Japan’s SBI Holdings has restructured a wholly owned subsidiary into a dedicated SBI Digital Practice Canton unit, positioning the group’s institutional blockchain operations across a multichain stack that now runs from XRP Ledger to Solana, Ondo Finance, and a permissioned institutional network sitting on top of more than $6 trillion in represented assets.
What SBI Digital Practice Brings to Canton
The subsidiary, formerly SBI Security Solutions, adopted its new name on 22 June and was formally announced on 28 July. Representative director Ryo Shimotsu leads the Roppongi-based operation, which SBI retains in full ownership.
SBI Digital Practice will plan, develop, and operate financial infrastructure and applications for institutions on the Canton Network, covering implementation support, regulatory compliance, and cross-border transaction systems. SBI has held a Super Validator role on Canton, meaning the subsidiary already carries network-level responsibility for transaction approval and management.
Canton itself runs on Daml, Digital Asset’s smart-contract language, and is designed as a network of networks: independent financial applications can interoperate with one another while preserving the privacy, permissioning, and governance controls that regulated markets require. Over 600 institutions are connected, including Goldman Sachs, BNP Paribas, Franklin Templeton, Broadridge, and Euroclear.
SBI’s involvement predates the restructuring. When Canton launched, Fernando Vazquez Cao, then chief executive of SBI Digital Asset Holdings, was among the quoted participants welcoming the network’s model of interconnected, trusted financial infrastructure.
DTCC, ComposerX, and the Treasury Tokenisation Link
The most structurally consequential piece of Canton’s expansion is its connection to U.S. Treasury tokenisation. In December 2025, DTCC and Digital Asset announced plans to tokenise a subset of U.S. Treasury securities custodied at the Depository Trust Company (DTC) on Canton. DTCC received a No-Action Letter from the Securities and Exchange Commission (SEC) to implement the service, and will deploy its ComposerX platform suite to execute the tokenisation. A controlled production launch was targeted for the first half of 2026.
A July transaction through Tradeweb subsequently paired an on-chain U.S. Treasury with USDCx and settled through Canton, giving the pathway a live proof point. For SBI Digital Practice, the implication is a direct channel into U.S. fixed-income infrastructure from a Tokyo-headquartered operator.
SBI is also investing further inside the Canton ecosystem. According to Fintech Observer, SBI Holdings is leading a private investment round for New York-based Temple Digital Group, framed as a vertical integration move within Canton ahead of a 2026 regulatory shift.
A Multichain Stack Still Growing
Canton is only one layer in a broader expansion that SBI has been assembling across 2025. On Solana, SBI Global Asset Management partnered with DigiFT to launch the JX token on 14 July: the first on-chain listed-equity strategy from a Japanese asset manager, distributed through DigiFT’s regulated infrastructure to eligible institutional and accredited investors. Returns are reflected through the underlying growth strategy rather than direct dividend distributions.
The timing fits a wider market shift. According to Yahoo Finance’s reporting on the JX launch, the value of tokenised real-world assets on public blockchains grew from $5.9 billion to $21.9 billion globally across 2025, with the expansion moving beyond cash-like instruments into actively managed strategies.
SBI’s agreement with Ondo Finance adds another rail: tokenised Japanese equities issued by Ondo Global Markets (BVI) Limited, with the yen-backed JPYSC stablecoin used for settlement and collateral. On 7 August, SBI Digital Practice and Nodeinfra announced plans to build a stablecoin cross-border payment network linking Japan and Korea. And SBI VC Trade has stated an intent to list Canton Coin in Japan, targeting 25 March 2026.
The Chainlink dimension was formalised on 24 August 2025, when SBI Group and Chainlink announced a strategic partnership to accelerate blockchain and digital asset adoption, with Japan as the initial launch market. SBI Group carries over $200 billion in total assets, giving these partnerships institutional weight rather than venture-scale experimentation.
The Ripple relationship runs in parallel, not competition. SBI Ripple Asia, founded in 2016, continues developing XRP Ledger services including a token issuance platform calibrated to Japanese regulatory requirements. Payments, stablecoins, and domestic token issuance stay on Ripple’s rails; cross-border securities, privacy-sensitive institutional settlement, and U.S. Treasury tokenisation now run through Canton.
Canton Coin’s targeted listing date of 25 March 2026 is the next hard catalyst on the calendar.
