UK Sanctions Cryptomus and TokenSpot Over Russia's $110 Billion A7A5 Stablecoin Network

38 New Designations Target Crypto Payment Rails

Britain sanctioned three cryptocurrency exchanges and two payment platforms on Thursday, accusing them of helping Russian entities evade Western financial restrictions. The Foreign, Commonwealth and Development Office set out the measures in its announcement on 8 October, a 38-target package whose scope reaches well beyond crypto: Russian oil producers Zarubezhneft and INK Capital were designated alongside 12 more shadow fleet tankers, lifting the sanctioned tanker count past 600 and pushing UK measures above 90 percent of Russia’s oil production capacity. The package also adds 17 entities and individuals tied to supplying goods critical to Russia’s missile and drone production. The crypto designations land hardest on Cryptomus. Its Vancouver-registered owner, Xeltox Enterprises, was designated through its ownership of the platform and activities “linked to and continued via” Heleket, the UK’s official sanctions notice states. Kyrgyz firms TokenSpot and Tsunami Payments, which share an office tower in Bishkek, were named as well. Processing KG, operator of the VexPay payment service and a subsidiary of Kyrgyzstan’s Ministry of Finance, was designated together with its director, Ulan Bukabaev. Two of the five platforms processed or facilitated transactions for the A7 network, which the government describes as a Kremlin-backed illicit finance operation used to bypass restrictions on Russia’s financial sector. The network itself said it moved more than $90 billion in the past year, an amount close to half of Russia’s annual military budget. Beyond asset freezes, the four companies face internet services sanctions: the layer obliges app stores, internet providers and social networks to restrict what UK users can reach. The package follows months of escalation: Washington listed A7 as a transnational criminal organization, the EU is moving toward a blanket ban on crypto transactions with Russian entities, and a dedicated UK enforcement operation has produced 128 arrests alongside crypto and cash seizures.

Chainalysis Traces $308 Million to One HTX Wallet

On-chain analytics flesh out the government’s case. Chainalysis found that Cryptomus and Heleket, two of the newly designated processors, took in funds from thousands of illicit counterparties, with monthly inflows hitting a peak of 900 distinct entities late in 2025. The Foreign Ministry said cutting off such services makes it harder for sanctioned entities to move and access funds. Three of the designated providers were linked to Kyrgyzstan, giving the package a clear regional focus. The same analytics work tied TokenSpot, a Kyrgyz exchange offering spot trading services, along with platforms Grinex and Meer, to more than $308 million received from one shared HTX deposit wallet. HTX itself sits at the center of the wider designations story: UK authorities sanctioned Huobi Global, the exchange’s operator, in May, and HTX pushed back, arguing the measure applied only to Huobi Global as a separate legal entity while its online exchange and user funds remained unaffected. Kyrgyzstan had moved in the same month, ordering 50 domestic companies to cease activity after state agencies flagged them for sanctions risks. The ruble-backed A7A5 stablecoin shows why enforcement keeps expanding: cumulative on-chain transactions on the token reached $110 billion by June and kept growing despite successive Western designations, according to figures from security firm CertiK. Tracing work in this sector increasingly follows funds through crypto mixer services and nested payment processors before settlement, one reason the UK extended its list beyond exchanges to the rails that feed them.

Enforcement Moves Down the Payment Stack

The 8 October package shows UK enforcement moving deeper into the plumbing. Under the notice, UK persons must not deal with the designated firms or make funds available to them, and the internet services layer pulls in social platforms, providers and app stores to restrict access from Britain. Stacked on the May designation of Huobi Global and Washington’s criminal-organization listing of A7, it builds a layered wall around Russian payment channels. None of the sanctioned names competed with the venues that dominate retail roundups of the Best Crypto Exchanges; they worked as offshore processors nested behind mainstream flows. Yet the $110 billion in A7A5 throughput recorded by June indicates volume kept outrunning designations through the first half of the year, and Italy’s central bank has separately ordered sanctions screening on crypto transfers. Designations of this kind typically bite through banking and internet access before they bite through on-chain volume. Kyrgyzstan’s own cleanup, with 50 companies ordered offline in May, points to Central Asia becoming an active compliance front rather than a passive conduit.
