During March 2026, Hyd628 contributed to the MystenLabs/sui repository by developing a cross-network gRPC verification sample for the Address Balances Migration Guide. Hyd628 implemented a TypeScript-based test script that validates the enable_address_balance_gas_payments protocol flag across mainnet, testnet, and devnet, leveraging gRPC and API integration skills. The solution included automated verification steps using getEpoch with readMask, providing clear results for each network and reducing manual validation effort. Hyd628 also added release notes scaffolding and documentation guidance, enhancing developer onboarding. This work demonstrated depth in TypeScript and gRPC, focusing on maintainability and clarity for future users and contributors.
