UK zeroes in on crypto cashflows
On Thursday, the UK government imposed sanctions on three cryptocurrency exchanges and two payment processors, targeting a total of 38 new entities and individuals in its latest effort to curb Russian
The sanctions package also targets Processing KG, which operates VexPay and is linked to Kyrgyzstan’s Ministry of Finance, as well as Tsunami Payments. Ulan Bukabaev, Processing KG’s director, was individually designated. With these moves, the UK expands its list of sanctioned crypto firms after a similar action in May that included Huobi Global and HTX for allegedly helping Russia evade Western restrictions.
Kremlin-backed stablecoin in the spotlight
At the heart of the UK’s action is A7—a Kremlin-backed financial network that operates the ruble-pegged stablecoin A7A5. British authorities allege that two of the newly sanctioned companies facilitated transactions with A7, which last year claimed to have moved over $90 billion through its network.
A7’s $90 billion figure for 2023 was cited in a UK government statement released on June 13.
The scale of these flows stands out against broader efforts to isolate Russia financially since its invasion of Ukraine. While A7’s headline figure is enormous, it remains uncertain how much of this activity directly involved sanctioned Russian entities or was routed through illicit channels.
A7’s claim of $90 billion moved in 2023 dwarfs most other stablecoin operations tied to state actors.
Chainalysis reveals illicit transaction surge
Chainalysis data underscores why UK authorities are concerned: Cryptomus and Heleket reportedly received funds from thousands of illicit counterparties, peaking at 900 such entities in a single month during late 2025. The analytics firm also found that TokenSpot, Grinex, and Meer collectively received over $308 million from a single HTX deposit address, suggesting deep interconnections within this ecosystem.
This web extends beyond just exchanges. Payment platforms like Processing KG (VexPay) and Tsunami Payments—both sanctioned—were also implicated for facilitating flows with A7. According to coindesk.com, British officials believe these platforms played a role in helping Russian actors sidestep restrictions imposed since 2022.

Kyrgyzstan platforms under Western scrutiny
Three of the newly sanctioned service providers are linked to Kyrgyzstan: TokenSpot, Tsunami Payments, and Processing KG all operate out of Bishkek or maintain close ties to local authorities. Notably, TokenSpot and Tsunami Payments share an office tower in the Kyrgyz capital—a detail that highlights how regional hubs can serve as conduits for cross-border crypto flows despite international pressure.
Yet there’s a tension here: while some targeted firms are registered far from Moscow (such as Xeltox Enterprises in Canada), their operational links to Russia remain central to UK concerns about sanction evasion. This geographic spread complicates enforcement but demonstrates how networks adapt under scrutiny.
Why it matters
For everyday users and businesses interacting with crypto services abroad, these sanctions mean immediate restrictions: assets frozen within the UK, blocked payments through British banks, and even internet service bans requiring social media platforms and app stores to restrict access by UK users. In practical terms, anyone transacting with Cryptomus, Heleket, TokenSpot, or associated payment services now risks legal exposure if based in Britain or dealing with British partners.
The broader crackdown signals London’s intent to close loopholes exploited by Russian-linked actors using digital assets. With more than 600 tankers and dozens of oil companies now on the UK sanctions list—including Zarubezhneft and INK Capital—the government is pushing for tighter controls across both traditional energy markets and emerging digital finance channels.
Developments to follow
If British financial institutions are observed freezing assets or blocking payments to Cryptomus, Heleket, Certa Payments, TokenSpot, Processing KG, or Tsunami Payments following the U.K. sanctions announced Thursday, it would immediately restrict these firms' access to the U.K. financial system; however, which specific entities processed transactions with the Kremlin-backed A7 network remains unclear as the government has not specified this detail.
