Plaintiffs' counsel described the material as containing \"multiple direct communications\" in which engineers from Solana Labs and Pump.fun discussed \"integration of key software components,\" and the amended complaint characterized the logs as showing contemporaneous discussions among Pump.fun, Solana Labs, Jito Labs and others about an alleged scheme to give insiders preferential, faster access to new memecoin tokens via MEV techniques before retail buyers could trade them. The suit alleges this amounted to a \"coordinated racketeering enterprise\" and an \"insider-rigged casino,\" claims roughly 60% of retail investors lost money, and estimates combined losses that may exceed $4 billion. The identity of the informant, and the chat logs themselves, have not been made public, so the content described above is known only through the plaintiffs' characterizations in court filings and statements to reporters, not from the primary documents.","heading":"The alleged 5,000-message leak and the MEV class action","severity":"high","sources":[{"credibility":2,"name":"DL News — \"Solana execs sued over memecoin trades\"","type":"news_article","url":"https://www.dlnews.com/articles/defi/solana-execs-sued-over-memecoin-trades/"},{"credibility":2,"name":"Cointelegraph — \"MEV trading returns to court in Pump.fun class-action lawsuit\"","type":"news_article","url":"https://cointelegraph.com/news/mev-trading-returns-court-pump-fun-class-action-lawsuit"},{"credibility":2,"name":"Unchained — \"MEV lawsuit against Pump.fun and Solana heats up\"","type":"news_article","url":"https://unchainedcrypto.beehiiv.com/p/mev-lawsuit-against-pump-fun-and-solana-escalates"},{"credibility":2,"name":"Cryptonews — \"Whistleblower Drops 5,000+ Secret Chats in Pump.fun MEV Scandal\"","type":"news_article","url":"https://cryptonews.com/news/pumpfun-mev-scandal-leaks-lawsuit/"}]},{"content":"U.S. District Judge Colleen McMahon presided over the case. According to DL News, on December 11, 2025 she approved plaintiff Michael Okafor's request to file an amended complaint incorporating the new chat-log evidence, with a filing deadline of January 7, 2026; Cointelegraph's reporting described a comparable ruling allowing amendment of the complaint around the same period, though outlets differ on whether the order issued December 9 or December 11, and on whether the refiling deadline was January 7 or an alternate date reported elsewhere as December 19 with motions to dismiss due January 23, 2026. The underlying lawsuit was originally filed in July 2025. Jito Labs, the Jito Foundation, and their executives were dropped from the suit without prejudice in September 2025, before the chat-log evidence surfaced. The court reportedly rejected a plaintiffs' request to submit some of the new material under seal and outside the defendants' view, citing fairness and transparency concerns.","heading":"Court proceedings and ruling allowing the amended complaint","severity":"high","sources":[{"credibility":2,"name":"DL News — \"Solana execs sued over memecoin trades\"","type":"news_article","url":"https://www.dlnews.com/articles/defi/solana-execs-sued-over-memecoin-trades/"},{"credibility":2,"name":"Cointelegraph — \"MEV trading returns to court in Pump.fun class-action lawsuit\"","type":"news_article","url":"https://cointelegraph.com/news/mev-trading-returns-court-pump-fun-class-action-lawsuit"}]},{"content":"Pump.fun, in its motion to dismiss, argued the complaint identifies no presales, no insider token allocations, and no rug pulls, and characterized the plaintiffs' fairness claims as \"non-actionable puffery.\" Jito argued its MEV-related software predates Pump.fun, was available to any market participant, and compared imposing liability on it to holding modem manufacturers liable for third parties' use of the internet; Jito and Pump.fun jointly argued the complaint offers no proof of coordination and that shared investors between the companies do not establish an interpersonal relationship supporting the racketeering claim. No statements from Solana Labs or the Solana Foundation were found in available reporting. Delphi Ventures founding partner Tommy Shaughnessy publicly called the suit \"dumb and frivolous,\" characterizing it as mischaracterizing standard, neutral MEV infrastructure as a secret \"inside lane,\" and some Solana-affiliated attorneys reportedly expressed skepticism the case would survive judicial scrutiny. Cointelegraph reported it contacted Burwick Law, Pump.fun, Jito Labs, and the Solana Foundation for comment on the chat-log allegations specifically and received no responses