Documented cause
Mango Markets was a decentralized exchange and margin trading platform on Solana. In October 2022, trader Avraham Eisenberg executed what he called a 'highly profitable trading strategy' but federal prosecutors called market manipulation. He used two accounts to artificially inflate the price of MANGO tokens 5x within minutes, then used his artificially inflated MANGO collateral to borrow $117 million in real assets from the Mango treasury. He then submitted a governance proposal to give him immunity from prosecution in exchange for returning $67 million, keeping $47 million as a 'bug bounty'. The community approved it. Eisenberg was later arrested and convicted of wire fraud and commodity manipulation — proving that blockchain governance cannot override federal law.
Lesson
“DeFi governance that can vote to approve fund transfers is also governance that can vote to approve fraudulent fund transfers. Eisenberg used the protocol's own rules against it. The community had a choice between getting some money back and letting him go — federal law made that choice irrelevant.”
