Bridge the gap between browser and device
In a world where software moves faster than hardware standards, Trezor™ Bridge acts as the resilient translator that keeps your workflow flowing. It handles device discovery, secure session establishment, and the controlled relay of encrypted messages so applications can request signing operations while your hardware device remains the final arbiter. The user experience is seamless; the security properties remain uncompromised.
Built for modern threat models
Bridge assumes hostile networks and cautious environments. It avoids remote intermediaries, runs exclusively on the local machine, and restricts functionality to the minimum necessary for safe communication. Public-key cryptographic measures protect message integrity, while the hardware device enforces consent by requiring physical verification before any private material is revealed or used.
Resilient developer surface
Integrations that rely on Bridge gain a predictable, versioned surface for device interactions. That predictability improves reliability across browser updates and operating system differences, resulting in fewer edge-case failures for end users. The bridge’s diagnostic outputs and clear status codes also help expedite troubleshooting when issues arise.
