CertVault is a certification vault that uses to store, verify, and manage personal credentials. With on-chain proofs, QR verification, and expiry reminders, it puts control of your achievements.

Comment

Innovation

CertVault pioneers a decentralized approach to digital credentials by integrating Solana blockchain and QR-based verification. Unlike traditional systems, it ensures full user ownership, public verifiability, and seamless cross-platform access—enhanced by smart features like expiration alerts and wallet-based authentication.

Impact

CertVault addresses real problems like credential fraud, lost records, and slow verification processes. It serves students, professionals, HR teams, and institutions by making certification secure, transparent, and globally verifiable—promoting accessibility, integrity, and social good.

Execution

A working prototype is complete. Users can upload certificates, verify them with hash validation and QR codes, and get expiry alerts. Our live stack includes Solana, IPFS, React, and Phantom, all tested within the hackathon timeline.

Design & UX

We prioritized a simple, secure, and responsive UI. Certificates are auto-categorized, verifiable by QR, and managed easily via a wallet-authenticated dashboard—making onboarding smooth for both individuals and institutions.
