SBI unveils Layer 1 for tokenised stocks

SBI Holdings has unveiled a Layer 1 proof of concept for tokenised stocks, co-developed with Startale Group, as it pushes deeper into onchain securities.

The new blockchain, called Strium Network, is designed to support real-world assets and aims to serve as a foundational exchange layer for Asia’s onchain equities markets with round-the-clock trading.

“Unlike crypto native perpetual platforms focused primarily on digital assets, Strium is focused on serving global capital markets through a blockchain-native exchange architecture,”

The Strium team said in an announcement.

SBI and Startale first announced their collaboration in August 2025, initially targeting a 24/7 tokenised RWA trading platform offering fractional ownership and near-instant cross-border settlement.

The partners have also been working on a yen-denominated stablecoin intended for global settlement and institutional adoption.

Strium is expected to leverage SBI’s roughly 80 million customers and financial services expertise, while demonstrating settlement efficiency, high-load resilience and interoperability with traditional and blockchain systems.

The launch comes as interest in onchain equities accelerates globally, with crypto-native firms, fintech platforms and legacy exchanges all exploring tokenised stock trading models.
