Subgraph
Subgraph schema for querying the Pangolin exchange contracts

Pangolin Subgraph

An open source subgraph index for Pangolin -- a community-driven decentralized exchange for Avalanche and Ethereum assets with fast settlement, low transaction fees, and a democratic distribution -- powered by Avalanche.
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

Mint, Burn, Swap
These contain specifc information about a transaction. Things like which pair triggered the transaction, amounts, sender, recipient, and more. Each is linked to a parent Transaction entity.
