Developed and delivered Monad blockchain integration for the 0x API within the duneanalytics/spellbook repository, enabling multichain support and introducing new trade and settler models to enhance cross-chain analytics. The work involved updating SQL-based data models, aligning monad-specific structures with broader multichain tables, and making essential configuration and seed-data adjustments, such as mapping WMATIC to WPOL for Polygon compatibility. Leveraging skills in SQL, data modeling, and blockchain integration, the developer focused on scalable architecture to support expanded DeFi workflows. Collaboration was demonstrated through co-authored commits, ensuring the platform is positioned for future growth in decentralized analytics capabilities.
