OPNX Enables Margin Trading via oUSD

Web3 & Enterprise·July 05, 2023, 11:48 PM

Crypto futures and bankruptcy claims trading exchange OPNX has unveiled a credit currency called “oUSD” for margin trading.

The company announced the new currency via a statement to Cointelegraph by OPNX Co-Founder Mark Lamb on Wednesday. The initial phase of oUSD requires users to deposit crypto assets into the exchange to acquire the currency. In the subsequent phase, OPNX plans to enable users to obtain oUSD by depositing crypto into on-chain contracts, allowing for potential “bankruptcy remoteness,” according to Lamb.

Solving three problems

The currency’s litepaper identifies three problems that oUSD aims to solve. Firstly, lenders are hesitant to trust platforms to hold cash loans backed by crypto collateral. Secondly, exchanges and lending platforms are wary of lending cash to margin traders due to the multiple bankruptcies witnessed during the bear market of 2022. Lastly, crypto derivatives traders seek “portfolio margin” to borrow and trade based on their crypto holdings rather than stablecoin holdings.

To address these concerns, oUSD is designed as a “credit currency.” It can be obtained at a 1-to-1 ratio with Tether (USDT) or used to measure profit and loss when users utilize Bitcoin or other cryptocurrencies as collateral. Users with negative oUSD balances are subject to an interest rate determined by holders of the platform’s native token, OX. Those with a positive balance can redeem oUSD for USDT.

 

Future plans

Lamb discussed future plans with Cointelegraph, explaining that users will eventually be able to acquire oUSD by staking cryptocurrencies within smart contracts outside the platform. This mechanism aims to provide bankruptcy remoteness, safeguarding users from potential exchange insolvency.

One of the co-founders of OPNX, Kyle Davies, along with Su Zhu, also co-founded the failed hedge fund Three Arrows Capital (3AC), leading to controversy surrounding the exchange. OPNX’s CEO, Leslie Lamb, admonished investors for allegedly misleading the public by disassociating themselves from the exchange. Responding to criticism, Mark Lamb argued that the mistakes made by Davies and Zhu have contributed to improving OPNX as an exchange.

Lamb stated: “I think Kyle and Su kind of portrayed the zeitgeist of the last crypto bull market well, and they lost the majority of their net worth, but they are building back, and that’s what I am doing as well, and that’s what everyone should do… just build back.”

Appearing on a Twitter Spaces recently, the founders of the bankrupt Singapore-headquartered 3AC said that they are committed to donating future earnings from OPNX to the creditors of the collapsed crypto hedge fund. Goodwill has been largely lacking for the duo following the 3AC collapse yet undeterred, they are putting all their energies behind their new venture, OPNX.

OPNX’s launch of oUSD as a credit currency offers potential solutions to the challenges faced by lenders, exchanges, and margin traders in the crypto space. By introducing oUSD, OPNX aims to provide a safer trading environment, provable solvency, and custody on-chain, giving users protection for their assets and promoting trust in the exchange. Trust might be in short supply for the start-up’s founders although there’s no doubt that they have acquired a lot more experience in the wake of the 3AC collapse.

