Secure Communication Between Your Browser and Trezor Device
Trezor Bridge is a background communication service that enables smooth and secure interaction between your Trezor hardware wallet and supported web applications. It replaces older browser plugin systems with a more reliable and secure architecture designed for modern operating systems.
When you connect your Trezor device, Bridge acts as a translator between your browser and the hardware wallet, ensuring commands and confirmations are transmitted correctly without exposing private keys or sensitive data.
Obtain the installation package compatible with your operating system (Windows, macOS, or Linux).
Run the installer and follow system prompts. Administrative permission may be required.
Close and reopen your browser after installation so the Bridge service can be detected.
Attach your Trezor hardware wallet via USB and open a supported wallet interface.
Trezor Bridge creates a local communication channel between your computer and browser. When a web wallet sends a request (like signing a transaction), Bridge forwards that request to your device. You then verify and approve the action directly on the Trezor screen.
This structure ensures sensitive cryptographic operations never leave the hardware wallet, protecting you from browser-based attacks and malicious scripts.
Trezor Bridge is an essential part of the Trezor ecosystem, enabling secure browser-based wallet access without compromising the core principle of hardware isolation. By ensuring your device and applications communicate safely, Bridge helps maintain the integrity of your digital asset management workflow.
