Trezor developed Trezor Bridge to enable secure communication between Trezor hardware wallets and supported web browsers or applications.
Trezor Bridge works as a background service that allows your browser to recognize and communicate with your Trezor device through a secure USB connection.
It replaced older browser extensions and improved compatibility with modern browsers such as:
Google Chrome
Mozilla Firefox
Microsoft Edge
Brave Browser
Browsers cannot directly communicate with hardware wallets without additional support software. Trezor Bridge acts as the secure communication layer between:
Your computer browser
Trezor Suite
Third-party crypto applications
Your Trezor hardware wallet
This ensures encrypted communication while keeping private keys safely stored offline on the hardware device.
Bridge creates a secure encrypted channel between the wallet and browser.
The software runs quietly in the background after installation.
Supported operating systems include:
Windows
macOS
Linux
Bridge works with most modern browsers and Web3-compatible platforms.
Download only from the official Trezor website:
Trezor Bridge Official Download
Choose the version compatible with your operating system.
Follow the installation instructions on your screen.
After installation, restart your browser to enable proper device communication.
Attach your Trezor wallet via USB and open:
Trezor Suite
Supported browser wallets
Compatible crypto services
You may need Trezor Bridge if:
Your browser cannot detect the Trezor device
You use browser-based wallet integrations
You connect Trezor to third-party Web3 platforms
You use the web version of Trezor Suite
Desktop versions of Trezor Suite often include built-in communication support, reducing the need for separate Bridge installation.
Try:
Another USB cable
Different USB port
Restarting your browser
Reinstalling Trezor Bridge
Chrome and Edge generally provide the best compatibility.
You may need to approve the application under:
System Settings
Privacy & Security
Private keys remain inside the hardware wallet and never leave the device.
All transactions must still be confirmed physically on the Trezor screen.
Hardware confirmation helps reduce phishing risks and malicious browser attacks.
Download Bridge only from official Trezor websites
Never share your recovery seed phrase
Keep your firmware and software updated
Verify transaction details directly on the hardware wallet
Trezor Bridge is an essential utility for many browser-based Trezor workflows. It improves device detection, browser compatibility, and secure communication while maintaining strong hardware wallet security.
For the safest crypto experience, always combine Trezor Bridge with official Trezor software and secure offline backup practices.
