Worked on the argotorg/sourcify repository to deliver HPP Network support, enabling contract verification on both HPP Mainnet and Sepolia Testnet. Focused on backend development and API integration, the work involved updating the chains configuration and implementing contract verification tests to ensure reliability across multiple networks. Leveraged TypeScript and JSON to streamline deployment workflows and reduce manual verification steps, while following test-driven development practices and integrating changes with continuous integration pipelines. This feature expanded multi-network compatibility, allowing customers to verify contracts on new networks and accelerating onboarding for multi-network deployments, with all changes traceable to a specific commit.
