Shinoken Group and JAPAN POST BANK Start Collaborative Digital Currency (JAPAN POST BANK's Tokenized Deposits) PoC!

DeCurret DCP Inc. (Head Office: Chiyoda-ku, Tokyo; Representative Director, Chairman and President, CEO : Satoshi Murabayashi; hereinafter “the Company”) announces that it has signed a basic agreement for collaboration with Shinoken Group Co., Ltd. (Tokyo HQ : Minato-ku, Tokyo; President and Representative Director: Takashi Tamaki; hereinafter referred to as “Shinoken Group”) and JAPAN POST BANK Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President & CEO, Representative Executive Officer, Member of the Board of Directors : Takayuki Kasama; hereinafter referred to as “JAPAN POST BANK”) have entered into a basic agreement for collaboration to utilize JAPAN POST BANK's tokenized deposits (hereinafter referred to as “Tokenized Deposits”).

１.Tokenized deposits
Tokenized deposits are bank deposits converted into tokens. They offer the same security and reliability as traditional bank deposits while leveraging technologies like blockchain to provide convenient digital access. By linking transaction records and contract terms, they enable diverse services such as controlling and automating fund flows. While proof-of-concept (PoC) trials for various industries are currently underway, the Shinoken Group is the first* to conduct a PoC utilizing tokenized deposits within the real estate industry.

2.Proof-of-Concept and Schedule
This proof-of-concept (PoC) will verify the automation and efficiency of payments utilizing tokenized deposits, using the monthly rent payments in Shinoken Group's rental management as a use case. We aim to complete this by the end of December 2025. Based on the results, we will proceed with preparations for full-scale implementation starting in 2026.

3.Future Service Development
Using this tokenized deposit, which enables instant settlement, allows for greater flexibility and convenience in daily life. For example, payments that previously had fixed due dates—such as rent, gas, and electricity bills—can now be freely set within a certain range according to the customer's convenience.
Furthermore, the Shinoken Group is considering rewarding “Shinoken Coins” (the Group's proprietary points) based on lifestyle history, such as tenancy duration, payment history, and tenant referrals. The goal is to enable seamless use of accumulated Shinoken Coins across services provided by the Shinoken Group, such as searching for your next residence.

4.Our Future Outlook
Through collaboration with the Shinoken Group and JAPAN POST BANK, we will enter into the real estate industry's settlement services for the first time. By working together to solve industry challenges and create new value, we will contribute to the overall development of the real estate sector through tokenized deposits. Moving forward, we will continue to work with various companies to create new economic ecosystems using tokenized deposits.
