What is Trezor Bridge?

Trezor Bridge is a lightweight communication tool that acts as a secure bridge between your Trezor hardware wallet and your web browser. If you use a Trezor device (like Trezor Model One or Model T), you need this software to let your browser-based Trezor Suite or other supported wallets interact with your hardware securely.

Originally, Trezor used a browser extension called “Trezor Chrome Extension” for this communication. But with time, web security standards changed, and the extension became outdated. Trezor Bridge replaced it, providing a more robust, faster, and more secure connection.

Trezor Bridge works silently in the background on Windows, macOS, and Linux. Once installed, it automatically detects when you connect your Trezor device and lets supported apps securely access it.

Why Do You Need Trezor Bridge?

Without Bridge, your computer cannot talk to your Trezor wallet. Bridge ensures:

• Encrypted, direct communication with your device.
• Improved security compared to browser extensions.
• Compatibility with modern browsers (Chrome, Firefox, Edge).

If you’re using Trezor Suite as a desktop app, you don’t need Bridge, since the Suite app handles communication directly. But if you use Trezor Suite through a web browser (suite.trezor.io/web), you must have Trezor Bridge installed.
