Trezor Bridge: Secure Web Communication with Your Trezor Wallet

What is Trezor Bridge?

Trezor Bridge is a communication tool that enables seamless interaction between your Trezor hardware wallet and supported web browsers. It acts as a bridge between the Trezor device and web-based applications, allowing users to manage cryptocurrencies, sign transactions, and use decentralized applications (dApps) securely without installing browser extensions.

Why Use Trezor Bridge?

Many modern browsers have deprecated native USB access from web pages, making direct communication with hardware wallets more challenging. Trezor Bridge solves this by providing a background service that manages secure device communication via a local server running on your machine.

• ✅ Works without browser extensions
• ✅ More secure than direct web access
• ✅ Auto-starts with your system
• ✅ Compatible with all major operating systems

How Trezor Bridge Works

When you connect your Trezor device and open a supported Trezor web app, the site communicates with Trezor Bridge running on your computer. Trezor Bridge handles all device requests and signs operations securely through your hardware wallet.

Trezor Bridge listens on a local port (usually 127.0.0.1:21325) and acts as a relay between your browser and the Trezor device via USB.

Supported Devices and Browsers

Supported Devices:

• Trezor Model One
• Trezor Model T

• Microsoft Edge

How to Install Trezor Bridge

1. Visit the Trezor Start page.
2. Choose your device model and follow the setup instructions.
3. Click on "Install Bridge" to download the latest version for your OS.
4. Run the installer and follow on-screen steps to complete installation.
5. Restart your browser and connect your Trezor device.

Note: On macOS and Linux, you may need to allow permissions for the USB device.

Troubleshooting Common Issues

• Browser can’t detect Trezor: Ensure Trezor Bridge is running in the background. Restart your browser if needed.
• USB device not recognized: Try a different USB port or cable, and ensure the device firmware is updated.
• Firewall blocking access: Make sure 127.0.0.1:21325 is accessible and not blocked by antivirus software.

Security Considerations

Trezor Bridge is designed with security in mind. It does not store private keys or sensitive data. All operations like transaction signing happen on the device itself, making it extremely resistant to malware or phishing attacks.

Always download Trezor Bridge from official sources and ensure you're not using outdated or modified versions.

Conclusion

Trezor Bridge is an essential tool for anyone using a Trezor hardware wallet with web-based apps. It ensures a smooth, secure, and user-friendly experience while maintaining the highest levels of security. Whether you’re sending crypto, signing messages, or accessing dApps, Trezor Bridge makes the process seamless.
