What is Trezor Bridge?
Trezor Bridge is a lightweight desktop service that lets your Trezor hardware wallet communicate safely with web-based wallet apps. It acts as a small, secure bridge between your browser and your device so you can send and sign transactions while keeping private keys offline.
Secure local connection
Bridge runs locally on your computer and only exposes a small, well-defined API to browser apps. It never leaves your machine.
Cross-platform
Available for Windows, macOS, and Linux — simple installers keep it updated and compatible with modern browsers.
Quiet and reliable
Runs in the background with minimal system footprint and provides stable communication for wallet operations.
