Avraham Eisenberg
Summary
Avraham Eisenberg, also known as 'Avi Eisenberg,' is a crypto trader who in October 2022 executed an oracle manipulation attack against Mango Markets, a Solana-based DeFi protocol, extracting approximately $110–117 million in digital assets. He publicly claimed the scheme was a 'highly profitable trading strategy' and a legal use of the protocol, returned approximately $67 million after a DAO-mediated settlement, and was subsequently charged by the DOJ, SEC, and CFTC. A federal jury convicted him in April 2024, but a federal judge vacated all criminal convictions in May 2025 on grounds of improper venue and insufficient evidence of material misrepresentation; prosecutors have appealed. Eisenberg is currently serving a separate 52-month federal prison sentence for possession of child sexual abuse material.
