The Pump.fun and Solana Lawsuit: A Wake-Up Call for Blockchain Infrastructure Liability

The Pump.fun and Solana lawsuit, now a $5.5 billion RICO class-action case, has escalated into one of the most consequential legal battles in crypto history. At its core, the case challenges the liability of blockchain infrastructure providers for enabling speculative token schemes that allegedly exploit retail investors. For investors, this lawsuit underscores a critical question: Can platforms like Solana Labs and Jito Labs be held legally accountable for facilitating unregulated financial activity, even if they do not directly issue tokens? The answer, as courts deliberate, could redefine the legal and regulatory landscape for blockchain ecosystems.

A Legal Framework Under Scrutiny

The plaintiffs' expanded complaint, approved by a U.S. federal judge in December 2025, alleges that Solana Labs, the Solana Foundation, Jito Labs, and key executives formed a "Crypto Crime Cartel" to manipulate token launches on the Pump.fun platform. According to nearly 5,000 internal chat logs from a confidential source, these entities allegedly coordinated to prioritize insiders in transaction processing, enabling front-running and price manipulation. The lawsuit argues that Solana's fast, low-cost infrastructure-combined with Jito's MEV (Miner Extractable Value) tools-created an environment where retail investors lost 99.6% of their capital across over 50,000 tokens, while Pump.fun retained a 1% fee on all transactions.

This case hinges on two legal pillars: RICO statutes, which target organized schemes to defraud, and securities law, which questions whether memecoins qualify as unregistered securities. While the U.S. Securities and Exchange Commission (SEC) has publicly stated that memecoins do not fall under federal securities laws, courts retain the authority to independently define securities. If the plaintiffs succeed, the precedent could force blockchain platforms to implement stricter compliance measures or face liability as "joint issuers" of tokens they facilitate according to legal experts.
