This project is for curious minds interested in understanding popular Ethereum-based application vulnerabilities that are particularly effective in decentralized financial (DeFi) markets. In this project, we will execute a few exploits within a few example smart contracts on a blockchain we will deploy. By the end of this project, you should have hands-on experience and a firmer understanding of race conditions and other types of ecosystem manipulation measures that can occur in Ethereum-based decentralized financial (DeFi) markets. Ideal participants have a basic understanding of how Ethereum works and some experience executing Ethereum transactions.
