Developed and delivered XDC Network Mainnet support for the argotorg/sourcify repository, expanding the platform’s multi-chain compatibility and enterprise readiness. The work involved implementing backend configuration for the XDC Network (chain ID 50) and updating the TypeScript-based test suite to ensure accurate recognition and end-to-end verification of the new chain and its associated smart contract. By enhancing network onboarding and improving chain detection reliability, the changes enabled broader market adoption and more robust multi-chain discovery. The focus on backend development, smart contract integration, and comprehensive testing contributed to improved test coverage and system reliability without introducing new bugs.
