Japan's SBI Deepens Solana Ties in Institutional DeFi Growth
  • SBI and Solana plan a regulated platform for stablecoins, tokenized assets, and settlement.
  • JPYSC and tokenized bonds could connect Japan’s financial system with global liquidity.
  • The venture builds on R3’s network of more than $10 billion in regulated on-chain assets.

SBI Holdings is expanding its blockchain strategy through a new alliance with the Solana Foundation focused on digital finance in Japan. The agreement centers on stablecoins, tokenized assets, cross-border settlement, and public blockchain distribution.

Under the arrangement, the foundation will join SBI R3 Japan, which is expected to adopt the name SBI Solana Global. SBI Holdings and Sumitomo Mitsui Financial Group will remain involved, although ownership terms and financial details were not disclosed.

Stablecoins and Tokenized Assets Anchor the New Venture

The planned venture will support yen-linked stablecoins, including JPYSC, alongside tokenized corporate bonds, commercial paper, investment funds, and real estate. Its remit also includes payment infrastructure for AI agent transactions and institutional on-chain finance services.

Rather than serving only as a technology provider, the company plans to connect issuance, distribution, settlement, and compliance within one framework. That structure links Japan’s regulated financial sector with Solana’s public network and liquidity.

This strategy also aligns with Japan’s evolving digital asset regulations. In June 2023, the country introduced rules governing electronic payment instruments, thereby creating a formal legal category for certain fiat-backed stablecoins. Under the framework, eligible issuers include banks, trust companies, and licensed fund-transfer businesses. 

At the same time, intermediaries must register, apply customer-protection measures, and meet anti-money-laundering standards. Travel-rule requirements also compel providers to transmit originator and beneficiary information during transfers.

Consequently, these obligations are likely to influence wallet design, cross-border settlement, investor access, and compliance controls for products launched through SBI Solana Global.

R3 Integration Expands SBI’s Institutional Blockchain Reach

Beyond its Solana partnership, SBI Holdings is already developing JPYSC with Startale Group as a trust-based yen electronic payment instrument. Shinsei Trust & Banking has been designated as the issuer, further strengthening the project’s regulated structure.

The group also gained regulated distribution experience after SBI VC Trade registered as an electronic payment instruments service provider in March 2025. It later began offering USDC trading.

The alliance also follows R3’s May 2025 alliance with the Solana Foundation. That project connected Corda’s permissioned infrastructure with Solana’s public blockchain while retaining identity, privacy, and compliance controls.

R3 said its ecosystem represented more than $10 billion in regulated on-chain assets at the time. However, the latest announcement remains a strategic framework rather than a product launch. It provided no timetable for JPYSC issuance, initial assets, settlement partners, or governance arrangements.
