Using The Graph on Boba

Using The Graph on Boba

The Graph is an indexing protocol for organizing blockchain data and making it easily accessible (with a service called GraphQL). You can define contract of interest, set up The Graph to ingest events/data that you define, and you can then obtain these data through GraphQL.
