Trezor Bridge — Secure

Trežor™ Bridge® — Secure local communications

Trezor Bridge is a local communication layer that allows secure interaction between your Trezor hardware wallet and desktop or browser applications. Instead of exposing the device directly to every web app, Bridge centralizes access on localhost and helps maintain a consistent security model.

Install and run

Download from trezor.io/bridge. Run the installer and ensure the background process is allowed by your OS firewall. Then open Trezor Suite or a web app that supports Bridge.

Diagnostics

If the device is not discovered, open Task Manager or Activity Monitor to see whether Bridge process is running. Check browser console messages for blocked requests and enable WebUSB if needed.

Best practice

Only accept connection prompts you initiated. Confirm every transaction on your Trezor device screen. Use the official Suite for firmware updates.
