Ethereum Developer Detained in Turkey Over ‘Blockchain Misuse’ Allegations — What We Know So Far

An Ethereum developer known pseudonymously as “Fede’s Intern” says he has been detained in the Turkish city of Izmir over allegations that he helped people “misuse” the blockchain network. The claim, which he denies, has sparked calls for transparency and due process from the crypto community. In a series of X posts , Fede’s Intern said local authorities told his lawyer that he could face charges. “It’s obviously wrong, we are just infra builders,” he wrote, adding that he had been advised to limit what he shared publicly. He urged followers to contact associates who could speak on his behalf. 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. — Fede’s intern (@fede_intern) August 10, 2025 Ethereum Dev Cites International Ties in Defense Effort The developer described himself as a businessman with operating companies in more than a dozen industries, headquartered in Europe and working with governments. “If we are the baddies I don’t know what to say. Everything we do is in the open,” he said. He claimed to have reached out to senior contacts in more than 10 countries, including in Europe, the US, the UAE and Asia. Friends from multiple jurisdictions were also calling officials in Turkey, he said, adding that there was a possibility he could leave the country and contest the allegations from abroad. Later, he said Turkey’s internal affairs minister had accused him of helping people misuse Ethereum. He reiterated his willingness to cooperate with Turkish authorities or any other government, while maintaining that neither he nor his companies had aided criminal activity. He indicated that a team of lawyers was already working on the case and that he might soon be able to fly to Europe on a private jet. Skepticism Delayed Public Disclosure of Detention His posts also described some unusual incidents during his detention. For example, he recounted experiencing an earthquake while in custody. He also witnessed an altercation involving an intoxicated British national in the same holding room. Fede’s Intern said he had delayed posting earlier because he anticipated skepticism. Moreover, he wanted to wait until his lawyer cleared him to speak publicly. He added, “I don’t know what the heck I win by inventing that this happened to me.” The developer’s detention has drawn comparisons to the case of Binance executive Tigran Gambaryan . He was arrested in Nigeria earlier this year alongside Nadeem Anjarwalla. As a result, both incidents have fueled debate over whether governments are overreaching in their enforcement actions against blockchain infrastructure providers. Definition of Ethereum “Misuse” Yet to Be Clarified Some in the crypto community believe translation errors could be to blame. Others think the issue stems from misunderstandings about Ethereum’s infrastructure. Meanwhile, some fear it points to a more aggressive regulatory stance in the region. Key questions remain unanswered. For instance, it is unclear whether the charges target Fede’s Intern personally or an affiliated company. In addition, it is not known if the detention is tied to a broader sweep of arrests announced by Turkey’s interior ministry earlier this week. Finally, questions remain over what specific activities are being labeled as “misuse” of Ethereum.. The developer promised to share more details once he leaves Turkey. He also said he would speak further after receiving legal clearance. In the meantime, the case has become a flashpoint in the ongoing tension between blockchain builders and regulatory authorities worldwide.
