Leaderboard + Rewards dApp is a minimal, production-ready example of an on-chain leaderboard and reward distribution system with a simple web frontend using ethers v6 and MetaMask connectivity.
User connects wallet, completes actions to earn points, watches rank update, and claims rewards after epoch settlement; admins configure rules, fund pools, publish top K, and settle tiers; judges see live demo of action → rank → claim loop with anti-gaming safeguards and transparent rules displayed in-app.
