About SubQuery

SubQuery’s mission is to make the world’s decentralised data more accessible.

SubQuery is a blockchain developer toolkit enabling others to build Web3 applications of the future. A SubQuery project is a complete API to organise and query data from layer-1 chains. Currently servicing Polkadot, Substrate and Avalanche projects, this data-as-a-service allows developers to focus on their core use case and front-end, without needing to waste time on building a custom backend for data processing.

The SubQuery Network proposes to enable this same scalable and reliable solution, but in a completely decentralised way.
