Missing indexed Parameters in Events

Description

• The following events in the Game contract omit indexed parameters on critical values that would benefit from being indexed. Indexing allows for efficient off-chain filtering of logs via event topics, which is especially useful for dApps, monitoring tools, and analytics dashboards.

• The following parameters are not indexed but should be:

  • round in the GameEnded event

  • newRound in the GameReset event

  • newPlatformFeePercentage in the PlatformFeePercentageUpdated event

Risk

Likelihood:

• These events are emitted frequently (on game round ends, resets, or config updates), and external consumers (frontends, analytics platforms, etc.) will routinely query them.

• Without indexing, these platforms will need to scan full logs rather than use topics, which is computationally expensive and slow, especially as the contract gets older and logs accumulate.

Impact:

• Degraded frontend performance or responsiveness when querying historical data for rounds or configuration changes.

• Harder to implement scalable analytics or alerting systems.
