About Trezor Bridge

The Trezor Bridge component bridges the gap between your desktop (or laptop) and your Trezor hardware wallet. It abstracts USB negotiation, manages permissions, and presents a consistent API to wallet applications. Because the security model relies on holding private keys inside the hardware device itself, Trezor Bridge focuses on reliability and minimal attack surface. Integrations with web wallets use the Bridge to request transaction signatures while prompting users to confirm actions physically on their device display. The result is a highly secure, transparent workflow that balances usability and defense-in-depth security.

Why it matters

With increased interest in self-custody, people need a trustworthy connectivity layer. Trezor Bridge reduces technical friction while keeping interactions auditable. For developers, it simplifies testing and deployment. For end users, it reduces confusion with consistent messaging across browsers and operating systems. For organizations, it provides a predictable, maintainable component that supports hardware wallet stewardship at scale.

Frequently Asked Questions

1. What is Trezor Bridge and why do I need it?

Answer: Trezor Bridge is a small helper app that allows your browser or desktop wallet to communicate with a Trezor device via USB. It is required for many desktop setups to ensure secure, stable connections.

2. Is Trezor Bridge safe to install?

Answer: Yes. The Bridge only handles connection logic. Private keys remain on the Trezor hardware; signing and confirmation always occur on-device.

3. Which operating systems support Trezor Bridge?

Answer: Windows, macOS, and most modern Linux distributions are supported. Always download the official Bridge from the Trezor website to avoid impersonators.

4. What if my browser doesn’t detect my Trezor?

Answer: Try restarting the Bridge service, reconnecting the cable, or using a different USB port. If problems persist, reinstall the latest Bridge version and consult the Trezor troubleshooting guides.

5. Can Trezor Bridge be used in headless or CI environments?

Answer: Bridge is primarily designed for interactive desktop use. For automated workflows, look into dedicated developer tools and APIs that are designed for non-interactive signing with secure controls.
