Introduction to Subgraph Development

To start coding right away, go to Developer Quick Start.

Overview

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.

What is GraphQL?

• 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.

Developer Actions

• 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.

What are Subgraphs?

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.
