The United Kingdom has imposed sanctions on several cryptocurrency platforms and payment processors accused of facilitating transactions that help Russian entities bypass international financial restrictions. The measures, announced on October 8 as part of a broader package of 38 designations, focus on networks linked to sanctions evasion, oil revenues and military supply chains.

The Foreign, Commonwealth & Development Office named Xeltox Enterprises Ltd., a Canadian-registered company operating the crypto payment services Cryptomus and Heleket, along with Kyrgyzstan-based TokenSpot. Additional designations cover Processing KG, which operates VexPay, Tsunami Payments and Processing KG director Ulan Arymbaevich Bukabaev. Some listings also reference Planeta.

Links to Illicit Flows and the A7 Network

Authorities stated that two of the targeted platforms processed or facilitated transactions involving A7, a network described as Kremlin-backed. A7 has claimed to have moved more than $90 billion during 2025, a figure British officials noted is close to half of Russia’s annual military spending. The network relies on the ruble-backed stablecoin A7A5, previously designated by U.S. authorities.

Blockchain analysis firm Chainalysis reported that Cryptomus and Heleket handled payments from more than 15,000 distinct illicit counterparties. These flows were associated with scams, fraud operations, ransomware and organized criminal groups. The firm assessed that the platforms’ exposure to sanctioned jurisdictions, terrorist financing and other unlawful activity exceeded that of all tracked crypto mixing services combined. Activity surged in late 2025, with more than 900 linked entities identified in a single month following the closure of the previously sanctioned Russian exchange Garantex.

Cryptomus had already drawn regulatory attention in Canada, where the Financial Transactions and Reports Analysis Centre imposed a penalty of approximately $130 million in October 2025 for failures to meet anti-money laundering and counter-terrorist financing requirements.

TokenSpot Transfers and Connections to Sanctioned Exchanges

TokenSpot, headquartered in Kyrgyzstan, faces particular scrutiny over large-scale transfers. Analysis by TRM Labs linked the platform to more than $950 million sent to the sanctioned exchanges Grinex and Garantex as well as the A7 network. The firm assessed with high confidence that TokenSpot functions as a front for Grinex, citing shared wallet infrastructure.

Chainalysis separately found that TokenSpot, together with the Kyrgyz exchanges Grinex and Meer, directed funds to the same HTX deposit address that ultimately received over $308 million. These movements were connected to A7A5 activity. HTX, operated by Huobi Global, was itself designated by the UK in May.

Wider Sanctions Package Targets Oil and Military Supply Chains

The crypto designations form one element of a larger set of measures. British authorities also sanctioned Russian oil producers Zarubezhneft and INK Capital, stating that UK restrictions now cover more than 90 percent of Russia’s oil production capacity. Twelve additional tankers associated with the so-called shadow fleet were added, bringing the total number of sanctioned vessels above 600. A further 17 entities and individuals were designated for involvement in the supply of machine tools, electronics and materials used in ballistic missile and drone production.

Under the sanctions, assets held by designated parties in the United Kingdom are frozen. UK persons and financial institutions are prohibited from dealing with those funds or economic resources, including cryptoassets, subject to limited exemptions or licences. The restrictions apply to activity within UK territory and to UK nationals and companies wherever they operate.

The October package builds on earlier actions. In May the UK targeted several Russia-linked crypto and payment networks, including Huobi Global. The European Union’s 21st sanctions package in July extended transaction bans to 14 crypto-related platforms across multiple jurisdictions. U.S. authorities designated A7 as a transnational criminal organization on October 1 and proposed additional transfer restrictions through the Financial Crimes Enforcement Network.

The cumulative effect of these measures is intended to raise the cost and complexity of moving funds for sanctioned Russian networks while signalling that facilitation of evasion carries direct consequences for the platforms involved.
