South Korea's Dunamu, the company behind the country's dominant crypto exchange Upbit, announced a formal partnership with Visa on Thursday to co-develop payment and remittance services built on stablecoin infrastructure and artificial intelligence. The two companies unveiled their joint roadmap at Visa's Global Market Support Center in San Francisco on August 27, with Dunamu CEO Oh Kyung-seok and Visa Global President Oliver Jenkyn both present for the occasion.

The partnership covers four areas: stablecoin-based payment and remittance in major markets, integration of Dunamu's GIWA blockchain with Visa's global payments network, exploration of business models around OUSD (a stablecoin issued by the Open Standard consortium, of which Visa is a founding member), and AI-powered payment services including what Visa calls "agentic commerce," where AI systems complete purchases autonomously on a user's behalf. Development will proceed in phases guided by four stated principles: stability, transparency, interoperability, and regulatory compliance.

"AI, stablecoins and tokenization are key trends that will reshape how finance and commerce operate," Oh said in remarks cited by the Korea Herald.

What GIWA Actually Is

GIWA is an Ethereum Layer 2 network built by Dunamu in partnership with the Optimism Foundation, using the OP Stack framework. Dunamu registered the GIWA trademark in 2025 and formally unveiled the chain at Consensus Miami in May 2026. Its testnet has processed close to 100 million transactions. Two features distinguish it from generic Layer 2 deployments: Dojang, an on-chain verification and notarization system, and Bojagi, a privacy layer designed specifically for financial institutions. In this publication's analytical reading, those features function as compliance and identity infrastructure aimed at banks and regulated fintechs, which makes the Visa partnership a natural fit. That characterization is interpretive rather than a formal product designation from either company.

Visa, for its part, is not new to stablecoin settlement. The company was the first payment network to settle a USDC transaction, doing so in March 2020, and now runs a stablecoin settlement program across nine blockchains: Ethereum, Solana, Avalanche, Stellar, Base, Polygon, Canton Network, Arc, and Tempo. That program reached a $7 billion annualized run rate in March 2026, up 50 percent quarter over quarter. In July 2026, Visa launched the Visa Stablecoin Platform, an umbrella product letting banks and fintechs mint, move, and manage stablecoins inside existing Visa workflows. OUSD, the same stablecoin Dunamu is exploring for this partnership, serves as that platform's strategic anchor alongside USDC and USDG.

Visa's agentic commerce ambitions extend further than most coverage of this deal has noted. At its Payments Forum in June 2026, Visa unveiled three supporting technologies: Agent Score (a trust-rating framework for AI agents making payments), Agentic Registry (a directory of verified AI agents authorized to transact), and Large Transaction Model (an AI system for flagging anomalous agentic purchases). These tools form the infrastructure backbone for any AI-driven payment services the two companies develop together under the new partnership.

There is also a competitive motive worth noting. Mastercard acquired BVNK, one of Visa's key stablecoin settlement partners, on August 18. Visa has since been looking for replacement settlement infrastructure. In this publication's analysis, GIWA's Optimism-based architecture and Dunamu's Korean regulatory connections make it a plausible candidate for that role in the Asia-Pacific market, though neither company has stated that framing explicitly.

Why This Matters Outside Korea

For readers in South Asia and Africa, the most concrete implication is in cross-border remittance costs. The World Bank estimates average global remittance fees at roughly 8.3 percent of the transfer amount. Stablecoin rails, in live deployments on emerging market corridors, have brought that figure below 0.1 percent. South Korea hosts significant migrant worker communities with substantial remittance flows, including more than 180,000 Thai residents. K Bank, Upbit's real-name account banking partner, is already piloting blockchain remittance to Thailand and the UAE. Notably, K Bank's contract with Upbit is set to expire in October 2026, a deadline that adds urgency to Dunamu's current push to deepen its financial infrastructure partnerships.

If Dunamu and Visa build functioning stablecoin remittance corridors on GIWA, the result is potentially sub-cent settlement into markets that currently depend on SWIFT correspondent chains. Visa's network spans more than 200 million merchants and 15,000 financial institutions globally, and the company already operates more than 160 stablecoin-linked card programs in over 50 countries. Analytically, that distribution would give GIWA-originated stablecoin value somewhere to land without requiring recipients to navigate crypto exchanges. That outcome is not guaranteed; it is the structural case for why the partnership matters beyond Korea's borders.

Ripple has already signed deals with Jeonbuk Bank and K Bank for Korea-Southeast Asia remittance. A Dunamu-Visa stack running on GIWA would introduce a competing set of rails. Given Visa's merchant reach, the end-user addressable market is significantly wider than what institutional bank partnerships alone can cover.

Dunamu's Broader Consolidation

This announcement does not happen in isolation. In July 2026, Dunamu and Hana Financial Group announced an alliance to build a Korean won stablecoin on GIWA and develop cross-border remittance products, security token offerings, and real-world asset tokenization. Hana Financial paid roughly $670 million for a 6.55 percent stake in Dunamu in May, becoming the company's fourth-largest shareholder. Samsung SDS confirmed active discussions with Dunamu on joint stablecoin and AI payment infrastructure as of late July, following Samsung affiliates collectively acquiring a 4 percent stake in Dunamu in May. A $10.3 billion all-stock acquisition bid for Dunamu by Naver Financial, a subsidiary of Naver Corp. (one of South Korea's largest internet companies), was set for a stock exchange on June 30, 2026, subject to Fair Trade Commission approval; if completed, it would make Dunamu a subsidiary of Naver Corp.

The single largest risk to this partnership's timeline is regulatory. South Korea's Financial Services Commission is working toward a Framework Act on Digital Assets before the end of 2026. Proposed rules include 100 percent reserve requirements for stablecoin issuers, held in licensed banks. At the center of the political debate is a question that determines the entire commercial structure of any Korean stablecoin product: whether banks or technology companies are permitted to issue stablecoins at all. Regulators remain divided on this specific point. If legislation lands closer to a bank-first model, Dunamu would need Hana Financial at the center of any Korean stablecoin product, which it is already positioning for. If regulators open issuance to technology companies, the calculus changes entirely.

The broader political environment is more favorable than it has been in recent years. President Lee Jae-myung's administration has taken an explicitly pro-crypto stance, framing 2026 as a turning point where South Korea moves from treating crypto as a threat to treating it as an economic tool. That posture makes regulatory progress more achievable in principle, and it is the context within which Dunamu's current expansion is taking shape.

Either way, the Visa deal gives Dunamu global distribution before Korea's stablecoin rules are finalized. In this publication's reading, securing that international foothold ahead of the domestic regulatory outcome is a deliberate strategic move rather than coincidental timing.
