The RWA ecosystem is one of the fastest-growing in the digital assets market. Total RWA, including fiat-backed stablecoins, is estimated to be well over $230 billion, with projections suggesting the market could reach $3 to $30 trillion by 2030.
Startale and SBI Holdings are now expanding their presence in this ecosystem with the launch of Strium.
Startale and SBI Holdings Launch Strium
Startale Group and SBI Holdings, Inc. have announced the launch of Strium Network (“Strium”). In a press release shared with Cryptowisser, the teams said Strium is the brand identity and platform vision for their joint venture focused on building Asia’s exchange-layer infrastructure for tokenized securities and onchain real-world assets (RWAs).
This latest development represents the first major milestone from the strategic partnership announced in August 2025, with a proof of concept currently ready to demonstrate the platform’s foundational capabilities and validate its approach to delivering institution-ready onchain capital market infrastructure.
The teams added that the launch of Strium represents a shared effort to develop a purpose-built platform for trading and settlement of tokenized securities, designed to support both tokenized equities and RWA-linked instruments through 24/7 spot and derivatives trading markets.
Strium is focused on serving global capital markets through a blockchain-native exchange architecture, advancing faster market formation, deeper liquidity, and scalable global access without the constraints of direct asset issuance or custody.
The layer-1 blockchain will leverage SBI Holdings’ ecosystem of more than 80 million existing customers and expertise across securities, banking, and financial services, enabling it to bridge institutional demand, professional trading activity, and real-world market participation onchain.
Atrium will serve as the Exchange Infrastructure for Onchain Securities
The teams noted that Strium addresses a fundamental shift underway in institutional and professional markets. Atrium enables securities-linked spot and derivatives markets that operate beyond traditional banking hours through on-chain-native mechanisms, supporting faster price discovery, continuous trading, and scalable liquidity.
Designing it as the core exchange-layer for Asia’s onchain securities market, Strium will provide the rails for tokenized securities and RWA-linked instruments to scale globally while remaining interoperable with global financial systems.
Strium will empower institutional and professional participants to access, trade, and unlock assets in ways that were previously constrained by traditional market structures. The current proof-of-concept phase validates these core technical assumptions and demonstrates the platform's ability to deliver on this vision.
Proofs of Concept Delivered
The teams added that the launch of the Strium brand coincides with the proofs of concept (“PoC”) developed in parallel. PoC is now ready for internal presentation to validate the platform’s exchange architecture, settlement efficiency, and interoperability with both traditional financial infrastructure and blockchain networks.
Strium’s upcoming testnet will soon allow early participants a first look at its Layer 1 blockchain powering tokenized securities and RWA markets.
What Next for Strium?
The Strium brand represents a long-term commitment by Startale and SBI Holdings to shaping the future of onchain capital markets.
According to the teams, the current PoC phase is crucial in validating this vision and building the foundation for a platform that can deliver on these ambitious goals.
