Overview of Trezor Bridge

Trezor Bridge runs silently in the background, creating a trusted communication channel between your Trezor device and your computer. This process allows desktop wallet apps or supported browsers to communicate with the device safely, without exposing sensitive keys to the network.

Benefits of using Trezor Bridge

  • Reliable communication across different operating systems.
  • Supports browsers lacking full WebUSB capabilities.
  • Officially signed software ensuring integrity.
  • Automatic background operation for seamless experience.
