Database

This skill covers the extraction, transformation, and loading (ETL) of blockchain data into structured databases or data warehouses. You use this when building scalable analytics platforms, dApps requiring extensive historical data, or custom indexing services that go beyond simple RPC queries, enabling complex analysis and reporting.

This skill enables you to leverage DefiLlama's comprehensive aggregated data for decentralized finance protocols. You utilize this when building applications that require insights into Total Value Locked (TVL), historical protocol performance, yield opportunities, and cross-chain liquidity metrics, providing a standardized view of the DeFi landscape.

This skill enables you to leverage Dune Analytics for querying, analyzing, and visualizing blockchain data using SQL. You use this when building dashboards, creating custom data insights, or integrating on-chain data into applications, transforming raw ledger information into actionable intelligence.

This skill enables you to query, analyze, and visualize vast amounts of blockchain data using SQL. You leverage Flipside Crypto when you need deep, structured insights into on-chain activity, smart contract interactions, or token movements across multiple networks, without the complexity of direct RPC node parsing.

This skill teaches you to analyze, predict, and optimize transaction fees (gas) on EVM-compatible blockchains. You leverage gas analytics to minimize operational costs, improve user experience by ensuring timely transaction finality, and make informed decisions about dApp deployment and interaction strategies, especially during network congestion.

This skill empowers you to leverage Nansen Analytics' proprietary on-chain data and entity labeling for enhanced insights into blockchain activity. You employ Nansen when your applications demand deep, real-time intelligence on market movements, smart money flows, and whale activity, going beyond raw RPC data.

This skill equips you to extract, interpret, and analyze data directly from blockchain ledgers. You use this when building applications that require real-time insights into smart contract state, transaction history, or token movements, providing verifiable and immutable data sources.

This skill enables you to analyze on-chain wallet activity to build comprehensive user profiles. You leverage this when segmenting users, assessing risk, detecting fraud, or personalizing dApp experiences based on a wallet's transaction history, token holdings, and contract interactions.
