A Web3-based MCQ exam system on Polygon rewards users with NFTs based on scores. It integrates Web3.js, MetaMask, and OpenSea, using ERC-721 smart contracts for seamless blockchain interactions.
In the evolving landscape of online education, our project introduces a Web3-powered MCQ-based exam system that rewards participants with NFTs based on their performance. By leveraging Polygon blockchain and ERC-721 smart contracts, we ensure a decentralized and transparent reward mechanism.
Participants register using their wallet addresses, take the exam, and receive random NFT rewards according to their scores. The integration of Web3.js and MetaMask facilitates seamless blockchain interactions, while OpenSea provides a marketplace for NFT visibility. This system not only enhances engagement but also brings a new dimension of gamification and digital ownership to online assessments.
