Trézor Bridge®

Trézor Bridge® is the secure communication layer that connects your Trézor® hardware wallet to your desktop browser. Whether you're managing crypto assets, verifying addresses, or signing transactions, Trézor Bridge ensures your device communicates safely and seamlessly with supported applications.

🔌 What is Trézor Bridge®?

Trézor Bridge is a background service that allows your Trézor device to interact with your web browser via USB. It runs quietly on your computer and acts as a local messenger between your device and the Trézor Suite Web interface or third-party apps.

Without it, your browser wouldn’t be able to detect or talk to your hardware wallet. Bridge ensures a smooth, secure, and encrypted connection — without exposing your sensitive data to the internet or any browser-based vulnerabilities.

⚙️ Why Do You Need Trézor Bridge?

Browsers like Chrome, Firefox, or Brave no longer allow direct USB access for security reasons. Trézor Bridge solves this by running locally and facilitating encrypted communication between your browser and your hardware wallet.

Whether you’re accessing Trézor Suite Web, authenticating login requests, or using decentralized apps (DApps), Trézor Bridge makes sure everything works as intended — securely, efficiently, and reliably.

🛠 Installing Trézor Bridge

Getting started is simple:

1. Visit trezor.io/bridge
2. Choose your operating system (Windows, macOS, Linux)
3. Download and install the Bridge
4. Restart your browser (important!)
5. Connect your Trézor® device via USB

Once installed, Bridge runs in the background and requires no further action unless you manually disable or uninstall it.

🔐 Is Trézor Bridge Safe?

Absolutely. Bridge is developed and maintained by SatoshiLabs — the creators of Trézor®. It’s fully open-source, regularly audited, and designed with privacy and safety at the core.

Your private keys never leave the device, and Bridge itself does not transmit or store sensitive data. It only facilitates the connection between your browser and your device in a trusted, isolated environment.

🧠 Troubleshooting Tips

- After installation, always restart your browser.
- Ensure no other wallet apps are interfering with USB access.
- Use a high-quality USB cable and avoid hubs when possible.
- Check that your OS recognizes the device under USB settings.
- If issues persist, visit trezor.io/support.
