Developed and integrated Mezo blockchain network support into the argotorg/sourcify repository, focusing on automatic endpoint discovery to streamline onboarding of new networks. The implementation removed the need for explicit RPC configuration by updating default chain settings, thereby reducing manual setup and operational overhead. Validation was achieved through a dedicated verification test and deployment of a test contract, ensuring robust end-to-end integration. The work leveraged TypeScript and JSON for configuration and testing, applying skills in blockchain integration and full stack development. This feature enables seamless addition of new networks, improving maintainability and efficiency for future blockchain onboarding within the project.
