Trezor Bridge is the secure communication software that connects your Trezor hardware wallet to your computer and browser. It ensures that data flow between the Trezor device and Trezor Suite remains encrypted and authentic, providing seamless crypto management without exposing sensitive information.
Think of it as the invisible digital bridge that connects your offline wallet to the online world — safely, efficiently, and transparently.
Trezor Bridge acts as an intermediary layer between your hardware wallet and the host environment (browser or desktop app). It replaces outdated browser plugins and provides stable, secure connections via encrypted protocols. This design ensures that your private keys never leave the device.
Visit https://trezor.io/start to download the latest version of Trezor Bridge. Choose the correct installer for your operating system (Windows, macOS, or Linux). Once installed, it runs silently in the background, enabling the Trezor Suite to recognize your connected device instantly.
When you connect your Trezor device, the Bridge establishes a secure local connection using HTTPS over localhost. It manages device requests, signature verifications, and message exchanges. The Bridge doesn’t store data — it merely relays signed information securely.
All sensitive cryptographic operations happen within the Trezor hardware itself, isolating your private keys from any exposure.
If issues persist, reinstall the Bridge and reconnect your device. The Trezor support site also provides command-line troubleshooting tools for advanced users.
Trezor Bridge upholds core security principles:
Developers can run Trezor Bridge manually or integrate it with test environments using local web servers. The Bridge exposes a simple API for applications to communicate with Trezor hardware via secure calls.
This makes it ideal for custom crypto tools, exchanges, or private wallet systems that want direct device communication without compromising security.
Trezor Bridge is designed for lightweight operation, consuming minimal system resources. It auto-updates silently and reconnects automatically after system sleep or device replugging. Network latency is negligible because all operations occur locally.
Trezor Bridge ensures seamless and secure interaction between your hardware wallet and Trezor Suite. By following installation best practices, keeping software updated, and maintaining good device hygiene, you can ensure your digital assets stay safe from threats while remaining easily accessible.
