SubQuery

“SubQuery’s mission is to make the world’s decentralised data more accessible. We are a data-as-a-service provider that aggregates and organises data from Polkadot and Substrate projects, serving up well-structured data for developers to use for a wide array of projects. Operating between layer-1 blockchains and decentralised apps (dApp), our service allows developers to focus on their core use case and frontend, without needing to waste time on building a custom backend for data processing.”
