Trezor Bridge:

Trezor Bridge is a communication tool developed by SatoshiLabs that acts as a secure interface between your Trezor hardware wallet and supported web browsers. It allows the Trezor device to interact with platforms like the Trezor Suite or other third-party services that integrate Trezor's API. Without Trezor Bridge, your hardware wallet cannot communicate with your browser reliably, especially when using Chrome, Firefox, or Edge.

What Is Trezor Bridge?

Trezor Bridge is a lightweight background application installed on your computer. It runs silently and automatically detects any connected Trezor devices. Once installed, it facilitates a secure connection between your Trezor and the Trezor Suite app or web interface. It eliminates the need for outdated browser extensions and is considered more stable and secure.

Why Is It Necessary?

When you plug your Trezor device into your computer, your operating system doesn’t inherently know what to do with it. Trezor Bridge acts as the translator. It handles the secure exchange of data between the web app and the device, allowing features like authentication, transaction signing, account management, and more.

Installing Trezor Bridge

1. Visit https://trezor.io/bridge
2. Download the version compatible with your operating system (Windows, macOS, or Linux).
3. Install the application and follow on-screen instructions.
4. Restart your browser once installation is complete.
5. Connect your Trezor device and go to Trezor Suite to get started.

After successful installation, Bridge runs in the background automatically every time you use your Trezor.

Benefits of Trezor Bridge

• Improved compatibility across all modern browsers.
• Eliminates the need for browser plugins/extensions.
• Regular updates from SatoshiLabs ensure security patches and feature improvements.
• Secure communication channel with cryptographic protections.

Common Issues & Troubleshooting

Sometimes the device might not be detected, especially if multiple Trezor apps or browser extensions are running simultaneously. Ensure only one interface (e.g., Trezor Suite) is open and restart your browser or computer. Also, ensure you are running the latest version of Trezor Bridge.
