QuizETH

QuizETH is a gamified, on-chain learning platform designed to educate users about Web3 and blockchain concepts in an engaging, rewarding way. Built for the EduChain Hackathon 2025, QuizETH combines educational quizzes, real token incentives, and an AI assistant to make blockchain education fun and interactive.

Users can connect their wallets, take static Web3 quizzes, and submit their scores to earn QET tokens—a custom ERC20 reward token. Top performers are ranked in a live on-chain leaderboard, and all users can claim their accumulated rewards directly from the contract.

To further support learning, QuizETH integrates an AI-powered chatbot assistant, which helps explain concepts, clarify quiz content, and guide users toward deeper understanding of Web3.
