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
