A federal judge in New York has granted plaintiffs permission to file a Second Amended Complaint in the class-action lawsuit against Solana-based launchpad Pump.fun, significantly raising the stakes for the Solana ecosystem. The ruling by Judge Colleen McMahon, filed December 9 and unsealed this week, admits approximately 5,000 internal chat logs allegedly provided by a confidential informant. Evidence plaintiffs claim proves a "coordinated racketeering enterprise."
The "Digital Casino" Allegations
The consolidated case, Aguilar v. Baton Corporation Ltd. et al., has evolved from a standard unregistered securities claim into a RICO (Racketeer Influenced and Corrupt Organizations) suit. Plaintiffs allege that Pump.fun, in concert with Solana infrastructure providers, operated a rigged system that functioned less like a marketplace and more like a "digital casino" with predetermined winners.
New evidence purportedly reveals that Solana Labs and Jito Labs personnel were not merely neutral service providers but active participants. The complaint argues that Jito’s transaction-ordering tools (MEV) and Solana’s validator architecture were exploited to grant insiders milliseconds of priority access. This allowed them to front-run retail buyers at the bonding curve’s inception, the exact moment of lowest liquidity and highest potential upside.
"What appeared to be a fair, automated marketplace was, Plaintiffs say, structurally tilted to extract value from ordinary users while rewarding those with privileged access to Solana’s infrastructure and Jito Lab’s transaction ordering tools."
The Evidence: 5,000 Chat Logs
The pivot in the case hinges on a confidential informant who reportedly "re-contacted" legal counsel in September 2025 after a period of silence. The informant provided a cache of ~5,000 messages involving Pump.fun executives and engineers across the Solana stack. These logs allegedly document:
- Coordination on token launches to ensure insider entry.
- Specific discussions on tweaking validator parameters to favor specific wallets.
- Knowledge that the "fair launch" marketing was deceptive.
This development potentially complicates the legal standing of Jito Labs, which secured a voluntary dismissal of prior claims in late September. The admission of new evidence involving Jito personnel suggests the plaintiffs intend to re-litigate the infrastructure provider’s liability under the RICO statute.
Market Reaction
Solana (SOL) reacted negatively to the headline risk, sliding 1.7% to trade around $127.30. While the network remains robust, the lawsuit attacks the legal immunity of the "neutral infrastructure" thesis that underpins much of the L1’s DeFi value proposition. If validators and MEV providers can be held liable as RICO co-conspirators, the compliance burden for the entire Solana validator set could skyrocket.
