Trezor Bridge – What It Is and How It Works

Trezor Bridge is a vital piece of software that enables communication between your Trezor hardware wallet and your computer's browser. Developed by SatoshiLabs, the creators of Trezor, this background service allows seamless and secure interaction with the Trezor Suite and other web-based wallet interfaces.

Trezor Bridge replaces older browser-based extensions and ensures a more stable and secure connection between your hardware wallet and your internet browser.

🔗 What Is Trezor Bridge?

Trezor Bridge is a middleware communication tool. When you plug in your Trezor device and access the Trezor Suite (or another compatible app), the browser itself cannot directly talk to the hardware device. That’s where Trezor Bridge comes in—it acts as a secure translator between your computer and your Trezor device.

It runs silently in the background and facilitates:

• Firmware updates
• Wallet authentication
• Transaction signing
• Data transfers between your Trezor and supported web apps

Without Trezor Bridge (or Trezor Suite Desktop), most browsers won’t recognize your hardware wallet.

🖥️ When Do You Need Trezor Bridge?

You need Trezor Bridge if:

• You’re using Trezor via a web browser (like Chrome or Firefox)
• You choose not to install the desktop version of Trezor Suite
• You want to access your Trezor wallet via third-party services (like Web3 apps or portfolio trackers)

If you’re using the Trezor Suite desktop app, you don’t need Bridge, as the app includes direct USB support.
