US Opposes DeFi Education Fund Brief Ahead of Possible MEV Case Retrial

US Court Rejects DeFi Education Fund’s Amicus Brief in High-Profile Ethereum Exploit Case

The US government has officially opposed efforts by the DeFi Education Fund (DEF) to submit an amicus brief in a controversial case involving allegations against two hackers accused of exploiting the Ethereum blockchain, resulting in a $25 million theft. The case has gained significant attention within the crypto community, raising questions about the legal boundaries of DeFi activities and automated trading bots.

Key Takeaways

• The US government filed a letter in court opposing DEF’s amicus brief, claiming it offers no new insights.
• The defendant brothers, Anton and James Peraire-Bueno, faced a mistrial in November after jurors failed to reach a verdict.
• The government has requested a retrial, scheduled for late February or early March 2026.
• Defense and advocacy groups argue the case could set a dangerous precedent impacting DeFi innovation.

Market context: The case exemplifies the ongoing legal challenges faced by the DeFi and crypto industries amid increased regulatory scrutiny.

Legal Proceedings and Industry Impact

The case centers on allegations that the Peraire-Bueno brothers used automated maximal extractable value (MEV) bots to orchestrate the exploit. In November, Judge Jessica Clarke declared a mistrial after jurors could not reach a verdict on whether to convict or acquit the defendants, who face charges including conspiracy to commit wire fraud, money laundering, and conspiracy to receive stolen property. If convicted upon retrial, they could face a combined sentence of up to 60 years in prison.

Advocacy groups like Coin Center had previously filed amicus briefs supporting the defendants’ right to a fair trial, though prosecutors opposed such submissions. The DEF’s draft brief argues that the case could have broader implications for DeFi development, citing fears that aggressive prosecution may chill participation and innovation within the ecosystem. DEF warns that overreach in such legal actions could sow confusion and hinder growth by creating uncertainty around regulatory expectations.

While the legal process unfolds, industry commentators continue to debate how this case may influence future regulatory approaches to automated trading strategies and blockchain exploits. As the trial progresses, it highlights the delicate balance regulators must strike between enforcement and fostering innovation in decentralized finance.
