Trezor Bridge – Secure Communication Between Your Wallet and Browser

Trezor Bridge is an essential background service that allows your Trezor hardware wallet to communicate securely with web browsers and supported applications. It acts as a trusted connection layer between your physical device and online wallet interfaces, ensuring that all data exchanges remain protected and verified.

For users who prefer web-based access to their Trezor wallet rather than a desktop application, Trezor Bridge plays a critical role in maintaining security without sacrificing convenience.

What Is Trezor Bridge?

Trezor Bridge is a lightweight software component installed on your computer that enables browser-based wallet interactions with Trezor hardware devices. Modern web browsers no longer support direct USB communication with hardware wallets, and Trezor Bridge solves this limitation by acting as a secure intermediary.

Once installed, Trezor Bridge runs quietly in the background and automatically detects your connected Trezor device when you access compatible web wallets or services.

Why Trezor Bridge Is Important

Without Trezor Bridge, your browser would be unable to recognize or communicate with your Trezor hardware wallet. This service ensures:

• Secure USB communication between device and browser
• Verified interaction with supported web applications
• Protection against unauthorized access
• Reliable performance across operating systems

Trezor Bridge is especially useful for users who rely on browser-based crypto services instead of desktop software.

How Trezor Bridge Works

Trezor Bridge functions as a local service installed on your system. When you connect your Trezor device:

1. The Bridge detects the hardware wallet via USB
2. It establishes a secure local connection
3. Browser-based wallet interfaces communicate with the device through the Bridge
4. All sensitive operations require confirmation on the Trezor device screen

At no point are private keys exposed or transferred outside the hardware wallet.

Trezor Bridge vs Trezor Suite

Many users ask whether Trezor Bridge is still necessary when using Trezor Suite.

• Trezor Suite Desktop: Does NOT require Trezor Bridge
• Web Wallets and Browser Apps: Require Trezor Bridge

Trezor Suite includes built-in device communication, while browser-based access depends on Trezor Bridge to function correctly.
