How we built it

The frontend of Verifium is crafted with the user-friendly React framework, seamlessly integrated with Web3js to ensure smooth interactions with the blockchain. For secure authorization, Verifium leverages the Phantom wallet, providing users with a robust and user-centric authentication experience. When it comes to transforming credentials into the NFT format, the process is facilitated through the Phantom wallet, adding an extra layer of security to the issuance of badges, certificates, and degrees. To streamline the listing and management of existing NFTs in users' wallets, Verifium taps into the power of SHYFT's API, offering a comprehensive solution for users to effortlessly navigate and showcase their academic achievements.

For dynamic and restriction-free meetings, Verifium integrates HURDLE's SDK and API. This allows users to participate in unlimited meetings, promoting collaboration without the constraints of traditional platforms. Behind the scenes, Verifium ensures data integrity by partially storing information in MongoDB, including public wallet addresses and related data. Simultaneously, for enhanced security and decentralization, a portion of the data is stored on the IPFS network, contributing to a reliable and resilient system. In essence, Verifium orchestrates a harmonious blend of cutting-edge technologies, seamlessly combining React, Web3js, Phantom wallet, SHYFT's API, HURDLE's SDK, and MongoDB/IPFS to create a user-centric and secure platform for credential management and collaborative meetings.
