Overview
Trezor Bridge is a bridge application that allows communication between your Trezor hardware wallet and your web browser or Trezor Suite. Unlike direct USB connection, Trezor Bridge runs in the background and provides a secure channel for sending commands and receiving responses from your device. It ensures smooth integration with all supported operating systems and keeps your private keys offline at all times.
The software supports multiple browsers including Chrome, Firefox, Edge, and Brave, and works seamlessly across Windows, macOS, and Linux. Using Trezor Bridge is crucial for users who prefer browser-based access or want to manage cryptocurrencies directly via Trezor Suite.
Installation
Follow these steps to install Trezor Bridge safely:
Step 1: Download
Always download Trezor Bridge from the official source: trezor.io/bridge. Avoid third-party websites to prevent downloading malicious software.
Step 2: Install on Your OS
- Windows: Run the downloaded .exe file and follow the installation wizard. Windows SmartScreen may display warnings; confirm the publisher is SatoshiLabs.
- macOS: Open the .dmg file, drag Trezor Bridge to Applications, and approve security prompts if necessary.
- Linux: Use the provided .deb, .rpm, or AppImage files. Ensure you grant executable permissions for AppImage:
chmod +x TrezorBridge.AppImage.
Step 3: Verify Installation
After installation, Trezor Bridge usually runs in the background. You can check status by navigating to http://127.0.0.1:21325 in your browser. This confirms the bridge is running and ready to communicate with Trezor Suite or web apps.
Configuration
Trezor Bridge generally works out-of-the-box without special configuration. However, advanced users may want to configure settings for firewall exceptions or USB permissions.
Firewall & Security Settings
Ensure your firewall allows Trezor Bridge to communicate on localhost (127.0.0.1) and no external connections. The software never transmits data over the internet, only between your computer and the device.
Browser Configuration
Most modern browsers detect Trezor Bridge automatically. If your browser fails to connect, check for multiple Trezor applications or conflicts and restart your browser.
Security Considerations
Trezor Bridge is designed to maintain high security standards. Your private keys remain on the hardware wallet, never exposed to the computer. However, following best practices enhances security:
- Download Trezor Bridge only from trezor.io.
- Keep your operating system and browser updated to patch vulnerabilities.
- Verify downloaded files’ checksums or signatures if provided.
- Ensure you use secure USB connections and avoid untrusted hubs.
- Always confirm transactions directly on the Trezor device.
Usage
Once installed, Trezor Bridge enables communication for various purposes:
Connecting Trezor Suite
Launch Trezor Suite. The app automatically detects Trezor Bridge and connects your hardware wallet. You can manage wallets, send and receive cryptocurrencies, and update firmware.
Browser Access
Some web wallets or crypto services support Trezor integration via Trezor Bridge. After connecting the device, authorize access and confirm actions directly on the device.
Firmware Updates
Firmware updates are performed through Trezor Bridge. The application ensures the device receives the update securely while keeping your seed offline.
Troubleshooting Common Issues

- Ensure Trezor Bridge is running (check
http://127.0.0.1:21325). - Use the original USB cable.

Bridge Update Required
Trezor Suite or the browser may indicate that the bridge needs an update. Download the latest version from the official site and reinstall.
