Grinex and the Afterlife of Garantex: A Troubling Trend in Crypto Resilience
The world of cryptocurrency has long danced on the edge of innovation and controversy, but few stories illustrate this dance better than the sudden emergence of a new exchange called Grinex. At first glance, it might appear to be just another platform entering the already saturated crypto market. However, an in-depth investigation by TRM Labs—a leading blockchain intelligence firm—suggests otherwise.
Grinex may be far more than a simple new player. According to TRM Labs, the platform shares deep operational and structural ties with Garantex, a Russian crypto exchange that was previously sanctioned by U.S., U.K., and EU authorities for laundering billions in illicit funds, often on behalf of ransomware groups and darknet marketplaces. Garantex was shut down in March 2025, its domains seized and key figures arrested.
But Grinex has emerged like a phoenix from Garantex’s ashes. Promoted via Telegram by known affiliates of the defunct exchange, Grinex appears to be leveraging the same infrastructure, staff, and even customer base—complete with a new ruble-backed token named A7A5. While the surface is polished with branding and legitimacy, the skeleton of Garantex seems to lurk just beneath the surface.
Grinex: What We Know So Far
- TRM Labs, a prominent blockchain forensics firm, reported strong ties between Grinex and Garantex, though it stopped short of confirming ongoing illicit activity.
- Garantex, sanctioned by the U.S. Treasury’s OFAC in April 2022, was dismantled in March 2025 following allegations of facilitating over $100 billion in illegal transactions.
- Investigations linked Garantex to Conti ransomware, Hydra, Solaris, and other major darknet markets.
- Two administrators of Garantex were charged, with Aleksej Besciokov arrested in India.
- Just weeks after Garantex’s takedown, Grinex surfaced on Telegram, promoted by the Satoshkin group—previously aligned with Garantex.
- Grinex mirrored Garantex’s user interface and core functionality, suggesting a planned transition rather than a coincidence.
- Grinex claimed to onboard Garantex clients and hire its former employees, formalizing the continuity.
- The A7A5 token, a ruble-pegged stablecoin, emerged just prior to the Garantex crackdown and is now used to redistribute funds to former users.
- Two Kyrgyz firms are tied to large A7A5 transactions, but details remain murky.
- Telegram chatter among former Garantex circles now centers around Grinex as a solution to unlock frozen assets.
- Two more Garantex-aligned platforms have appeared: ABCEX, linked to founder Sergey Mendeleev, and Rapira, which has welcomed ex-Garantex clients.
- The story of Grinex exposes the limits of sanctions in a digital economy where platforms can rebrand and reboot overnight.
- TRM Labs emphasizes the challenge of enforcement as illicit actors exploit decentralized platforms, anonymity tools, and legal grey zones.
What Undercode Say:
The case of Grinex is not just a cautionary tale about crypto crime—it’s a glaring example of how agile and resilient cybercriminal infrastructures have become in the decentralized world.
Let’s be clear: this is not merely a resurrection. It’s a strategic reincarnation, likely orchestrated well before the final hammer fell on Garantex. The near-seamless transition in branding, staff acquisition, user onboarding, and asset redistribution speaks volumes about the foresight and coordination among the network’s architects.
The introduction of the A7A5 stablecoin just before the seizure wasn’t a fluke. It was a preemptive hedge, likely designed to enable fund mobility even after official clampdowns. And the use of a ruble-pegged stablecoin further indicates the geopolitical undertones—suggesting strong local demand and national currency hedging strategies to maintain user confidence.
The situation also exposes vulnerabilities in global sanction frameworks. Traditional law enforcement tactics—seizures, arrests, and blacklisting—are reactive by nature. Meanwhile, illicit actors have learned to be proactive. They build redundancies, prepare digital escapes, and exploit the transnational fluidity of blockchain tech to stay ahead of regulators.
Moreover, Telegram remains a crucial but largely unregulated communications channel, amplifying the reach of these new entities without consequence. The Garantex-to-Grinex pipeline was enabled, promoted, and normalized across these networks with shocking efficiency.
What’s perhaps most worrying is that Grinex isn’t alone. The emergence of ABCEX and Rapira highlights a pattern: when one platform falls, several sprout in its place—often carrying the same DNA. This suggests an ecosystem of collusion, where new platforms act as contingency nodes, offering familiar services under new banners.
The role of Kyrgyzstan-based firms also adds another layer. While direct culpability isn’t confirmed, the geographic spread of such operations muddies the waters of jurisdiction and oversight. It’s a stark reminder of the difficulty in tracing money once it moves beyond friendly regulatory borders.
Ultimately, what Grinex represents is more than a platform—it’s a model of criminal adaptability. One that mixes technical sophistication with strategic foresight, exploiting every loophole the global financial system has yet to close. And as long as users continue seeking ways to recover funds or bypass restrictions, these shadow platforms will continue to thrive in the gray.
Fact Checker Results:
- TRM Labs has not confirmed Grinex is currently engaging in criminal activity, only that it shares DNA with a sanctioned entity.
– A7A5
- Promotion of Grinex through Telegram by previously linked entities strongly supports the claim of organizational continuity.
