What is SushiSwap Subgraph?
SushiSwap protocol maintains a series of subgraphs powered by the Graph Protocol. These subgraphs work by extracting information from various events emitted by the protocol's smart contracts, which are deployed on various chains. Developers can easily access and analyze on-chain data such as account balances, token and pool information, transaction history, and much more. The data is indexed and cached, which can be queried later using an exposed GraphQL API.
