What is SubQuery?

SubQuery is an open-source and universal blockchain data indexer for developers that provides fast, flexible, reliable, and decentralized APIs to power leading multi-chain apps. It is a blockchain developer toolkit facilitating the construction of Web3 applications of the future. A SubQuery project is a complete API to organize and query data from layer 1 chains. Currently servicing Ethereum, Polygon, BNB, NEAR, Polkadot, Avalanche, Algorand, Cosmos, Arbitrum, and Flare projects, this data-as-a-service platform allows developers to focus on their core use case and front-end without wasting time building a custom backend for data processing activities. In the future, the SubQuery Network intends to replicate this scalable and reliable solution in a completely decentralized manner.
