-------------【 Job Description】-------------

■About the Company's Initiatives

On September 5, 2024, the company announced a project to build a cross-border remittance infrastructure in collaboration with international organizations. This initiative aims to achieve "fast, cheap, and convenient" international money transfers by utilizing stablecoins, which are digital currencies pegged to the value of fiat currency.

Since its founding in 2018, the company has consistently pursued R&D in technology and business opportunities. Their goal is to create a "de facto infrastructure" as a "Japan-born" "global x deep tech" leader.

While the company aims to become a decacorn (a startup with a corporate value of over $10 billion), it's often stated that achieving this goal requires "winning with global x deep tech."

The aforementioned cross-border remittance infrastructure project is a significant first step toward this ambition. Currently, due to Japan's proactive legal framework in this area, the company has an advantage in driving the project. However, given the vastness of the market, global competition is expected to intensify in the future.

In this environment, to spearhead the creation of a "de facto infrastructure" as a "Japan-born" "global x deep tech" entity, the company is rapidly expanding its recruitment, primarily focusing on personnel for its development team.

■Why the Company Can Achieve This

・The company has already begun to develop an international remittance infrastructure using stable coins in cooperation with international organizations that connect financial institutions around the world.

・Japan is leading the world in terms of legislation, with Japan becoming the first developed country to enact legislation on blockchain stablecoins in June 2023. This is important for major companies to use stablecoin.
