Convex Subgraphs are a suite of GraphQL interfaces hosted on the Graph network that provide unified APIs for querying on-chain data from the Convex Finance Protocol.  These subgraphs enable developers to index and access a wide range of historical on-chain events across multiple areas of the platform. Convex maintains several subgraphs, each responsible for indexing various aspects of the protocol. With Convex subgraphs, developers can easily retrieve relevant data without the need to manually interact with multiple contracts on the Ethereum blockchain.
