Ethereum Dev Held in Turkey: Alleged Network ’Misuse’ Sparks Controversy

Turkish authorities detain key Ethereum developer—accusations swirl around protocol exploitation. Was it a crackdown or a misunderstanding?

The Arrest That Shook Crypto

An Ethereum core developer spent 12+ hours in custody after Turkish officials flagged 'suspicious transactions.' No formal charges—yet. The community fumes over vague allegations.

Decentralization Meets Border Control

Sources claim the detention stemmed from automated monitoring tools flagging irregular smart contract activity. Irony alert: a system designed to bypass governments got tangled in one.

Vitalik Weighs In

Ethereum's founder called for 'due process,' while crypto lawyers muttered about jurisdictional gray areas. Meanwhile, ETH dipped 2%—traders panic-selling before coffee, as usual.

Turkey's move highlights the growing friction between blockchain's borderless ethos and national regulators clutching their rulebooks. Next stop: extradition hearings or a quiet dismissal? Either way, the SEC is probably taking notes—between sips of their $27 artisanal latte.

Blockchain privacy tools are likely at the center of legal action

Although the developer did not give much information on the pending case, he disclosed that his team has faced several other incidents in recent years. He noted that when Tornado Cash co-founder Alexey Roman was detained, authorities called him to ask about Tutela.

Tutela is an academic paper and code that analyzed user privacy on Ethereum and Tornado Cash, and it has Carrone as one of the contributors. The paper showed that it is possible to deanonymize users, even though Carrone stated that his team did not do further work on this subject.

While it is unclear whether it is now the reason for his recent detention, the developer criticized the recent trend of governments targeting software companies working on privacy tools, noting that such actions do not make anyone a criminal.

He said:

“Writing code to make transactions private doesn’t make you a criminal. Criminals are those who break the law. WOULD anyone jail Linus Torvalds because someone built a missile that uses the Linux kernel?”

Interestingly, the developer does not appear to be bitter about the experience. Instead, he noted his love for the Turkish culture and added that he plans to deepen his formal engagement and relationships with government authorities and like-minded individuals.

Crypto community raises concerns about lawsuits targeting software developers

Meanwhile, the incident highlights the challenges facing blockchain developers, especially those working on privacy technology tools. Tornado Cash developer Roman Storm was recently convicted for operating an unlicensed money transmitter business.

While he was able to escape conviction for two other charges that carried more severe penalties, the criminal conviction against him means he could face up to five years in prison. Many people now believe this is a continuation of that trend.

Bankless founder Sean Adams described the Carrone incident as deeply troubling, especially because Istanbul is a proposed location for DevCon 2026.

Crypto Advocacy group Coin Center also highlighted concerns about authorities targeting developers. In a recent report on policy developments for the crypto industry,  the group noted that the Tornado Cash and the Samourai wallet cases were worrying signs, adding that privacy protocols and self-custody tools still face legal uncertainty and persecution.
