Ethereum MEV Attack Ends in Mistrial as New York Federal Court Splits Verdict in Peraire-Bueno Brothers Trial

COINOTAG News, citing Cointelegraph, reports that a New York federal court declared a mistrial in the case of brothers Anton and James Peraire-Bueno after jurors failed to reach a unanimous verdict. The three‑week proceedings centered on a 2023 Ethereum MEV attack that prosecutors say yielded about $25 million in roughly 12 seconds. Authorities characterized the episode as a bait-and-switch scheme involving fraud and money laundering, while the defense framed the activity as on‑chain front-running within game-like trading dynamics.

Analysts note the mistrial underscores the challenge of applying traditional criminal standards to rapid, automated activity on the Ethereum network. With liability unresolved and a potential retrial, observers will monitor regulatory and risk-management implications for crypto markets and DeFi infrastructure as this case unfolds.
