Trezor Bridge® is a lightweight software utility developed by SatoshiLabs that enables secure communication between your Trezor Hardware Wallet and supported web browsers. Acting as the connection layer between your computer and the wallet interface, Trezor Bridge ensures that your browser can safely interact with your Trezor device without exposing sensitive information. It is an essential component for users who want to manage their crypto assets through web-based wallets like Trezor Suite in browser mode.
Trezor Bridge was designed to replace the older Chrome and Firefox browser extensions, which became obsolete due to evolving browser security standards. It operates as a background service that securely connects your Trezor device to your browser via USB. Once installed, it automatically detects your device and allows you to interact with supported cryptocurrency applications directly in your web browser.
Unlike traditional extensions, Trezor Bridge provides better performance, improved compatibility, and enhanced reliability across different operating systems — including Windows, macOS, and Linux.
Without Trezor Bridge, your web browser cannot communicate with your Trezor device, meaning you would not be able to verify transactions, manage your accounts, or sign operations securely. The Bridge ensures that data exchanged between your browser and hardware wallet is encrypted and authenticated, preventing unauthorized access and man-in-the-middle attacks.
The application runs locally on your system, ensuring that your private keys never leave your Trezor device. Every transaction still requires manual confirmation on the hardware wallet screen, maintaining maximum security.
The installation process takes only a few minutes, and once complete, Trezor Bridge runs automatically whenever your Trezor is connected.
Trezor Bridge follows the same open-source philosophy as other Trezor products. The source code is publicly available, allowing anyone to review it for transparency and security. It does not collect personal data, store private keys, or log sensitive activity. All cryptographic operations are performed inside the Trezor hardware wallet, ensuring complete isolation from your computer or browser.
Trezor Bridge® plays a vital role in the Trezor ecosystem by providing the secure communication pathway between your hardware wallet and your browser. Its lightweight design, cross-platform compatibility, and open-source transparency make it the most reliable solution for managing crypto assets online. By installing Trezor Bridge, you ensure smooth connectivity and maintain the uncompromising security that defines the Trezor experience.
