Summary
Value DeFi (formerly YFValue/YFV) was a DeFi yield aggregation and AMM protocol that suffered three documented security exploits between August 2020 and May 2021, resulting in combined losses of approximately $24 million. Beyond the technical failures, the project was found to have used a paid actress from Fiverr to impersonate a co-founder named 'Anna Tanaka,' raising severe concerns about team identity, transparency, and intent. The VALUE token is effectively defunct, trading at a fraction of a cent with a near-zero market cap.
