WEB3 Service

The era of Web3 has arrived, and its market size is expanding rapidly. However, while this growth, many companies face technical hurdles, cryptocurrency stability, and challenges in building systems that support sustainable growth. In particular, the problem of cryptocurrencies rapidly depreciating in value after listing is a major risk for companies.

To solve these challenges, it is essential to go beyond simply introducing new technologies and to have a solid foundation and innovation. We, Shirushi Co., Ltd., are committed to providing Web3 technology and services to overcome these challenges.

We use blockchain technology to build a virtual currency mechanism that can provide stable value and a system that can grow sustainably. In addition, we provide innovative solutions to support the future of Web3, creating an environment where companies and individuals can use it with peace of mind.

Web3 has the potential to go beyond mere technological evolution and create a freer and more equitable economic zone. We will continue to provide services that combine reliability and innovation to unlock the true potential of Web3 to unlock this future.

The SISC (Shirushi Coin) developed by our company is a unique crypto asset designed and developed in-house from scratch, and is a product that symbolizes our technological prowess and innovation.

In the years since its listing, SISC has grown to a market capitalization of over 40 billion yen (as of November 30, 2025), attracting high interest in both domestic and international markets.

In addition, with the aim of stabilizing the value of SISCs over the medium to long term, we continue to make efforts to contribute to the formation of a sound market, such as improving the trading environment and improving liquidity. This also allows us to focus on countermeasures against “post-listing value decline”, which is one of the issues in crypto assets.

We have built a system that allows us to respond consistently within the company, from coin development to listing support and the establishment of a post-listing management system. Through this integrated operation, we can provide high-quality and efficient services, and our strength is our ability to respond quickly and flexibly.

We are not just a technology provider, but also a foundation that supports the Web3 market, contributing to the healthy growth and development of the entire industry.

In the future, we will develop diversified new services such as white-label services and consulting businesses to support companies entering Web3 more strongly. This will help many companies to make full use of the potential of Web3 and build sustainable business models.

Sign Co., Ltd. will always be at the forefront of challenges to shape the future of Web3. Through blockchain, we aim to become a bridge connecting the future of individuals, companies, and society, and continue to lead the mining industry and the Web3 market.
