Shinhan Card, a subsidiary of Shinhan Financial Group, signed a memorandum of understanding with the Solana Foundation in Seoul on April 30, 2026, committing both parties to an advanced proof-of-concept (PoC) that tests stablecoin-based payments on the Solana testnet (the network's test environment, separate from its live mainnet). The agreement was signed by Kim Young-il, vice president at Shinhan Card, and Lu Yin, head of business development for the Asia-Pacific region at the Solana Foundation. No commercial product will launch from this phase. Both parties say a public rollout depends on regulatory approvals that have not yet been granted.

The PoC builds directly on work completed in 2025, when Shinhan Card validated six core blockchain projects alongside Korean technology firms Aton and BlockOdyssey and global partners including Solana, Fireblocks, Visa, and Mastercard. That first round spanned six validated use cases, including peer-to-peer payments, cross-border remittance, and a hybrid debit-credit card model in which a user's stablecoins are debited instantly for purchase transactions, while credit spending is secured by digital assets held as collateral. The new phase adds oracle integration (software that feeds real-world transaction data into smart contracts), stability testing for non-custodial wallets (wallets controlled solely by the user, with no third-party holding the keys), a monitoring framework for smart contract execution, payment flow scenarios between customers and merchants on the Solana testnet, and a hybrid model that combines legacy card infrastructure with on-chain settlement, a configuration that bridges traditional finance and decentralized systems in a single payment flow.

"We plan to rigorously verify the practical applicability of blockchain technology and aim to deliver secure payment services once regulatory conditions are met," a Shinhan Card spokesperson said. The Solana Foundation stated it would "prioritize regulatory compliance and customer protection" while combining what it called the reliability of traditional finance with the efficiency of decentralized systems.

The choice of Solana as the settlement layer reflects the network's current throughput figures. Post-Firedancer upgrade, Solana processes roughly 65,000 transactions per second on mainnet, with stress tests exceeding one million TPS. Monthly stablecoin transaction volume on the network reached approximately 650 billion dollars as of early 2026. Separately, outstanding stablecoin issuance on Solana grew from roughly 5 billion dollars in 2024 to approximately 15 billion dollars in 2025. One day before the MOU was signed, Meta announced it had quietly rolled out stablecoin payments via Solana and Polygon, adding independent weight to the network's case as enterprise-ready payment infrastructure.

South Korea's regulatory picture is unsettled but moving fast. The ruling Democratic Party proposed the Digital Asset Basic Act on April 8, 2026, less than four weeks before this MOU. The draft bill would require stablecoin issuers to hold reserves equal to at least 100 percent of their issuance, prohibit yield-bearing stablecoins entirely, and force foreign issuers such as Circle (which issues USDC) to establish a licensed local entity before their tokens can be legally used in Korea. A significant dispute remains unresolved: the Bank of Korea insists that only banks with at least 51 percent ownership should be permitted to issue won-pegged stablecoins, while the Financial Services Commission argues that restriction would choke innovation. That conflict stalled earlier legislation throughout 2025.

The Shinhan deal sits inside a broader Solana push into Korea. The Foundation has also signed agreements with Hanwha Asset Management for Solana-based exchange-traded products and with DB Securities, one of Korea's major brokerages. Solana Ventures and the Foundation have committed a combined 100 million dollars to a fund targeting Korean Web3 startups, focused primarily on gaming and decentralized finance. Lily Liu, president of the Solana Foundation, described Korea as "a key market for global crypto adoption, where regulatory clarity, institutional infrastructure, and world-class developer talent converge." The Foundation has also developed CONTRA, a Solana-native institutional privacy layer pitched specifically to Korean financial firms for use in security token offering and won-stablecoin integrations; it is named as part of Shinhan's planned integration toolkit, making it a relevant technical layer for institutional and developer audiences following this deal.

The regional consequences of this PoC extend well past East Asia. For South Asia, the model is directly relevant to cross-border remittance. India, Bangladesh, Pakistan, and Sri Lanka are among the world's largest recipients of remittances, funds routed through correspondent banking networks that typically charge 3 to 6.5 percent per transfer and take up to five days to settle. Stablecoin rails can complete the same settlement in roughly 60 seconds at under 1 percent cost. Shinhan's advanced PoC is designed to demonstrate that incumbent institutions can embed this infrastructure behind a familiar card interface, so that end users never need to understand or hold cryptocurrency directly. For Africa, where stablecoin remittance corridor volume grew 200 to 300 percent year-on-year in 2025 across Nigeria, Kenya, and Ghana, the same abstraction model is relevant to mobile money operators such as MTN MoMo and M-Pesa that are already integrating stablecoin rails into their existing apps.

Regulators in Nigeria, Kenya, and South Africa are each running active consultations on digital asset frameworks. South Korea's proposed rules on reserves, yield restrictions, and foreign exchange classification could serve as a working reference for those processes. How Seoul resolves the Bank of Korea versus FSC dispute over stablecoin issuance rights may carry particular weight for countries where central banks and securities regulators hold competing jurisdictional claims over the same instruments. India faces a directly parallel dynamic: the Reserve Bank of India and the Securities and Exchange Board of India hold overlapping authority over digital assets, even as India advances its own central bank digital currency program and actively explores stablecoin policy, meaning South Korea's regulatory resolution carries relevance for South Asian policymakers as well as African ones.
