The Graph is a decentralized indexing and querying protocol for onchain data. It is the original decentralized data marketplace that introduced subgraphs, the most flexible way of indexing onchain data that builders can fully customize according to their needs. Subgraphs have become web3’s standard method of indexing and accessing onchain data. Since its launch in 2018, thousands of builders have developed tens of thousands subgraphs across 40+ blockchains - including Ethereum, Base, Arbitrum, Optimism, Polygon, Celo, Fantom, Gnosis Chain, Avalanche, and more.