DWF Labs switches headquarters from Singapore to Abu Dhabi

DWF Labs, a Singapore-based crypto sector investment firm and market maker, has decided to move its headquarters to Abu Dhabi in the United Arab Emirates (UAE). Alongside its current offices and headquarters in Singapore, the company has established offices in Dubai, Hong Kong, Switzerland, South Korea and the British Virgin Islands (BVI).Photo by Adnan Uddin on PexelsFocusing on MENA growthIn an X post published on Dec. 2, DWF Labs Co-Founder Andrei Grachev announced the change of headquarters location from Singapore to Abu Dhabi, stating: “In order to build a strong presence in the Middle East and run more RWA [Real World Assets] and financial services there, @DWFLabs is moving the headquarter to Abu Dhabi.” Grachev added that more news in this regard will be announced soon, advising stakeholders to stay tuned regarding the matter. In the past, the DWF Labs founder has highlighted the significance of the Middle Eastern market.  Earlier this year, he suggested that the Middle East and North Africa (MENA) market is “one of the fastest growing markets in the world,” while commenting on the firm’s partnership with the Dubai Multi Commodities Centre (DMCC), a Dubai-based ecosystem for blockchain and distributed ledger technologies.  That isn’t the firm’s only partnership within the UAE. In September, it emerged that it had partnered with Abu Dhabi-based Web3 venture capital firm Klumi Ventures. The firms intend to collaborate in relation to the offering of strategic crypto advisory services in the UAE, investments and market making, market education and in the facilitation of over-the-counter (OTC) deals and crypto asset options. Strategic positioningAt the time, Grachev said that the two firms were “strategically positioned to drive the digital transformation in the UAE,” with the ability to empower both new market entrants and established institutions to succeed within the digital assets arena. It appears that Grachev has been spending a significant amount of time in Abu Dhabi of late. On Sept. 25, he posted on X that he had arrived in Abu Dhabi and was “cooking something special for the industry.” He followed up on that more recently, posting a selfie on X on Nov. 25 with the caption “Chef cooking in Abu Dhabi.” The authorities in both Dubai and Abu Dhabi, as well as Singapore, have all been working towards attracting crypto startups to their cities. All of them have had some success in that regard, although DWF Labs’ move away from Singapore indicates how competitive this environment is and how mobile crypto startups are. ADGM crypto hubIn the case of Abu Dhabi, most crypto sector activity has happened within the city’s international financial centre (ADGM), which has attracted projects such as the Kaia DLT Foundation, stablecoin issuer Paxos, blockchain infrastructure firm Blockdaemon, crypto custodian Liminal, crypto venture capital fund Token Bay Capital and many others. DWF Labs was first founded in Singapore in 2022. It has established ecosystem funds and grants relative to projects such as EOS, Floki, Gala Chain, Klaytn and TON. Additionally, the firm has just announced the launch of a $20 million fund focused on meme coin projects.

U.S.-sanctioned Huione Group suspected of supporting crypto transactions in Korea

A Cambodia-headquartered financial group recently cut off from the U.S. financial system is suspected of having operated in South Korea, raising fresh questions about cross-border crypto and currency flows tied to the group. According to the Dong-A Ilbo, which cited data from the Korea Customs Service (KCS), Huione Group—now sanctioned by the U.S. Treasury Department’s Financial Crimes Enforcement Network (FinCEN)—appears to have run a currency exchange in Seoul from 2018 to July 2024. The outlet reported that a banner on the premises displayed a logo identical to Huione’s, prompting suspicions about its ownership and control.Photo by Aleksandar Pasaric on PexelsTies to North Korean hackersThe exchange reported conducting roughly $20,000 in annual currency conversions during that period, excluding cryptocurrency transactions. The timeline overlaps with a period in which Huione Group reportedly received $150,000 in cryptocurrency from the North Korean hacking group Lazarus.  Connections also extend to Cambodia. Panda Bank—a local lender that shares a building with Huione subsidiaries—supports USDT transactions originating from South Korea. Panda Bank director He Yanming is listed as the owner of Huione Crypto, a virtual asset service provider (VASP), suggesting potential links between operations in Seoul and Phnom Penh. These developments come against the backdrop of a U.S. investigation disclosed in May, in which FinCEN said Huione’s business networks, including payments arm Huione Pay, collectively laundered at least $4 billion in illicit proceeds between August 2021 and January 2025. Crypto used in $2.6B illegal conversionsMeanwhile, recent KCS data also shows a rise in illegal currency conversions involving cryptocurrency by foreign nationals. The Korea Economic Daily reported conversions totaling 432 billion won ($302 million) in 2021, climbing to 836 billion won ($584.5 million) in 2023 and 956 billion won ($668.4 million) last year. Over the past eight years, the total amount involved in such cases reached 3.7 trillion won ($2.59 billion) across 28 instances. By value, Chinese nationals accounted for 84.1% of the total, followed by Australians (11.1%), Vietnamese (3.2%), and Russians (1.6%). The growing prevalence of cryptocurrency in illicit activity parallels a broader surge in crypto investment within the country. Many South Koreans have turned to digital assets, often with home ownership as a long-term goal. Trading on local exchanges, Bloomberg reported, is heavily skewed toward more volatile altcoins, which make up more than 80% of total volume.  That stands in contrast to global markets, where investors largely focus on Bitcoin and Ethereum, which together make up more than half of overall trading. The momentum in local crypto investment intensified after Donald Trump’s U.S. presidential victory, with crypto trading in Korea reaching $27 billion in December 2024, about 80% of turnover on the KOSPI stock index. The investigation underscores the growing challenge for regulators in tracking and containing cross-border financial networks that rely on cryptocurrency and informal money transfers. As crypto adoption deepens in South Korea and scrutiny widens abroad, authorities find themselves navigating an increasingly intricate intersection of financial opportunity, enforcement, and risk.
