Trezor Bridge provides a trusted, lightweight connectivity layer between your Trezor hardware wallet and desktop or web interfaces. It keeps communication safe, reliable, and user-friendly so you can manage crypto with confidence.
Trezor Bridge is a small, secure application that runs on your machine and exposes a local, authenticated API for wallet interfaces to communicate with Trezor hardware devices. It solves browser compatibility issues, reduces attack surface, and centralizes connectivity logic so users benefit from a consistent, stable experience across platforms.
Unlike direct web-only access approaches, Bridge acts as an intermediary with strict origin checks and version negotiation. This design minimizes the risk of a malicious webpage interacting directly with your device and enables reliable behavior on Windows, macOS, and Linux.
When your Trezor is connected, Bridge exposes a local endpoint that authorized wallet apps can call. Every sensitive action (like signing a transaction) must be confirmed on the physical device — Bridge never signs or authorizes on its own. It simply provides a robust, authenticated transport.
Separates web content from the device interface to limit exposure to malicious pages.
Graceful reconnection logic when devices or cables temporarily disconnect.
Ensures compatibility and avoids downgraded clients or unexpected behavior.
Optional and minimal; no private key or transaction data is collected.
Installation is simple: download the official installer, run it, and follow the prompts. Typical steps:
If you see driver or permission prompts, follow the platform-specific instructions in the official documentation. Avoid third-party downloads — always use the official source.
Trezor Bridge is secure by design, but safe usage also depends on good habits:
Trezor Bridge is a connectivity tool facilitating secure communication between computers and Trezor hardware wallets. Cryptocurrency activities are inherently risky.
