Comprehensive Overview
Trezor Bridge is the official desktop connector for Trezor hardware wallets, ensuring secure communication between your device and wallet applications. It acts as a local intermediary that never exposes your private keys to the network, giving you safe and reliable access across platforms.
Why Use Trezor Bridge?
- Compatibility with all modern operating systems: Windows, macOS, Linux.
- Fallback for browsers without WebUSB support.
- Cryptographically signed builds to ensure integrity.
- Runs in the background unobtrusively, simplifying the user experience.
Step-by-Step Installation
Download Official Bridge
Visit trezor.io/start and select your OS. Verify checksums if provided for security.
Install & Launch
Follow on-screen instructions. Administrator permissions may be required. The service starts automatically after installation.
Connect Trezor Device
Use a high-quality USB cable. Launch your wallet interface and follow device prompts.
Confirm Operations
All transactions or account actions require physical confirmation on your device.
Advanced Configuration & Tips
- Adjust logging and debugging via configuration files for troubleshooting.
- Use ephemeral sessions for developer integrations to avoid persistent sensitive access.
- Bridge only listens on the local machine; never expose ports externally.
- Keep OS and Bridge updated for maximum security.
Detailed Troubleshooting
Bridge Not Detected
- Ensure Bridge service is running in background processes.
- Restart the service and wallet application.
- Switch USB ports or use direct motherboard ports instead of hubs.
Firewall or Antivirus Interference
Add exceptions for local loopback communication. Never forward Bridge ports to public networks.
Developer Integration Notes
Always follow official API documentation. Confirm sensitive actions physically on the device. Never store recovery seeds on the host machine.
