Frequently Asked Questions

Trezor Bridge is communication software that enables your web browser to interact with your Trezor hardware wallet. It creates a secure local connection between browser-based wallet interfaces and your physical device, allowing you to manage cryptocurrency transactions while keeping your private keys safely stored on the hardware wallet.

Yes, Trezor Bridge is completely safe. It never has access to your private keys, which remain securely stored in your Trezor device. The software is open-source, meaning the code is publicly available for security audits. All communication between your browser and device is encrypted, and regular security audits ensure the software maintains the highest standards.

Trezor Bridge supports Windows 7 and later, macOS 10.11 and newer (including Apple Silicon M1/M2 processors), and Linux distributions with kernel 3.10 or higher. Packages are available for popular distributions including Debian, Ubuntu, Fedora, and others.

First, try restarting your computer. If the issue persists, completely uninstall Bridge, restart again, and reinstall the latest version. Check that your firewall or antivirus isn't blocking the application. On some systems, you may need to manually restart the Bridge service after updates.

The Bridge itself is currency-agnostic—it simply facilitates communication between your device and wallet applications that support specific cryptocurrencies.

Trezor Bridge operates entirely on your local computer and doesn't require an internet connection to function. However, you will need internet access to connect to blockchain networks for viewing balances and broadcasting transactions. The Bridge service itself runs locally on localhost:21325.
