Uniswap May Be Blocking Its DApp in Ukraine Over OFAC Sanctions, Ukrainian User Says

• Uniswap’s dapp is currently inaccessible to users in parts of Ukraine.

• The platform reportedly cited the U.S. Department of the Treasury (OFAC) sanctions as justification.

• Support ticket 169045 and an open letter by a Ukrainian user seek prompt reinstatement of access; Uniswap has not publicly responded.

Uniswap blocked in Ukraine: Uniswap’s dapp remains inaccessible to Ukrainian users despite OFAC limits to Crimea and occupied regions — learn the facts and next steps.

The user said he had previously contacted Uniswap about this but the issue remains unresolved.

What is Uniswap blocked in Ukraine?

Uniswap blocked in Ukraine describes the current restriction preventing some Ukrainian users from accessing the Uniswap decentralized application (dapp). The block, referenced in a public appeal and support ticket 169045, is reported to be based on a precautionary interpretation of U.S. Treasury (OFAC) sanctions.

Why is Uniswap blocking access and what does OFAC actually sanction?

Uniswap’s team reportedly cited the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) as the reason for restricting access. OFAC sanctions, as publicly documented by the U.S. Department of the Treasury, specifically target Crimea and the Russia-occupied portions of Donetsk and Luhansk. These sanctioned designations do not list Kyiv or the broader territory of sovereign Ukraine outside those occupied regions.

Timeline and user account

On October 13, 2025, a Ukrainian user, Artem Chystiakov (social handle Arvolear), published an open letter on X (formerly Twitter) asking Uniswap to restore dapp access in Ukraine. The author says they previously filed support ticket 169045 but saw no change. The message emphasizes that Kyiv and other Ukrainian cities are not subject to the OFAC measures cited as justification.

“Kyiv and other Ukrainian cities are not mentioned whatsoever,” the user wrote, calling the restriction “absurd.” The post stresses that blocking users in wartime undermines DeFi’s promise of open access and trustless technology. The user added: “Crypto and DeFi as we know them today would not exist without Uniswap’s leadership and open-mindedness.”

Legal and compliance context

Platforms operating globally often apply conservative geo-compliance rules to avoid exposure to sanctioned jurisdictions. Publicly available OFAC guidance and sanctions lists identify specific geographic and legal designations. In this case, the sanctioned areas are Crimea and the Russia-occupied parts of Donetsk and Luhansk, according to U.S. Department of the Treasury materials. Legal analysts and compliance officers typically advise platforms to follow official sanction listings closely, but the case illustrates how overbroad enforcement can inadvertently block lawful users.

Frequently Asked Questions

Is Uniswap legally required to block all of Ukraine?

No. OFAC sanctions are geographically specific; publicly available OFAC documentation lists Crimea and specified occupied regions as sanctioned. Blocking the entire territory of Ukraine is not directly mandated by those designations, although platforms may take broader measures for risk-avoidance.

How can a blocked Ukrainian user regain access to Uniswap?

Users should document the issue and pursue formal support channels (for example, support ticket 169045 cited in the appeal), seek clarification from the platform, and raise the matter through public communication channels. Legal counsel or compliance specialists can also advise on remedial steps where access is necessary and lawful.

Reporting, sources and expert context

This report references the public appeal posted on X by Artem Chystiakov and official U.S. Department of the Treasury (OFAC) sanction designations as authoritative sources of fact. No external links are provided in accordance with publication policy. For context, platform compliance teams often consult the U.S. Department of the Treasury and legal counsel when implementing access restrictions.

Key Takeaways

• Scope mismatch: OFAC sanctions target Crimea and certain occupied regions, not the whole of Ukraine.
• User impact: Ukrainian users report blocked access to Uniswap’s dapp despite not being in sanctioned areas.
• Next steps: The affected user has filed support ticket 169045 and issued a public appeal; further clarification from Uniswap is awaited.

Conclusion

Uniswap blocked in Ukraine raises clear questions about how compliance measures are implemented by decentralized finance platforms. The public appeal from Artem Chystiakov and the unresolved support ticket 169045 highlight a possible overreach in enforcement relative to OFAC’s documented scope. COINOTAG will continue to monitor responses from Uniswap and official guidance from the U.S. Department of the Treasury, and will report updates as they are available.
