SubQuery Network
SubQuery’s mission is to help others create products that allow us to move to a decentralized future faster. SubQuery is a blockchain developer toolkit and the backbone of web3 infrastructure. A SubQuery project is a complete API to organize and query data from chains. Operating between layer-1 blockchains and decentralized apps (dApp), SubQuery is an open-source indexer organizing and
serving well-structured data over GraphQL. SubQuery powers the next generation of dApps and tools with web3 data.
Currently, anyone can already use SubQuery to extract and query blockchain data in only minutes and at no cost but in a centralized way. The SubQuery Network proposes to enable this same scalable and performant solution, but in a completely decentralized way.
