Trezor Bridge® | Connect Your Trezor to Web Browsers

Hardware wallets are designed to isolate private keys from the internet, but they still need a safe way to communicate with applications. Trezor Bridge provides that secure connection, ensuring seamless interaction between Trezor devices and supported web platforms without compromising security.

Understanding the Role of Trezor Bridge

Trezor Bridge is a small background service that allows web browsers to recognize and communicate with Trezor hardware wallets. It was introduced to replace older browser plugins, which became unreliable and insecure as browser technologies evolved.

Today, Trezor Bridge is the recommended solution for users who access Trezor through web-based interfaces.

Security-Focused Architecture

One of the key strengths of Trezor Bridge is its security-first design. The Bridge does not store private keys, transaction data, or recovery phrases. Instead, it simply enables communication between the browser and the device.

All sensitive actions, such as confirming transactions or changing security settings, must be approved directly on the Trezor hardware wallet. This ensures that even if a computer is compromised, attackers cannot access funds without physical device confirmation.

When Do You Need Trezor Bridge?

Trezor Bridge is primarily required when:

• Using Trezor Suite in a web browser
• Accessing third-party wallet interfaces that support Trezor
• Browsers do not natively support direct USB communication

Users of the Trezor Suite desktop app typically do not need Trezor Bridge, as the desktop app handles device communication internally.

Common Issues and Troubleshooting

If your Trezor device is not detected, ensuring that Trezor Bridge is installed and up to date often resolves the issue. Restarting the browser or reconnecting the device can also help.

Conclusion

Trezor Bridge is an essential yet often overlooked component of the Trezor ecosystem. By enabling secure communication between hardware wallets and web interfaces, it ensures usability without sacrificing security. For users who prefer browser-based access to their crypto assets, Trezor Bridge remains a reliable and trusted solution.
