Introduction
Trézór Bŕidge® acts as the lightweight connector between your Trezor hardware device and the Trézór™ Suite desktop or web app. It enables secure communication, firmware updates, and transaction signing while keeping keys isolated on the device. This section explains the role of Bridge and why it matters for a safe, user-friendly crypto experience.
What is Trezor Bridge?
Trezor Bridge is a platform-agnostic bridge application that runs locally on your computer. It translates web or desktop app calls into USB / HWP requests that the hardware device can safely handle. The Bridge improves compatibility across browsers and operating systems while offering the minimal surface area needed for secure operations.
Key Benefits
- Security: Private keys never leave the hardware device — Bridge only forwards signed requests.
- Compatibility: Works with Trézór™ Suite (desktop & web) to support many coins and firmware features.
- Seamless UX: Automatic device detection, simple firmware updates, and guided transaction flows.
- Cross-platform: Installs on Windows, macOS, and Linux with minimal user friction.
How it Works (Simple Flow)
- User opens Trézór™ Suite and connects hardware via USB.
- Suite sends a request to the locally running Bridge service.
- Bridge forwards the request to the connected hardware device using a secure protocol.
- User confirms actions on the hardware screen; device signs or approves operations.
- Signed transaction returns through Bridge to Suite and is broadcast to the network.
Security Considerations
Bridge is intentionally minimal — it does not access or store private keys. Users should always verify firmware authenticity, download Bridge only from official channels, and confirm transaction details on the device screen, not just in the Suite. Physical device confirmation is the last line of defence against remote attacks.
Best Practices
- Download Bridge and Suite from official Trezor domains.
- Keep firmware up to date and read release notes for changes.
- Use strong OS-level security, avoid public USB hubs, and verify certificate prompts.
Common Troubleshooting
If your device is not detected: check USB cable, restart Bridge, reinstall the latest Bridge version, or try another USB port. When in doubt, consult official support resources and community forums.
When to Contact Support
- Device fails firmware update repeatedly.
- Bridge installation errors that persist after reinstall.
- Unrecognized transaction prompts or unexpected device behaviour.
Conclusion
Trézór Bŕidge® is a small but critical component that makes the Trézór™ Suite experience reliable and secure. By keeping sensitive operations on-device and providing a stable communication layer, Bridge preserves both security and usability for everyday crypto management.
