— Evaluating in-store operational processes, from crypto-asset transfers and receipt confirmation to conversion into Japanese yen and bank account deposits —
UPCX-Platforms Pte. Ltd. (Director: Makoto Nakano; hereinafter “UPCX”), together with BitTrade Inc. (President and Representative Director: Lei Guan; hereinafter “BitTrade”), conducted a technical proof of concept (hereinafter the “PoC”) involving in-store checkout operations using the UPC crypto asset and its conversion into Japanese yen on Wednesday, October 21, 2026, with the cooperation of Sushi Yoneshima in Fukuoka City, Japan.
UPC is the native token of the UPCX blockchain. The PoC used UPC (ERC-20) issued on Ethereum.
The PoC evaluated the end-to-end operational process, including the restaurant’s presentation of the required UPC amount at checkout, participants’ transfers of UPC, confirmation of receipt by the restaurant, conversion into Japanese yen through BitTrade’s brokerage service, and deposit into the restaurant’s bank account.
Based on feedback from the restaurant, the PoC also identified two areas for improvement: presenting the amount due more quickly at checkout and reducing the restaurant’s operational burden associated with conversion into Japanese yen and withdrawal procedures.
Background and Objectives
For restaurants and other merchants, the timing of receipt of sales proceeds is an important factor directly linked to purchases of ingredients and day-to-day working capital management.
With existing cashless payment services, including credit card payments, settlement cycles vary depending on the service and contractual terms, and there may be a period between a sale and the deposit of the proceeds into a bank account.
Restaurants, in particular, incur ongoing expenses such as purchases of ingredients and personnel costs.
They therefore need to manage their cash flow with the time gap between a completed sale and receipt of funds in mind.
Combining blockchain-based asset transfers with conversion into Japanese yen may offer a way to make the process of receiving funds more efficient for merchants.
However, incorporating such processes into actual store operations requires several tasks to be handled smoothly, including checking transfer destinations, confirming receipt, managing price fluctuations, and converting assets into Japanese yen and withdrawing the funds.
Against this background, UPCX and BitTrade conducted the PoC with the cooperation of a physical restaurant to evaluate the operational process from crypto-asset transfers and receipt confirmation to conversion into Japanese yen and bank account deposits, and to assess its feasibility and identify operational challenges.

Comment from the Participating Restaurant, Sushi Yoneshima
“I found it particularly appealing that the crypto assets we received were converted into Japanese yen and deposited into our bank account on the same day. With credit card payments, there is a period of time before sales proceeds are deposited. In this PoC, being able to access the funds on the same day made me feel that it could make day-to-day cash flow management, including purchases of ingredients, easier. On the other hand, I felt that it would be difficult to leave the task of converting the received crypto assets into yen to staff on site. Being able to communicate the amount due quickly is also important, so I believe improvements in usability, such as linking the cash register with a payment terminal, will be necessary. We also welcome many guests from overseas, and I look forward to being able to offer new payment options to both domestic and international customers in the future.”
Future Developments | Reducing Merchants’ Operational Burden and Building Next-Generation Payment Infrastructure
UPCX will apply the insights gained regarding checkout usability and merchants’ operational burden to development and operational design for the implementation of stablecoins on the UPCX mainnet. With both domestic and international use in mind, UPCX aims to create a payment environment that is easy for merchants to use.
