As a developer, you need data to build and power your dapp. Querying and indexing blockchain data is challenging, but The Graph provides a solution to this issue.

On The Graph, you can:

1. Create, deploy, and publish subgraphs to The Graph using Graph CLI and Subgraph Studio.
2. Use GraphQL to query existing subgraphs.

• GraphQL is the query language for APIs and a runtime for executing those queries with your existing data. The Graph uses GraphQL to query subgraphs.

• Query subgraphs built by other developers in The Graph Network and integrate them into your own dapps.
• Create custom subgraphs to fulfill specific data needs, allowing improved scalability and flexibility for other developers.
• Deploy, publish and signal your subgraphs within The Graph Network.

A subgraph is a custom API built on blockchain data. It extracts data from a blockchain, processes it, and stores it so that it can be easily queried via GraphQL.

Check out the documentation on subgraphs to learn specifics.
