Datachain Launches "On-chain Finance Technology Consulting," Providing End-to-End Technical Support for On-chain Finance Services from Concept to Commercial Launch

Datachain, Inc. (CEO: Tetsushi Hisata; hereinafter “Datachain”), which is engaged in building next-generation financial and payment infrastructure leveraging blockchain technology, is pleased to announce the launch of "On-chain Finance Technology Consulting" (the "Service"). The Service supports financial institutions and businesses on the technology side of the blockchain domain, end to end, taking their on-chain finance services from the idea stage all the way to commercial launch.

Background

In Japan, the first yen-denominated stablecoin compliant with the Payment Services Act was issued in October 2025. Since the start of 2026, banks have moved to commercialize tokenized deposits and Japan's three megabanks have been preparing to issue stablecoins. On-chain finance is shifting from the study phase to the implementation phase.

Turning a concept into a working system, however, requires a series of advanced technical decisions unique to blockchain: whether blockchain is the right tool in the first place, the choice between tokenized deposits and stablecoins, chain selection, interoperability across different blockchains, privacy protection for transaction data, key management, and integration with existing systems. In supporting financial institutions to date, we have seen many cases where the difficulty of these technical decisions became a barrier to moving a concept into implementation and commercial launch.

To address these challenges, Datachain has systematized the track record and expertise it has built through research and development since its founding in 2018 and through its own on-chain finance businesses, and is now offering them as the Service.

Key Features of the Service

The Service is a consulting service that provides technical support, from concept to commercial launch, to financial institutions and businesses exploring on-chain finance services built on stablecoins, tokenized deposits, digital securities and similar instruments.

‍

1. End-to-end support from concept to commercial launch

We welcome inquiries even before an idea has taken shape, and we support clients end to end: concept exploration from a technical perspective, requirements definition, design and development, validation, and technical support toward commercial launch. We can also start from whichever stage a client needs, such as requirements definition or validation alone.

‍

2. Technical strength from building our own infrastructure

Since its founding in 2018, Datachain has conducted research and development centered on interoperability technology between blockchains, releasing technologies such as YUI (a Hyperledger Labs project) and LCP as open source. This work has been productized as the enterprise wallet "Datachain Wallet," the on-chain privacy infrastructure "KuraPrivacy," and cross-chain infrastructure. As builders who have developed this infrastructure ourselves, we identify early what can and cannot be done and design for what is achievable, helping clients avoid rework. We provide our own products where needed, but our support does not presuppose their adoption.

‍

3. Proven track record with financial institutions and a specialist team

Datachain has supported financial institutions' on-chain finance initiatives on the technology side, including its technical advisory for MUFG Bank. Members with hands-on financial experience at global financial institutions and major consulting firms work as one team with engineers who develop blockchain infrastructure.

‍

Scope of Support

Centered on the blockchain domain, Datachain supports clients from concept to commercial launch in the following five steps. Clients do not need to engage us for every step, we also support individual steps as needed.

‍

1. Concept exploration from a technical perspective: We clarify whether blockchain is needed, the choice between tokenized deposits and stablecoins, the chain model, and related questions.
2. Requirements definition: We specify issuance, redemption and transfer flows, privacy requirements, key management methods, and more.
3. Design and development: We design and build the solution, including chain selection, smart contract design, and the architecture for integrating with existing systems.
4. Validation: We design and evaluate PoCs, validate business operations such as DvP settlement, and verify performance and cost.
5. Commercial launch: We provide technical support for the move to production and advise on building operations and monitoring capabilities.

‍

Future Outlook

As a technology company building the infrastructure for the era of on-chain finance, Datachain will continue to support financial institutions and businesses through the Service until their concepts reach commercial launch. By combining the technical strength built through research, development and products with the expertise gained from working with financial institutions, Datachain will accelerate the real-world adoption of on-chain finance.
