Trezor Bridge

Overview

Trezor Bridge is the official communication software developed by SatoshiLabs for connecting your Trezor hardware wallet with desktop and web applications such as Trezor Suite. It acts as a secure middleware between your computer and Trezor device, allowing you to manage your cryptocurrency safely and efficiently.

Installed on your computer, Trezor Bridge runs silently in the background, ensuring smooth communication between your wallet and browser-based services. It is lightweight, secure, and designed for all major operating systems — Windows, macOS, and Linux.

Without Trezor Bridge, your computer cannot properly detect or interact with the Trezor device, which means you won’t be able to send transactions or manage your digital assets through the Trezor Suite App or web applications.

What Is the Purpose of Trezor Bridge?

The primary purpose of Trezor Bridge is to establish a secure connection between your Trezor hardware wallet and supported software interfaces. Unlike browser plugins or outdated drivers, Trezor Bridge uses encrypted local communication channels, ensuring that your device interacts only with trusted, verified applications.

• Secure Communication: Trezor Bridge authenticates data exchange between your device and apps.
• Seamless Operation: Eliminates browser compatibility issues previously caused by plugins.
• Cross-Platform Support: Works on Windows, macOS, and Linux environments.
• Automatic Detection: Recognizes when your Trezor is connected and communicates instantly with Trezor Suite.
• Privacy-Oriented: No user data or cryptocurrency information is stored or transmitted.

Essentially, Trezor Bridge is the secure handshake between your hardware wallet and digital world, guaranteeing smooth performance and protection across all devices.

How to Install Trezor Bridge

Setting up Trezor Bridge is quick and easy. Follow these official steps to ensure a proper installation:

1. Visit the Official Website

Go to trezor.io/bridge to download the latest version of Trezor Bridge. Always use the official site to avoid fake or malicious software.

2. Choose Your Operating System

Select the version for your OS — Windows, macOS, or Linux. The download link will automatically detect your system and suggest the appropriate package.

3. Run the Installer

After downloading, open the installer and follow on-screen instructions. On macOS, you may need to authorize installation in System Preferences. On Linux, ensure you have administrative privileges.

4. Restart Your Browser or Computer

Once installation is complete, restart your browser (if using Trezor Suite Web) or your computer. Trezor Bridge runs in the background and starts automatically.

5. Connect Your Trezor Device

Plug in your Trezor hardware wallet. The Trezor Suite App or browser should now detect your device automatically, confirming that Trezor Bridge is functioning correctly.

Security and Privacy

Trezor Bridge has been built with security as its foundation. It ensures that communication between your hardware wallet and computer is authenticated, encrypted, and tamper-proof. Because all sensitive actions — such as signing transactions or verifying addresses — occur within the hardware device itself, your private keys remain 100% offline.

• Offline Key Storage: Private keys never leave your Trezor wallet.
• Local Communication: All data exchanges occur between your local machine and device, not external servers.
• Open Source: The entire codebase is publicly available, ensuring transparency and community trust.
• Regular Updates: Security improvements are rolled out regularly through official channels.
• Data Protection: Trezor Bridge does not log or track user information.

Together, these measures ensure that even if your computer is compromised, Trezor Bridge and your hardware wallet continue to protect your assets.

Troubleshooting and Common Issues

Occasionally, users may experience difficulties connecting their Trezor device even after installing Trezor Bridge. Below are common issues and how to fix them:

• Device Not Detected: Reconnect the device or restart Trezor Suite. Make sure Bridge is running in your background processes.
• Browser Connection Failed: Clear browser cache and ensure you’re using the latest version of Chrome or Firefox.
• Multiple Versions Installed: Uninstall any old or duplicate Trezor Bridge versions to avoid conflicts.
• Firewall Blocking Connection: Check your antivirus or firewall settings and whitelist Trezor Bridge.
• Linux USB Permissions: Add your user to the “plugdev” group or update udev rules using Trezor’s guide.
