UQPAY Launches Fiat-to-Stablecoin Payment Stack
Singapore-based UQPAY has launched a full-stack payment infrastructure designed to bridge traditional fiat currencies and stablecoins. The platform unifies global acquiring, card issuing, and stablecoin accounts into a single system for global commerce.
UQPAY's fintech infrastructure, which supports over 200 markets and 140 currencies, is built on a "dual-rail" architecture. This system integrates traditional payment rails, such as card networks and SWIFT, with blockchain-based infrastructure for stablecoin transactions. For developers, this means a single API integration can handle both conventional fiat and multi-chain stablecoin payments. The company was founded by CEO Li Wangjian, a graduate of Zhejiang University's Department of Computer Science and Technology. Li is a serial entrepreneur and an early advocate for blockchain technology, with a history of exploring its application in cross-border payments since at least 2018. From a system design perspective, UQPAY's platform is engineered to centralize payment orchestration, liquidity management, and reconciliation for businesses. The infrastructure is designed for high-growth sectors like e-commerce, SaaS, and gaming, providing tools for subscription billing, multi-currency treasury management, and global expense management through its card issuing services. UQPAY provides API documentation and SDKs in languages like Go and PHP, available on its GitHub repository. Recently, UQPAY's Australian division launched a stablecoin acquiring platform compatible with the Universal Commerce Protocol (UCP) and the AI-native x402 payment standard. This platform is designed for both traditional merchant payments and autonomous transactions initiated by AI, supporting stablecoins like USDC, USDT, and XUSD. Instead of pursuing traditional venture capital funding, UQPAY is also positioning itself as a strategic investor in the fintech space. The company recently obtained a Capital Markets Services (CMS) License from the Monetary Authority of Singapore to launch a private equity fund targeting the fintech sector. In a significant move, UQPAY made a $10 million strategic investment in StraitsX, a Singapore-based stablecoin settlement firm, to enhance connectivity between fiat and stablecoin networks across Asia.
