James and Anton Peraire-Bueno, MIT graduates, are facing trial in Manhattan federal court in the first criminal case involving a crypto sandwich attack. The brothers are accused of using MEV strategies to steal $25 million from traders on the Ethereum blockchain. They allegedly exploited a vulnerability in the MEV Boost software to reorder transactions for profit. The case has ignited debate over the legality and ethics of MEV practices in the crypto industry. The outcome could set a significant precedent for how such strategies are addressed under U.S. law.
