Trezor Bridge® | Connect Your Trezor to Web Browsers

Securely connect your Trezor hardware wallet to supported browsers and apps using Trezor Bridge.

🔗 What is Trezor Bridge®?

Trezor Bridge® is a lightweight software application that enables secure communication between your Trezor hardware wallet and your computer’s web browser. It acts as a middle layer, ensuring your browser or crypto app can detect and interact with your Trezor device without compromising your private keys.

This bridge is vital for platforms like Trezor Suite and other crypto services that integrate with Trezor. Without it, browsers can’t recognize your connected hardware wallet.

⚙️ How Does Trezor Bridge Work?

Secure Communication

Trezor Bridge uses local communication between your Trezor device and your browser. It never transmits your private data online. All signing and decryption operations happen inside your Trezor device, which keeps your crypto assets safe even when interacting with the internet.

Browser Compatibility

Trezor Bridge works seamlessly with major browsers like Chrome, Firefox, Edge, and Brave. It ensures consistent connectivity, especially when WebUSB (native USB communication) is not available or supported.

🛡️ Security Benefits of Trezor Bridge

1. End-to-End Encryption

Communication between your wallet and browser is encrypted locally. Sensitive data like seed phrases never leave your device.

Why Trezor Suite Needs Bridge

The Trezor Suite application relies on Bridge to detect and manage Trezor devices when accessed via browsers. It’s the key communication channel that allows you to perform crypto transactions directly from your PC.

Browser Access Setup
