Israel has extradited Alexander Block to the United States to face charges tied to a 2022 Nomad Bridge exploit that prosecutors say involved $2.8 million in tokens.
The U.S. case alleges Block, previously known as Alexander Gurevich and a citizen of Israel and Russia, first sent six transfers to probe a weakness in Nomad’s smart contracts. Prosecutors say he followed with four larger transfers involving tokens worth $2.8 million.
Prosecutors also say Block routed the tokens through several wallets and exchanged them for other cryptocurrencies to obscure their origin. After the weakness surfaced, other users removed more than $186 million in digital assets from wallets under the project’s control.
Israel’s Supreme Court rejected Block’s challenge to extradition. The justices said that software accepting a transaction does not settle whether access was lawful when a defect was exploited. They also said blockchain activity alone may not identify the person behind a wallet or determine whether funds were deliberately concealed.
Chief Justice Isaac Amit later denied Block’s request for another hearing.
