Visa has expanded its digital assets division in South Korea through a partnership with Dunamu, the operator of Upbit—the country's largest cryptocurrency exchange by volume—signaling intensifying competition among global payments networks to capture stablecoin payment flows in one of Asia's most crypto-adopted economies.

Market Context

The deal comes just days after Visa announced a similar settlement infrastructure agreement with Shinhan Financial Group, South Korea's largest financial conglomerate. Together, the partnerships position Visa at the center of the country's push to build stablecoin payment rails, targeting an estimated 16 million crypto users in a nation where digital asset adoption ranks among the highest globally.

Analysis

Dunamu, which operates Upbit commanding roughly half of South Korea's spot exchange volume according to industry trackers, plans to work with Visa on financial services using stablecoins and artificial intelligence. The collaboration will examine payment and settlement models based on OUSD, an open-standard stablecoin, as well as infrastructure enabling AI agents to autonomously search for products and execute purchases on users' behalf.

The timing reflects broader institutional momentum: Samsung acquired a 4% stake in Dunamu in May, while Mirae Asset disclosed $109 billion crypto ambitions last week for the Digital X exchange it purchased in July. CEO Oh Kyung-seok framed the initiative as part of a larger transformation. "AI, stablecoins and tokenization are key trends that will reshape how finance and commerce operate," he told the Korea Herald.

Yat Siu, co-founder and executive chairman of Animoca Brands, recently echoed similar sentiment on autonomous machine transactions. "It is going to be a long while before any bank opens a bank account for an AI agent," Siu said. "Crypto basically solves all of that."

Key Numbers

- 16 million estimated cryptocurrency users in South Korea, per CoinGecko data

- $109 billion crypto ambitions disclosed by Mirae Asset for Digital X exchange

- 4% stake in Dunamu purchased by Samsung in May

- OUSD open-standard stablecoin serving as the pilot settlement model

What to Watch

Traders should monitor whether Visa extends similar frameworks to other regional partners. The Shinhan deal, announced earlier this week, focused on settlement infrastructure and may provide precedent for how Dunamu integration unfolds. Cross-border stablecoin payment standards remain in early regulatory review globally, making South Korea's sandbox approach a potential template. Key levels: Watch USD/KRW alongside any tariff-adjacent rhetoric that could pressure Korean financial stocks with crypto exposure.

Dunamu shares, if publicly tradable, would merit close observation given the strategic endorsement from both Visa and Samsung.
