What is Trezor Bridge?
Trezor Bridge is a small local application that enables secure communication between your Trezor device and web-based wallet interfaces.
Quick install
- Download: Get the installer from the official Trezor website or trusted sources. Look for the Trezor Bridge download specific to your OS.
- Install: Run the installer and follow on-screen prompts. On macOS, you may need to allow the app in System Preferences > Security & Privacy.
- Run Bridge: After installation, Trezor Bridge runs in the background and listens locally. It typically appears as a small tray/icon app.
- Connect device: Plug your Trezor into a USB port and open your browser to the wallet web app. The site will communicate via Trezor Bridge to the device.
- Allow access: When prompted by your browser and device, confirm the connection directly on your Trezor hardware.
Troubleshooting
- If your browser doesn’t detect the device: restart Trezor Bridge and your browser.
- Check that no other apps are blocking USB access; temporarily disable antivirus if it interferes.
- On Linux, ensure you have the correct udev rules and permissions to access USB devices.
- If Bridge won’t install, download the latest installer and try again or consult official support.
Security notes
Only download Trezor Bridge from official sources. Never enter your recovery seed into any software. Always confirm the website's domain and the device screen before approving transactions.

Developers: Trezor Bridge runs a local HTTP API. Use the official libraries when integrating to ensure compatibility and security. Avoid direct raw communication unless necessary.
