Trezor Bridge | Official Connection Software for Trezor Wallets

Trezor Bridge is the official background service that enables secure communication between your Trezor hardware wallet and applications such as Trezor Suite or browser extensions. It ensures your wallet connects safely to your desktop or web interface without exposing private keys or sensitive data.

⚠️ Important Security Notice: Only download Trezor Bridge from the official source — trezor.io/start or wallet.trezor.io. Never install from third-party or unofficial sites.

What is Trezor Bridge?

Trezor Bridge is a lightweight background program that acts as a secure communication channel between your Trezor device and the software on your computer. It replaces the older “Trezor Chrome Extension” and is now the default connection method used by Trezor Suite and web wallets.

Without Trezor Bridge, your device may not be detected by browsers or desktop apps, making it essential for performing any transaction or firmware update.

Key Benefits of Trezor Bridge

✅ Establishes secure and encrypted communication between your device and computer.
✅ Replaces outdated browser plugins (like the Chrome extension).
✅ Automatically detects your Trezor when connected.
✅ Compatible with Trezor Suite, browser wallets, and third-party apps.
✅ Supports both Trezor Model One and Trezor Model T.

How Trezor Bridge Works

When you connect your Trezor to a computer, Trezor Bridge runs silently in the background, allowing the Trezor Suite app or browser wallet to communicate securely with your hardware wallet. All communication happens through encrypted channels, and your private keys never leave the Trezor device.

🔒 Your private keys remain offline. Even if your PC is compromised, the Bridge ensures all signing actions happen on your Trezor device only.

Troubleshooting Trezor Bridge

1. Trezor Not Detected

If your device isn’t recognized:

Ensure Trezor Bridge is installed and running in the background.
Try reconnecting your device using a different USB port or cable.
Restart your browser or system.
For Linux users, make sure udev rules are properly configured.

2. Reinstalling the Bridge

If the Bridge is corrupted or outdated, uninstall it first, then download the latest version from trezor.io/start. Always restart your computer after reinstallation.

Trezor Bridge and Trezor Suite

Trezor Bridge is an essential part of the Trezor Suite ecosystem. When you launch Suite for the first time, it automatically checks if Bridge is installed. If not, it prompts you to install it for secure communication. Once installed, your wallet can seamlessly connect to your device for managing crypto, performing firmware updates, and verifying transactions.

Security Recommendations

Always verify the URL before downloading: only use trezor.io domains.
Never share your recovery seed or PIN.
Keep your operating system and Trezor Suite up to date.
Avoid using public or shared computers to manage your crypto.
