Contributed targeted sanity tests to the ethereum/consensus-specs repository, focusing on the Gloas protocol’s withdrawal recovery mechanisms. Developed Python-based test automation to validate scenarios where withdrawal-eligible validators are present but payloads fail to arrive, ensuring the protocol can recover across multiple blocks. This work enhanced the test suite’s coverage of edge cases, reducing operational risk for validators and reinforcing the reliability of on-chain withdrawal recovery paths. By structuring tests for reproducibility and governance readiness, the developer applied blockchain development and testing expertise to strengthen protocol resilience and support robust validator operations within the Ethereum consensus specification framework.
