Value DeFi (formerly YFValue/YFV) was a yield aggregation and AMM protocol on Ethereum and Binance Smart Chain that suffered three exploits between November 2020 and May 2021, with combined losses of roughly $21 to $28 million depending on the source. It had advertised flash loan protection the day before the first attack, and was alleged to have used a paid Fiverr actress as a fictitious co-founder 'Anna Tanaka'. The team is anonymous, only $2 million was returned, and the VALUE token is effectively defunct.
