Aave purchases 2.7M CRV to clear bad debt following failed Eisenberg attack

According to a new post on Jan. 26, Marc Zeller integrations lead at decentralized finance (DeFi) lending protocol Aave stated that the firm purchased 2.7 million Curve (CRV) tokens which would clear "excessive remaining bad debt" within the next 15 hours over a dozen transactions. The move follows the community approval of Aave Improvement Protocol (AIP) 144, which deployed a swap contract that acquires 2,700,000 units of CRV, with a USDC spend limit of $3,105,000 and max unit value of $1.15 per CRV token.

The bad debt on the Aave protocol resulted from a sophisticated exploit that took place on Nov. 23. Avaraham Eisenberg, who previously drained DeFi protocol Mango Markets and caused $47 million in net damages, took on a series of heavy volume short CRV positions on Aave in an attempt to orchestrate a short squeeze and force developers to buyback his positions at upwards of 100% slippage due to lack of liquidity.

However, it turned out Aave had much more liquidity than anticipated, and Eisenberg reportedly lost $10 million on the trade. Nevertheless, some slippage occurred as a result of the incident, and Aave was left with a total of 2.656 million CRV in bad debt while liquidating Eisenberg's positions. 

The same day, Mango Markets filed a lawsuit against Avraham Eisenberg, asking the court to rescind its $47 million bounty agreement with the hacker for his role in the $117 million exploit on Oct. 12, 2022. The U.S. Securities and Exchange Commission has charged Eisenberg with stealing $117 million in digital assets. Eisenberg was arrested in Puerto Rico by the FBI on Dec. 27, 2022, on charges of commodities manipulation and commodities fraud.
