Worked on the PonziLand repository to address a simulation accuracy issue in smart contract logic, focusing on the nextclaiminfo function. Refactored the per-neighbor time_to_nuke calculation by moving it inside the neighbor loop, ensuring that each neighbor’s location was processed independently and preventing incorrect cross-neighbor application. This targeted bug fix improved the reliability of claim processing and enhanced the stability of neighbor-based interactions within the simulation. The update was delivered as a localized, easily reviewable patch, demonstrating careful debugging and clear commit practices. Utilized the Cairo programming language and applied smart contract development skills throughout the process.
