Elliptic ties A7A5's transfer collapse to Ukrainian drone strikes on Yandex data centers

The link between the drones and the stablecoin runs through one hosting fact, and Elliptic's Tom Robinson supplied it. He said A7A5's "primary use is to bridge rubles to Tether's USDT, primarily through the issuer's own exchange," and that the service "has been hosted by Yandex since Sep 2025" ^[5]. Before that it sat in Europe, and Robinson said sanctions in August 2025 "likely prompted a switch to Russian hosting" ^[6]. The token is also available on exchanges that rely on Yandex's services ^[2]. The stablecoin depends on Yandex, or rather its ruble-to-USDT exchange does.

We think that is the best-supported mechanism in the record and also its thinnest link. The record does not place the exchange in either of the data centers that were hit, and the company's own explanation moved from "scheduled work" to "technical problems" ^[7]. What Robinson has is timing: transactions collapsed immediately after the strikes ^[2].

A second reading is available, and Elliptic's own July report supports it. Average daily transaction volume had already fallen to $24.3 million in June, down 96% from the July 2025 peak, after coordinated U.S., U.K. and EU sanctions ^[12]. That implies a peak near $600 million a day ^[14]. Before the strikes, transfers ran at around 600 a day ^[16]; the latest 24-hour counts are 18 on Ethereum and 14 on Tron ^[15], 32 together ^[17], or 5.3% of the old rate ^[18] if the 600 covers both chains (the source does not say). Dollar volume and transfer counts are different measures, so the two declines do not stack. Still, sanctions took most of the dollar volume, and on the timing the drones took most of what was left.

The market cap has not followed. Aggregators put it at $455 million to $482 million ^[4], and at the low end a $1,500 day of trading is 0.00033% of it ^[13]. A market cap multiplies supply by a last trade price. With trades this rare, the figure reflects trades of at most about $1,500 a day and says little about what $455 million of tokens would fetch. Robinson said what remains is mainly swaps on decentralized exchanges such as Uniswap ^[3]. Uniswap removed A7A5 from its website in November 2025, though its smart contracts still support the token ^[3]. On Oct. 14 the company said it expected to resume operations "soon," and that promissory notes "can only be redeemed for rubles at the A7-Finance office" ^[8]. The support bot is down, and users have a phone number ^[10].

A7's other move is a payment product. Robinson said the USDT service it launched in October gives A7 "much-needed USDT, which could be used to provide liquidity for its struggling ruble-backed stablecoin, A7A5" ^[11]. Robinson framed that as a possibility. If A7A5 resumes and transfers climb back toward 600 a day, the hosting explanation holds. If services return and transfers stay near 32, sanctions and lost demand explain the collapse, and the data center strikes were an episode in a decline already under way.
