A September 2025 report detailed a marginfi flash-loan vulnerability that created a path to borrow without repaying, placing $160M at risk before a fix was applied. That same month, he published findings on a Relay Protocol signature-verification flaw that could have enabled forged allocator signatures and potential double-spends. In April 2026, he authored a report on a critical p-token bug caught before mainnet deployment.
