Garantex
Web3 / exchanges trading
Garantex was a Moscow-based cryptocurrency exchange and one of the world's most prolific high-risk crypto platforms, operating as the primary financial infrastructure for Russia's illicit cryptocurrency ecosystem. It provided high-liquidity trading pairs, low fees, and near-absent KYC/AML enforcement, making it the preferred on/off-ramp for sanctioned Russian entities, ransomware gangs, darknet market operators, and money launderers. The exchange operated with apparent tacit tolerance from Russian authorities and processed billions of dollars in monthly volume — including funds linked to the Conti and Lazarus Group ransomware operations. OFAC sanctioned Garantex in April 2022, but the exchange continued operating at full volume until a coordinated multinational law-enforcement action by the US, Germany, and Finland seized $26 million and dismantled the platform in March 2025. Within days of the takedown, a successor exchange named Grinex appeared — registered in Kyrgyzstan just weeks earlier — preserving Garantex's operational team, technical infrastructure, and customer base. Grinex functioned as a near-seamless continuation of the laundering network under a new legal entity, with the A7A5 stablecoin serving as the bridge for customer balance transfers. In April 2026, Grinex suspended operations following a claimed $13.7 million cyberattack; blockchain forensics analysts widely suspect the incident was an orchestrated exit scam designed to siphon liquidity amid mounting pressure from the EU's 20th sanctions package and intensified international law-enforcement operations. The Garantex-to-Grinex succession directly drove the EU's strategic shift in the 20th sanctions package (April 2026) from entity-level targeting to a blanket sectorial prohibition on all CASPs registered in Russia or Belarus — recognition that whack-a-mole exchange designations are insufficient when the operational team simply reconstitutes under a new name. Why it matters for compliance: Garantex and its Grinex successor are the canonical case study in exchange-level sanctions evasion via jurisdictional arbitrage. Their history demonstrates that effective crypto sanctions require targeting the operational team, infrastructure fingerprints, and underlying stablecoin rails — not just the exchange entity name — and underpins the regulatory logic of the EU 20th package's blanket CASP prohibition.
