RevDuck’s “Jewels Scam”: How Lyntec on Great Portland Street Powers an Affilka-Backed Illegal Casino Network

A coordinated “Jewels” operation involving Ukrainian nationals, London-based shell companies, and the SoftSwiss-powered RevDuck network has been unmasked. New evidence reveals how Lyntec Limited acts as a financial front for illegal fiat deposits, masking gambling transactions as “IT consultancy” services.

The intelligence trail connects the HolyLuck / TrueLuck / Booms.bet casino cluster to a tightly controlled offshore operation fronted from London’s Great Portland Street – and wired into the SoftSwiss/Affilka infrastructure FinTelegram has already exposed. What looks like a loose affiliate constellation increasingly resembles a coordinated “Jewels” payment and branding scam operated by Ukrainian controllers.

“GEMCEBR”: Decoding the Transaction Laundering

Player bank statements show the descriptor “GEMCEBR LONDON GBR” on deposits that in reality fund unlicensed casinos such as HolyLuck and TrueLuck, not any legitimate “gems” marketplace. A key discovery in this intelligence report is the bank descriptor “GEMCEBR LONDON GBR.” This is a textbook example of Transaction Laundering (TL).

• The Mask: The descriptor mimics the name of the legitimate “Centre for Economics and Business Research” (CEBR) to avoid scrutiny from bank compliance algorithms.
• The Reality: The “GEM” prefix acts as a internal corporate signature for the “Jewels” syndicate, which includes offshore entities like Sapphire Summit S.R.L. and Gem Limitada.
• Independent player-discussion threads list “GEMCEBR, London” among descriptors encountered in disputes tied to Curaçao-licensed gambling sites and merchant-category concerns.

This mirrors FinTelegram’s earlier findings that the RevDuck network reuses Sapphire Summit S.R.L. (reg. no. 3‑102‑903325) across multiple brands and regulatory actions, including the KSA fine against Booms.bet (read more about the TrueLuck sister sites here).

The Great Portland Street Pipeline

The network utilizes the “virtual office” hub at 167-169 and 85 Great Portland Street, London to create a veneer of UK legitimacy.

• Lyntec Limited (Company No. 15919943): Incorporated in August 2024, this entity is registered as an “IT consultancy.” Our research confirms it is controlled by Ukrainian nationals Maksym Buriachenko and Kyrylo Lehkodukh (until Nov 2025).
• The Shell Strategy: By registering as a consultancy, Lyntec can access the traditional banking system to process fiat deposits that would otherwise be flagged as high-risk gambling transactions.

In FinTelegram’s risk taxonomy, such “IT/marketing” façades on Great Portland Street are typical of transaction‑laundering fronts that disguise gambling flows as benign B2B services.

Ukrainian Control and the RevDuck–Lyntec Link

The whistleblower’s claim that both “brains” (RevDuck) and “wallet” (Lyntec) are Ukrainian-controlled finds partial confirmation. Independent industry sources and FinTelegram’s previous RevDuck dossier describe RevDuck’s operational teams as Ukrainian and deeply embedded in the SoftSwiss/Affilka ecosystem.

While public records do not (yet) formally link RevDuck and Lyntec, the shared nationality pattern, matching Great Portland Street environment, and overlapping casino cluster are strong circumstantial indicators of a coordinated structure rather than independent actors.

Transaction Laundering via Lyntec and the SoftSwiss Layer

From a compliance perspective, the GEMCEBR descriptor and London “IT consultancy” cover point to classic transaction laundering:

• Players from restricted markets (e.g., the Netherlands) deposit in fiat under a neutral London descriptor.
• Lyntec appears as the merchant of record, masking the underlying gambling nature from banks and card schemes.
• Funds are then routed to offshore operators such as Sapphire Summit S.R.L. (Costa Rica) and linked “Gem” entities behind TrueLuck, HolyLuck, and Booms.bet.

FinTelegram’s earlier report already documented that RevDuck operates on SoftSwiss’s Affilka platform, with Affilka providing the tracking, reporting, and affiliate payment backbone for this cluster. The Lyntec thread now suggests that, in addition to crypto/payment rails linked to SoftSwiss’s broader “payment hub” allegations, dedicated UK shells are spun up to handle card traffic under misleading descriptors.

Key Data

Conclusion and Call for Information

The portrayal of RevDuck as “just an affiliate” is no longer credible. The jewel‑themed branding, the reuse of Sapphire Summit S.R.L., the Great Portland Street shell setup, Ukrainian beneficial ownership of Lyntec, and the Affilka integration together indicate a single, highly structured illegal iGaming enterprise, not a decentralized network.

FinTelegram will continue to investigate Lyntec Limited (15919943), the GEMCEBR descriptor, and associated banking partners as potential transaction‑laundering channels for the RevDuck/SoftSwiss ecosystem.

Industry insiders, current or former employees of Lyntec, RevDuck, SoftSwiss/Affilka clients, processors, or banks seeing GEMCEBR‑tagged flows are urgently invited to submit documents and intelligence via the secure Whistle42 platform. All submissions will be treated confidentially and may be decisive in enabling regulators and law enforcement to shut down this network.
