SubQuery

SubQuery is a blockchain developer toolkit and the backbone of web3 infrastructure. A SubQuery project is a complete API to organise and query data from chains. Operating between layer-1 blockchains and decentralised apps (dApp), SubQuery is an open-source indexer organising and serving well-structured data over GraphQL. 

SubQuery’s protocol abstracts away blockchain data idiosyncrasies with the SubQuery SDK, allowing developers to focus on deploying their core product without needlessly wasting efforts on custom backend technologies.

SQT is a utility token that powers the SubQuery Network with three main use cases:

• To create a reward incentive mechanism for Delegators and Indexers (node operators);
• To act as a medium of exchange on the network marketplace;
• To enable governance of the protocol.
