Token Holders Subgraph

Intended Uses

• Tracking the number of holders of a particular token
• Tracking the balances of particular token and holder combinations

Architecture

Considerations

• Calculating daily balances within a subgraph is currently prohibitively slow, so this is outsourced to the Google Cloud Function deployed by the token-holder-balances repo.

Design Principles

• The subgraph should need minimal maintenance
• The subgraph entities should enable users to calculate the metrics they need (i.e. don't try too hard to anticipate the metrics needed)

Indexing

Indexing takes place in the following circumstances:

• Transfer function call
  • When the transfer function is called on any of the tokens, a TokenHolderTransaction record is created for each of the sender and receiver.
