The IntelliCasino Betting Smart Contract provides a decentralized platform for spectators to place bets on a quiz player's performance in real-time games. The contract is built on the Ethereum blockchain and manages two types of bets: bets on the quiz player winning (by achieving 75%+ accuracy) and bets on IntelliCasino winning (if the player scores below 75%). It leverages Solidity, follows security best practices, and ensures proper fund distribution between the winning side and the casino's commission.
- Decentralized Betting: Allows spectators to place bets on a quiz game outcome (player vs. IntelliCasino).
- Transparent Fund Management: Tracks bets on both sides (player and casino) and securely stores funds during gameplay.
- Secure Fund Distribution: Distributes winnings fairly to bet winners based on a dynamic payout ratio.
- Commission Collection: Automatically deducts a 3% commission from the total bet pool before distributing winnings.
- Security Best Practices: Reentrancy attack protection and secure transfer mechanisms ensure the contract’s robustness.
- A new game can be created by the casino owner (which is the frontend application).
- Each game has an ID provided by the frontend and can only accept bets during its OPEN state.
- Spectators can place bets on the player or casino using the
placeBet()function. - The contract ensures that spectators can only place bets when the game is in an OPEN state.
- Spectators can add to their existing bets until the game is closed.
- Before the game is closed, spectators can withdraw their placed bets using
withdrawBet(). - The contract handles bet removal from the active pool and ensures the user's funds are transferred back securely.
- Once the game begins, the owner can close the game using the
closeGame()function, preventing further bets or withdrawals.
- After the game concludes, the contract calculates the payout ratio and distributes the winnings to the winners (based on whether the player won or the casino won).
- The casino takes a 3% commission from the total bet pool before winnings are distributed.
- The contract ensures enough funds are available before any transfer.
- Reentrancy Guards: Each bet and withdrawal updates the contract’s state before any transfer, preventing reentrancy attacks.
- Modifiers for Ownership: Only the contract owner can create games, close games, or distribute winnings, ensuring that the contract is operated by authorized entities.
- Gas Optimization: Careful use of
memoryandstoragefor minimizing unnecessary gas consumption.
