Features & Benefits

Trezor Bridge is the secure, lightweight companion that connects your hardware wallet to modern web browsers and Web3 applications. Built with an emphasis on privacy and reliability, Bridge acts as a minimal, trusted intermediary that lets your Trezor device communicate with decentralized exchanges, token platforms, and wallet interfaces without exposing secret keys. It supports multiple operating systems and browsers, and when paired with a Trezor hardware device it streamlines firmware updates, device initialization, and trusted origin management. Beyond basic connectivity, Trezor Bridge offers consistent device detection and session management, automatically re-establishing trusted connections and avoiding common USB/permission obstacles. For developers, Bridge exposes a stable API surface that plays well with popular libraries while minimizing attack surface through scoped permissions and message validation. For end users, the experience is simple: connect, approve, and sign — with clear prompts on the device itself that make malicious remote signing attempts visible and rejectable. Security is the core value of Bridge. It complements Trezor’s isolated key storage and open-source firmware by adding a hardened transport layer designed to limit exposure. Transport-level features include trusted origin checks, certificate pinning strategies where applicable, and minimal privileged footprint on the host system. Combined with best-practice operational hygiene — such as verifying addresses on the hardware screen and keeping firmware up to date — Bridge helps maintain a robust defense-in-depth posture for everyday Web3 use. Usability remains a priority: Bridge reduces friction for multi-account management, supports a wide range of cryptocurrencies, and provides logging and diagnostics for troubleshooting without revealing sensitive secrets. It is regularly updated to support new browsers and OS changes, which reduces the risk of sudden breakage when web standards evolve. In short, Trezor Bridge is an essential piece in a secure Web3 workflow — small, focused, and designed so the user stays in control of their keys while enjoying seamless connectivity and compatibility. Regular security audits and a clear changelog make it easy to verify improvements, and community-driven support channels provide guidance that helps users resolve issues quickly and confidently.

Developer Notes

Bridge exposes a compact JSON-RPC style API, with clear message schemas and permission prompts. Its design favors minimal host privileges, reproducible behavior across platforms, and compatibility shims so dApps can rely on stable device presence. Integrators should follow the recommended origin-checking flows and verify device prompts programmatically where possible.

Support & Resources

For troubleshooting, consult official documentation and changelogs, use diagnostic logging when instructed, and verify firmware versions via the hardware screen. Community forums and developer channels provide compatibility guides and example integrations.
