About Trézór Bridge
Trézór Bridge is the official local service that bridges the gap between your Trézór hardware wallet and desktop applications or supported web pages. It exists to solve a practical problem: modern browsers and apps often have divergent ways of handling USB devices, which creates friction for users trying to connect hardware wallets. Bridge provides a consistent and secure local endpoint. Its role is narrow but essential — enabling device discovery, permissions, and message transport while ensuring all cryptographic operations and approvals remain on your Trézór device.
The fundamental security model of Trézór devices depends on keeping private keys offline. Trézór Bridge does not change that model. Instead, it facilitates the safe movement of messages between an application and the device. When a transaction needs signing, the application sends a request to Bridge, Bridge forwards the request to the device, and the device presents the details on its screen. Only after you physically confirm the transaction does the device produce a signed response, which Bridge returns to the requesting application. This separation reduces attack surfaces and preserves the strong guarantees provided by hardware wallets.
Beyond security, Bridge enhances usability. Many users experience inconsistent device detection or confusing error messages when using browsers with evolving USB permissions. Installing Trézór Bridge often resolves these issues by offering a stable, local service that applications can rely on. This makes the overall experience smoother: devices are detected reliably, operations proceed without obscure permission problems, and developers can build integrations that work across platforms without resorting to unstable browser APIs.
Bridge is intentionally lightweight. It runs quietly in the background, starts with the system if you choose, and consumes minimal resources. Regular updates keep it compatible with the latest operating system changes and browser behavior. Cross-platform installers are provided for major desktop environments, and documentation is maintained to guide users through installation and troubleshooting steps. Keeping Bridge up to date is recommended to ensure the best compatibility and security.
From a privacy perspective, Trézór Bridge respects local-first principles. It does not broadcast device usage or personal data to external services. Connections are initiated by local applications and approved locally, and you can revoke access simply by closing the app or removing the device. These characteristics make Bridge a privacy-friendly complement to the hardware security model that defines Trézór’s approach.
Developers also benefit from the predictable environment Bridge provides. Applications can enumerate and communicate with devices through a stable endpoint, reducing the need for platform-specific logic. This reliability fosters stronger and more consistent integrations across wallets, exchanges, and tools, all while preserving the core security requirement that only the device signs operations after user confirmation.
In practical terms, installing Trézór Bridge is often the key step to a seamless desktop workflow. After installation, most users find their Trézór device behaves consistently across browser sessions and applications. If problems arise, official documentation offers clear troubleshooting steps: check cable connections, verify that Bridge is running, restart your browser, and review platform-specific instructions such as installing udev rules on Linux. These steps resolve the majority of common issues.
Ultimately, Trézór Bridge balances convenience and protection. It enables modern web and desktop integrations while ensuring that the strongest security guarantees remain in place: private keys that never leave the hardware and user-approved operations. If you use a Trézór device on a desktop, installing Bridge is a practical, secure choice that will make day-to-day management of your crypto simpler and more reliable.
