The Garantex Crypto Laundering Network

How a sanctioned Russian crypto exchange allegedly reconstituted itself through a successor platform and a ruble-backed token after a 2025 law-enforcement disruption — and how an analyst can trace the structure from open sources.

A network that outlived its own seizure

Crypto exchanges are durable infrastructure for sanctions evasion precisely because the people and code can migrate faster than enforcement. The reporting around Garantex is a clean case study in that durability: an exchange disrupted by law enforcement that allegedly carried its customers, balances, and operators into a successor platform within weeks.

This brief synthesises public reporting from blockchain-analytics firms and investigative outlets. Every entity, figure, and date below is reported, not independently confirmed by us — primary designation records (OFAC) were not reachable from our research environment, and per our forensic rule a blocked fetch is not verification. Use this as a sourced starting map, not a settled record.

As of date: figures and structure here reflect reporting through mid-2026 and decay quickly. Re-confirm any specific entity against the live designation list before relying on it.

How to trace a successor-exchange pattern

The Garantex-to-successor shape recurs. The method below is reusable on any exchange that claims to have “closed” under pressure.

SignalWhere to lookWhat it tells you
Balance migrationOn-chain flows from the old hot walletsWhether funds moved to a new cluster after the disruption
Shared operatorsDesignation lists, corporate registries (incl. Kyrgyz Republic)Personnel overlap between the two platforms
New incorporation timingCompany registry of the successor's jurisdictionWhether the successor predates the seizure (pre-positioning)
Bridging tokenToken contract + issuer registrationThe instrument used to make frozen users whole
Marketing continuityPublic promotional material, mirror domainsExplicit framing as a successor

Method note: on-chain flows can be confirmed independently with blockchain analytics; corporate and personnel links usually cannot be confirmed from open sources alone and should stay tagged reported until a primary record is checked.

Common questions

Is Grinex the same company as Garantex?

Reporting describes Grinex as a successor that received Garantex customer balances and is framed as a response to the action against Garantex. Whether it is legally the same entity is a separate question; we record the relationship as reported, not as a confirmed identity.

What is the A7A5 token's role?

It is reported as a ruble-backed token used to let affected users recover balances after the disruption, attributed to a Kyrgyzstani issuer. As with every figure here, treat that as sourced reporting pending primary confirmation.

How can I verify these claims myself?

Cross-check the designation against the issuing authority's own list, confirm on-chain balance migration with a blockchain-analytics tool, and pull the successor's incorporation record from its jurisdiction's registry. A blocked or failed fetch is never treated as confirmation.
