Trézór Bridge®™ | Smooth, Safe, and Encrypted Crypto Connectivity

Trezor Bridge is a background service that enables secure communication between your Trezor hardware wallet and web-based applications. It acts as a trusted link between your device and supported browsers, ensuring that data exchanged during wallet operations remains protected. For users who interact with web wallets or third-party services, Trezor Bridge plays a vital role in maintaining both functionality and security.

Although Trezor Suite now includes built-in connectivity, Trezor Bridge remains important for browser-based access and compatibility with certain platforms.

What Is Trezor Bridge?

Trezor Bridge is lightweight software installed on your computer that allows web browsers to detect and communicate with your Trezor hardware wallet. Browsers cannot directly interact with USB hardware for security reasons, so Trezor Bridge serves as the approved communication layer.

It ensures that:

  • Your Trezor device is recognized by the browser
  • Commands are securely passed to the device
  • Sensitive data remains protected
  • Only authorized actions are executed on the hardware wallet

Why Trezor Bridge Is Important

Trezor Bridge enables users to access their wallet through supported web interfaces without compromising security. It prevents malicious websites from directly controlling the hardware wallet by enforcing strict communication rules.

Key benefits include:

  • Secure USB communication
  • Protection against unauthorized browser access
  • Compatibility with multiple web platforms
  • Automatic background operation

Without Trezor Bridge, many browser-based wallet features would not function properly.

When Do You Need Trezor Bridge?

You typically need Trezor Bridge when:

  • Accessing your wallet through a web interface
  • Using browser-based crypto services that support Trezor
  • Interacting with older wallet platforms or third-party tools
  • Browsers do not support direct device communication

If you use only the desktop version of Trezor Suite, you may not need Trezor Bridge, as connectivity is already integrated.

Installing Trezor Bridge

Step 1: Download the Software

Download Trezor Bridge from the official Trezor website. Always verify the source to avoid malicious versions.

Step 2: Install on Your System

Trezor Bridge supports major operating systems, including:

  • Windows
  • macOS
  • Linux

Follow the installation instructions provided for your operating system.

Step 3: Restart Your Browser

After installation, restart your browser to allow it to recognize the Trezor Bridge service.

Once installed, Trezor Bridge runs quietly in the background and requires no further configuration.

How Trezor Bridge Works

When you connect your Trezor device:

  1. The browser sends a request through Trezor Bridge
  2. Trezor Bridge securely forwards the request to the device
  3. The device asks for physical confirmation
  4. Approved actions are executed only after user consent

This layered approach ensures that even if a browser or website is compromised, unauthorized actions cannot be completed without device confirmation.

Security Features of Trezor Bridge

Trezor Bridge follows strict security principles to protect users:

Device Isolation

Private keys never leave the hardware wallet, regardless of browser activity.

Authenticated Requests

Only valid, recognized commands are forwarded to the device.

Open-Source Transparency

Trezor Bridge is open source, allowing independent security audits.

No Data Storage

The bridge does not store private data, passwords, or recovery seeds.

These features make Trezor Bridge a safe and reliable communication tool.

Trezor Bridge vs Trezor Suite Connectivity

While both serve similar purposes, they are used in different scenarios:

  • Trezor Suite: Recommended for everyday use, offering built-in communication and advanced features.
  • Trezor Bridge: Required for web-based access and third-party browser tools.

For maximum security and ease of use, Trezor recommends Trezor Suite whenever possible.
