Dubai Regulator Issues Reprimand to OPNX Founders
The Virtual Assets Regulatory Authority (VARA), the regulator that concerns itself with the digital assets market in the Emirate of Dubai, has formally reprimanded the founders of digital asset exchange OPNX.

VARA issued an investor and marketplace alert on April 12 to inform investors that OPNX was not a licensed entity regulated by VARA and with that, it urged investors to be cautious. The regulator has now gone one further, this time formally writing to OPNX’s founders to reprimand them.
The statement cites the following rationale for the issuance of the reprimand:
”Carrying out VA (Virtual Asset) Exchange Services on an unregulated basis in and from the Emirate of Dubai; and Marketing, promoting and/or advertising OPNX services and its native token [FLEX] without the necessary permits from VARA.”
Contextual background
The statement goes on to provide the context for the regulator’s most recent action. VARA became aware of OPNX soliciting the public to use the exchange in February of this year. It noted that the business was actively marketing through various social media channels “without establishing warranted restrictions for residents of Dubai/UAE.” VARA went on to explain that OPNX commenced trading in April without having secured a regulatory license despite the activity warranting such a license.
Cease and desist
On February 27, VARA issued OPNX with a cease and desist order, relative to the foundation of the business and the marketing and promotion of services. Thereafter, the exchange applied certain restrictions but the regulator deemed the measures to not have been applied comprehensively across all OPNX communication channels, prompting it to issue a further cease and desist order the following month.
The investor and marketplace alert followed in April as OPNX proceeded to launch its exchange. The written reprimand was then issued on April 18, “to address historical and ongoing activity conducted on an unregulated basis.” The recipients included the OPNX founders, (Mark Lamb, Sudhu Arumugam, Kyle Davies and Su Zhu) and the firm’s CEO Leslie Lamb.
Given what the regulator deems to have been “a continued lack of satisfactory remedial action [taken] by the responsible parties,” it is continuing to actively monitor the situation. VARA stated that it will further investigate OPNX’s activity to assess further corrective measures that may be required to protect the market.
Lack of industry support
The digital assets industry is in no way enamored with founders Davies and Zhu. Their record has been badly blemished by the unceremonious collapse of their crypto hedge fund, Three Arrows Capital, in 2022. That failure wreaked major damage on the overarching crypto space, directly leading to the failure of other crypto businesses later that year.
Prominent crypto venture capitalist Michael Arrington said of their capital raise for OPNX that it was “the saddest bulls**t I’ve heard in a long time.” It later transpired that two of the investment firms that OPNX suggested were backing the start-up refuted the claim.
In response to this latest development, OPNX’s CEO Leslie Lamb told Blockworks that the business was initially launched in Hong Kong. “To confirm, we have no Dubai or UAE customers and do full KYC on all users,” she stated.
