Trezor Bridge

What Is Trezor Bridge?

Trezor Bridge is a background service that enables secure communication between your web browser and your Trezor hardware wallet. It is essential if you're using web-based apps like Trezor Suite Web or third-party crypto services that require Trezor interaction.

Without Trezor Bridge, your browser cannot detect or talk to your hardware wallet. It’s the “middleman” that connects your device to the internet in a secure, encrypted way.

Why Do You Need Trezor Bridge?

Modern browsers like Chrome, Firefox, or Edge restrict USB device access directly from the page. Trezor Bridge solves this by running locally and securely managing the communication. You need it for:

• Logging into Trezor Suite Web
• Connecting your Trezor to third-party wallets or exchanges
• Signing transactions from a web interface
• Updating firmware via browser

Think of it as the “driver” for your Trezor hardware device — without it, your browser can’t use Trezor properly.

Supported Operating Systems

Trezor Bridge is available for:

• Windows (7 and newer)
• macOS (High Sierra and newer)
• Linux (all major distributions)

Note: Some Linux systems may require additional permissions or udev rules for USB access.

How to Install Trezor Bridge

Installing Trezor Bridge is simple and takes just a minute:

1. Go to the official download page: https://trezor.io/bridge/
2. Choose your operating system and download the installer
3. Run the installer and follow the on-screen instructions
4. Once installed, restart your browser
5. Connect your Trezor and launch Trezor Suite Web

Trezor Bridge vs. Trezor Suite Desktop

If you use the Trezor Suite desktop app, you do not need Trezor Bridge. The desktop version includes all required drivers to communicate with your hardware wallet directly.

Use Trezor Bridge only if you’re using the browser version of Trezor Suite or third-party tools.

How Trezor Bridge Works (Simplified)

Trezor Bridge runs in the background on your computer as a lightweight service. When you open a supported website (like suite.trezor.io), it will automatically detect if Bridge is installed.

Once your Trezor is connected via USB, Bridge safely handles all communication, such as:

• Sending/receiving transaction data
• Requesting confirmation on the Trezor screen
• Performing cryptographic operations offline

This ensures your private keys never touch your browser or your computer.

Troubleshooting Common Issues

• Bridge not detected: Try restarting your browser or reinstalling Bridge
• USB not recognized: Use a different cable or port
• Linux users: Check that udev rules are correctly installed
• Antivirus blocking: Whitelist Bridge in your firewall/antivirus software

If problems persist, visit the Trezor Support Center.

Is Trezor Bridge Safe?

Yes. Trezor Bridge is developed and maintained by SatoshiLabs, the makers of Trezor. The code is open-source and has been audited by security professionals. It runs locally, does not store any data, and doesn’t connect to any server without user action.

Conclusion

Trezor Bridge is a vital tool for securely connecting your Trezor hardware wallet to your web browser. Whether you're using Trezor Suite Web or other crypto apps, Bridge ensures that your communication is safe, private, and reliable.
