KRWQ brings Korean won FX markets onchain to cut trading costs by 50–75%

As KRWQ moved from concept to live trading, the challenge became straightforward: build deep, dependable KRW-USD liquidity that could extend beyond crypto-native venues and into institutional workflows. Without a widely accepted USD settlement asset, KRW markets would stay fragmented, making tight spreads, efficient arbitrage, and broader adoption much harder. That’s because market makers and institutional traders are less willing to commit capital when settlement happens across multiple USD proxies or thin liquidity pools, making hedging slower, pricing less consistent, and execution risk harder to manage.

Why USDC became the institutional-grade USD leg for KRWQ markets

To compete with established FX infrastructure, KRWQ needed a settlement asset that traders, exchanges, and institutional venues already trusted, and that could work across both DeFi liquidity and centralized market structure.

USDC met those requirements, so IQ chose KRWQ-USDC as its primary settlement pair to:

• Build deeper KRW–USD liquidity and improve price formation
• Support institutional products where settlement conventions matter
• Make KRW exposure easier to distribute through existing crypto and traditional trading rails

Launching KRWQ on Base, the Ethereum Layer 2, reinforced that choice. USDC already had liquidity and distribution across the Base ecosystem, making it the obvious counterparty for KRWQ from the start. That let the IQ team focus on liquidity formation and real FX use cases instead of building a new USD leg from scratch.

The importance of that choice became evident as KRWQ expanded into institutional products such as derivatives. At that point, settlement asset quality became a real requirement.

In practice, IQ implemented USDC mint and redeem flows to support KRWQ’s market structure and trading activity, using USDC as the settlement layer behind KRW-denominated products and KRW-USD liquidity across venues.

What changed: Fragmented KRW liquidity to scalable KRW–USD market structure

Before integrating directly around USDC, KRWQ faced a familiar challenge for non-USD currencies onchain: liquidity was splintered across venues and assets, spreads were wider than necessary, and it was difficult to support institutional workflows that depended on a consistent settlement standard.

By building KRWQ markets around USDC, KRWQ could anchor KRW liquidity to a USD-denominated digital asset already broadly used across:

• Decentralized trading and market making
• Centralized exchange infrastructure
• Institutional venues designing crypto-linked market structure

That shift mattered because it made KRW exposure easier to trade. Deeper KRWQ-USDC liquidity supports tighter quoting and more reliable arbitrage, which improves price discovery and makes KRW products easier to distribute.

It also broadened what IQ could bring to market. KRWQ has served as the foundation for new onchain FX products, including KRW perpetual futures launched with EDXM International and distributed through traditional FX infrastructure, settled in USDC.

The IQ team says scaling KRW-USD markets without USDC would have been much harder. Liquidity would have remained more fragmented, spreads would have stayed wider, and integrating KRW exposure into institutional venues would have been more difficult.

Results: Lower-cost KRW trading and institutional distribution with USDC settlement

The clearest impact of pairing KRWQ with USDC has been on cost and market efficiency in KRW trading products built on KRWQ, particularly in the effort to create an onchain alternative to the traditional KRW NDF structure.

Compared with traditional KRW NDF markets, where trading passes through multiple intermediaries and carries higher structural costs, the KRWQ-USDC perpetual futures launched with EDXM International have delivered trading costs that are 50%–75% lower. Those gains come from tighter spreads, continuous liquidity, and fewer layers of intermediation than legacy setups.

Historically, offshore KRW exposure was routed through opaque, institution-only NDF infrastructure with higher costs and limited transparency. Pairing KRWQ with USDC created an onchain KRW-USD settlement layer that supports institutional-grade products and lower-cost access.

The qualitative impacts go beyond pricing. Using USDC as the USD settlement leg strengthened KRWQ’s position with institutional counterparties, including venues and partners tied to traditional market structure. For end users, that means KRW exposure that is easier to access and more efficient to trade, with tighter spreads and lower costs than traditional NDF channels.

The IQ team also credits USDC’s existing distribution and infrastructure with shortening time to market. Instead of having to establish a bespoke USD settlement standard, KRWQ could build on an existing asset and focus on liquidity and product design.

What’s next

After showing meaningful cost savings and better market access, the IQ team expects USDC to remain central as it expands into a broader onchain FX market, especially as institutional products grow in areas where USDC settlement is already standard. The team also sees room to grow through broader distribution, including introductions to exchanges, market makers, and institutional trading firms, along with co-marketing that can speed adoption of KRW-USD markets.

For institutional traders and FX participants looking for more efficient Korean won exposure, KRWQ’s USDC-settled products offer a practical alternative to traditional NDF markets, with lower costs and better access.
