Jito Labs
Summary
Jito Labs is a San Francisco-based software company that builds MEV (maximal extractable value) and liquid staking infrastructure for the Solana blockchain, most notably the Jito-Solana validator client and the JitoSOL liquid staking protocol. The company was named as a defendant in a civil RICO class action (Aguilar v. Baton Corporation, S.D.N.Y., No. 1:25-cv-00880) alleging it enabled insider front-running on the Pump.fun memecoin platform; plaintiffs voluntarily dismissed all claims against Jito Labs on September 26, 2025, without settlement payment, though the court later granted leave to refile and the broader case against co-defendants continues. Jito Labs previously suspended its public mempool in March 2024 after sandwich-attack bots exploited the feature, and subsequently took enforcement action against validators conducting such attacks in 2025.
