Entities
Overview
This sections briefs about all the available entities within Bunicorn Stable 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 Graph 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.

Historical Entities

These entities can be used to query things like total volume on a given day, price of a token on a given day, etc. For each DayData type, a new entity is created each day.
