Trezor™ Bridge is a simple, intentional service that runs on your local machine and mediates communications between applications and your Trezor hardware wallet. It's designed to be unobtrusive: once installed, Bridge waits for your device, provides clear status, and forwards encrypted messages so that signing operations happen only after you confirm them on the device itself. This approach preserves the security boundaries you expect from a hardware wallet while delivering a smooth user experience.
The bridge gives clear, human-focused diagnostics when connectivity issues occur, including friendly guidance for common cases like USB permissions and device availability. It uses a minimal permission model and operates without sending any sensitive content to external services. The result is a predictable, supportable experience for individuals and teams who need dependable hardware interactions.
No cloud routing; messages stay on your machine while the device enforces signing controls.
Lightweight service with small resource usage and straightforward installation.
Readable status messages and simple guidance for resolving common connectivity problems.
If you pair a hardware wallet with desktop software or use browser-based wallet interfaces that require USB access, Bridge simplifies and stabilizes that connection. It’s also useful for developers building integrations that need a documented local interface to interact with devices reliably.
