Trezor Bridge — Secure Wallet Connection™

Overview

What is Trezor Bridge? (H3)

Trezor Bridge was a lightweight background service that allowed web apps and desktop software to communicate with Trezor hardware wallets over a local HTTP API. It enabled older browser integrations and some third-party wallets to access device functionality when WebUSB or direct integration wasn't available.

Current status & recommendation

Important: Trezor has deprecated the standalone Trezor Bridge and recommends using the official Trezor Suite (desktop or web) and WebUSB integrations for the best, most secure experience. If you still run standalone Bridge, follow official uninstall/upgrade guidance per Trezor's documentation. :contentReference[oaicite:1]{index=1}

How it worked (technical summary)

The Bridge runs as a local HTTP server (commonly visible as a process called trezord), listening on a local port. Web pages or desktop apps communicate with it via HTTP endpoints; the Bridge then proxies commands to Trezor devices over USB. While useful historically, modern WebUSB support reduces the need for a standalone proxy.

Security & best practices

Never share sensitive info

Never disclose your recovery seed, PIN, or passphrase to any website or person. Use official downloads only and verify signatures where provided. If using Bridge or Suite, obtain installers from official Trezor domains or GitHub releases. :contentReference[oaicite:2]{index=2}

When to use Bridge vs Suite/WebUSB

• Use Trezor Suite desktop or the Suite web app (WebUSB) for most users — best support and maintained builds. :contentReference[oaicite:3]{index=3}
• Use standalone Bridge only if a specific legacy workflow requires it and you verify the source — otherwise avoid it (deprecated). :contentReference[oaicite:4]{index=4}

Troubleshooting highlights

Common issues (H5)

• Bridge process not running — check your OS task list for trezord and ensure firewall isn't blocking the local port. :contentReference[oaicite:5]{index=5}
• Connection failures with third-party wallets — confirm firmware and Suite/Bridge versions; consult Trezor forum threads for community solutions. :contentReference[oaicite:6]{index=6}

Actionable checklist

1. Download Trezor Suite from the official site and prefer Suite/WebUSB where possible. :contentReference[oaicite:7]{index=7}
2. Uninstall standalone Bridge if present (follow Trezor's uninstall guide). :contentReference[oaicite:8]{index=8}
3. Keep device firmware up to date and verify installers. :contentReference[oaicite:9]{index=9}
4. Ask for help via official support and community forum if unsure. :contentReference[oaicite:10]{index=10}
