Russia targets 17-year-old Browder over A7A5 crypto findings

Russia has sanctioned 17-year-old British student Alexander Browder after his crypto research helped UK officials target a ruble-backed stablecoin network accused of moving funds for Moscow’s war economy.

TASS, Russia’s state news agency, reported Tuesday that Browder was one of five British citizens added to Moscow’s “stop list” after Russia accused them of spreading what its Foreign Ministry called false claims about the country.

Russia targets teen researcher after A7A5 probe

Browder, the son of Kremlin critic Sir Bill Browder, spent 18 months studying A7A5, a ruble-pegged stablecoin issued by Kyrgyzstan-based Old Vector and hosted on the Tron and Ethereum blockchains. According to his Global Cryptocurrency Laundering Database website, his work appeared in a Henry Jackson Society report titled “Confronting the Illicit-Finance Hydra in Crypto Markets,” which reviewed 164 crypto laundering cases across two decades.

The teenager also advised UK ministers before Britain announced fresh sanctions on entities tied to A7A5. In comments to Metro, Browder said the Russian sanctions did not intimidate him and argued that Moscow’s response showed his work had “touched a nerve.” On X, he described himself as the first high school student sanctioned by an authoritarian government for exposing corruption.

UK says A7A5 helped bypass Western sanctions

According to a May 26 UK Foreign Office statement, A7A5 formed part of a network built to bypass Western sanctions and processed more than $90 billion in transactions last year. Foreign Secretary Yvette Cooper said Britain was targeting the “infrastructure that underpins” Russia’s war economy.

Browder’s research estimated that rogue states, including Iran and North Korea, laundered about $350 billion in illegal funds, with roughly half allegedly moving through the A7A5 network. Elliptic, a blockchain analytics firm, reported in January that A7A5 handled more than $100 billion in transactions during its first year.

Western governments expand crypto sanctions

Britain’s May 26 designations targeted 18 entities linked to the alleged network. According to the UK government, the list included a Kyrgyz bank suspected of enabling payments and a crypto exchange accused of sending more than $1.5 billion to Moscow.

At the same time, European authorities have also moved against Russia-linked crypto services. In April, the European Union introduced its 20th sanctions package and banned Russia-based crypto service providers. The EU package, also named A7A5 and another ruble-backed stablecoin, RUBx.

Reuters reported last month that Kyrgyzstan shut down 50 companies over sanctions-evasion concerns. Kyrgyzstan’s Ministry of Justice said the firms posed “high sanctions risk,” but it did not publicly name them.

Moscow adds four other Britons to the stop list

Besides Browder, TASS identified the sanctioned British citizens as Washington Post journalist Catherine Belton, CTG managing director Alice Mary Laugher, Chelsea Group founder Richard Nicolas Westbury, and The i Paper journalist Richard Holmes.

Russia’s Foreign Ministry said the list would keep expanding in response to what it called unfriendly actions by British authorities. Browder told GB News that Moscow’s move could make people more afraid to work with A7A5, although he tied that outcome to how strongly governments enforce the sanctions.
