Data Mining of Uniswap Decentralized Exchange

Abstract

The data from decentralized finance services is openly available once they operate in public blockchains. Although data encryption techniques for transaction exist, they are challenging, increase costs and decrease trust. Therefore, everyone can use the DeFi data. Natively, the data is stored as a transaction log, where we have a byte code of contracts and history of their method calls with parameters. So the problem is to represent it conveniently for analysis. In the paper, we consider a decentralized exchange called UniSwap, overview its operation principles, create a database with the related data and share scripts with the elementary examples. The results help overcome the entering threshold for further data analysis.
