Trezor Bridge® Guide — Official Tool for Wallet Access

Welcome to the complete **Trezor Bridge® Guide** — your trusted resource for understanding, installing, configuring, and securely using the official connectivity tool that enables your Trezor hardware wallet to communicate with web applications and wallets. This guide covers everything from basics to advanced troubleshooting.

1. Introduction: What Is Trezor Bridge®?

Trezor Bridge® is the **official communication interface** developed by SatoshiLabs that acts as a secure local gateway between your Trezor hardware wallet and supported applications (including browser-based wallets and desktop apps). :contentReference[oaicite:1]{index=1}

⚠️ Always download Trezor Bridge® only from the official source: 👉 https://trezor.io/bridge/ (official download page) — this ensures you avoid phishing and malicious installers. :contentReference[oaicite:2]{index=2}

Unlike legacy browser plugins, Trezor Bridge® runs as a small background service on your computer, communicating locally (using localhost) to maintain a secure connection. :contentReference[oaicite:3]{index=3}

2. Why You Need Trezor Bridge®

2.1 Secure Communication

Trezor Bridge® ensures all communication with your hardware wallet stays encrypted and local, preventing external attacks from accessing your wallet communication channel. :contentReference[oaicite:4]{index=4}

2.2 Cross-Platform Compatibility

Bridge works seamlessly on Windows, macOS, and Linux, providing a consistent connection method across operating systems and browsers. :contentReference[oaicite:5]{index=5}

2.3 Browser and Wallet Support

Many modern browsers (Chrome, Firefox, Edge, Safari) and third-party wallets rely on Bridge to detect and pair with Trezor devices. :contentReference[oaicite:6]{index=6}

2.4 Preserve Private Key Security

Bridge never accesses your private keys — all signing operations occur directly on the hardware wallet itself. This design ensures maximum security. :contentReference[oaicite:7]{index=7}

5. How Trezor Bridge® Works (Technical Overview)

5.1 Local Service Model

Bridge runs as a background service that listens on your computer’s local interface (e.g., localhost). Web apps communicate with this service to send commands to the connected hardware wallet. :contentReference[oaicite:12]{index=12}

5.2 Secure Message Flow

When a wallet interface requests a transaction or an account scan, Bridge forwards the command locally via an encrypted tunnel, and your Trezor device displays information for confirmation. :contentReference[oaicite:13]{index=13}

5.3 No External Data Transfer

All operations remain local — Bridge does not expose any data to the internet. This prevents remote tampering or malicious access. :contentReference[oaicite:14]{index=14}

6. Troubleshooting Common Issues

6.1 Bridge Not Detecting Device

• Make sure Bridge is running in the background.
• Restart your browser and computer.
• Try a different USB cable or port. :contentReference[oaicite:15]{index=15}

6.2 “No Device Found” Errors

• Ensure you have installed the official Bridge from trezor.io/bridge. :contentReference[oaicite:16]{index=16}

6.3 Firewall / Security Software Blocking Bridge

Allow Bridge in your OS firewall settings to enable local communication. :contentReference[oaicite:17]{index=17}

6.4 Browser Compatibility

Use supported browsers like Chrome, Firefox, or Edge to ensure proper Bridge detection. :contentReference[oaicite:18]{index=18}

7. Security Best Practices

7.1 Keep Software Updated

Ensure you update Trezor Bridge, Trezor Suite, and your Trezor firmware regularly. :contentReference[oaicite:19]{index=19}

7.2 Confirm Actions on Device

Always review and confirm any transaction details directly on the Trezor screen — never rely only on the computer display. :contentReference[oaicite:20]{index=20}

7.3 Avoid Unofficial Downloads

Download Bridge only from official links and avoid third-party mirrors. :contentReference[oaicite:21]{index=21}

8. Developer Integration & API

Developers building applications that communicate with Trezor devices can leverage Bridge’s API to enumerate devices, open secure sessions, and request actions. Bridge’s open-source nature also allows developers to audit the protocol. :contentReference[oaicite:22]{index=22}
