Trezor Bridge — Secure Your Hardware Wallet®

What is Trezor Bridge?

Trezor Bridge is a lightweight background software developed by SatoshiLabs to facilitate secure data transfer between your Trezor hardware wallet and the computer. It acts as a communication layer that ensures encrypted, direct, and authenticated interaction between the Trezor device and supported interfaces like Trezor Suite.

Unlike browser extensions or drivers, Trezor Bridge is more stable and universal. It provides better compatibility across browsers such as Chrome, Firefox, Edge, and Opera, ensuring consistent performance across different platforms (Windows, macOS, Linux).

Why You Need Trezor Bridge

• Secure communication: It ensures all data transfers between your computer and device are encrypted and verified.
• Automatic device detection: Enables your browser or desktop app to instantly recognize your Trezor hardware wallet.
• Stable connectivity: Reduces issues like “Device not recognized” or failed firmware updates.
• Cross-platform compatibility: Works smoothly on all major operating systems and browsers.
• Improved performance: Provides faster response and synchronization with Trezor Suite compared to browser extensions.

How to Install Trezor Bridge

1. Visit the official download page at trezor.io/start or trezor.io/bridge/.
2. Select your operating system (Windows, macOS, or Linux).
3. Download the installer package and follow on-screen instructions.
4. Once installation is complete, restart your browser to enable communication.
5. Connect your Trezor hardware wallet using the provided USB cable and open Trezor Suite or the web version.

After installation, Trezor Bridge will run automatically in the background every time your computer starts, ensuring your Trezor device is ready for secure communication.

How Trezor Bridge Works

Trezor Bridge functions as an intermediary that securely relays commands between your Trezor hardware wallet and any authorized software interface. It does this by establishing a local communication channel on your device. When you use Trezor Suite or a compatible wallet, the app connects through this local bridge, eliminating the need for third-party browser extensions or insecure plug-ins.

Since Trezor Bridge runs locally, your data never passes through external servers, maintaining full privacy and control of your digital assets. Only verified, signed requests can reach your hardware wallet, protecting it from malware and phishing attacks.

Trezor Bridge vs Browser Extension

Previously, older versions of Trezor used browser extensions for communication. However, extensions were often limited, less secure, and vulnerable to browser updates. Trezor Bridge replaced them to ensure a seamless, secure, and consistent experience. Unlike extensions, Trezor Bridge:

• Runs independently of the browser.
• Provides direct encrypted communication with your Trezor device.
• Offers better stability and universal browser support.
• Receives regular updates from official Trezor developers.

Maintaining Security and Privacy

Trezor Bridge is built with the same focus on transparency and security that defines the entire Trezor ecosystem. Its source code is open and verifiable, ensuring you can always confirm its legitimacy. To maintain your privacy and safety:

• Download Trezor Bridge only from the official Trezor website: https://trezor.io.
• Keep your software updated to the latest version.
• Never install “Trezor Bridge” from third-party websites or links shared in emails or social media.
• Use antivirus and system protection tools to avoid tampered installations.

Troubleshooting Common Issues

1. Trezor Not Detected

Ensure that Trezor Bridge is running. Reconnect your device and restart the browser or computer. If the issue persists, reinstall Trezor Bridge and verify USB drivers are up to date.

2. Bridge Installation Failed

Make sure you have administrator rights during installation. Temporarily disable antivirus software that may block the installer. Then re-run the official installer from trezor.io/bridge.

3. Conflicts with Older Extensions

If you previously used the old “Trezor Chrome Extension,” remove it before installing Trezor Bridge to avoid communication conflicts.

4. Browser Compatibility

Most modern browsers support Trezor Bridge, but ensure your browser is up to date. If issues occur, try switching browsers or using the Trezor Suite desktop app for direct connection.

Updating Trezor Bridge

Trezor Bridge automatically checks for updates, ensuring you always have the latest version installed. When a new update is available, it will prompt you to download and install it securely. Regular updates improve stability and maintain compatibility with new operating system versions and browser releases.

Advantages of Using Trezor Bridge

• Ensures encrypted, authenticated communication between Trezor and your computer.
• Eliminates browser extension vulnerabilities.
• Enables smooth operation with Trezor Suite and web wallets.
• Works silently in the background without manual configuration.
• Protects you against man-in-the-middle attacks or unauthorized data access.

Stay Safe with Trezor Bridge

Your Trezor device, combined with Trezor Bridge, creates a strong security ecosystem. Always confirm actions on your hardware wallet screen and never trust what you see only on your computer. The Bridge helps you manage crypto safely, but the final confirmation must always happen on your physical Trezor device.
