Project Description

CryptoCasino is a Farcaster Mini App built on the Monad Testnet where users predict memecoin prices in real-time. Players join short rounds by delegating bets via MetaMask Smart Accounts, and the winner — whose guess is closest to the actual price — takes the pot. Prices are fetched securely using Chainlink Oracles, ensuring transparency and fairness.

How it's Made

šŸŽ® Admin-controlled Game Creation — Only the admin can create new games with a selected memecoin symbol. ā±ļø Timed Rounds — Each game lasts 20 minutes; players can join in the first 10 minutes. šŸ’° Delegated Bets — Players delegate a fixed bet amount to the contract using MetaMask Delegation Framework. šŸ”— Oracle Integration — Fetches memecoin prices via Chainlink for tamper-proof results. šŸ† Automatic Winner Resolution — The player closest to the final oracle price wins the pooled amount. šŸ“Š Leaderboard System — Tracks total wins and total earnings for every player. 🌐 Farcaster Integration — Built as a Farcaster Mini App so users can play directly inside Farcaster Frames.
