Pump.fun Lawsuit Expands as New Evidence Revives MEV Debate

2025/12/19 15:33

A US court is once again being asked to weigh in on maximal extractable value practices after a judge allowed new evidence to be added to a class-action lawsuit tied to a memecoin platform.

Key Takeaways

  • A judge has allowed new evidence to be added to a class-action lawsuit involving Pump.fun, Solana Labs, the Solana Foundation, and Jito
  • The new filing includes thousands of internal chat logs allegedly detailing coordination around MEV practices
  • The case could influence how U.S. courts approach MEV-related disputes in crypto markets

The judge granted a motion to amend and refile to include new evidence a class-action lawsuit against memecoin launch platform Pump.fun, the maximal extractable value (MEV) infrastructure company Jito Labs, the Solana Foundation, which is the nonprofit organization behind the Solana ecosystem, and others.

The motion said over 5,000 pieces of evidence in the form of internal chat logs were submitted by a “confidential informant” in September that were previously unavailable. The filing said:

“Plaintiffs assert that the logs contain contemporaneous discussions among Pump.fun, Solana Labs, Jito Labs, and others concerning the alleged scheme, and that they materially clarify the enterprise’s management, coordination, and communications.”

The lawsuit, originally filed in July, alleges that the Pump.fun platform deliberately misled retail investors by marketing memecoin launches as “fair,” but engaged in a scheme with Solana validators to front-run retail participants through maximal extractable value (MEV).

Allegations of Insider Advantage Through MEV

Maximal extractable value is a technique that involves reordering transactions within a block to maximize profit for MEV arbitrageurs and validators.

The plaintiffs allege that Pump.fun used MEV techniques to give insiders preferential access to new tokens at a low value, which were then pumped and dumped onto retail participants, who were used as exit liquidity by insiders.

The lawsuit could set a precedent for MEV cases in the United States, as the ethics of the practice continue to be debated within the crypto industry and legal bodies struggle to define proper regulations about the highly technical subject.

Anton and James Peraire-Bueno, the brothers accused of using a MEV trading bot to make millions of dollars in profit, went to trial in November in the US.

Prosecutors argued that the brothers tricked victims out of their funds, but defense attorneys said that they were executing a legitimate trading strategy and did not do anything illegal.

The jury struggled to reach a verdict in the case, and several jurors requested additional information to clarify the complexities surrounding the technical specifics of blockchain technology.

The case ended in a mistrial after the jury was deadlocked and failed to reach a verdict, highlighting the complexity of adjudicating legal disputes surrounding the application of nascent financial technology.

(Photo by Paul Natkin/Getty Images) Getty Images Singer Lou Gramm has a vivid memory of recording the ballad “Waiting for a Girl Like You” at New York City’s Electric Lady Studio for his band Foreigner more than 40 years ago. Gramm was adding his vocals for the track in the control room on the other side of the glass when he noticed a beautiful woman walking through the door. “She sits on the sofa in front of the board,” he says. “She looked at me while I was singing. And every now and then, she had a little smile on her face. I’m not sure what that was, but it was driving me crazy. “And at the end of the song, when I’m singing the ad-libs and stuff like that, she gets up,” he continues. “She gives me a little smile and walks out of the room. And when the song ended, I would look up every now and then to see where Mick [Jones] and Mutt [Lange] were, and they were pushing buttons and turning knobs. They were not aware that she was even in the room. So when the song ended, I said, ‘Guys, who was that woman who walked in? She was beautiful.’ And they looked at each other, and they went, ‘What are you talking about? We didn’t see anything.’ But you know what? I think they put her up to it. Doesn’t that sound more like them?” “Waiting for a Girl Like You” became a massive hit in 1981 for Foreigner off their album 4, which peaked at number one on the Billboard chart for 10 weeks and…

New York Regulators Push Banks to Adopt Blockchain Analytics

New York Regulators Push Banks to Adopt Blockchain Analytics

New York’s top financial regulator urged banks to adopt blockchain analytics, signaling tighter oversight of crypto-linked risks. The move reflects regulators’ concern that traditional institutions face rising exposure to digital assets. While crypto-native firms already rely on monitoring tools, the Department of Financial Services now expects banks to use them to detect illicit activity. NYDFS Outlines Compliance Expectations The notice, issued on Wednesday by Superintendent Adrienne Harris, applies to all state-chartered banks and foreign branches. In its industry letter, the New York State Department of Financial Services (NYDFS) emphasized that blockchain analytics should be integrated into compliance programs according to each bank’s size, operations, and risk appetite. The regulator cautioned that crypto markets evolve quickly, requiring institutions to update frameworks regularly. “Emerging technologies introduce evolving threats that require enhanced monitoring tools,” the notice stated. It stressed the need for banks to prevent money laundering, sanctions violations, and other illicit finance linked to virtual currency transactions. To that end, the Department listed specific areas where blockchain analytics can be applied: Screening customer wallets with crypto exposure to assess risks. Verifying the origin of funds from virtual asset service providers (VASPs). Monitoring the ecosystem holistically to detect money laundering or sanctions exposure. Identifying and assessing counterparties, such as third-party VASPs. Evaluating expected versus actual transaction activity, including dollar thresholds. Weighing risks tied to new digital asset products before rollout. These examples highlight how institutions can tailor monitoring tools to strengthen their risk management frameworks. The guidance expands on NYDFS’s Virtual Currency-Related Activities (VCRA) framework, which has governed crypto oversight in the state since 2022. Regulators Signal Broader Impact Market observers say the notice is less about new rules and more about clarifying expectations. By formalizing the role of blockchain analytics in traditional finance, New York is reinforcing the idea that banks cannot treat crypto exposure as a niche concern. Analysts also believe the approach could ripple beyond New York. Federal agencies and regulators in other states may view the guidance as a blueprint for aligning banking oversight with the realities of digital asset adoption. For institutions, failure to adopt blockchain intelligence tools may invite regulatory scrutiny and undermine their ability to safeguard customer trust. With crypto now firmly embedded in global finance, New York’s stance suggests that blockchain analytics are no longer optional for banks — they are essential to protecting the financial system’s integrity.
