Trezor Bridge® — Secure Connection Between Your Browser and Trezor Wallet
Trezor Bridge is a communication tool developed by Trezor that allows your web browser to securely connect with a Trezor hardware wallet. It acts as a bridge between the Trezor device and web applications like Trezor Suite or supported crypto services, enabling safe interaction without exposing private keys to the internet.
Trezor Bridge is essential for users who want reliable browser-based access to their hardware wallet features.
What Is Trezor Bridge?
Trezor Bridge is a lightweight background service that enables secure communication between:
Your Trezor hardware wallet
Your web browser
Crypto management applications (like Trezor Suite Web)
Supported devices include:
Trezor Model One
Trezor Model T
Trezor Safe 3
It ensures your browser can recognize and interact with your hardware wallet safely.
What Does Trezor Bridge Do?
Trezor Bridge enables:
Secure device detection in browsers
Transaction communication between wallet and web apps
Signing transactions safely on the hardware device
Access to Trezor Suite Web
Compatibility with supported crypto services
Importantly, it does NOT store private keys or wallet data.
Why Trezor Bridge Is Needed
Modern browsers often restrict direct hardware access for security reasons. Trezor Bridge solves this by:
Providing a secure communication layer
Allowing stable wallet connection across browsers
Ensuring compatibility with updated web security standards
Without Trezor Bridge (or similar communication tools), browsers may not detect the hardware wallet properly.