by publication.","heading":"Responses and denials from Pump.fun, Jito, and Solana","severity":"medium","sources":[{"credibility":2,"name":"DL News — \"Solana execs sued over memecoin trades\"","type":"news_article","url":"https://www.dlnews.com/articles/defi/solana-execs-sued-over-memecoin-trades/"},{"credibility":2,"name":"Cointelegraph — \"MEV trading returns to court in Pump.fun class-action lawsuit\"","type":"news_article","url":"https://cointelegraph.com/news/mev-trading-returns-court-pump-fun-class-action-lawsuit"}]},{"content":"As of the most recent reporting found, the alleged 5,000-message chat archive has not been published or independently reviewed by journalists; all public characterizations of its contents originate from plaintiffs' counsel. At least one outlet (MEXC) reported in December 2025 that it could not find verified evidence substantiating the 5,000-secret-chats claim as of that date. A separate annual-review article (HTX) cited a figure of approximately 15,000 internal messages from Pump.fun, Solana, and Jito — three times the figure reported elsewhere — raising further doubt about the precision of the publicly reported message count. Given that the primary documents remain non-public and sourcing is secondary throughout, the specific allegations attributed to the chat logs should be treated as alleged and unverified pending release of the underlying material or further court proceedings.","heading":"Unverified status of the leak and disputed message count","severity":"medium","sources":[{"credibility":3,"name":"MEXC News coverage of the Pump.fun MEV scandal leaks (archived via search)","type":"news_article","url":"https://www.mexc.com/news/301169"},{"credibility":3,"name":"HTX — \"Pump.fun Lawsuit Annual Review: Mysterious Informant, Internal Records\"","type":"news_article","url":"https://www.htx.com/news/pumpfun-lawsuit-annual-review-mysterious-informant-internal-2uSbSAra/"}]},{"content":"A distinct and unrelated disclosure occurred in March 2026. Jarett Dunn, a former Pump.fun developer who went by the handle \"STACCoverflow,\" had allegedly used insider access and a flash loan in May 2024 to drain approximately $1.9–2 million in SOL and meme coins from Pump.fun's bonding curves, afterward distributing the funds to thousands of wallets and describing the act as a protest against the platform's effect on retail traders. UK authorities arrested Dunn in London shortly after the exploit. He signed documents admitting guilt to fraud-related charges in August 2025, attempted to withdraw that plea in October 2025, and was sentenced by a UK court to six years in prison in December 2025. On March 3, 2026, two days before (per one account) or around the time of his sentencing process, Dunn published private internal Telegram chats and his Pump.fun employment contract, stating he was acting as a whistleblower over safety concerns. According to available reporting, these chats did not reveal deliberate market manipulation or fee misconduct; instead they reportedly concerned internal operational issues, including the platform's alleged failure to implement KYC/AML measures for its livestreaming features. This leak is separate from, and did not corroborate, the September 2025 confidential-informant leak cited in the MEV class action.","heading":"Separate, unrelated 2026 leak by convicted former developer Jarett Dunn","severity":"medium","sources":[{"credibility":2,"name":"HTX — \"Stole $2 Million from pump.fun, Sentenced to 6 Years in Prison, He Chose to 'Self-Destruct'\"","type":"news_article","url":"https://www.htx.com/news/stole-2-million-from-pumpfun-sentenced-to-6-years-in-prison-B1jsYsVH/"},{"credibility":3,"name":"Our Crypto Talk — coverage of Jarett Dunn Pump.fun chat leaks","type":"news_article","url":"https://ourcryptotalk.com/news/slug-pump-fun-chat-leaks-jarett-dunn"}]}],"sources_used":[{"credibility":2,"name":"DL News — \"Solana execs sued over memecoin trades\"","type":"news_article","url":"https://www.dlnews.com/articles/defi/solana-execs-sued-over-memecoin-trades/"},{"credibility":2,"name":"Cointelegraph — \"MEV trading returns to court in Pump.fun class-action lawsuit\"","type":"news_article","url":"https://cointelegraph.com/news/mev-trading-returns-court-pump-fun-class-action-lawsuit"},{"credibility":2,"name":"Unchained — \"MEV lawsuit against Pump.fun and Solana heats up\"","type":"news_article","url":"https://unchainedcrypto.beehiiv.com/p/mev-lawsuit-against-pump-fun-and-solana-escalates"},{"credibility":2,"name":"Cryptonews — \"Whistleblower Drops 5,000+ Secret Chats in Pump.fun MEV