Executive Summary
Trézór Bridge is the new companion application designed to securely connect hardware wallets and secure elements to modern desktop and web applications. This release reimagines the bridge pattern: a lightweight background service plus a modern user interface that guides device setup, permissions, and signing flows. The app focuses on three core principles—security, usability, and interoperability—enabling both power users and newcomers to manage keys and sign transactions with confidence.
Why Trézór Bridge
The crypto ecosystem contains many fragmentation points: varied browser policies, differing USB and WebHID behavior, and inconsistent UX across wallets. Trézór Bridge addresses these by providing a single trusted interface and a documented API for third-party integrators. Developers can integrate quickly while relying on robust device discovery, clear user prompts, and auditable logs.
Key Features (H3)
- Secure Device Discovery: Strong device attestation and human-readable prompts prevent accidental approvals.
- Cross-Platform: Windows, macOS, and Linux packages with a headless daemon and optional GUI.
- Modern UX: Guided first-run flow, step-by-step device setup, and inline help for common tasks.
- Developer-Friendly API: Well-documented JSON-RPC endpoints with CORS-safe connectors for web dApps.
- Privacy-Minded: Minimal telemetry, local-only key metadata, and explicit consent controls.
Architecture (H4)
Architecturally, Trézór Bridge separates concerns: a privileged background service handles low-level I/O with hardware devices and exposes a secure local socket; the renderer/UI is sandboxed and communicates only over defined channels. This reduces attack surface and ensures that cryptographic operations occur only after explicit, verifiable user approvals.
Security Model (H4)
The security model enforces user consent for every signing operation, displays a transaction summary on-device for verification, and supports device firmware attestation where available. The bridge verifies that the host is trusted and stores only ephemeral session keys—no private keys or seeds are persisted by the application.
Getting Started (H3)
To start using Trézór Bridge: download the installer for your OS from the official download, run the app, and follow the onboarding wizard. Developers can view integration examples and the API specification at the documentation center.
Target Audiences (H3)
Trézór Bridge is built for three groups: individual users wanting a dependable way to connect hardware wallets; dApp developers needing predictable device connectivity; and enterprise integrators who require auditable signing and deployment options.
Product Roadmap
The near-term roadmap prioritizes improved browser integration, multi-device sessions, and an SDK for mobile apps. Mid-term goals include automated firmware verification and a plugin system for third-party tooling. Community feedback will shape prioritization—visit the roadmap to participate.
Commercial & Open Source Options
The core bridge is offered under a permissive open-source license; commercial support and extended features (enterprise deployment, advanced audit logs, priority support) are available for organizations that require SLA-backed services.
Conclusion
Trézór Bridge brings modern bridging patterns to hardware security devices, combining careful security engineering with a polished user experience. It reduces integration friction for developers and raises the bar for secure, auditable interactions between wallets and the apps that rely on them. We invite users and developers to try the release, review the documentation, and join the community discussion.
