SBI Holdings unveils Layer 1 proof of concept for tokenized stocks co-developed with Startale Group
SBI Holdings and Startale Group are building Strium, a bespoke Layer 1 blockchain focused on tokenized real-world assets and securities.Summary
SBI Holdings, a major Japanese financial firm, is collaborating with Startale Group, the R&D firm behind Sony's Layer 2, to develop Strium, a new Layer 1 blockchain specifically designed to support tokenized real-world assets, particularly securities.
Strium aims to serve global capital markets with a blockchain-native exchange architecture, promising faster market formation, deeper liquidity, and 24/7 access, differentiating itself from crypto-native platforms by focusing on traditional assets. This builds upon their prior August 2025 announcement to create a round-the-clock RWA trading platform offering near-instant cross-border settlement and fractional ownership.
The proof-of-concept, unveiled alongside the announcement, will demonstrate technical capabilities like settlement efficiency and resilience. Startale Group's founder, Sota Watanabe, views tokenized stocks as the largest opportunity in finance, merging traditional equity trust with DeFi's composability. The network is positioned as the foundational layer for Asia’s onchain securities markets, potentially leveraging SBI's extensive customer base.
