HealthVaultChain

Inspiration

We were inspired by the painful reality that millions of lives are affected each year due to the lack of accessible and unified medical records. From emergencies where doctors have no prior information, to patients repeating tests because hospitals don’t share data, we knew there had to be a better way. We wanted to build something that could truly save lives with technology, and blockchain provided us with the foundation to do so securely.

What it does

HealthVaultChain is a blockchain-based web application that allows hospitals and users to store, access, and share medical records securely. It has:

A unified search bar that lets hospitals retrieve a patient’s complete medical history using their unique ID. Biometric access control, where patients can unlock their records with a fingerprint or phone. A dashboard for both patients and hospitals to manage data, requests, and access. Encrypted record sharing across verified institutions, all backed by blockchain for trust and immutability.

How we built it

Bolt.New: For rapid UI/UX development Radix UI and Tailwind CSS for clean, responsive components Blockchain smart contracts for managing access logs and recording ownership Fingerprint logic (simulated with a secure approval step) for biometric authentication A modular component structure with shared elements between patient and hospital dashboards

Challenges we ran into

Implementing blockchain logic within a web environment like Bolt.New required simulating parts of the backend. Creating a real-time search experience that works with decentralized data was tricky without a central database. Balancing security with accessibility, ensuring hospitals don’t overreach while still getting fast access in emergencies. Designing a unified UX for two very different users: patients and hospitals.

What we learned

We learned how powerful and flexible blockchain can be when solving real-world healthcare problems. We saw the importance of user experience in designing tools for both tech-savvy hospitals and everyday patients. We gained experience integrating frontend design with secure backend principles in a no-code/low-code platform.

What's next for HealthVaultChain

Implementing real fingerprint authentication using biometric APIs.

Launching a pilot with local hospitals to test adoption and workflow integration.

Adding AI summarization of medical records for faster doctor review.

Expanding to include pharmacies and insurance providers for a fully connected health ecosystem.

Open-sourcing part of the project to invite more developers into the mission.
