Trezor Bridge makes it simple and secure to connect your Trezor hardware wallet to your computer and the web. Use Trezor Bridge, Trezor/Bridge or trezor bridge to enable safe, local communication between your device and wallet apps.
What is Trezor Bridge?
Trezor Bridge (often written as Trezor Bridge, Trezor/Bridge or trezor bridge) is a small, lightweight application that runs on your computer and acts as a secure bridge between your Trezor hardware wallet and browser-based wallet applications or native wallet clients. Without Trezor Bridge, many browsers cannot directly communicate with the hardware device. Installing trezor bridge ensures reliable USB communication, secure messaging, and a seamless user experience when managing private keys and signing transactions.
Keywords: trezor bridge, Trezor/Bridge, Trezor Bridge — included intentionally for search and discovery.
Why use Trezor Bridge?
Secure local communication: Trezor Bridge ensures encrypted, device-level communication between your computer and hardware wallet.
Browser compatibility: Many browsers require a bridge like Trezor Bridge or Trezor/Bridge to talk to USB devices securely.
Ease of use: Once installed, trezor bridge runs quietly in the background and automatically handles requests from wallet interfaces.
Official support: Trezor Bridge is the officially recommended connector for Trezor devices and is updated periodically for security and compatibility.
How to install and use Trezor Bridge
To begin, download the Trezor Bridge installer for your operating system and follow the setup instructions. After installation, connect your Trezor device via USB and open your preferred wallet interface. The bridge (trezor bridge or Trezor/Bridge) will detect your device and prompt for authorization. You will confirm operations directly on your hardware wallet to keep private keys safe on the device itself.
Typical steps:
Download the Trezor Bridge installer for Windows, macOS, or Linux.
Run the installer and grant necessary permissions.
Connect your Trezor hardware wallet via USB.
Open the wallet interface (web or native). The Trezor Bridge will connect automatically.
Confirm any transaction or action on your device's screen.
Again: trezor bridge, Trezor/Bridge, and Trezor Bridge are the terms you may see used interchangeably.
Security considerations
Security is the core design of Trezor Bridge. The bridge never has access to your private keys — those remain on the hardware device. Trezor Bridge only relays messages between your computer and the Trezor. Always download Trezor Bridge from the official source and verify checksums where provided. Keep both your Trezor device firmware and the Trezor Bridge application up to date to mitigate vulnerabilities.
Best practices:
Install Trezor Bridge only from official resources.
Verify installer signatures or checksums if available.
Confirm every transaction on your Trezor device screen—never approve blind requests.
Use a secure, up-to-date browser or native wallet that supports Trezor/Bridge.
Troubleshooting common issues
If your trezor bridge or Trezor/Bridge isn't connecting, try these simple steps: ensure the device is unlocked and connected, restart the bridge service, reinstall the Trezor Bridge app, try a different USB cable or port, and check that no other application is blocking USB access. If problems persist, consult official support resources for detailed debugging. Remember that using the correct and updated version of Trezor Bridge is often the simplest fix.
