Lucky Me

Overview

Lucky Me is a blockchain-based prediction game where players stake CORE, submit answers to randomly generated questions, and earn points for correct predictions. Players are ranked on a leaderboard based on their total points. The game is powered by a React + TypeScript frontend integrated with a Solidity smart contract deployed on the blockchain.

Tech Stack

Frontend

• React.js – User interface
• TypeScript – Type safety and development efficiency
• RainbowKit – Wallet connection and Web3 interactions
• Ethers.js – Smart contract interaction
• Tailwind CSS – Styling

Smart Contract

• Solidity – Smart contract logic
• Hardhat – Smart contract development and testing
• Core DAO Blockchain – Deployed network
• Chainlink VRF (Verifiable Random Function) – Ensures fair randomness in AI-generated predictions

Features

• Wallet Connection: Users connect via RainbowKit.
• CORE Staking: Players stake CORE before playing.
• AI-Powered Answer Generation: The game utilizes an AI agent to generate random answers for each prediction question.
• Blockchain-Based Randomness: AI-generated answers are verified using on-chain randomness, ensuring fairness and unpredictability.
• Prediction System: Players submit answers to game questions.
• Automated Scoring: Points awarded based on correct answers.
• Streak Bonus: Extra points for consecutive correct answers.
• Leaderboard: Top players ranked by total points.
• Smart Contract Integration: Data stored securely on-chain.

How It Works

1. Stake CORE Tokens: Players must stake 0.02 CORE before starting a game.
2. Receive 10 Questions: The game presents 10 randomly generated prediction-based questions.
3. AI Randomly Selects Answers: A blockchain-based AI agent determines correct answers using Chainlink VRF for fairness.
4. Answer Submission: Players select either option A or B as their prediction.
5. Scoring System:
   • Correct answer: +100,000 points
   • Incorrect answer: -20,000 points
   • 3 consecutive correct answers: +50,000 bonus points
6. Leaderboard & Rewards: Players are ranked by their scores. If a player gets 8 or more correct answers, they double their stake.
