OnePay and Shinhan Card Launch Stablecoin Payment Initiatives

Major financial entities in the U.S. and South Korea are integrating stablecoin technology into consumer payment systems to reduce costs and increase settlement speeds. In late April, OnePay partnered with Tempo, a payments-focused Layer-1 blockchain incubated by Stripe and Paradigm, to launch stablecoin-based payouts and instant account funding. To support the network, OnePay is also launching a validator on the Tempo blockchain to ensure infrastructure stability for its millions of American users.

Simultaneously, South Korea's second-largest credit card issuer, Shinhan Card, signed a memorandum of understanding with the Solana Foundation to explore decentralized finance (DeFi) infrastructure. Following a joint pilot project in early April, the two organizations are conducting a proof-of-concept on the Solana testnet to evaluate the commercial feasibility of stablecoin payments for merchants and customers. Shinhan Card intends to utilize blockchain oracles to connect off-chain and on-chain data, though the company noted that full implementation remains contingent on future regulatory compliance.
