Shinhan Card, South Korea’s largest card issuer with 28 million cardholders, has signed a memorandum of understanding with the Solana Foundation. The deal covers stablecoin payment technology and joint development of next-generation payment infrastructure.

This isn’t a small partnership. It’s one of the largest TradFi-to-crypto collaborations announced in Asia this year, and it puts Solana at the center of how a major Korean financial institution thinks about the future of payments.
What’s Actually Being Built By Solana & Shinhan
Shinhan Card and Solana already completed a preliminary proof-of-concept last year. This new MoU expands that work into an advanced PoC on the Solana testnet. The two teams are building real payment scenarios between customers and merchants while testing the network’s technical stability under conditions closer to actual use.
A big part of the work focuses on non-custodial online wallets. Users keep full control over their assets without relying on a third party. That matters because it changes the trust model entirely. Traditional card payments depend on the bank or processor holding everything.
Non-custodial wallets put that responsibility on the user. Shinhan Card wants to figure out how to make that work safely at the scale of 28 million customers.
The Hybrid TradFi-DeFi Model
The partnership goes beyond payments. Shinhan Card is also developing a hybrid financial model that combines traditional finance infrastructure with DeFi.
The company plans to use oracle technology to feed real-world transaction data into blockchain networks securely. From there, the goal is to build its own DeFi service environment.
This is where the work gets interesting. Smart contract execution stability has to be tested. A monitoring framework for next-generation financial models has to be established. None of this is theoretical anymore.
A major card issuer is actually doing the engineering work to figure out how DeFi components can plug into existing financial infrastructure without breaking either side.
What’s in There For 28 Million Cardholders
The size of Shinhan Card’s user base is what makes this partnership different from most stablecoin pilot programs.
28 million cardholders is a meaningful chunk of South Korea’s population. If even a fraction of those users start making stablecoin payments through Solana-based infrastructure, the volume implications are significant.
The phrasing in the announcement matters too. Shinhan Card says it will continue strengthening its Web3 capabilities and “review concrete plans for launching related services in line with future regulatory requirements.” The company is preparing to launch services, not just experiment with technology.
What Both Sides Are Saying
A Shinhan Card official said the partnership will help validate the practical applicability of blockchain technologies. The goal is to deliver secure and convenient payment services by combining the company’s expertise with Solana’s infrastructure once regulatory conditions are in place.
A Solana Foundation official said the collaboration aims to overcome the limitations of existing financial services. The partnership combines the trust and reliability of traditional finance with the efficiency of DeFi while prioritizing regulatory compliance and customer protection.
The regulatory framing on both sides is consistent. This isn’t a partnership trying to bypass regulation. It’s a partnership trying to build something that can launch when regulation catches up.
Final Thoughts
Shinhan Card is bringing 28 million Korean cardholders closer to stablecoin payments on Solana. The MoU covers payment scenarios, non-custodial wallets, oracle integration, and hybrid TradFi-DeFi models.
The work is technical and the timeline depends on regulation, but the scale is real. When Korea’s largest card issuer starts engineering its payment future on Solana, that’s not a pilot. That’s preparation for something concrete.
