An Ethereum developer known as “Fede’s Intern” was detained in Izmir, Turkey, after authorities accused him of assisting individuals in “misusing” the Ethereum network. On August 11, the Argentine crypto researcher posted on X that Turkish officials had informed his lawyer of the charges, which he called “obviously wrong.” He insisted that his work was strictly limited to building blockchain infrastructure and denied any participation in illegal activities.
What exactly are the accusations?
The charge against Fede centers on allegations that he helped individuals misuse the Ethereum network, though no formal documents or specific legal provisions have been made public, leaving the exact nature of the accusation unclear.
Fede later stated that Turkey’s Minister of Internal Affairs personally made the claim but did not provide further details on what authorities considered misuse.
He argued that “privacy is not a crime” and called on officials to focus on prosecuting actual criminals rather than targeting blockchain users or infrastructure developers.
Describing himself as a businessman with companies spanning more than a dozen industries under a European holding company, Fede emphasized that all his activities are transparent and conducted in cooperation with governments.
He also shared that he had reached out to influential contacts in over 10 countries, with friends across Europe, the U.S., the UAE, and Asia advocating on his behalf. According to Fede, these efforts seem to be having an effect, with signs he might be allowed to leave Turkey and contest the charges from abroad.
Later, Fede reported being moved to a private room, served food, and that plans were underway for him to depart Turkey on a private jet to Europe within hours.
Within hours, the case sparked widespread discussion within Ethereum and Solana communities, with industry leaders and members expressing serious concerns.
Ryan Sean Adams, a prominent Ethereum supporter, called the situation “very troubling” and pointed out the irony that Istanbul had been considered as a potential location for Devcon 2026.
Meanwhile, Turkish crypto commentator Cenk argued that there was “zero legal basis” for detaining someone solely based on such allegations.
Some observers have suggested the situation might stem from a translation error or a misunderstanding of blockchain infrastructure, while others cautioned that it could indicate broader regulatory overreach.
Fede stated he plans to share “more concrete information” once he returns to Europe and consults with his lawyers. He also expressed willingness to cooperate with Turkish authorities or officials from any other jurisdiction, while firmly asserting his intention to defend himself against the charges.
crypto.news reached out to Fede for comment but had not received a response by the time of publication.
As of press time, Fede had not confirmed his departure, and Turkish authorities had yet to issue any official statement regarding the detention or formal charges.
Turkey is intensifying its crackdown on cryptocurrency
Although details about Fede’s detention remain limited, it comes amid a broader push by Turkish regulators to tighten control over the digital asset sector. Since March, the country’s Capital Markets Board (CMB) has implemented a series of regulations that have significantly changed how crypto exchanges, custodians, and wallet providers operate.
The March framework introduced stringent licensing and operational requirements, obliging platforms to keep detailed transaction records, provide monthly account statements, and process orders exclusively through official channels.
In June, the Ministry of Treasury and Finance added further oversight measures focused on the flow of funds to and from crypto platforms. These included mandatory 20-character explanations for all transactions, withdrawal delays for transfers that don’t comply with travel rules, and strict daily and monthly limits on stablecoin transfers.
By July, the crackdown expanded into decentralized finance (DeFi). The CMB ordered Turkish internet service providers to block access to PancakeSwap, marking the first time a decentralized exchange was targeted in the country.
Regulators have also cautioned that other DeFi services, including non-custodial wallets, could face similar restrictions if they are found to be marketing directly to Turkish users.
