What are Curators on The Graph?
Curators are essential participants in The Graph protocol whose primary role is to signal which data sources (called “subgraphs”) should be indexed by the network. Their main tasks, incentives, and responsibilities include:
1. Role & Purpose
- Curators use their expertise to evaluate subgraphs—standardized APIs mapping blockchain data—and signal which are high-quality and most useful to decentralized applications (dApps).
- By “signaling,” Curators stake GRT tokens on a specific subgraph, which creates a “signal” via a bonding curve mechanism123.
2. Incentives & Economics
- Curators earn a share of the query fees generated by the subgraphs they signal on. The more useful and highly used a subgraph, the more query fees it produces, providing incentives for Curators to identify and support subgraphs with the greatest utility and accuracy.
- Their signal directly influences Indexers—another key participant in The Graph—by helping them decide which subgraphs to prioritize for indexing and serving queries.
- Staking on a low-quality or unused subgraph entails risk; Curators could lose part of their staked GRT due to protocol mechanics like the curation tax (a portion of staked GRT is burned to prevent spam and abuse)4.
3. Who Can Be a Curator?
- Almost anyone can become a Curator—developers, data professionals, or non-technical community members. All that’s required is a web3 wallet and some understanding of dApps and blockchain data. Technical expertise is helpful but not mandatory43.
- Curators can be subgraph developers themselves, users familiar with decentralized ecosystems, or analytics/data professionals interested in Web3 infrastructure24.
4. How Curation Works
- Curators review available subgraphs, assess their quality and reliability, and then stake (signal) GRT as a vote of confidence.
- Indexers monitor the amount of GRT signaled to help decide which subgraphs are worth indexing, creating a decentralized, market-driven quality filter for blockchain data APIs.
- As subgraphs generate query fees, Curators receive a portion, incentivizing ongoing attention to data quality143.
5. Protocol Benefits and Community
- The curation system aims to ensure The Graph indexes only the most valuable and trusted data sources—a critical feature as data in the Web3 space is open, permissionless, and continuously expanding.
- A vibrant community of Curators has formed around these incentives, including educational efforts, forums, and support mechanisms for both newcomers and advanced participants25.
