Shinhan Card, one of South Korea’s largest credit card issuers, has signed a memorandum of understanding with the Solana Foundation to advance the testing of stablecoin payments and explore non-custodial wallet integration. The partnership builds on an earlier proof of concept completed in early April and aims to assess the commercial viability of blockchain-based payments for both merchants and consumers.
Partnership expands beyond initial pilot
Following a joint pilot project that concluded at the beginning of April, Shinhan Card announced on Thursday that it will conduct a more advanced proof of concept with the Solana Foundation. The expanded partnership will explore the feasibility of stablecoin payments in real-world retail environments, as well as the development of a hybrid financial model that combines traditional finance infrastructure with decentralized finance capabilities.

Shinhan Card is South Korea’s second-largest credit card issuer by market share, holding 16.9% as of March, according to KED Global. The company was recently overtaken by Samsung Card, which holds a 17.02% share for the top spot. The move signals that major traditional financial institutions in South Korea are actively investigating blockchain technology to improve payment efficiency and customer experience.
DeFi services and smart contract exploration
Shinhan Card stated that the ultimate goal of the partnership is to develop its own DeFi-linked services. These services would implement blockchain oracles — technology used to connect offchain data with onchain environments — and test the execution stability of smart contracts, which are self-executing digital agreements written in code.
During the initial proof of concept completed on April 9, Shinhan Card and the Solana Foundation tested six key areas: blockchain-based peer-to-peer payments, digital asset integrated payment infrastructure, stablecoin-based check and credit hybrid products, stablecoin-based cross-border remittances and settlement, stablecoin payments, and IC chip-based card payment services for crypto wallets. Shinhan described the earlier PoC as a potential blueprint for bridging fiat-based payment systems with the digital asset ecosystem.
Industry context and broader adoption trends
Shinhan Card is not alone in exploring stablecoin-based payment solutions. Major financial infrastructure providers including Visa, Mastercard, and BC Card have been testing similar technologies. Visa, for example, launched USD Coin settlement services for select US-based financial institutions on the Solana blockchain in December 2025. These developments indicate a growing institutional interest in stablecoins as a tool for improving payment settlement speed and reducing costs.
For South Korean consumers and merchants, the partnership could eventually lead to faster, cheaper cross-border payments and more flexible payment options that combine traditional credit infrastructure with digital asset capabilities. However, the technology remains in the testing phase, and widespread commercial deployment is not yet confirmed.
Conclusion
Shinhan Card’s partnership with the Solana Foundation represents a significant step in the integration of blockchain technology into mainstream financial services in South Korea. By testing stablecoin payments and exploring DeFi-based services, the company is positioning itself to potentially offer next-generation payment solutions that bridge the gap between traditional finance and the digital asset ecosystem. The outcomes of the advanced proof of concept will be closely watched by industry observers and competitors alike.
