed by Trezor (SatoshiLabs) that allows your hardware wallet to securely interface with your web browser and desktop applications.
Without the Bridge, your browser cannot directly detect or communicate with your hardware wallet — meaning wallet apps like Trezor Suite won’t function properly.
Key functions of Trezor Bridge:
Establishes a secure, encrypted connection between your Trezor device and computer
Allows Trezor Suite to detect your device instantly
Enables firmware updates
Lets you manage crypto transactions
Works across major browsers and operating systems
Provides more consistent performance than browser-only communication
In short, Trezor Bridge is the backbone of the Trezor ecosystem, enabling seamless hardware wallet use.
