HashPort, a Japanese Web3 firm, is set to launch a fee-free stablecoin payment service on January 28. The service, which leverages blockchain technology, aims to eliminate transaction fees for merchants, a common cost in traditional cashless systems. Users can make payments by scanning a merchant's QR code via HashPort's wallet app, while merchants can access the system without any registration or usage fees. Initially, the service will target foreign tourists with stablecoins, facilitating payments at restaurants and similar venues.
