What is Trezor Bridge?
Trezor Bridge is a background communication service that allows your web browser to interact securely with your Trezor hardware wallet. Instead of relying on browser extensions, Bridge provides a direct, encrypted channel between your device and supported applications.
It plays a critical role in enabling safe cryptocurrency transactions while reducing exposure to malicious plugins or phishing tools.
Official Source
Always download Bridge from the official page: trezor.io/bridge. Installing from unofficial sources can expose you to serious security risks.
Why It Matters
Bridge ensures your browser never directly handles sensitive cryptographic data. All private key operations stay inside the Trezor device, while Bridge simply acts as a messenger between interfaces.
How It Works
When you connect your wallet and visit supported apps, Bridge detects your device and establishes secure communication. Transactions are prepared on your computer but signed only within the hardware wallet after on-device verification.
Installation Steps
1. Visit the official Bridge page.
2. Download the version for your operating system.
3. Install and run the background service.
4. Restart your browser.
5. Connect your Trezor device and confirm detection.
Compatibility
Trezor Bridge supports major browsers and operating systems. It ensures smooth integration with the setup process at Trezor.io/start.
Security Benefits
By removing dependency on browser extensions, Bridge reduces attack surfaces. It protects against phishing scripts, malicious popups, and extension-based exploits. The device screen remains your final verification checkpoint.
Best Practices
Keep Bridge updated, download only from official sources, and never share your recovery phrase. For help, visit Trezor Support.
