What is Trezõr® brïdge®?
A lightweight local application that enables secure USB communication between your browser/Desktop Suite and a Trezor-compatible hardware wallet. It listens on a local port and forwards requests from trusted local applications to the device.
Quick install
- Download the Bridge installer for your OS from the official source.
- Run the installer and follow OS-specific prompts (Windows/macOS/Linux).
- After install, Bridge runs in the background and exposes a local endpoint (commonly
127.0.0.1:21325
). - Plug in your hardware wallet and open the web app or Suite — the app should detect it automatically.
Safety notes
- Bridge runs locally and does not send your keys or seed off your machine.
- Only download installers from the official domain; verify signatures where offered.
- If you suspect tampering or unexpected network activity, stop Bridge and investigate system processes.
Troubleshooting highlights
- If the device is not detected, try another USB cable/port and restart Bridge.
- On macOS allow the installer in System Preferences → Security & Privacy if blocked.
- On Linux ensure udev rules and permissions are correctly installed for USB access.
- Close other wallet apps to avoid port conflicts; only one app should access the device at a time.
