GitHub - pangolindex/subgraph: Subgraph schema for querying the Pangolin exchange contracts
GitHub
Pangolin's Subgraph Repository
This subgraph dynamically tracks any pair created by the Pangolin factory. It tracks the current state of Pangolin contracts and contains derived stats for things like historical data:
  • aggregated data across pairs and tokens,
  • data on individual pairs and tokens,
  • data on transactions
  • data on liquidity providers
  • historical data on Pangolin, pairs or tokens, aggregated by day

Key Entity Overviews

PangolinFactory
Contains data across all of Pangolin. This entity tracks important things like total liquidity, all time volume, transaction count, number of pairs, and more.
Token
Contains data on a specific token. This token-specific data is aggregated across all pairs and is updated whenever there is a transaction involving that token.
Pair
Contains data on a specific pair.
Transaction
Every transaction on Pangolin is stored. Each transaction contains an array of mints, burns, and swaps that occurred within it.
Mint, Burn, Swap
These contain specific information about a transaction. Things like which pair triggered the transaction, amounts, sender, recipient, and more. Each is linked to a parent Transaction entity.
