šØ SBI Holdings and Startale Labs unveil "Strium" as hybrid blockchain trading platform for tokenized securities and RWA in Asia šØ
Japanese financial giant SBI Holdings and blockchain infrastructure firm Startale Labs have branded their joint-venture tokenized trading platform as "Strium," positioning it as a "global capital markets infrastructure" and the "foundational exchange layer for Asia's onchain securities markets" rather than merely a trading venue. Originally announced in August 2025, Strium will provide 24/7 trading and settlement of tokenized securities and real-world assets (RWA), including both spot and derivatives, targeting institutional, professional, and retail traders. Startale CEO Sota Watanabe confirmed the platform will operate a hybrid Layer 1 blockchain modelāpermissioned participation for regulated institutions alongside permissionless access for professional and retail participantsāallowing compliant participation while enabling broader onchain liquidity and seamless value flow between Strium and traditional financial infrastructure.
š Key points
š¹ Brand and positioning: SBI and Startale branded the joint-venture platform as "Strium," positioning it as a global capital markets infrastructure for Asia's onchain securities markets rather than a standalone trading venue; the partners aim to establish Strium as the foundational exchange layer for tokenized assets in the Asia-Pacific region.
š¹ 24/7 trading and settlement: Strium will enable round-the-clock trading and settlement of tokenized securities and real-world assets, including both spot and derivatives products; the platform removes traditional market hour constraints and T+2 settlement cycles, offering institutional and retail participants continuous access to onchain markets.
š¹ Hybrid blockchain architecture: Startale CEO Sota Watanabe confirmed Strium will operate a hybrid Layer 1 blockchaināpermissioned participation for regulated financial institutions to satisfy compliance requirements, alongside permissionless access for professional and retail participants to enable broader liquidity and onchain activity across different ecosystems.
š¹ Multi-participant targeting: Strium aims to serve institutional investors, professional traders, and retail participants on a single platform; the hybrid architecture allows regulated banks and asset managers to participate under permissioned frameworks while opening onchain access to broader market segments.
š¹ Startale and Sony pedigree: Startale Labs founder created the Japanese blockchain Astar Network and co-developed Sony's Soneium blockchain, bringing Layer 1 development expertise and institutional partnerships; SBI Holdings operates Japan's largest online brokerage and has extensive financial infrastructure and regulatory relationships across Asia.
š Why it matters
š¹ Asia's tokenization race: Strium positions Japan as a challenger to Singapore and Hong Kong in the race to dominate Asia-Pacific tokenized securities infrastructure; while Singapore's Project Guardian and Hong Kong's tokenization pilots have attracted global banks, Strium offers a dedicated Layer 1 blockchain and comprehensive trading platform with SBI's regional distribution and regulatory relationships.
š¹ Hybrid model precedent: The permissioned-permissionless hybrid architecture attempts to solve a core tension in tokenized securitiesāregulated institutions require compliance frameworks and KYC/AML controls, while onchain markets demand open access and composability; if Strium successfully bridges these worlds, it could become the template for other jurisdictions struggling to balance regulation with decentralization.
š¹ 24/7 settlement disruption: Continuous trading and settlement removes the geographic and temporal constraints that have historically concentrated liquidity in New York, London, and Tokyo during specific market hours; if Strium gains traction, Asian investors could trade US equities, European bonds, and RWA around the clock, fragmenting liquidity pools and forcing legacy exchanges to extend operating hours or risk losing market share.
š¹ Institutional-retail convergence: By targeting institutional, professional, and retail participants on a single platform, Strium collapses the traditional segmentation between wholesale capital markets and retail brokerage; this convergence could democratize access to previously institutional-only products like private credit, infrastructure debt, and pre-IPO equity, but also raises questions about investor protection and market manipulation in 24/7 permissionless environments.
šÆ Bottom line: Strium is positioning itself as Asia's answer to fragmented tokenization pilots by offering a purpose-built Layer 1 blockchain with 24/7 trading, hybrid permissioned-permissionless access, and SBI's institutional distribution across Japan and the broader Asia-Pacific region. If the platform successfully bridges regulated financial institutions with open onchain markets, it could establish a new template for tokenized securities infrastructure that balances compliance with composability. However, Strium faces fierce competition from Singapore and Hong Kong, and the hybrid model remains unproven at scaleāany failure to deliver seamless interoperability between permissioned and permissionless participants could fragment liquidity and undermine the platform's value proposition.
