A U.S. indictment alleges that Jonathan Spalletta exploited Uranium Finance, a decentralized cryptocurrency exchange, twice in April 2021 and moved the proceeds through multiple wallets and blockchains, including Tornado Cash (a crypto transaction-mixing protocol). Prosecutors say the attacks extracted approximately $1.4 million and $53.3 million, forcing the exchange to shut down, while the charges involve more than $50 million overall. The alleged proceeds were used to buy high-value collectibles, including Magic: The Gathering and Pokémon cards, as well as historical items. Spalletta surrendered after the indictment was unsealed on March 30, 2026, and was due to appear before U.S. Magistrate Judge Ona T. Wang. Separately, authorities seized approximately $31 million in cryptocurrency on February 24, 2025. The case illustrates how investigators combine blockchain transaction records with purchase records and seized property, while the indictment remains an allegation rather than a court finding of guilt.
