The U.S. Securities and Exchange Commission is also investigating self-confessed Mango Markets exploiter Avraham Eisenberg over his role in extracting $110 million from the decentralized protocol. 

Kristin Johnson, a Commodity Futures Trading Commission commissioner, noted the SEC's parallel investigation in a statement published Monday. The CFTC filed its charges against Eisenberg, alleging manipulation of the decentralized swaps markets.

Investigators allege he illegally manipulated the price of Mango's own token, MNGO, to make substantial illicit profits.
