Trezor Bridge — Connect Your Trezor to the Web Securely

Trezor Bridge is the official communication software that enables your browser to securely talk to your Trezor hardware wallet. Without it, most browsers cannot detect or communicate with your device reliably. :contentReference[oaicite:0]{index=0}

What Is Trezor Bridge?

Trezor Bridge is a lightweight background service developed by SatoshiLabs. It runs on your desktop and acts as a secure connector between your Trezor device and supported web wallets or applications. :contentReference[oaicite:1]{index=1}

🌟 Key Fact: Trezor Bridge never stores your private keys or seed phrase – all sensitive operations occur on your Trezor device itself. :contentReference[oaicite:2]{index=2}

How Trezor Bridge Works

Once installed, Trezor Bridge runs in the background and listens for connection requests from your browser to your Trezor device. It uses a local communication port to maintain a secure channel without exposing your wallet keys to the internet. :contentReference[oaicite:10]{index=10}

Communication Flow

  1. Your browser requests access to a Trezor device.
  2. Trezor Bridge relays the request securely via its local service interface.
  3. Bridge forwards the command to the Trezor device over USB.
  4. The device processes and confirms actions on-device.

This layered approach provides an extra security boundary between your online wallet interface and your Trezor hardware. :contentReference[oaicite:11]{index=11}

Step 2: Run the Installer

Compatibility & Support

Supported Browsers

Bridge does not currently support mobile browsers – mobile connections are handled by OTG or app-based methods. :contentReference[oaicite:16]{index=16}

Supported Operating Systems

Trezor deals natively with system-level USB interactions that most browsers block for safety, making Bridge necessary for broad browser compatibility. :contentReference[oaicite:17]{index=17}

Common Issues & Fixes

Problem: Bridge Not Detected

If your Trezor or browser indicates Bridge isn’t installed, ensure the service is running and your browser has permission. Restarting the OS can also help. :contentReference[oaicite:18]{index=18}

Problem: Device Not Recognized

Try using a different USB port or cable, and ensure Bridge is current. Clearing browser cache or trying another browser often resolves this. :contentReference[oaicite:19]{index=19}

Firewall/Antivirus Interference

Sometimes security tools block local services like Bridge. Temporarily whitelist Bridge in your firewall if necessary. :contentReference[oaicite:20]{index=20}

Bridge and Trezor Suite

The Bridge works with the Trezor Suite web interface to allow you to manage accounts, send and receive crypto, update firmware, and monitor your portfolio. It’s recommended to use both together for the most seamless experience. :contentReference[oaicite:21]{index=21}

Trezor Suite Web vs Desktop

The desktop Suite app integrates communication differently and may not require a separate Bridge install. However, the web suite does. :contentReference[oaicite:22]{index=22}
