The exploiter of Solana-based DeFi lending platform Mango Markets has revealed his identity, referring to his actions as "a highly profitable trading strategy.”
Avraham Eisenberg, who calls himself a "digital art dealer," has revealed that he was behind the $100 million exploit that hit Mango Markets earlier last week. "I was involved with a team that operated a highly profitable trading strategy last week," he said in a Saturday tweet.
In his admission, Eisenberg argued that their "actions were legal open market actions, using the protocol as designed, even if the development team did not fully anticipate all the consequences of setting parameters the way they are.”
However, as a result of the exploit, Mango Markets became insolvent, Eisenberg noted, adding that the insurance fund was also insufficient to cover all liquidations. This led to the loss of over $100 million in user funds.
"To remedy the situation, I helped negotiate a settlement agreement with the insurance fund with the goal of making all users whole as soon as possible as well as recapitalizing the exchange," he said.
Eisenberg compared the process to how auto deleveraging works on exchanges, which is a risk management mechanism used when a position is closed with negative equity and claws back some profits from profitable traders in order to ensure all users funds are protected.
Mango Markets is a decentralized exchange (DEX) on the Solana blockchain. MNGO, the protocol’s governance token, is a relatively little-known token with a market capitalization of just over $26.8 million.
As reported, the exploiter funded an account with the stablecoin USDC, and later took what was described as an “outsized position” on the Mango token perpetual futures market
