WEA Secures Two Japanese Patents: Building Trusted Infrastructure for Stablecoin Payments

As global stablecoin regulations continue to mature, stablecoin payments are accelerating from concept to large-scale commercial adoption. Recently, WEA JAPAN Co., Ltd. was granted two Japanese patents focused on the core infrastructure of stablecoin payments — a trusted exchange rate verification mechanism and a payment refund mechanism.

The two patents are:

• “Foreign Exchange Rate Determination System, Foreign Exchange Rate Determination Method, Settlement System, and Settlement Method” https://www.j-platpat.inpit.go.jp/c1801/PU/JP-7811423/15/en
• “Refund System and Refund Method” https://www.j-platpat.inpit.go.jp/c1801/PU/JP-7857640/15/en

PS: Details of these patents have also been updated on the WEA website.

The breakthroughs represented by these two patents mark an important step forward for WEA in advancing compliance standards, commercial execution standards, and Web3 payment service standards. By addressing critical stages before and after payment execution, they provide trusted, reliable, and auditable technical solutions that establish a foundation for the compliant adoption of stablecoins in real-world commercial scenarios.

The Real Challenge of Stablecoin Payments

In the past, the industry focused primarily on blockchain performance and wallet user experience. However, as stablecoins move into real-world scenarios such as airport retail, dining, e-commerce, and cross-border payments, the priorities of merchants and enterprises have shifted:

• Are exchange rate data trustworthy and verifiable?
• Are settlement records traceable and auditable?
• Can refunds, order cancellations, or partial returns be processed quickly and efficiently?
• Does the overall process meet regulatory compliance requirements?

These questions directly determine whether stablecoins can achieve mainstream commercial adoption. Payments themselves are only the surface layer; the trusted infrastructure behind them is what truly matters.

The Core Value of Trusted Exchange Rate and Refund Mechanisms

In practice, a stablecoin payment often involves exchange rate conversion, cross-currency settlement, and subsequent fund processing. Traditional payment systems already have mature standards in place, while the stablecoin sector still needs to address both technical and compliance gaps.

WEA’s two patents are designed specifically to address these challenges. The trusted exchange rate verification mechanism ensures the authenticity and verifiability of exchange rate data throughout the payment process, while the refund system optimizes post-transaction fund returns, improving merchant operational efficiency and consumer protection.

These technological achievements represent more than innovation. More importantly, they help establish compliance-oriented technical standards and commercial execution standards for the industry, supporting the evolution of Web3 payments toward greater maturity, trustworthiness, and reliability.

From Patents to Real-World Applications

The value of technology lies in its practical application. WEA has been actively advancing stablecoin payment initiatives in Japan, including participation in the Haneda Airport stablecoin payment pilot and the development of the StarPay-X ecosystem. These projects allow us to validate technology in real-world environments while gaining a deeper understanding of the balance between user experience, merchant operations, settlement efficiency, and regulatory requirements.

Looking Ahead

In 2026, Japan’s Financial Services Agency (FSA) implemented a new stablecoin regulatory framework that brings foreign-issued stablecoins into the electronic payment instrument framework, creating an important pathway for the standardized development of the market.

WEA will continue investing in blockchain payments, cryptographic security, privacy-preserving computing, trusted settlement systems, and digital commerce infrastructure. At the same time, we will work alongside payment institutions and ecosystem partners to further promote the adoption of stablecoin payments. We will also continue strengthening our core technologies and intellectual property portfolio.

The future of stablecoin payments is not simply about bringing assets on-chain. It is about enabling digital assets to truly serve real-world commerce. Supporting this future requires a secure, trusted, verifiable, and sustainable infrastructure network.
