One of Russia’s largest cryptocurrency exchanges, Grinex, abruptly ceased operations on April 16, 2025, following a cyberattack that resulted in the theft of over 1 billion rubles ($13 million).

The announcement was made via Grinex’s Telegram channel, where operators cited the attack as the cause for the shutdown. The post alleged that the attack displayed “signs of involvement by foreign intelligence services” due to the “unprecedented level of resources and technology available exclusively to agencies of hostile states.”

The collapse of Grinex marks a significant setback for Russia’s sanctions-dodging financial infrastructure, particularly as the exchange facilitated nearly $100 billion in A7A5 stablecoin transactions in 2025.

“Grinex going dark presents serious damage to that infrastructure, not just because of the hack itself, but because it removes the exchange Russian businesses relied on to convert rubles into usable international currency.”

What is Grinex?

Grinex is the successor to Garantex, a previously sanctioned and shuttered crypto exchange. Both platforms were established to provide a financial lifeline for the Russian economy, which has faced severe pressure from international sanctions imposed after President Vladimir Putin’s regime invaded Ukraine in 2022.

Grinex played a pivotal role in facilitating transactions using A7A5, a sanctioned stablecoin that allowed sanctioned firms to conduct business outside the global banking network.

In August 2025, the U.S., European Union, and United Kingdom sanctioned Grinex, along with Old Vector, the company behind A7A5. Western authorities described the exchange and stablecoin as components of a “shadow financial system” designed to bypass international sanctions.

Russia’s Economic Struggles Deepen

Economic experts warn that U.S.-led sanctions have significantly weakened Russia’s economy. Recent data revealed a 1.8% decline in GDP during January and February 2025, falling short of Kremlin expectations.

Russia’s seaborne oil exports, a critical revenue source, are projected to drop to their lowest levels since 2023 due to infrastructure damage, likely a result of the ongoing war.

Some European leaders, including Thomas Nilsson, head of Sweden’s military intelligence and security service, suggest the economic decline may be even steeper than reported.

“The Russian economy can only enter one of two scenarios: long-term decline or shock. Either way, they will continue on a downslope to a financial disaster.”
