Ethereum Developer Reportedly Detained in Turkey — All We Know So Far

An Ethereum developer going by the pseudonym “Fede’s Intern” has reportedly been detained in Izmir, Turkey.

The incident, which unfolded over the weekend, sparked widespread concern, especially as details remain scarce and the accusations unclear.

Ethereum Dev Held in Turkey Over Mysterious ‘Misuse’ Claims

According to posts on X (formerly Twitter), Fede’s Intern stated that Turkish authorities claimed he had assisted people in misusing the Ethereum network.

“I’m in Turkey, Izmir. They are telling my lawyer that I helped people to misuse Ethereum, and I might have a charge,” the developer wrote.

Fede’s Intern, an Argentinian and renowned crypto researcher, denied any wrongdoing. He emphasized that he and his team are “just infra builders” and are open to cooperating with authorities.

In a follow-up statement, he revealed that Turkey’s Minister of Internal Affairs had specifically made the claim.

So we now have more information. The minister of internal affairs of Turkey is saying I helped people misuse @ethereum. I’m fully open to cooperate with any authorities from Turkey or any country, we didn’t help anybody do anything, but we will also defend ourselves.

The vague nature of the “misuse” allegation has raised questions within the crypto space. Cenk, a Turkish crypto commentator, noted that there is “zero legal basis” for a detention based solely on such claims.

This skepticism stems from Turkey applying existing commercial, consumer, and penal codes for crypto-related cases.

Amidst the supposed detention, Fede’s Intern posted intermittent updates, indicating he had been moved to a private room and served food.

He also claimed that arrangements were underway for him to leave Turkey via private jet to Europe within hours. Once in Europe, he would continue to fight the charges with a team of lawyers.

Messages from prominent figures in the Ethereum and Solana communities reportedly expressed support, with some offering legal connections.

Many call for transparency and due process, drawing precedent from Binance’s executive Tigran Gambaryan, who was arrested in Nigeria alongside Nadeem Anjarwalla.

However, some have expressed skepticism, suggesting the incident could involve translation errors or misunderstandings about the nature of blockchain infrastructure. Others worry it signals potential regulatory overreach in the region.

“Ethereum developer being held in Turkey – “Ethereum misuse” being given to him as the reason. Still developing. Very troubling. Wasn’t Istanbul a proposed location for DevCon 2026Ryan Sean Adams, a well-known Ethereum advocate, pointed out.

The unfolding situation has left several points unclear:

• Whether the charges are directed at Fede’s Intern personally or an affiliated entity.
• Is his detention connected in any way to a broader sweep of arrests announced by Turkey’s Ministry of Internal Affairs earlier this week?
• What specific actions are being classified as “misuse” of Ethereum?

Fede’s Intern has stated that he will share more concrete details once he is out of Turkey and his legal team approves.

For now, the situation remains fluid. The only certainty is that the intersection of blockchain technology, legal systems, and international jurisdictions can produce fast-moving, high-stakes scenarios.

This is especially true when the charges are as nebulous as “Ethereum misuse.”

This is a developing story. We will update as more information becomes available.
