Data Indexers

When building applications that leverage Flow data, developers have multiple Data Indexers to choose from. These platforms offer flexible options, allowing you to index all data on Flow, including information from both the Cadence VM and EVM. Alternatively, if your application doesn't require Cadence, you can opt to index only EVM data. This flexibility ensures that you can tailor your data indexing strategy to fit the specific needs of your application.

EVM & Cadence​

The Graph​

The Graph is an indexing protocol designed to organize and make blockchain data easily accessible through GraphQL. By leveraging The Graph, Flow applications can query open APIs, known as subgraphs, to efficiently retrieve data that has been indexed on the network. This allows developers to build serverless applications that operate entirely on public infrastructure.

Getting Started with The Graph

To begin using The Graph, refer to the official documentation. For a hands-on introduction, follow this quickstart guide to learn how to create, deploy, and query a subgraph.
