Summary
Akropolis is an Ethereum-based DeFi protocol founded in 2017 by Ana Andrianova and Kate Kurbanova, offering yield aggregation and undercollateralized lending through its Delphi and Sparta products. On November 12, 2020, the protocol suffered a $2.03 million DAI exploit via a reentrancy and flash loan attack — a vulnerability that was missed across multiple third-party smart contract audits. The project subsequently rebranded to Kaon in early 2025, having never recovered the stolen funds or fully compensated affected users.
