{"investigation":{"slug":"mango-markets","entity_name":"Mango Markets","trust_score":12,"severity_base":null,"score_modifier":0,"confidence":0.92,"status":"published","content_type":"investigation","summary":"Mango Markets was a Solana-based decentralized trading platform offering spot trading, perpetual futures, and lending with cross-margining. In October 2022, trader Avraham Eisenberg executed an oracle manipulation attack, draining approximately $116–117 million from the protocol through artificially inflated MNGO collateral. The protocol subsequently faced enforcement actions from the DOJ, SEC, and CFTC, settled with regulators in 2024, and formally shut down in January 2025.","sections":[{"content":"Mango Markets was a decentralized exchange (DEX) built on the Solana blockchain, offering spot trading, perpetual futures contracts, and a borrow-lending market with cross-margin capabilities. Its native governance token, MNGO, was used for protocol voting and served as collateral within the platform. The protocol raised more than $70 million through MNGO token sales beginning in August 2021, according to the SEC. At its peak in November 2021, Mango Markets reported a total value locked (TVL) of approximately $210 million. The platform was affiliated with Blockworks Foundation and Mango Labs LLC, with a decentralized autonomous organization (DAO) responsible for governance decisions. The protocol officially wound down all operations on January 13, 2025, following regulatory settlements and internal disputes among contributors.","heading":"Protocol Overview","sources":[{"url":"https://defillama.com/protocol/mango-markets","name":"defillama.com","type":"other","credibility":3},{"url":"https://www.sec.gov/newsroom/press-releases/2024-154","name":"sec.gov","type":"other","credibility":3},{"url":"https://www.theblock.co/post/334172/mango-markets-to-wind-down-in-wake-of-sec-settlement-dao-battle","name":"theblock.co","type":"other","credibility":3}],"severity":"medium"},{"content":"On October 11, 2022, Avraham Eisenberg executed a large-scale oracle manipulation attack against Mango Markets that drained approximately $116 million in user deposits within approximately 40 minutes. Eisenberg deposited USDC into two separate anonymous accounts on the platform and used one account to short 483 million MNGO perpetual futures contracts while using the other account to take the long side of the same trade, establishing an offsetting leveraged position at minimal cost. Eisenberg then purchased approximately $4 million worth of MNGO tokens across three separate spot exchanges — Ascendex, FTX, and Gate.io — which served as the oracle inputs for Mango Markets' price feed (powered by the Pyth Network). This buying activity drove the reported MNGO price from approximately $0.038 to a peak of approximately $0.91, a rise of more than 2,300 percent within a 30-minute window, according to analysis by Solidus Labs. The artificial price spike caused the paper value of Eisenberg's long perpetual position to inflate dramatically. He then used this inflated collateral value to borrow and withdraw virtually all liquid assets from Mango Markets' lending pools, including USDC, SOL, BTC, USDT, and other tokens. Because the borrowed assets were denominated in tokens that retained real-world value while his collateral — the inflated MNGO position — subsequently collapsed, the loans were effectively never repayable, and the protocol's treasury was left insolvent. The Pyth oracle itself functioned as designed; the vulnerability arose from the protocol's exposure to a thinly traded asset as primary collateral.","heading":"October 2022 Oracle Manipulation Exploit","sources":[{"url":"https://www.soliduslabs.com/post/mango-hack","name":"soliduslabs.com","type":"other","credibility":3},{"url":"https://www.coindesk.com/markets/2022/10/12/how-market-manipulation-led-to-a-100m-exploit-on-solana-defi-exchange-mango","name":"coindesk.com","type":"other","credibility":3},{"url":"https://www.cftc.gov/PressRoom/PressReleases/8647-23","name":"cftc.gov","type":"other","credibility":3},{"url":"https://immunebytes.com/blog/mango-markets-exploit-oct-11-2022-detailed-analysis/","name":"immunebytes.com","type":"other","credibility":3}],"severity":"medium"},{"content":"In the days following the exploit, Eisenberg publicly claimed on Twitter that he had been involved with a team that executed a 'highly profitable trading strategy' and described his actions as 'legal open market actions, using the protocol as designed.' He proposed a settlement through the Mango Markets governance forum: he would return approximately $67 million of the stolen funds in exchange for keeping $47 million as a self-described 'bug bounty' and a commitment from the Mango DAO not to pursue criminal charges. A governance vote was held on October 15, 2022, and approximately 98 percent of voting token holders — representing 291 million MNGO tokens — approved the deal. Critics noted the $47 million retention was far above the industry norm of approximately 10 percent for bug bounties, and legal analysts questioned whether a DAO could contractually bind members to decline cooperation with law enforcement. Mango Labs subsequently filed a civil lawsuit seeking to void this agreement and recover the remaining $47 million plus interest.","heading":"Post-Exploit DAO Settlement with