CoinFLEX founder: creditors not to interfere with OPNX
Mark Lamb, the co-founder of failed crypto derivatives and yield platform CoinFLEX, has asserted that creditors of the company cannot interfere with OPNX, a Seychelles-incorporated company that Lamb has co-founded with Kyle Davies and Su Zhu, the founders of failed Singaporean crypto hedge fund, Three Arrows Capital (3AC).

Fallout following writ
It emerged in October that a group of CoinFLEX creditors had filed a writ of summons in the High Court of Hong Kong, claiming that OPNX, a new crypto bankruptcy claims trading platform linked to CoinFLEX, was established using CoinFLEX assets without their consent. While incorporated in the Seychelles, CoinFLEX ran its operations from Hong Kong.
The writ alleges that Mark Lamb misappropriated assets, diverted clients and business opportunities and engaged in actions harmful to creditors during his tenure.
The creditors argue that Lamb, while serving as CoinFLEX’s CEO, simultaneously devoted time and effort to setting up OPNX, contrary to his responsibilities. The allegations include diverting assets, falsely representing OPNX’s association with CoinFLEX creditors, disclosing confidential trade secrets and soliciting employees to move to OPNX.
The legal action — filed by two companies, Liquidity Technologies and Liquidity Technologies Software — claims that OPNX’s formation was unauthorized and harmful to CoinFLEX creditors. Despite CoinFLEX’s terms of service requiring dispute resolution through arbitration in Hong Kong, the allegations have not been proven in the High Court of Hong Kong.
Lamb addresses ‘Twitter FUD’
In response to these creditor actions, earlier this week, Lamb took to X (formerly Twitter) to address what he termed as “Twitter FUD.” Lamb wrote:
“The Hong Kong court ruled that the few CoinFLEX creditors behind recent ‘FUD’ must not disrupt or interfere with OPNX in any way — and their legal counsel has subsequently stopped representing them.”
Lamb added that he hoped that CoinFLEX’s 4,800 creditors would choose the path that he has proposed on the basis that it “maximizes value.”
OPNX has defended its position, emphasizing that it provided an opportunity for creditors to sell their claims on the exchange for quick cash, benefiting them. Davies and Zhu have pledged to donate their share of the profit to 3AC creditors.
In February, OPNX CEO Leslie Lamb, Mark Lamb’s wife, announced the rebranding of CoinFLEX to Open Exchange (OPNX). However, the writ of summons claims that OPNX is a separate entity not authorized by CoinFLEX creditors. Leslie Lamb followed up in April by claiming backing from well-known entities in crypto venture capital, only for many of those mentioned to immediately refute such claims.
The dispute has also implicated Roger Ver, a well-known character in the crypto space otherwise referred to as “Bitcoin Jesus.” Ver, a significant individual customer, was accused of defaulting by CoinFLEX. Ver denied defaulting and claimed that CoinFLEX used his trading positions against him, leading to a court-ordered arbitration.
OPNX, since its launch in April, has obtained a Lithuanian license for spot trading in the EU and currently processes substantial daily trading volumes. Criminal and civil proceedings against OPNX co-founders Davies and Zhu are ongoing. The situation remains fluid as the legal dispute unfolds.
