Korea’s Won Stablecoin Race Shifts to Infrastructure and Institutional Control

Competition to define Korea’s emerging won-denominated stablecoin rails is accelerating, as researchers warn that the next phase of crypto market evolution will be driven less by headline-grabbing technology and more by who controls ‘liquidity’, ‘infrastructure standards’, and institutional-grade settlement.

A weekly research briefing from multiple analytics firms highlights a converging theme: while retail-led speculation has cooled, infrastructure players and institutions are positioning for a market structure shaped by payments integration, collateral efficiency, and regulatory clarity—especially around Korean won stablecoins.

Payment giants eye on-chain won rails

Exilist said momentum is building after reports that Toss—one of South Korea’s largest fintech platforms—has been reviewing the launch of its own mainnet and a native token. The firm pointed to signals such as won stablecoin trademark filings and wallet integration strategies as evidence the initiative is moving beyond experimentation toward potential commercialization.

With an estimated user base of roughly 30 million, alongside a growing footprint in merchant payment terminals and app-based “mini-app” distribution, Toss could be positioned to capture meaningful share of future won stablecoin circulation and settlement routes, Exilist argued. In that scenario, the strategic prize is not simply issuing a token, but controlling a widely adopted ‘settlement rail’ that ties consumer wallets, merchant acceptance, and on-chain liquidity together.

However, Exilist also cautioned that South Korea already operates highly advanced payment infrastructure, making user adoption—and the ability to embed stablecoin functionality into everyday financial behavior—more decisive than pure technical performance. The firm framed the core contest as a standards battle: as won payments begin to move on-chain, the market will likely coalesce around whoever becomes the de facto interoperability and compliance standard.

Kaiko flags ‘collateral fragmentation’ as a structural barrier

Kaiko Research focused on a different friction point: the growing ‘fragmentation’ of crypto collateral across exchanges, blockchains, and protocols. According to Kaiko, this splintering has become a structural obstacle for institutions that require predictable execution, reliable liquidity, and efficient capital deployment.

Kaiko noted that Bitcoin (BTC) order-book depth can vary by as much as threefold across venues, while price dislocations tend to widen during periods of stress—symptoms of liquidity fragmentation that become more costly when large size must be executed quickly. Stablecoin liquidity is also scattered across more than 15 chains, the firm said, and the rapid proliferation of tokenized Treasury products is creating new “collateral silos” with differing structures and settlement pathways.

Cross-chain movement, Kaiko argued, adds layers of fees, operational risk, and settlement uncertainty. The problem becomes more visible on weekends, when thinner liquidity can push trading costs meaningfully higher than models based on weekday conditions would suggest. The net effect, in Kaiko’s view, is that fragmentation undermines one of crypto’s core promises—efficiency—while raising both the entry barriers and day-to-day operating complexity for institutional participants.

DeFi strategies mature as Korea shifts toward institutions

Tiger Research highlighted how decentralized finance is adopting increasingly traditional portfolio construction methods—an evolution that aligns with the needs of professional allocators. As an example, the firm pointed to Solstice Finance, which it described as building layered yield products by importing methods from traditional finance.

Solstice Finance’s approach centers on USX and a delta-neutral strategy product, eUSX, designed to seek more stable returns by reducing exposure to directional volatility. Tiger Research said the model attempts to offset potential declines in funding-rate income by combining tokenized Treasury exposure and staking-based strategies, resulting in a blended structure rather than reliance on a single yield driver. If additional products such as strcUSX and oUSX are launched, the platform could strengthen its competitiveness within on-chain asset management, the firm added.

In parallel, Tiger Research argued that South Korea’s crypto market is increasingly being reshaped by institutional flows as retail participation moderates. While early market cycles were driven heavily by individual investors, the firm said recent project volatility and policy shifts have contributed to fatigue among retail participants. Institutions, by contrast, are steadily expanding their footprint and forming more stable, programmatic capital flows.

The same dynamic could extend to won stablecoins, Tiger Research suggested, with financial institutions potentially playing a central role as the market matures. In that framework, regulation and policy direction—rather than purely technical capability—may become the primary determinants of which issuers and infrastructures dominate.

Overall, the research converges on a single takeaway: crypto’s next inflection point in Korea may be defined by ‘market microstructure’ and ‘infrastructure control’—from how collateral moves across venues to which platforms become the trusted rails for on-chain won settlement—signaling a broader shift from retail-led experimentation toward institution-led standardization.
