SBI Remit and Shonan Shinkin Bank Join Forces on International Remittances

OPNX Enables Margin Trading via oUSDCrypto 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.Photo by Krišjānis Kazaks on UnsplashSolving three problemsThe 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 plansLamb 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.

Iranian authorities last week introduced new restrictions on stablecoin transactions, limiting individuals to an annual purchase cap of $5,000 and a total holding limit of $10,000. According to a report from Iran International, licensed digital platforms have one month from the effective date to enforce these new regulations on all users.Photo by Hadis Malekie on UnsplashRial decline fuels stablecoin uptakeThe move coincides with the continued devaluation of the national currency, with the Iranian rial reaching an all-time low of 1,136,500 per U.S. dollar on Sept. 27. This currency plunge occurred just before the reimposition of United Nations sanctions, which took effect at 00:00 UTC on Sept. 28. Since then, the rial has weakened further, reaching a new low of 1,170,000 per U.S. dollar as of publication, as per data from Bonbast.  For many Iranians, stablecoins like USDT have become an essential financial tool, providing a hedge against inflation and a means to transfer funds internationally, bypassing the traditional banking system. The adoption of these U.S. dollar-pegged digital assets has reportedly grown since the escalation of conflicts with Israel and the U.S. earlier in the year. These new financial controls follow recent actions by the U.S. to counter what it describes as Iranian "shadow banking" networks. On Sept. 16, the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) sanctioned two Iranian financial operatives and their network of companies in Hong Kong and the United Arab Emirates (UAE). A press release stated these entities used cryptocurrency and front companies to transfer funds from oil sales, benefiting Iran’s IRGC-Qods Force (QF) and its Ministry of Defense and Armed Forces Logistics (MODAFL). The U.S. Treasury asserts these funds are funneled into regional proxy groups and the development of advanced weapons programs.U.S. dollar to rial chart Source: BonbastHack on Iran’s top crypto platformIran’s private digital currency sector has also faced mounting security pressures. In June, Nobitex, the country’s largest crypto exchange, was hit by a major exploit that drained about $90 million in assets, including Bitcoin (BTC), Ethereum (ETH), Dogecoin (DOGE), Ripple (XRP), Solana (SOL), Tron (TRX), and TON. A pro-Israel hacker group known as Predatory Sparrow, or Gonjeshke Darande, later claimed responsibility in a post on X. The attack took place during heightened military tensions that began with Israeli strikes on Iranian military and nuclear facilities on June 18, 2025. According to analysis by TRM Labs, digital assets are increasingly integral to Iran's efforts to navigate international sanctions and advance its geopolitical interests. Iranian exchanges, including Nobitex, process billions in cryptocurrency transactions. These platforms have been noted for permitting large withdrawals without stringent Know Your Customer (KYC) protocols and for employing sophisticated methods to obscure the origins and destinations of funds. At the same time, these exchanges are not used solely for state-level purposes. For many ordinary Iranians, grappling with inflation and economic isolation, digital assets represent a practical tool for safeguarding savings and maintaining limited access to the global economy, underscoring the dual role that cryptocurrency plays in the country.
