SBI and Startale Launch Strium Network — Layer‑1 for 24/7 Tokenized Securities and RWAs

SBI Holdings and Startale Group have launched Strium Network, a Layer‑1 blockchain designed as an exchange and settlement layer for 24/7 trading of tokenized securities, derivatives and real‑world assets (RWAs). Building on a strategic partnership announced in August 2025, the project completed multiple proof‑of‑concepts validating settlement design, high‑load resilience and interoperability with legacy financial systems and other blockchains. Strium initially supports synthetic US and Japanese stocks and commodity‑linked instruments, with plans to add tokenized shares and asset‑backed tokens that require identity verification and compliance checks; a separate open layer will permit broader participation without those requirements. SBI contributes regulated financial infrastructure and access to over 80 million customers across securities, banking and finance in Asia, positioning Strium as a potential institutional base layer for regional tokenized capital markets. The platform separates trading infrastructure from issuance and custody, targets faster price discovery and deeper liquidity versus traditional banking‑houred markets, and plans to enable AI trading agents to interact with on‑chain liquidity. A public testnet is expected soon as the project moves from PoC to wider testing and regulatory discussions in target markets, including Japan. For traders: Strium could expand institutional on‑chain liquidity and trading hours for securities‑linked products, raise competition among tokenized stock initiatives and influence flow between centralized exchanges and on‑chain venues — monitor testnet performance, regulatory updates and listings to assess execution risk, custody arrangements and possible new instruments that could affect cross‑market arbitrage and liquidity.
