# DeFi Canonical Data Our DeFi Canonical Data covers historical data for variety of different protocols types. Within each protocol type, there is a shared schema that covers core pool-level metrics and events specific to that type. This allows for metrics within protocol types to be easily compared/queried together. Protocol and vertical level metrics can be created from the aggregation of this data and can also be access in DeFi Protocol Metrics Protocol Types Supported: * Automated Liquidity Manager * Bridge * Derivative * DEX Aggregator * DEX * Lending * Liquid Staking * NFT Marketplace * Prediction Markets * Yield Aggregators --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
