Trezor Bridge Guide

Secure Connection for Your Trezor Hardware Wallet

Trezor Bridge is the official, lightweight software that enables secure communication between your Trezor hardware wallet and browser-based applications. Whether you're using Trezor Suite Web, managing wallets via dApps, or signing transactions, the Bridge ensures every operation is encrypted, authenticated, and reliable.

Why Trezor Bridge Matters

• Reliable Device Detection: Bridges browser USB restrictions so your Trezor can be recognized securely. :contentReference[oaicite:1]{index=1}
• Encrypted Communication: All browser-to-device commands are encrypted and passed through an isolated local channel. :contentReference[oaicite:2]{index=2}
• Cross-Platform Compatibility: Works with Chrome, Firefox, Edge, Brave across Windows, macOS, and Linux. :contentReference[oaicite:3]{index=3}
• Plugin-Free: Eliminates the need for browser plugins or extensions for smoother use. :contentReference[oaicite:4]{index=4}
• Open Source & Local Only: No data logging—Bridge runs locally, never sending anything off your device. :contentReference[oaicite:5]{index=5}

How Trezor Bridge Works

1. You install Bridge, which runs a local service (e.g., `trezord`) on your computer. :contentReference[oaicite:6]{index=6}
2. When you connect your Trezor, Bridge establishes a secure, encrypted tunnel to supported web apps. :contentReference[oaicite:7]{index=7}
3. Your browser communicates with the Bridge, which relays commands to the Trezor device only after your physical confirmation. :contentReference[oaicite:8]{index=8}
4. All sensitive operations (PIN, seed, transaction signing) happen on the device—keys never touch your computer. :contentReference[oaicite:9]{index=9}

Installation & Troubleshooting

Installation Steps

• Go to the official download page at trezor.io/bridge. :contentReference[oaicite:10]{index=10}
• Install Bridge on your OS: Windows, macOS, or Linux. :contentReference[oaicite:11]{index=11}
• Connect your Trezor; the browser should now detect it automatically. :contentReference[oaicite:12]{index=12}

Common Issues

• “Trezor bridge is not running” — often resolved by reinstalling or restarting the browser. :contentReference[oaicite:13]{index=13}
• Firewall or antivirus may block communication; check settings. :contentReference[oaicite:14]{index=14}
• Browser conflicts — MetaMask or Brave can behave differently; switching browser may help. :contentReference[oaicite:15]{index=15}
• Suite users don’t need Bridge; uninstalling it might resolve conflicts. :contentReference[oaicite:16]{index=16}
• Hidden wallet or passphrase issues—some advanced setups may only show in Suite. :contentReference[oaicite:17]{index=17}

Security & Best Practices

• Download Only from Official Sources: Avoid phishing; use only trezor.io/start or bridge page. :contentReference[oaicite:18]{index=18}
• Verify Device Prompts: Always confirm transactions on the hardware display—you’re protected even if Bridge is compromised. :contentReference[oaicite:19]{index=19}
• Bridge Does Not Store Keys: Sensitive data remains on-device; Bridge only relays messages. :contentReference[oaicite:20]{index=20}
• Prefer Trezor Suite Desktop: It avoids Bridge entirely for more streamlined security. :contentReference[oaicite:21]{index=21}

FAQ

• Do I need Bridge with Trezor Suite Desktop? No, it's built-in and doesn't require Bridge. :contentReference[oaicite:22]{index=22}
• Is Bridge safe? Absolutely—it's open-source, audited, and never logs data or accesses private keys. :contentReference[oaicite:23]{index=23}
• What if browsers detect no device? Reinstall Bridge, restart browser, or switch ports. :contentReference[oaicite:24]{index=24}
• Should I uninstall old Bridge? If it's causing issues or you're migrating to Suite, yes. :contentReference[oaicite:25]{index=25}
