Introduction dDemeter-fetch is a member of the demeter family, which is responsible for fetching and processing on-chain data. It provides standardized data for backtesting and defi research. Demeter-fetch can fetch chain event logs of DEFI projects from various sources and convert them into a unified format. In the project dimension, it supports Uniswap and AAVE. In the data source dimension, the supported data sources include: RPC: Standard RPC interface of evm chains.
