Trezor Bridge® — Secure Communication Between Your Device and Browser

Trezor Bridge® is a lightweight background service that enables secure communication between your Trezor® hardware wallet and supported web browsers. It acts as a connector, allowing your device to interact safely with browser-based applications like Trezor Suite Web and other trusted crypto platforms.

If you are using Trezor through a browser instead of the desktop app, Trezor Bridge ensures your device is recognized and functions properly.

What Is Trezor Bridge?

Trezor Bridge is software installed on your computer that creates a secure channel between your Trezor hardware wallet and your web browser. Modern browsers restrict direct USB communication for security reasons, and Trezor Bridge solves this by handling device communication in the background.

It runs silently after installation and does not require manual operation.

Why Is Trezor Bridge Important?

When using web-based wallet interfaces, your Trezor device must:

• Be securely detected by your browser
• Communicate transaction data safely
• Verify operations through encrypted channels

Trezor Bridge enables all of this while keeping your private keys securely stored offline on your hardware wallet.

For users completing initial device setup, the process typically begins at Trezor.io/start, where firmware installation and wallet configuration are guided step-by-step. During this process, you may be prompted to install Trezor Bridge if you're using the web version of Trezor Suite.

When Do You Need Trezor Bridge?

You need Trezor Bridge if:

• You are using Trezor Suite Web instead of the desktop version
• Your browser does not detect your Trezor device
• You are accessing third-party web applications that integrate Trezor

If you are using the Trezor Suite desktop application, Trezor Bridge is generally not required because the desktop app communicates directly with your device.

How to Install Trezor Bridge

1. Visit the official Trezor setup page.
2. Navigate to the downloads section.
3. Select Trezor Bridge for your operating system (Windows, macOS, or Linux).
4. Download and install the package.
5. Restart your browser after installation.

For security reasons, always download Bridge from the official source, typically linked during setup at Trezor.io/start. Never install software from unofficial websites.

Security and Privacy

Trezor Bridge is designed with strong security standards:

• Encrypted local communication
• No storage of private keys
• No access to your recovery seed
• No external data sharing

All sensitive actions — such as signing transactions — still require confirmation directly on your Trezor device screen. Bridge simply facilitates communication; it does not control or store your crypto assets.

Troubleshooting Trezor Bridge

If your device is not detected:

• Ensure Trezor Bridge is installed and running
• Try restarting your browser
• Reconnect the USB cable
• Restart your computer if necessary
• Check for firmware updates via Trezor.io/start

Keeping your firmware and Trezor software updated helps avoid compatibility issues.

Trezor Bridge vs Trezor Suite Desktop

For the most secure and stable experience, many users prefer the desktop version of Trezor Suite. However, Trezor Bridge remains essential for smooth browser-based operation.

Final Thoughts

Trezor Bridge® plays a key role in connecting your Trezor hardware wallet to browser applications safely and efficiently. While it works quietly in the background, it ensures secure communication without compromising your private keys.

For best results, always start your device setup and download official tools from Trezor.io/start to maintain the highest level of crypto security.
