The Graph (GRT) is an indexing protocol, with the mission to be the APIs for a decentralised future. The Graph allows anyone to build and publish open APIs, called subgraphs, to make data easily accessible. The Graph fits nicely with the new era of Web3, where all data is stored and processed on open networks with verifiable integrity. The Graph makes querying this data fast, reliable and secure. The Graph currently supports a number of networks, including Ethereum, Polygon, Binance Smart Chain and Avalanche. There are four roles that participants can play in the GRT ecosystem: Developer, Indexer, Curator and Delegator.
