Ukrainian drone strikes on Yandex data centers have disrupted the operations of A7A5, a Russian ruble-pegged stablecoin built to evade Western sanctions, according to blockchain analytics firm Elliptic.

On the night of Oct. 7–8, Ukrainian drones struck a Yandex data center — Yandex is often described as "Russia's Google" — in Sasovo, sending shock waves across Russia. A second Yandex data center was hit during the same week. One consequence landed on A7A5, a ruble-pegged stablecoin operating on Ethereum and Tron that was designed to circumvent Western sanctions.

On-Chain Activity Collapses

Tom Robinson, chief scientist and co-founder of Elliptic, found that A7A5 transactions collapsed immediately after the Ukrainian strikes. The stablecoin is available on exchanges that rely on Yandex's services, and a graph shared by Robinson shows transaction activity plummeting right after the attacks.

At the time of writing, Etherscan shows roughly 17,600 A7A5 holders on Ethereum, with just 18 transfers in the previous 24 hours. Tron hosts more than 30,700 holders and recorded 14 A7A5 transfers over the same period. Before the drone strikes — which some commentators have dubbed "kinetic sanctions" — the token averaged around 600 transfers per day.

According to Robinson, the remaining transactions mainly involve the stablecoin being swapped on decentralized exchanges such as Uniswap. The platform removed A7A5 from its website in November 2025, but its underlying smart contracts continue to support the token.

Market data aggregators such as Coingecko and Coinmarketcap also show that the token's trading volume now ranges from zero to around $1,500 per day, despite a market capitalization of approximately $455 million to $482 million — a disparity that underscores how little liquid trading activity remains in the token.

"A7A5's primary use is to bridge rubles to Tether's $USDT, primarily through the issuer's own exchange. That service has been hosted by Yandex since Sep 2025. Before that it was hosted in Europe — but sanctions against A7A5 in Aug 2025 likely prompted a switch to Russian hosting," Robinson explained.

That reliance on a single Russian hosting provider turned physical infrastructure into a chokepoint for the token: with its main ruble-to-USDT bridge offline, one of the few documented rails for converting rubles into dollar-pegged stablecoins has been reduced to thin decentralized-exchange swaps.

From 'Scheduled Work' to 'Technical Problems'

On Oct. 8, official A7A5 Telegram channels announced that some services might be unavailable because of "scheduled" and "temporary technical work." The next day, the explanation changed from "scheduled work" to "technical problems." On Oct. 14, A7A5 said it expected to resume operations "soon."

Users also asked how they could obtain promissory notes for orders they had already paid for. The company said the notes "can only be redeemed for rubles at the A7-Finance office."

Other users complained that they had not received interest on their holdings since Oct. 9. The company promised to pay the full amount of interest owed for all missed days.

The support bot is also down, leaving users with only a phone number to contact the company. "Well, the guys in the West earn their keep, since they knew where to strike…" one user said in an A7A5 Telegram chat.

The Ongoing Collapse

A7A5 is a ruble-pegged stablecoin issued in Kyrgyzstan and created by A7 LLC. The company claims the token is backed by deposits at sanctioned Russian state bank Promsvyazbank.

As Bitcoin.com News reported in June 2026, Stanislav Lazarev, A7's first deputy general director for sales, said that "Western compliance pressure" would push Russia toward independent digital payments.

Meanwhile, in October, following the strikes, A7 launched a new service that lets businesses pay in $USDT, while A7 sends the funds to their suppliers through ordinary SWIFT bank transfers. According to Robinson, this new service provides A7 "with much-needed $USDT, which could be used to provide liquidity for its struggling ruble-backed stablecoin, A7A5."

In July, Elliptic reported that average daily A7A5 transaction volumes had fallen to $24.3 million in June 2026, down 96% from the token's July 2025 peak, as the U.S., U.K., and EU had imposed coordinated sanctions on the token.

A7A5's own Oct. 14 pledge to resume operations "soon," together with the new USDT settlement service, now offers the clearest markers for gauging whether the token's transfer counts can climb back from their post-strike lows.
