Trezor Bridge — Connect Your Trezor to Web Browsers

Trezor Bridge is the lightweight software that enables secure communication between your Trezor hardware wallet and web applications running in modern browsers. It acts as a trusted bridge so you can interact with wallets, exchanges, and dApps without exposing your private keys.

Why Trezor Bridge is important

Hardware wallets like Trezor store private keys offline to protect them from malware and phishing. To sign transactions or manage accounts from a browser, a secure local channel is required. Trezor Bridge provides that channel — it sits on your computer, translates browser requests into a format your device understands, and ensures that interactions happen only when you physically approve them on the Trezor device.

Core features

• Secure device communication: End-to-end connection between browser, Bridge, and your Trezor device.
• Cross-platform support: Available for Windows, macOS and Linux.
• Browser compatibility: Works with Chromium-based browsers and Firefox.
• Automatic updates: Bridge can check for and install updates to keep compatibility and security current.
• Small footprint: A lightweight background application designed to minimize resource use.

How to install and use

1. Download: Visit the official Trezor website and download Trezor Bridge for your operating system. Always download from the official source to avoid tampered software.

2. Install: Run the installer and follow on-screen instructions. On macOS you may need to allow the app in Security & Privacy settings.

3. Connect your Trezor: Use a USB cable to connect the device. Open your browser and navigate to your chosen wallet interface (for example, Trezor Suite or supported third-party web wallets).

4. Authorize: When a web app needs to sign a transaction or access account info, the Trezor device will prompt you to confirm the action physically — this step prevents remote attacks from initiating transactions without your consent.

Security best practices

• Always download Bridge from the official Trezor site and verify checksums when provided.
• Keep your device firmware and Bridge app up to date to receive security patches and new features.
• Never enter your recovery seed into a computer or browser — only into the Trezor device when prompted during setup.
• Use a strong, unique passphrase if you enable the passphrase feature; treat it as a separate, critical secret.

Troubleshooting tips

If your browser doesn't recognize the Trezor device, try the following steps:

• Restart Trezor Bridge and your browser.
• Try a different USB cable or port — some cables only supply power and not data.
• Temporarily disable conflicting browser extensions or software that may block USB access.
• Reinstall Bridge if problems persist and reboot your computer.

Compatibility & integrations

Trezor Bridge is designed to work with the official Trezor ecosystem as well as popular third-party wallets and services that adopt the WebUSB or Bridge APIs. It enables a wide range of cryptographic operations while keeping your keys isolated on the hardware device.

Conclusion

Trezor Bridge is a critical component for anyone using a Trezor hardware wallet with web-based interfaces. It balances usability and security by allowing seamless browser interactions while maintaining device-level confirmations for every sensitive action. Installing and keeping Bridge up to date helps ensure smooth and safe management of your crypto assets.