Scandal\"","type":"news_article","url":"https://cryptonews.com/news/pumpfun-mev-scandal-leaks-lawsuit/"},{"credibility":3,"name":"MEXC News coverage of the Pump.fun MEV scandal leaks","type":"news_article","url":"https://www.mexc.com/news/301169"},{"credibility":3,"name":"HTX — \"Pump.fun Lawsuit Annual Review: Mysterious Informant, Internal Records\"","type":"news_article","url":"https://www.htx.com/news/pumpfun-lawsuit-annual-review-mysterious-informant-internal-2uSbSAra/"},{"credibility":2,"name":"HTX — \"Stole $2 Million from pump.fun, Sentenced to 6 Years in Prison, He Chose to 'Self-Destruct'\"","type":"news_article","url":"https://www.htx.com/news/stole-2-million-from-pumpfun-sentenced-to-6-years-in-prison-B1jsYsVH/"},{"credibility":3,"name":"Our Crypto Talk — coverage of Jarett Dunn Pump.fun chat leaks","type":"news_article","url":"https://ourcryptotalk.com/news/slug-pump-fun-chat-leaks-jarett-dunn"}],"summary":"A confidential informant who resurfaced in September 2025 allegedly supplied plaintiffs' counsel in a U.S. class-action lawsuit with more than 5,000 private chat logs said to document coordination between Pump.fun, Solana Labs, and Jito Labs personnel around maximal extractable value (MEV) practices on the Pump.fun memecoin platform. A U.S. District Court judge allowed the logs to be added to an amended complaint in December 2025. The underlying messages have not been made public, Pump.fun and Jito have disputed the characterization and moved to dismiss, and a separate, unrelated March 2026 leak of internal Telegram chats by a former Pump.fun developer convicted of a 2024 hack did not corroborate the MEV allegations.","timeline":[{"date":"2024-05","event":"Alleged Pump.fun bonding-curve exploit by former developer Jarett Dunn, draining an estimated $1.9–2 million in SOL and meme coins; Dunn is arrested in London shortly afterward.","source":"HTX","source_url":"https://www.htx.com/news/stole-2-million-from-pumpfun-sentenced-to-6-years-in-prison-B1jsYsVH/"},{"date":"2025-07","event":"Underlying MEV class-action lawsuit against Pump.fun, Solana Labs, the Solana Foundation and Jito Labs is filed in the Southern District of New York.","source":"DL News","source_url":"https://www.dlnews.com/articles/defi/solana-execs-sued-over-memecoin-trades/"},{"date":"2025-08","event":"Jarett Dunn signs documents admitting guilt to fraud-related charges over the 2024 exploit.","source":"HTX","source_url":"https://www.htx.com/news/stole-2-million-from-pumpfun-sentenced-to-6-years-in-prison-B1jsYsVH/"},{"date":"2025-09","event":"Jito Labs, the Jito Foundation, and their executives are dropped from the MEV lawsuit without prejudice; around the same period, a confidential informant said to have \"reappeared\" allegedly supplies plaintiffs with the chat-log archive later described as exceeding 5,000 messages.","source":"DL News","source_url":"https://www.dlnews.com/articles/defi/solana-execs-sued-over-memecoin-trades/"},{"date":"2025-10","event":"Dunn attempts to withdraw his guilty plea; his legal representation withdraws.","source":"Our Crypto Talk","source_url":"https://ourcryptotalk.com/news/slug-pump-fun-chat-leaks-jarett-dunn"},{"date":"2025-12","date_evidence":"On December 11, she approved Okafor's request to file an amended complaint","date_original":"2025-12-11","event":"Judge Colleen McMahon approves plaintiff Michael Okafor's request to file an amended complaint incorporating the leaked chat-log evidence.","source":"DL News","source_url":"https://www.dlnews.com/articles/defi/solana-execs-sued-over-memecoin-trades/"},{"date":"2025-12","event":"UK court sentences Jarett Dunn to six years in prison for the 2024 Pump.fun exploit.","source":"HTX","source_url":"https://www.htx.com/news/stole-2-million-from-pumpfun-sentenced-to-6-years-in-prison-B1jsYsVH/"},{"date":"2025-12","event":"Crypto trade press (Cointelegraph, Cryptonews, Unchained) report on the amended complaint and the more-than-5,000-message leak; Pump.fun, Jito, and allied counsel dispute coordination claims and move to dismiss.","source":"Cointelegraph","source_url":"https://cointelegraph.com/news/mev-trading-returns-court-pump-fun-class-action-lawsuit"},{"date":"2026-03-03","date_evidence":"On March 3, 2026, Dunn published private Telegram chats and his Pump.fun employment contract","event":"Jarett Dunn publicly releases internal Telegram chats and his Pump.fun employment contract, citing whistleblower safety concerns; the material does not corroborate the separate MEV insider-trading allegations.","source":"Our Crypto Talk","source_url":"https://ourcryptotalk.com/news/slug-pump-fun-chat-leaks-jarett-dunn"}]},"v":1}
