UK Cryptomus Sanctions Widen Pressure on Russia's A7 Network

The UK Cryptomus sanctions announced on Thursday, October 8, 2026, extend Britain's campaign against crypto rails it says Russia uses to sidestep financial restrictions. The Foreign, Commonwealth and Development Office named three cryptocurrency exchanges and two payment platforms in a package of 38 new designations, CoinDesk reported, saying two of the targets had processed or facilitated transactions involving A7, a Kremlin-backed network behind the ruble-pegged A7A5 stablecoin.

What happened

The government named Xeltox Enterprises, the Canadian-registered company behind the Cryptomus, Heleket and Certa Payments platforms, and Kyrgyzstan-based TokenSpot. It also sanctioned payment platforms Processing KG, which operates VexPay, and Tsunami Payments, along with Ulan Bukabaev, a director of Processing KG, CoinDesk said.

Decrypt added detail from the UK sanctions notice. Xeltox, registered in Vancouver, was designated through its ownership of Cryptomus and activities "linked to and continued via" Heleket. TokenSpot and Tsunami Payments share an office tower in Bishkek. Processing KG's parent company is Kyrgyzstan's Ministry of Finance, according to the notice, which makes the designation an unusual case of sanctions reaching a payment firm owned by a foreign government ministry. The government said two of the targets handled A7 transactions but did not specify which.

The designations freeze any assets the named entities hold in the United Kingdom, and British financial institutions are barred from processing payments to, from or through several of the firms, CoinDesk reported. Decrypt said four of the companies also face internet services sanctions, which require social media platforms, internet providers and app stores to take reasonable steps to stop UK users from reaching their sites and apps.

"The message is simple: if you help Russia fund or equip this war, you will face the consequences," the Foreign Office said in a post announcing the package.

Why it matters

The UK Cryptomus sanctions target infrastructure rather than individual traders. The UK describes A7 as an "illicit finance network" used to get around sanctions on Russia's financial sector, and says the network claimed to have moved more than $90 billion last year, roughly half of Russia's annual military spending, according to Decrypt. CoinDesk noted that blockchain-data firms have disputed how much A7A5 activity is actually taking place.

The action builds on earlier moves. Britain previously sanctioned exchanges Grinex and Garantex, which have been linked to the network behind A7A5, and the United States later targeted the companies and executives behind the token and those exchanges, CoinDesk said. In May, the UK sanctioned other crypto platforms, including HTX, accusing it of providing financial services to A7. The European Union's 21st package, deployed in July, targeted 14 crypto companies and included four designations related to A7. We covered the U.S. side in our report on Treasury's A7 network sanctions.

The crypto listings were only part of the package. It also covers Russian oil producers Zarubezhneft and INK Capital, which the government said brings UK sanctions to more than 90% of Russia's oil production capacity, according to Decrypt. Another 12 shadow-fleet tankers were added, taking the total sanctioned to more than 600, along with 17 entities and individuals supplying goods for Russia's missile and drone production.

The contrast with Russia's domestic policy is sharp. Moscow has been building a licensed onshore crypto market, as shown in our report on the Russia crypto exchange registry, even as Western governments squeeze the offshore channels that serve Russian flows.

What's next

The immediate effect of the UK Cryptomus sanctions falls on UK persons and firms, which must cut off dealings with the named entities. Exchanges and payment companies with British operations will need to screen for exposure to Cryptomus, Heleket, Certa Payments, TokenSpot, VexPay and Tsunami Payments, including indirect flows through intermediaries. The internet services restrictions mean the platforms' sites and apps should become harder to reach from Britain as providers comply.

Attention now turns to whether the United States and the EU mirror the designations, as they have with earlier A7-linked targets, and whether exchanges and stablecoin issuers act on addresses associated with the newly named platforms. Disputes over the real scale of A7A5 activity are also likely to continue, since the UK's figures come from the network's own claims.
