Over five months, Butterbeer expanded decentralized exchange analytics in the duneanalytics/spellbook repository by integrating PancakeSwap data across multiple blockchains, including Arbitrum, BNB, opBNB, Solana, and Base. They engineered new data models and SQL pipelines to capture trades from evolving AMM protocols such as CLAMM and LBAMM, updating schemas and ETL processes to ensure comprehensive, cross-version trade analysis. Using SQL, dbt, and YAML, Butterbeer focused on data modeling, schema migrations, and on-chain data extraction, enabling richer analytics and improved data completeness. Their work demonstrated depth in blockchain data engineering, supporting more accurate DeFi insights without introducing major bugs.

Monthly work summary for 2025-08 focused on expanding DEX analytics coverage by adding PancakeSwap Infinity CLAMM and LBAMM support on Base in the spellbook repository. Implemented a data model for these trades and integrated it into the dex_base_base_trades aggregation to ensure trades from these versions are captured and analyzed, enabling more comprehensive analytics for Base-based trades.
