Lead: The Public Interest
Official enforcement disclosures published by the United States Department of the Treasury delineate an intricate, multi-layered nexus of digital asset brokers, shell trading firms, and state-linked financial vectors operating across four continents. By mapping specific blockchain identifiers and corporate registration registries to designated actors, the public record exposes how modern illicit value transfer circumvents traditional banking barriers. Understanding these exact logistical and jurisdictional pathways is vital for international financial transparency and monitoring the evolution of global economic sanctions.
Historical and Geopolitical Context
Over the past decade, regulatory tightening around conventional banking corridors has forced regional entities subject to comprehensive sanctions to migrate value into decentralized digital ledgers and multi-jurisdictional corporate umbrellas. The geographic dispersion revealed in administrative filings highlights a deliberate structural adaptation: trading firms and financial service operations are systematically incorporated across trade hubs like Dubai, Hong Kong, Singapore, Warsaw, and Tbilisi to disperse operational risk.
This infrastructural architecture relies on dual-track operations. Physical corporate shells maintain local commercial trade licenses while back-end financial operations manage digital asset liquidity across major blockchain networks, including Bitcoin, Ethereum, Tron, Binance Chain, and Solana. Executive Orders such as E.O. 13902 and E.O. 13224—reinforced by amendatory directives like E.O. 13886—serve as the statutory architecture deployed to disrupt these secondary exchange mechanisms before they settle into permanent commercial corridors.
Simultaneously, the global sanctions regime maintains an administrative review mechanism through which legacy narcotics designations under the Foreign Narcotics Kingpin Designation Act (SDNTK) and related authorities (SDNT) are periodically re-evaluated and removed. The simultaneous issuance of terrorism-related designations, sectoral financial updates, amended interpretive guidance such as FAQ 1257, and narcotics-related delistings underscores the dynamic recalibration of statutory enforcement priorities.
The regulatory convergence around digital assets reflects a broader geopolitical friction point: sovereign authorities attempt to isolate capital access, while non-state networks and state-affiliated commercial brokers establish parallel offshore rails. Commercial registries and digital asset ledgers documented in government disclosures show that corporate creation dates for targeted nodes cluster heavily between 2019 and 2025, revealing rapid deployment cycles designed to outpace administrative enforcement actions.
Key Actors: Profiles and Jurisdictional Footprints
Central Facilitators and Financial Anchors
The enforcement documentation highlights several high-profile individuals acting as operational focal points within these transnational networks. Prominent among them is Siavash Kayvanpour (also operating under aliases such as Siavash Hashem, Siavash Kaivanpour, and Siyawesh Kiwan Port), identified with ties to Kish, Iran, and Dubai, United Arab Emirates. Kayvanpour possesses multi-jurisdictional identity documentation, holding citizenship in Iran alongside alternative recorded nationalities in Afghanistan and the Commonwealth of Dominica, supplemented by an official UAE identity number (784-1979-5841714-5) and a Dominica passport (RA003752).
Kayvanpour is formally designated under Counter Terrorism authorities [SDGT] with direct linkage to the [[Islamic Revolutionary Guard Corps|Q272583]] (IRGC) and secondary sanctions exposure under Executive Order 13224 as amended. Public records explicitly bind his identity to multiple digital asset receiving addresses across four independent blockchains: Bitcoin (addresses 15Zt2mKuQ5Qy6DEXfDcbtsEVneoGQQXrS4 and 1BUXxhcwzFukm9CUxnhag85sSXDkMRbXse), Ethereum (0x8d79c73daae8630c88de372ba8f57592fa987607), and Tron (TPgxjjB6AJeMSQFngbUM6dMMxPHa9GEtYa).
Additional individuals designated under sectoral authority E.O. 13902 include Saeed Ghasempour (born February 10, 1980, in Babol, Iran), cited for structural linkages to the major financial institution Bank-e Shahr. Amir Hendi (born November 5, 1982, in Tehran) is formally designated due to direct operational connections to Titan Exchange. Further designated Iranian nationals subject to secondary sanctions include Peivand Mohammad, linked to Farab Soroush Afagh Qeshm Company, and Shima Sharifi (born June 28, 1992, in Tehran).
The Exchange Infrastructure and Shell Network
Corporate listings in the administrative record span regulated free zones and offshore entities operating as virtual asset exchanges or wholesale trading companies. In Tehran, Aban Tether Exchange (Aban Tabadel Arsabaran, abantether.com), established on August 26, 2020, stands designated as a domestic financial and insurance entity. Operating externally from Dubai, Titan Exchange (also registered under Titan Energy Petroleum Products Trading Co. L.L.C and Titan Land Petrochemicals Trading L.L.C) maintains multi-tiered local commercial licenses while maintaining institutional links to Bank-e Shahr.
A critical cluster operates under the “Shelbit” and “Crypto Home” corporate families across the UAE, Eastern Europe, and the Caucasus. Crypto Home DMCC (established March 8, 2022, in the DMCC Business Centre, Dubai) and NFT Home DMCC (established May 19, 2022) were designated under SDGT authorities, with Crypto Home DMCC tied directly to digital currency addresses across Bitcoin (1G1V1b9s9uPsFCNL15ibZk44xsVygKsP2u), Ethereum (0xbb69e01921b17cd22080968bcc96ba6115da6062), Binance Chain (bnb136ns6lfw4zs5hg4n85vdthaad7hq5m4gtkgf23), and Tron (TTVJuXWCusAURrpNShiypauagEH1N4CrxV).
