Israel extradites Alexander Block to US over alleged $2.8m Nomad crypto bridge hack

Key points

• Alexander Block was handed over to US authorities early on 29 Oct after the Supreme Court dismissed his final challenges.
• He faces eight federal counts in California, including computer offences, transferring stolen property and money laundering, from an August 2023 indictment.
• The court ruled that exploiting a code flaw can count as unlawful intrusion, and that public blockchains do not rule out laundering.

Israel has extradited Alexander Block, an Israeli-Russian citizen accused over the $2.8m Nomad crypto bridge hack, to the United States after the country's Supreme Court rejected his final appeals, Bitcoin.com News reports.

The Jerusalem District Court approved the handover in July 2025. Block then argued that the transactions used functions built into Nomad's system and so were not unlawful intrusion under Israeli law, and that the visibility of blockchain records undercut the laundering claims. The Supreme Court disagreed on both points, finding that exploiting a programming vulnerability can amount to intrusion and that transparent transfers do not prevent concealment, since wallet ownership is not always clear.

Israeli authorities coordinated the transfer early on 29 Oct through the State Attorney's Office international department, the Israel Police's operational coordination division and Interpol units, the office said.

What to watch: Block now faces the eight federal counts in the Northern District of California, where the case proceeds.