Eisenberg","sources":[{"url":"https://cointelegraph.com/news/mango-market-s-dao-forum-set-to-approve-47m-settlement-with-hacker","name":"cointelegraph.com","type":"other","credibility":3},{"url":"https://mcmillan.ca/insights/part-2-of-mcmillan-series-defi-platform-mango-loses-117-million-in-smart-contract-exploit-is-mangos-settlement-with-the-exploiter-enforceable-and-what-does-it-mean-for-daos/","name":"mcmillan.ca","type":"other","credibility":3},{"url":"https://decrypt.co/120054/mango-labs-sues-avraham-eisenberg-mango-markets-exploit","name":"decrypt.co","type":"other","credibility":3}],"severity":"medium"},{"content":"On December 23, 2022, the U.S. Department of Justice filed a criminal complaint in the Southern District of New York charging Eisenberg with commodities fraud, commodities manipulation, and wire fraud. A federal grand jury returned an indictment on the same three counts on January 9, 2023. Eisenberg was arrested in Puerto Rico in December 2022. Following a nine-day trial in April 2024, a jury convicted Eisenberg on all three counts. The DOJ described the scheme as involving the artificial inflation of MNGO's oracle-reported price by over 1,300 percent in a 30-minute window, enabling the withdrawal of more than $110 million in crypto assets. However, in May 2025, U.S. District Judge Arun Subramanian vacated all three criminal convictions on Eisenberg's Rule 29 motion for acquittal. The judge found that the government had failed to establish proper venue in the Southern District of New York because Eisenberg executed all transactions from Puerto Rico and had no contact with New York in connection with the scheme. Additionally, the wire fraud conviction was overturned on the grounds that Mango Markets had no terms of service and no prohibition against manipulation, meaning Eisenberg made no materially false statement sufficient to constitute fraud under the applicable legal standard. Federal prosecutors subsequently appealed the acquittal.","heading":"Criminal Charges: DOJ Indictment and Trial","sources":[{"url":"https://www.justice.gov/archives/opa/pr/man-convicted-110m-cryptocurrency-scheme","name":"justice.gov","type":"other","credibility":3},{"url":"https://www.trmlabs.com/resources/blog/breaking-federal-judge-overturns-all-criminal-convictions-in-mango-markets-case-against-avraham-eisenberg","name":"trmlabs.com","type":"other","credibility":3},{"url":"https://www.theblock.co/post/355666/u-s-judge-overturns-fraud-convictions-of-mango-markets-exploiter-eisenberg-determining-improper-venue","name":"theblock.co","type":"other","credibility":3},{"url":"https://www.dlnews.com/articles/defi/prosecutors-appeal-acquittal-of-mango-markets-exploiter/","name":"dlnews.com","type":"other","credibility":3}],"severity":"medium"},{"content":"On January 9, 2023, the CFTC filed civil charges against Eisenberg in SDNY, alleging a manipulative and deceptive scheme to misappropriate more than $110 million from Mango Markets. The CFTC characterized the action as its first enforcement action involving oracle manipulation on a decentralized exchange platform. On January 20, 2023, the SEC separately charged Eisenberg under anti-fraud and market manipulation provisions of securities law, characterizing MNGO as a security. In September 2024, the SEC filed settled charges against Mango DAO, Blockworks Foundation, and Mango Labs LLC for the unregistered offer and sale of MNGO tokens and for operating as an unregistered broker. The SEC alleged that the entities raised more than $70 million through unregistered MNGO sales beginning in August 2021. The respondents agreed to pay a combined $700,000 civil penalty, destroy their MNGO token holdings, and seek delisting of MNGO from trading platforms, without admitting or denying the charges. Also in September 2024, Mango DAO voted on a proposed $500,000 settlement with the CFTC related to allegations that the platform failed to register as a commodities exchange, offered services to U.S. customers without proper licensing, and failed to verify customer identities. Combined regulatory penalties against Mango-affiliated entities approached approximately $1.2 million.","heading":"SEC and CFTC Enforcement Actions","sources":[{"url":"https://www.cftc.gov/PressRoom/PressReleases/8647-23","name":"cftc.gov","type":"other","credibility":3},{"url":"https://www.sec.gov/newsroom/press-releases/2023-13","name":"sec.gov","type":"other","credibility":3},{"url":"https://www.sec.gov/newsroom/press-releases/2024-154","name":"sec.gov","type":"other","credibility":3},{"url":"https://www.coindesk.com/policy/2024/09/27/mango-markets-agrees-to-destroy-mngo-tokens-in-sec-settlement","name":"coindesk.com","type":"other","credibility":3},{"url":"https://cointelegraph.com/news/mango-markets-contemplates-six-figure-settlement-with-cftc","name":"cointelegraph.com","type":"other","credibility":3}],"severity":"medium"},{"content":"During the investigation into the Mango Markets exploit, law enforcement discovered child sexual abuse material (CSAM) in connection with Eisenberg's arrest.

This sentence was imposed independently of the crypto-related charges, which were vacated by Judge Subramanian in May 2025.

The protocol attempted to resume operations after the exploit but faced continued regulatory scrutiny from both the SEC and CFTC. In early January 2025, co-founder Maximilian Schneider disclosed on Discord that contributors wished to discontinue work on the project. Mango Markets formally wound down all operations — including trading, lending, and borrowing — on January 13, 2025. As part of the SEC settlement, all MNGO tokens held by DAO-affiliated entities were destroyed and the token was requested to be delisted from exchanges. The case established significant legal precedent regarding the applicability of traditional fraud statutes to DeFi oracle manipulation, the enforceability of DAO-mediated settlements, and venue requirements for decentralized finance crimes.
