New Blockchain Audit Tool Aims to Bring JPYC Stablecoin to Japanese Enterprises and Municipalities
Tokyo-based software developer Asteria Corporation (TSE: 3853) has partnered with blockchain engineering firm Angoya to launch "JPYC Explorer," a specialized audit-support tool for the Japanese yen-pegged stablecoin, JPYC.
Slated for release on April 1, 2026, the new platform targets a critical bottleneck in the institutional adoption of digital assets: the ability to conduct rigorous, compliant accounting audits on blockchain transactions.
While JPYC—issued by JPYC Inc. since October 2025—has garnered attention for facilitating fast, low-cost domestic and cross-border settlements, listed companies and local municipalities have hesitated to adopt it due to the technical complexities of on-chain auditing.
To resolve this, Asteria tapped into Angoya’s existing "Lensa" blockchain audit technology to co-develop JPYC Explorer. The enterprise-grade tool empowers audit firms and major corporations to operate their own self-managed "full nodes." By allowing entities to verify the existence and validity of transactions in-house, the system eliminates reliance on third-party APIs or external tools, placing the entire verification process firmly under internal control.
Crucially, the platform aligns with the Web3 audit guidelines published by the Japanese Institute of Certified Public Accountants (JICPA). By extracting data directly from a self-managed full node, JPYC Explorer satisfies the stringent reliability and internal control requirements demanded by institutional auditors. It features an intuitive interface designed to visualize complex blockchain data, significantly streamlining the auditing workflow.
Technical Specs and Pricing
At launch, JPYC Explorer will support both JPYC and the U.S. dollar-pegged USDC, with plans to add more stablecoins in the future. The software is compatible with the Avalanche, Ethereum, and Polygon blockchains, and offers flexible infrastructure deployment, supporting both cloud environments and on-premise physical servers.
Asteria has set the base pricing at 500,000 yen per month (excluding tax), which encompasses comprehensive training and support. Firms can also purchase an optional add-on starting at 50,000 yen per month per audited entity, which scales based on the volume of JPYC handled.
Strategic Implications and Industry Reaction
Deepening the strategic ties between the two developers, Angoya CEO Yuki Shichiku will concurrently step into an advisory role for Asteria’s stablecoin division upon the product's launch.
The initiative has drawn strong support from the stablecoin issuer itself. Noritaka Okabe, CEO of JPYC Inc., highlighted the software's potential to accelerate market penetration.
"Establishing an environment where companies and local governments can use JPYC with peace of mind is a vital step for stablecoin adoption," Okabe said in a statement. "Because JPYC Explorer allows audit firms and enterprises to verify transaction reality with their own hands, we recognize this as a major leap forward for the social implementation of JPYC. We will continue to work alongside Asteria to build the infrastructure necessary for the healthy proliferation of stablecoins."
