Trezor Bridge: Secure Communication for Trezor Wallets

What Is Trezor Bridge?

Trezor developed Trezor Bridge to enable secure communication between Trezor hardware wallets and supported web browsers or applications.

Trezor Bridge works as a background service that allows your browser to recognize and communicate with your Trezor device through a secure USB connection.

It replaced older browser extensions and improved compatibility with modern browsers such as:

• Google Chrome

• Mozilla Firefox

• Microsoft Edge

• Brave Browser

Why Trezor Bridge Is Important

Browsers cannot directly communicate with hardware wallets without additional support software. Trezor Bridge acts as the secure communication layer between:

• Your computer browser

• Trezor Suite

• Third-party crypto applications

• Your Trezor hardware wallet

This ensures encrypted communication while keeping private keys safely stored offline on the hardware device.

Main Features of Trezor Bridge

Secure Device Communication

Bridge creates a secure encrypted channel between the wallet and browser.

Lightweight Background Service

The software runs quietly in the background after installation.

Cross-Platform Compatibility

Supported operating systems include:

• Windows

• macOS

• Linux

Improved Browser Support

Bridge works with most modern browsers and Web3-compatible platforms.
