UK sanctions $90B Russia-linked crypto networks

TLDR

The UK has sanctioned a Russia-linked crypto payment network accused of moving over $90 billion tied to the war in Ukraine.

1. The UK added 18 Russia-linked crypto platforms and banks to its sanctions list over their role in a Kremlin-backed payment network.
2. Blockchain analysis suggests this network processed over $90 billion in 2025 via a token and wallets used to route funds to sanctioned Russian entities.
3. The move raises compliance risk for exchanges and users, especially in the UK, and points to tougher global enforcement against sanctions evasion using crypto.

Deep Dive

1. What The UK Just Sanctioned

According to reporting on the UK action, authorities sanctioned 18 crypto platforms, banks, and financial networks connected to Russias A7 payment network, which is described as Kremlin-backed and used to fund the invasion of Ukraine.

The A7 network allegedly processed over $90 billion in 2025 via its A7A5 token and associated wallets, largely flowing through previously sanctioned venues like Garantex and newer exchanges such as Grinex. UK businesses must now freeze assets and block transactions involving the listed entities, which were added to the UK Consolidated List.

TRM Labs analysis cited in coverage names Huobi, Exmo, Bitpapa, Rapira Group and others as platforms that transacted heavily with A7 and sanctioned Russian entities, with Huobi alone routing billions of dollars in on-chain flows to those channels.

2. How It Affects Crypto Platforms And Users

For any UK person or firm, dealing with the sanctioned entities is now prohibited: banks, payment processors, and compliant exchanges must block transfers and freeze assets linked to them.

Even outside the UK, large centralized exchanges may de-risk by cutting off relationships with the named platforms to avoid secondary compliance exposure, which can reduce liquidity and access on smaller Russia-linked venues.

The case also highlights how forensic tools can link mainstream exchanges to illicit flows, as TRM Labs traced multi-billion-dollar paths from major exchanges to A7 and other sanctioned actors, raising the bar for know-your-customer and sanctions screening controls.

3. What To Watch Next

First, watch for follow-on actions: more wallet designations, asset freezes, or parallel moves by the US or EU targeting the same A7-linked infrastructure.

Second, monitor whether major exchanges publicly adjust their compliance posture or delist any related tokens, including the A7A5 token that sat at the center of the reported A7 payment network processing over $90 billion.

Finally, regulators may use this case to justify broader rules on travel rule compliance, VASP licensing, and mandatory blockchain analytics for exchanges, especially when serving users in or near sanctioned jurisdictions.

Conclusion

The UKs move against Russia-linked crypto networks shows that regulators now treat large-scale digital asset flows as core sanctions terrain, not an afterthought. For crypto users and platforms, the practical takeaway is tighter screening, more fragmented venue risk, and growing evidence that even very large, cross-border crypto payment networks can be traced and cut off when linked to state-sanctioned activity.
