Jonathan Spalletta Convicted for $53M Uranium Finance Hack

The verdict highlights that U.S. prosecutors and blockchain forensics can trace and seize large stolen crypto sums years after DeFi exploits.

Overview

  • A Manhattan jury found 36-year-old Jonathan Spalletta guilty of computer fraud and money laundering on Wednesday after a six-day trial in New York.
  • Prosecutors said two attacks in April 2021 drained Uranium Finance of about $53.3 million by abusing a rewards-tracking function on April 8 and a withdrawal-calculation error across liquidity pools on April 28.
  • Investigators seized roughly $31 million in cryptocurrency and more than $3 million in rare collectibles that Spalletta bought with illicit funds, with the main seizure occurring in February 2025.
  • Authorities say Spalletta laundered a large share of the theft through the Tornado Cash mixer—about $26 million by prosecutors' account—and then converted some proceeds into high‑value items like a Black Lotus card and first‑edition Pokémon sets.
  • Sentencing is set for Feb. 16, 2027, and the case underscores two hard truths for DeFi users: small smart‑contract logic errors can destroy pooled liquidity, and criminal tracing can recover assets but cannot by itself make victims whole.
