Crypto Made Israel an Extradition Hub

By Sagiv Rotenberg, founding partner of Rotenberg Criminal Law Office in Tel Aviv. Rotenberg represents Israeli and international clients in extradition, Interpol, and cross-border crypto criminal matters, with more than 25 years of practice.

In recent years Israel has become, almost without serious public debate, one of the world’s most prominent centers for crypto-related extradition requests. This is a deep shift — legal, technological, and geopolitical — moving faster than Israel’s legal system and public are absorbing.

Until recently, international financial crime was conducted largely through banks, offshore companies, and accounts abroad. The arena has changed. Digital currencies do not recognize borders. Funds move between countries and continents in seconds, sometimes without a traditional financial intermediary, sometimes through routes that are nearly impossible to trace without advanced technological tools. Enforcement has changed in step. Blockchain was never anonymous — it is evidence.

Over the past few years, authorities in the United States, Germany, Brazil, Singapore, South Korea, and other countries have escalated their use of extradition proceedings, intelligence cooperation, and Interpol alerts against individuals linked to cross-border crypto activity. Sometimes these are clear fraud cases. Sometimes money laundering. Sometimes tax offenses. And sometimes the underlying question is far more complex — whether the conduct in question was criminal at all.

In many cases, the individual does not even know they are under investigation — until the moment of arrest.

A case in point: the Simon Leviev arrest

The pattern is not theoretical. In September 2025, Shimon Yehuda Hayut — publicly known as Simon Leviev, the subject of the Netflix documentary The Tinder Swindler — was detained in Georgia on the basis of a German extradition request routed through Interpol, tied to alleged fraud dating back to 2017–2019. I represented him in that proceeding, and spoke on the record about the matter to The New York Times. The mechanics of the arrest are the mechanics this article describes: a request filed in one European jurisdiction, an Interpol alert circulated internationally, a detention on arrival in a third country, and an Israeli citizen navigating parallel proceedings across multiple legal systems at once. The public tends to remember the Netflix framing. The legal reality — how quickly an Interpol notice becomes a physical arrest on the other side of the world — is the story that matters for anyone operating internationally.

Israel as a new international junction

Israel has become home to a significant share of the global blockchain industry. Local entrepreneurs have founded Web3 companies, DeFi platforms, NFT projects, crypto exchanges, security firms, and financial startups. Alongside that innovation, a new legal exposure has emerged.

When the investor sits in London, the company is registered in the Cayman Islands, the servers are in Europe, the wallet is connected to a decentralized protocol, and the founder is in Tel Aviv — the question of criminal jurisdiction is no longer self-evident.

And yet, many countries proceed as if it were. The result is a rise in requests reaching Israel concerning cross-border crypto investigations — alongside arrests, forfeiture requests, asset freezes, digital wallet seizures, and full extradition proceedings.

Interpol has become the most effective enforcement tool

One of the most significant shifts in the field is the role of Interpol.

Interpol was once perceived by many as an international information database. In practice, it has become a central part of the enforcement apparatus in crypto cases.

Red Notices, international locate requests, and rapid cross-country distributions have become standard working tools. Sometimes, even before a public indictment is filed or an open legal proceeding is initiated, there is already international movement between enforcement authorities concerning a particular person, a particular wallet address, or a specific financial activity.

In a world where a person can take off from Israel and discover upon landing that they are being detained at the border because of a request filed months earlier — the meaning of an Israeli passport has changed completely. If assets get frozen in parallel, see the legal appeal guide for frozen crypto wallets.

Technology runs faster than the law

The heart of the problem is not only enforcement — it is professional.

The modern crypto case almost always rests on blockchain analysis, wallet mapping, transaction tracing, address identification, and the linkage between digital assets and human identities. These can appear to be unambiguous evidence. In practice, they rest on a long chain of technological assumptions, probabilistic models, clustering, exchange-supplied information, and intelligence tools. For an ordinary wallet holder, that chain of inference is where good faith stops being a defense.

Courts in Israel are still in relatively early stages of grappling with these questions.

How does one prove ownership of a wallet?
How does one distinguish between a single user and multiple users?
How is the use of privacy tools interpreted?
What evidentiary weight does chain analysis carry?
When does it constitute conclusive evidence — and when only a technological hypothesis?

These are no longer niche questions. They are rapidly becoming core questions in international criminal law.

What needs to change

The Israeli system is not yet sufficiently prepared for this era.

International crypto cases are no longer ordinary white-collar cases. They combine technology, financial regulation, cross-border jurisdiction, digital evidence, international intelligence, and parallel criminal proceedings in multiple jurisdictions.

Deeper specialization is required across the whole system:
The investigators.
The prosecution.
The courts.
And the defense bar.

Courts handling such cases will have to engage with technological and economic questions far more complex than in the past. State authorities will need to formulate clearer policy on crypto extradition requests. And the public — and especially those operating in this world — needs to understand that the distance between global digital activity and an international criminal proceeding has narrowed considerably.

Looking forward

The crypto revolution will not stop. Nor will the enforcement infrastructure being built around it.

As the global financial system continues to move digital, so too do enforcement authorities, intelligence agencies, and extradition mechanisms — sometimes even faster.

Israel is at the heart of this revolution: both as a center of technological innovation and as a growing meeting point of entrepreneurship, regulation, and international enforcement.

The question is not whether more cross-border crypto cases will reach Israel.

The question is whether the system will be ready for them in time.
