@Hussman256 has applied to work on this issue as part of the Stellar Wave Program's 2nd wave.

I would like to work on this issue because gamification mechanics streak multipliers, point thresholds, bonus tiers require precise on-chain math and careful state management to prevent exploits like reward manipulation or multiplier stacking bugs. This is exactly the kind of contract logic I enjoy working through.

I have experience building reward distribution systems and understand the importance of making multiplier calculations deterministic and overflow-safe. I'll ensure the contract handles edge cases cleanly such as expired streaks, cap limits, and concurrent reward claims and deliver well-documented, testable code within the Wave.
