SoftBank Chain (SBC) has introduced Interstellar, a next-generation solution aimed at modernizing Web3 payments and advancing Open Finance infrastructure. Developed to connect decentralized blockchain systems with conventional financial institutions, Interstellar is positioned as a key tool in delivering secure, seamless, and scalable digital payment experiences for developers and end-users across the globe.
Operating as a core part of SBC’s broader blockchain initiative, Interstellar represents a pivotal move toward integrating artificial intelligence and low-latency architecture into financial protocols. SBC itself functions as the blockchain arm of SoftBank, leveraging its parent company’s global communication networks and data centers. This synergy supports a full spectrum of services, including compliant international payments, asset tokenization, smart contract execution, and large-scale Open Finance operations.
Interstellar’s foundational objective lies in constructing a universally accessible blockchain-based financial system. The platform seeks to bridge the gap between digital assets and real-world assets (RWA), creating a comprehensive financial infrastructure that benefits users at all levels. The Interstellar ecosystem comprises several key components: a global payments network, a native stablecoin named USDX, a modular Open Finance layer branded as PayFi, and integrated AI computational power. Combined with SBC’s blockchain framework, these elements form a unified solution for efficient financial engagement.
PayFi, a central element within Interstellar, offers tailored advantages for multiple user groups. Wallet holders can utilize it to generate passive returns from their digital holdings, while merchants gain the ability to accept permissionless, international payments. Furthermore, developers have the opportunity to build decentralized financial applications (dApps) that tap into Interstellar’s ecosystem-wide liquidity. This modular framework promotes open access and encourages innovation across the decentralized finance (DeFi) sector.
The system is further enhanced by its technological backbone. Interstellar employs a unique combination of AI-driven compute clusters and a low-latency blockchain architecture. This design enables features such as real-time payment processing, automated contract-based workflows, and fully transparent, on-chain settlement auditing. The infrastructure ensures not only speed and scalability but also accountability in financial transactions.
USDX, Interstellar’s native stablecoin, is pegged to the US dollar at a 1:1 ratio. It has been engineered to deliver high liquidity and minimal price volatility, serving as a digital counterpart to fiat cash. Integrated with both SBC Pay and the PayFi ecosystem, USDX enables a wide range of functions including retail payments, asset swaps, and smart contract settlements. Its stable value proposition aims to reduce risk and improve usability within everyday financial applications.
The ecosystem is powered by SBC Pay, a digital wallet purpose-built for Web3 transactions. Designed with AI-based security protocols and embedded blockchain capabilities, SBC Pay supports cross-border payments and remittances within seconds. The wallet is also integrated with fiat on- and off-ramp systems, as well as international licensing frameworks, ensuring regulatory compliance and broad accessibility. It enables seamless real-time asset movement across platforms, regardless of a user’s location, identity, or financial status.
With Interstellar, SBC has signaled its commitment to shaping the future of decentralized finance through a combination of advanced technologies, robust infrastructure, and inclusive financial solutions. The platform’s convergence of AI, blockchain, and global compliance may pave the way for more transparent, secure, and user-centric financial ecosystems in the Web3 era.
