Solana MEV Sandwich Bots
Auto-generated score, not yet verified against the scoring model. Under review — treat as indicative, not a verdict.
anchored·2gVac5…oEAqSummary
Solana MEV sandwich bots are automated programs that exploit Solana's transaction ordering mechanisms to front-run and back-run retail user trades, extracting an estimated $370 million to $500 million from users between January 2024 and May 2025. The practice has drawn enforcement responses from the Solana Foundation, Jito Labs, and Marinade Finance, and is the subject of an active federal class-action lawsuit in the Southern District of New York naming Pump.fun, Solana Labs, and related entities. While coordinated countermeasures reduced attack profitability by an estimated 60-70% in 2025, attacks continue and disproportionately harm memecoin traders using high slippage settings on Raydium and Pump.fun.
