Entities
Overview
This section briefs about all the available entities within Bunicorn Flexible Subgraph. Entities define the schema of the subgraph, and represent the data that can be queried. Each entity has a set of fields that store relevant information about the entity. To see an interactive sandbox of all entities see the Subgraph Explorer.
Each entity is defined with a value type, which will always be a base AssemblyScript type, or a custom type provided by The Graph's custom TypeScript library. For more information on value types see here.
