First Flight #20: The Predicter

Summary

vent emission in smart contracts is crucial for tracking state changes and providing transparency. Events allow for easier debugging, monitoring, and verification of contract activities by off-chain applications. The contracts ThePredicter.sol and ScoreBoard.sol lack event emissions for critical state-changing functions, which undermines the ability to audit and track the system's behavior accurately.

Affected Functions

ThePredicter.sol

• register()

• cancelRegistration()

• approvePlayer()

• makePrediction()

• withdrawPredictionFees()

• withdraw()

ScoreBoard.sol

• setResult()

• confirmPredictionPayment()

• setPrediction()

• clearPredictionsCount()

Recommendations

The lack of event emission in key functions of ThePredicter.sol and ScoreBoard.sol contracts significantly impacts the ability to track and audit the contract's operations. By incorporating appropriate events, transparency and accountability can be greatly improved, ensuring all actions within the contracts are visible and verifiable.
