Trezor Bridge is the official communication tool that allows your Trezor hardware wallet to connect securely with Trezor Suite and supported browsers. This lightweight application is essential for managing cryptocurrencies safely on desktop devices.
What Is Trezor Bridge?
Trezor Bridge functions as a background service that enables secure data exchange between your computer and Trezor device. It ensures encrypted communication without exposing private keys, making it a core component of the Trezor security ecosystem.
The Bridge replaces older browser extensions that were discontinued for security reasons. It supports both Trezor Model One and Trezor Model T.
