bitcoin.com Adds UAE-Registered Stablecoin to Self-Custodial Wallet
Bitcoin.com has integrated USDU, a US dollar backed stablecoin registered with the Central Bank of the United Arab Emirates, into its self custodial wallet. The integration, announced on August 19, gives Bitcoin.com users on web and mobile access to USDU for holding, sending and receiving. Users will retain control of their private keys, while additional features such as swaps and buy and sell services are planned through third party providers. Key Takeaways USDU Expands Beyond Institutional Users USDU is issued by Abu Dhabi based Universal Digital Intl. Limited and operates as a Foreign Payment Token under the UAE Central Bank’s Payment Token Services Regulation. Universal said USDU became the first US dollar backed stablecoin registered by the UAE central bank under the framework when it received its registration in January 2026. The stablecoin is issued as an ERC 20 token on Ethereum and is backed 1:1 by US dollar reserves held at Emirates NBD and Mashreq. Universal also says the reserves undergo monthly independent attestations, with reports made available publicly. Bitcoin.com executive Corbin Fraser highlighted the importance of reserve transparency when discussing the integration. “People shouldn’t need to be forensic accountants to know what backs the stablecoin they hold.” Universal Digital is also regulated by the Financial Services Regulatory Authority in Abu Dhabi Global Market to issue fiat referenced tokens. However, USDU’s regulatory status does not mean it is approved for unrestricted payment use across every jurisdiction. bitcoin.com Plans Wider Usdu Functionality The initial Bitcoin.com Wallet integration is focused on basic stablecoin functionality. Users can hold USDU and transfer it directly from their self custodial wallets. Bitcoin.com plans to expand the offering with swap and buy and sell services through third party providers. The company has also said it intends to accept USDU for designated services and work toward enabling payments between users and merchants across its products. The rollout gives USDU access to a broader retail audience after earlier developments focused more heavily on institutional infrastructure. In July, Zodia Custody added support for USDU, allowing institutional clients to hold and transfer the stablecoin. A USDT USDU liquidity pool was also launched on Uniswap in August, providing another route for on chain liquidity. The Bitcoin.com integration therefore adds a consumer wallet distribution channel to USDU’s growing network of infrastructure and liquidity options. UAE Regulated Stablecoins Gain Wider Distribution The development comes as the UAE continues building a regulated framework for digital assets and payment tokens. For Bitcoin.com users, the main distinction is that USDU can be held without handing custody of the assets to Bitcoin.com. The wallet’s self custodial structure allows users to maintain control of their private keys while using a dollar denominated token for transfers. However, the integration does not mean every USDU feature will immediately be available to every user. Bitcoin.com said functionality and availability can vary depending on jurisdiction and the services provided by third party partners. The expansion also remains relatively early in USDU’s development compared with established dollar stablecoins. Its integration into Bitcoin.com gives the token a wider distribution channel, but the available information does not establish it as a major global stablecoin by market share or liquidity. Conclusion Bitcoin.com’s integration gives USDU a new route into the retail market through a self custodial wallet. The move combines regulated stablecoin infrastructure from the UAE with direct user control over digital assets. For Universal Digital, the partnership broadens distribution beyond institutional channels. For Bitcoin.com users, it adds a regulated dollar backed asset that can be held and transferred without giving up custody to the wallet provider.
South Korea Moves to Block Polymarket Over Gambling Concerns
South Korea has ordered access to Polymarket to be blocked after regulators determined that the crypto prediction market provides an illegal gambling environment for users in the country. The decision was made on Tuesday, August 18, following a review by the Korea Media and Communications Standards Commission. Authorities concluded that Polymarket’s event contracts could fall under provisions of South Korean law covering gambling and the operation of gambling venues. South Korean regulators focused on the financial consequences of those positions rather than how the platform is technically structured. Polymarket allows users to buy and sell positions based on the outcome of real world events, including elections, sports, economic decisions and weather. The value of a position changes as the market’s implied probability changes, with winning positions receiving payouts when an event is settled. Key Takeaways Regulators Reject Polymarket’s Noncustodial Argument Polymarket argued that its structure separates it from conventional gambling operators. During the regulatory process, the company said it had removed its Korean language service and did not accept payments in Korean won. The company also argued that transactions are noncustodial and conducted through smart contracts, meaning Polymarket does not directly take custody of users’ funds. South Korean authorities rejected that distinction. The commission said companies cannot avoid domestic law simply because of technical characteristics or the way their services are delivered. Regulators instead examined what users can actually do on the platform and how Polymarket operates its markets. They pointed to its role in creating markets, establishing trading rules, providing deposit and withdrawal mechanisms, settling positions and collecting transaction fees. The commission also highlighted markets linked specifically to South Korea, including one concerning rainfall in Seoul during August, as evidence that the platform could facilitate activity relevant to Korean users. Authorities consulted the National Police Agency, the National Gambling Control Commission and the Korea Sports Promotion Foundation before reaching their decision. The agencies reportedly concluded that Polymarket’s operations could fall within South Korean restrictions on gambling and similar betting activities. A Growing Regulatory Problem for Prediction Markets The South Korean action follows a regulatory review that began earlier this year. Authorities had been examining whether Polymarket’s prediction contracts constituted illegal gambling, while police also investigated local users over their participation in election related markets. South Korea is not alone in restricting the platform. France, Australia and Germany have also taken action against Polymarket, while other jurisdictions have raised concerns over its gambling implications. The issue is becoming more significant as prediction markets expand beyond traditional financial speculation. Platforms can now offer contracts covering elections, sports, weather, interest rates and other real world events. Supporters argue that prediction markets aggregate information and provide a market based view of expected outcomes. Regulators can take a different view when users put money at risk based on events whose outcomes they cannot control. That distinction is particularly important in countries with strict gambling laws. What the Block Means for Polymarket Blocking access may make it harder for Polymarket to serve South Korean users, but it does not necessarily remove the underlying technology from the internet. Because the platform uses blockchain infrastructure and noncustodial mechanisms, enforcement presents different challenges from shutting down a conventional centralized betting operator. For Polymarket, however, the growing number of restrictions creates a broader compliance problem. The platform must increasingly account for different national interpretations of prediction markets, gambling and financial products. The South Korean decision also sends a message to other decentralized applications: operating through smart contracts does not necessarily prevent regulators from applying local laws. Conclusion South Korea’s decision marks another significant regulatory challenge for Polymarket and the wider prediction market sector. The ruling shows that regulators may judge these platforms by the economic activity they facilitate rather than simply by whether they use blockchain or allow users to retain custody of their assets. As prediction markets continue expanding, the distinction between financial trading and gambling is likely to remain a major regulatory question. For decentralized platforms, South Korea’s approach is another indication that technical decentralization alone may not be enough to avoid restrictions imposed by national law.
