Trezor Bridge is a dedicated, secure communication layer that connects your Trezor hardware wallet to supported web applications, enabling seamless and safe data exchange between your device and browser.
Overview
- Runs as a background service on your computer, facilitating reliable connectivity without frequent permission prompts.
- Acts as a universal connector for browsers and operating systems, unlike direct WebUSB communication which may suffer compatibility issues.
- Enables encrypted transmission of all commands, transaction data, and cryptographic operations to maintain maximum security.
- Essential for users who prefer third-party wallet integrations or web-based access without installing the full Trezor Suite.
Benefits
- Seamless Compatibility: Supports Chrome, Firefox, and other major browsers across multiple OS platforms.
- Enhanced Security: Ensures your private keys never leave the hardware wallet; only authorized commands pass through.
- Automatic Device Detection: Instantly recognizes your connected Trezor devices for quick actions.
- Reduced User Interaction: Runs silently without the need for manual driver installs or browser extensions.
How It Works
After installing Trezor Bridge, it runs continuously in the background as a local server on your PC. When a web app needs to interact with your Trezor device, Bridge securely relays messages between them.
Compared to WebUSB which requires repeated user permissions and has compatibility gaps, Bridge offers a smoother, more secure, and widely compatible connection experience.
Troubleshooting Tips
- If your device isn’t detected, try restarting your Trezor and computer, then refresh your browser.
- Disable firewalls or antivirus temporarily if installation issues arise.
- Ensure you have the latest Trezor Bridge version downloaded from the official site.