The Shelbit corporate apparatus exhibits an extensive international footprint:
- Shelbit General Trading LLC: Based in Dubai, UAE (Registration No. 3334083), designated under terrorism sanctions.
- Shelbit Technologies Ltd Spolka z Ograniczona Odpowiedzialnoscia w Likwidacji: Based in Warsaw, Poland (established August 24, 2023; Tax ID 5214033324, REGON 526184547, KRS 0001053647), designated under monetary intermediation classifications.
- SHPS Shelbit (Shelbit Exchange): Operating from Tbilisi, Georgia (established April 29, 2025; Registration No. 400430477; shelbit.com), designated with public digital currency addresses across Bitcoin (

Complementing this crypto-focused infrastructure are trading companies across East Asia and the Gulf designated under E.O. 13902: Alps International L.L.C-FZ (Dubai), Aydeniz General Trading L.L.C (Dubai), Blue Dash General Trading Company Limited (Kwun Tong, Hong Kong), Gleaming HK Trading Limited (Kwun Tong, Hong Kong), Oviedo Overseas Company Limited (Kwun Tong, Hong Kong), and Cailafang Pte. Ltd. (Paya Lebar Square, Singapore).
Counter Narcotics Designations Removals
The administrative record simultaneously details significant removals from the Specially Designated Nationals (SDN) list under counternarcotics authorities (SDNT and SDNTK). In Colombia, Mario German Satizabal Rengifo (known as “Pelo de Cobre”) and Rubi Yiceth Ayala Barrera (linked to Herjez Ltda.) have had their sanctions restrictions rescinded.
In Mexico, an extensive network centered on maritime logistics and refrigerated seafood trading was formally removed from the sanctions register. This cluster includes Heriberto Zazueta Godoy (known as “Capi Beto”), Leopoldo Zazueta Gomez, and Demetrio Romero Zevada, along with three associated commercial maritime entities based in Sinaloa and Jalisco: Produccion Pesquera Dona Mariela, S.A. de C.V., Taipen, S.A. de C.V. (also operating as Tai Pen), and Comercializadora y Frigorificos de la Perla del Pacifico, S.A. de C.V.
Critical Analysis of the Evidence
The factual configuration embedded in the administrative record exposes the mechanics of modern value intermediation. Rather than operating isolated domestic exchanges, the networks identified rely on physical corporate anchors dispersed in jurisdictions known for rapid commercial incorporation—such as the DMCC in Dubai, Hong Kong industrial sectors in Kwun Tong, and Poland’s national court register—to bridge traditional fiat commerce with borderless blockchain settlement.
“Additionally, OFAC has updated the Specially Designated Nationals and Blocked Persons List… issuing an amended Iran-related Frequently Asked Question, FAQ 1257.”
The inclusion of specific wallet addresses spanning Bitcoin, Ethereum, Tron, Binance Chain, and Solana across both individual actors (Kayvanpour) and operational platforms (Crypto Home DMCC, SHPS Shelbit) provides verifiable forensic data points. The presence of multi-chain receiving addresses demonstrates that these entities do not operate as simple single-asset custodians; they function as cross-chain settlement hubs capable of handling diverse liquidity pools.
However, the documentation leaves critical investigative questions open. While corporate registration numbers, tax identifiers, and public addresses are cataloged, the evidentiary filings do not disclose the gross volume of capital transferred across these specific wallets prior to designation. Furthermore, the operational connection between physical trading shells (such as Hong Kong-based Blue Dash and Gleaming HK) and the digital asset exchange hubs remains structural rather than transactional within the public text.
The simultaneous de-listing of Colombian and Mexican maritime seafood companies (Produccion Pesquera Dona Mariela, Taipen, Comercializadora y Frigorificos de la Perla del Pacifico) highlights the distinct procedural nature of administrative sanctions. Delistings occur when designated entities demonstrate verifiable corporate dissolution, structural severance from illicit facilitators, or successful administrative appeals, representing an operational closure on legacy maritime narcotics tracking while digital financial enforcement expands.
Transparency and Legal Framework
The evidentiary record underpinning this dossier originates directly from public regulatory action announcements issued by the United States Department of the Treasury’s [[Office of Foreign Assets Control|Q192997]] (OFAC), published on August 7, 2026. The statutory basis governing the publication of these executive determinations resides under United States sanctions legislation and executive orders, operating within the public disclosure standards established under Title 17, United States Code, Section 105 (17 U.S.C. § 105), which places official U.S. government administrative records in the public domain.
The administrative record details specific statutory authorities invoked for each individual and corporate entry, primarily Executive Order 13902 (targeting specific sectors of the Iranian economy) and Executive Order 13224 as amended by Executive Order 13886 (counter-terrorism and secondary sanctions risk), alongside legacy authorities under the Kingpin Act. The complete, unedited public register of these designations, modifications, and removals is maintained permanently in the Treasury’s official sanctions archive at https://ofac.treasury.gov/recent-actions/20260807.
