The Uniswap V2 Subgraph is an advanced, open-source data indexing tool designed to dynamically monitor and analyze the state of Uniswap’s decentralized exchange protocol on Ethereum. This subgraph efficiently tracks all pairs created via the Uniswap factory, collecting and aggregating data across pairs, tokens, transactions, and liquidity providers. It offers comprehensive insights, including individual and aggregated historical data, USD pricing, and day-by-day statistics across the platform. The subgraph features key entities like UniswapFactory, Token, Pair, Transaction, Mint, Burn, and Swap, each storing specific metrics—such as total liquidity, all-time volume, and transaction details—vital for developers and analysts. Users can perform sophisticated data queries either locally, after configuring the package.json settings to point to a personal graph account, or via The Graph Explorer playground. These queries unlock extensive data filtering possibilities, offering granular views of Uniswap’s usage and performance.
