SBI Holdings and Startale Unveil Strium to Power Next‑Gen Tokenized Securities - Crypto Economy

TL;DR

• SBI Holdings and Startale Group launched Strium, a Layer 1 blockchain for trading and settlement of tokenized securities and RWAs in Asia.
• The network will prioritize high throughput, low latency, and reliable settlement, with support for tokenized equities, RWAs, and spot and derivatives markets.
• The roadmap includes a yen-denominated stablecoin for on-chain settlement and the launch of a testnet in 2026.

SBI Holdings and Startale Group unveiled Strium, a Layer 1 blockchain designed for the trading and settlement of tokenized securities and real-world assets. The project emerges as the first operational outcome of the partnership announced in August 2025 and is intended to function as an on-chain exchange and settlement layer for regulated capital markets, with a focus on Asia.

Strium does not operate as a general-purpose blockchain. The network prioritizes high-volume processing, low latency, and reliable settlement, three core requirements for institutional activity. The architecture is designed to support multiple asset classes, including tokenized securities such as U.S. and Japanese equities, RWA-linked instruments, and spot and derivatives markets.

The proof of concept already developed demonstrated stability under high-load scenarios, settlement efficiency, and compatibility with existing financial infrastructure. Its design enables interoperability with traditional trading, clearing, and post-trade systems, as well as with blockchain networks, without relying on native asset issuance or custody models.


Strium Will Feature Account Abstraction for Retail Users

The platform is positioned as core infrastructure for Asia’s on-chain securities market. It will offer 24/7 trading and near-instant settlement across jurisdictions within regulated environments. To expand beyond institutional markets, Strium will incorporate account abstraction, aiming to simplify operational management for retail users while maintaining compatibility with decentralized finance applications.

Strium’s adoption strategy will leverage the SBI Holdings ecosystem, which includes a user base of approximately 80 million across banking, financial, and investment services. This broad reach is expected to accelerate liquidity formation once the network becomes operational.


A Yen-Denominated Stablecoin and Testnet Ahead

The roadmap also includes the development of a yen-denominated stablecoin for on-chain settlement. The asset will be issued by Shinsei Trust & Banking and distributed through SBI VC Trade, with a planned launch in the second quarter of 2026. The stablecoin will serve as a regulated settlement instrument for domestic and cross-border operations.

Strium is also designed to support the participation of automated agents in market activities, with infrastructure prepared for direct interactions with on-chain liquidity. The next milestone will be the launch of a public testnet later in 2026, ahead of full production deployment
