Trezor Bridge – Communication Between Trezor and Your Browser

What Is Trezor Bridge?

Trezor Bridge is a small, lightweight communication software developed by SatoshiLabs. It enables your Trezor hardware wallet to communicate with supported browsers, allowing you to manage your crypto assets securely from your computer.

When you plug your Trezor device into your computer, the browser alone cannot directly communicate with the device. This is where Trezor Bridge comes in—it acts as a secure middleware that enables data exchange between your browser and Trezor hardware.

Why Do You Need Trezor Bridge?

Direct USB communication is not natively supported by all browsers.
Trezor Bridge provides a stable communication channel for wallet apps.
Allows Trezor Suite Web and third-party apps to detect and use your Trezor device.
Works silently in the background once installed.

🔐 Note: If you're using Trezor Suite Desktop, you don't need Bridge. It's only required for Web Suite or third-party browser-based wallets.
