SBI, Startale launch Strium blockchain to power tokenized securities
SBI and Startale launched Strium, a Layer 1 for 24/7 tokenized securities trading, with a yen stablecoin and testnet slated for 2026 to plug into Asia’s capital markets.
- Strium is a Layer 1 exchange-focused blockchain for tokenized securities, FX and real-world assets with high-throughput, low-latency settlement.
- SBI and Startale plan a regulated yen stablecoin issued by Shinsei Trust & Banking and distributed via SBI VC Trade from Q2 2026.
- The venture taps SBI’s 80m-user network, with a public Strium testnet scheduled later in 2026 as the partnership’s first major milestone.
SBI Holdings and Startale Group announced the launch of Strium, a Layer 1 blockchain designed for institutional trading of tokenized securities and real-world assets, according to a statement from the companies.
SBI Holdings developing blockchain networks
The blockchain network targets traditional capital markets integration with blockchain infrastructure, with emphasis on Asia’s regulated financial ecosystem, the companies said.
Strium supports institutional-grade trading across multiple asset classes, including foreign exchange, tokenized equities such as U.S. and Japanese stocks, and real-world assets, according to the announcement. The network is optimized for high-throughput, low-latency settlement in environments requiring transaction reliability and regulatory compliance.
The proof of concept demonstrates the platform’s ability to maintain system stability under heavy traffic, process transactions with high settlement efficiency, and interoperate with existing financial infrastructure, the companies stated. The features address cross-border settlement and post-trade reconciliation challenges.
The platform enables 24/7 trading and near-instant settlement across jurisdictions, according to the developers. The system incorporates advanced account abstraction to reduce wallet management complexity for retail participants while maintaining compatibility with decentralized finance applications.
SBI Holdings and Startale are developing a yen-denominated stablecoin for on-chain settlement, scheduled for launch in the second quarter of 2026. Shinsei Trust & Banking will issue the stablecoin, with distribution through SBI VC Trade, providing a regulated settlement asset for domestic and cross-border transactions.
The project represents the first major milestone of a strategic partnership announced in August 2025, according to the companies. SBI Holdings plans to leverage its customer base of approximately 80 million users to drive adoption of the Strium ecosystem.
A public testnet for Strium is expected to launch later in 2026, marking the next phase toward production deployment, the companies said.
