MEV Brothers: ₱1.49B Ethereum Exploit Legal Daw After Mistrial
Dalawang MIT-educated na magkapatid ang nag-argue na legal ang kanilang ₱1.49 billion ($25 million) Ethereum exploit, citing ang acquittal ng isang DeFi trader bilang precedent. Nag-declare si US District Judge Jessica Clarke ng mistrial noong November 2024 after hindi maka-reach ng verdict ang jury matapos ang three weeks na trial.
Key Takeaway
Pwedeng mag-set ng precedent ang case kung ang pag-exploit ng DeFi design flaws ay hacking o clever trading lang.
Sinabi ng defense attorney na si Patrick Looby sa New York court nitong Friday na dapat i-dismiss ang ₱1.49 billion ($25 million) MEV scheme ng Peraire-Bueno brothers, pointing sa acquittal ni Avraham Eisenberg para sa similar DeFi exploit. Nilinlang ni Eisenberg ang Mango Markets na magpahiram ng millions laban sa walang kwentang collateral through pag-exploit ng design flaw—at lumabas na free.
Nahaharap sina James at Anton Peraire-Bueno sa wire fraud at money laundering charges matapos daw i-manipulate ang MEV-boost system ng Ethereum noong April 2023. According sa prosecutors, gumawa ang brothers ng bait transactions para linlangin ang MEV bots na bumili ng ₱1.49 billion ($25 million) worth ng illiquid crypto, tapos gumamit ng invalid signature para baguhin ang block at i-flip ang trade into sell order. Naiwan ang bots sa walang halagang tokens habang nag-pocket ang brothers ng ₱1.49 billion ($25 million) sa stablecoins.
Malakas na nag-push back si Assistant US Attorney Danielle Kudla during Friday hearing, saying na always about deception at misrepresentation on the blockchain ang case. Noted niya na may specifications ang MEV-boost designed to prevent validators from modifying blocks, at hindi sana nag-execute ang bot owners ng trades kung alam nila kung ano ang mangyayari.
Nag-argue ang defense na walang terms of service ang Ethereum at MEV-boost, making the conduct lawful under network rules na nag-allow ng MEV activity. Tinanong ni Judge Clarke kung ang slashing penalty—yung mechanism ng Ethereum for punishing misbehaving validators—operates ba like a rule. Sabi ni Looby hindi, calling it merely a disincentive.
Nag-warn ang crypto think tank Coin Center sa letter to the court na massively chill daw sa public participation in innovative systems ang pag-convict sa brothers. Nag-submit din ang DeFi Education Fund ng similar letter arguing for acquittal, calling the prosecution a radical attempt to impose novel code of conduct sa Ethereum validators. Hindi mag-schedule si Judge Clarke ng new trial until mag-rule sa motion to dismiss, with any potential retrial starting no earlier than November 2025.
