description The Graph Overview

The Graph facilitates efficient querying of blockchain data. It’s a decentralized indexing protocol allowing developers to access information on networks such as Ethereum via GraphQL. This enables the creation of Web3 applications by providing a standardized way to retrieve and utilize data from smart contracts. Primarily used by developers building decentralized applications and those requiring reliable, off-chain data for analysis or integration.

help The Graph FAQ

What blockchain networks does The Graph support for indexing besides Ethereum?

The Graph supports indexing across multiple networks including Polygon, Arbitrum, Optimism, Avalanche, Celo, Fantom, and IPFS, among others. Developers can deploy subgraphs that query data from any supported chain through a unified GraphQL API.

What is the GRT token used for in The Graph protocol?

GRT is an ERC-20 token on Ethereum used for staking by indexers, curators, and delegators who provide data indexing and query processing services. Indexers stake GRT to participate in the network and can be slashed for serving incorrect data, while delegators stake GRT behind trusted indexers to earn a share of query fees.

When did The Graph launch its decentralized mainnet?

The Graph's decentralized mainnet launched in December 2020, transitioning the protocol from a centralized hosted service to a distributed network of independent indexers. Prior to mainnet, many early DeFi applications like Uniswap and Aave relied on The Graph's hosted service for querying on-chain data.

What is a subgraph in The Graph ecosystem?

A subgraph is an open-source API specification that defines how data from specific smart contracts should be indexed and queried. Applications like decentralized exchanges and NFT marketplaces rely on published subgraphs to retrieve historical data and real-time state changes using standard GraphQL queries.
