What is Graph?
The Graph (GRT) is an indexing protocol that plays a role in requesting data for networks such as Ethereum and IPFS. Not only that, this protocol also plays a role in supporting most DeFi applications and the broader Web3 ecosystem.
Anyone can create and publish an open API known as a subgraph. Subgraphs can be queried by applications that use GraphQL to extract data from the blockchain. The Graph currently supports indexing data from Ethereum, IPFS and POA.
