Introduction to Trezor Bridge

Trezor Bridge is an essential software tool that allows your Trezor hardware wallet to communicate with web applications, including Trezor Suite Web. Acting as a secure communication layer, it ensures your browser can detect and interact with your Trezor device while maintaining security and privacy.

If you use Trezor via a browser instead of the standalone desktop application, installing Trezor Bridge is required. This lightweight background service bridges the gap between your physical Trezor device and the browser interface.

What Does Trezor Bridge Do?

Trezor Bridge enables seamless interaction between your hardware wallet and the web environment. Without it, browsers lack native support to detect and connect to USB hardware wallets like Trezor.

Trezor Bridge is required for browser-based wallet access, signing transactions, and using decentralized applications (dApps) that rely on Trezor authentication.

Why You Need Trezor Bridge

While the Trezor Suite Desktop App can directly communicate with your hardware wallet, the web version needs help to communicate over USB. This is where Trezor Bridge comes in. It eliminates the need for browser extensions, minimizes connection errors, and ensures compatibility across multiple platforms.

Note: Trezor Bridge is required only for web-based interactions. You do not need it if you’re using the desktop version of Trezor Suite.
