Trezor Bridge — Secure Your Hardware Wallet®
Trezor Bridge is an essential communication layer between your Trezor hardware wallet and your computer. It ensures that your device connects securely to the official Trezor Suite app, enabling smooth and safe management of your cryptocurrency assets. With Trezor Bridge, every transaction and authentication step happens through verified, encrypted channels — keeping your private keys safe at all times.
What Is Trezor Bridge?
Trezor Bridge is a lightweight software application developed by SatoshiLabs that allows your Trezor device to communicate with supported browsers and desktop applications. It acts as a secure middle layer, verifying that connections are legitimate and ensuring all data exchanges remain private and protected from malicious interference.
Unlike browser plugins or drivers, Trezor Bridge runs silently in the background, establishing a direct and secure link between your wallet and the Trezor Suite interface. It eliminates compatibility issues, improves stability, and enhances the user experience across operating systems.
Why You Need Trezor Bridge
Trezor Bridge is required for your device to communicate with Trezor Suite if you’re not using the standalone desktop app. Modern browsers often restrict USB access for security reasons, and Trezor Bridge safely bypasses these limitations by providing a verified connection layer.
- Secure communication: Trezor Bridge encrypts and validates every request between your hardware wallet and computer.
- Automatic detection: It allows Trezor Suite to instantly recognize your connected device.
- Cross-platform support: Works on Windows, macOS, and Linux systems without requiring extra browser extensions.
- Trusted source: Developed and digitally signed by Trezor.io, ensuring authenticity and security.

Updating Trezor Bridge
Keeping Trezor Bridge updated is essential for maintaining compatibility and ensuring continued secure communication between your device and Trezor Suite. Updates include performance enhancements, security patches, and bug fixes. When an update is available, Trezor Suite will automatically prompt you to install it. You can also manually download the latest version from trezor.io/bridge.

Security Advantages of Trezor Bridge
Security is at the heart of Trezor Bridge. Every communication between your Trezor hardware wallet and your computer is protected using cryptographic verification. This ensures that your wallet is only interacting with the authentic Trezor Suite and not with any unauthorized software or web pages.

- Verified communication: Ensures that your Trezor connects only to legitimate Trezor services.

Troubleshooting Common Issues
1. Trezor Not Detected
Make sure Trezor Bridge is installed correctly. Try restarting your computer and browser. If the issue persists, reinstall Trezor Bridge or connect your device using a different USB cable or port.

Why Trezor Bridge Matters
Trezor Bridge is a core component of the Trezor ecosystem, ensuring your hardware wallet communicates safely with your computer. Without it, Trezor Suite would not be able to securely exchange data with your device. By using Trezor Bridge, you are adding an invisible yet powerful security layer that keeps your crypto protected from malware, browser exploits, and phishing attacks.
