MoonPay and Dunamu, the operator of South Korea’s Upbit cryptocurrency exchange, have announced plans to explore stablecoin-based cross-border payments, corporate treasury services and international access to Dunamu’s GIWA Ethereum Layer 2 network. The collaboration brings together a payments infrastructure provider with the owner of one of Asia’s largest crypto exchanges, but stops short of launching a jointly operated payment product.
The companies’ October 20 U.S. announcement, issued on the morning of October 21 in South Korea, identifies three workstreams: moving funds internationally using stablecoins, assessing blockchain-based corporate finance and treasury management, and connecting MoonPay’s distribution network with applications built in the GIWA ecosystem.
For investors, the development is less about a new token listing than about whether infrastructure originally developed around cryptocurrency trading can win a role in routine business payments. Neither company disclosed binding commercial volumes, implementation fees, supported stablecoins, a launch schedule or a commitment to issue a new token.
What Have MoonPay and Dunamu Actually Agreed to Explore?
In the official collaboration announcement, MoonPay said the parties would identify potential uses for stablecoin payments and international fund transfers, evaluate digital-asset infrastructure for corporate finance and treasury operations, and seek ways to expand GIWA services beyond South Korea.
The language is deliberately exploratory. The release says the companies intend to establish the commercial and technical potential of these areas rather than announcing that merchants, banks or treasurers can already use a newly integrated MoonPay-Dunamu service.
MoonPay’s Asia-Pacific head Bugeon Lee described the opportunity as connecting stablecoins to the financial operations of real businesses, rather than limiting them to transfers between cryptocurrency traders. That is an important strategic signal: enterprise treasury tools must solve payment collection, cash positioning, settlement and reconciliation problems before corporate finance teams can justify replacing existing processes.
MoonPay says its broader business serves more than 35 million customers across 180 countries and over 1,500 enterprise clients. Those company-reported figures describe its global footprint, not the number of customers or merchants committed to the Dunamu project.
At this stage, there is also no disclosed exclusive arrangement, equity investment, guaranteed transaction volume or revenue-sharing formula. Describing the announcement as a completed merger or an operational global stablecoin payment corridor would therefore overstate the available evidence.
Why Is Dunamu’s GIWA Network Central to the Plan?
GIWA is an Ethereum Layer 2 blockchain developed with Upbit and built using the OP Stack, the technology associated with Optimism. Its official documentation emphasizes compatibility with Ethereum applications, lower transaction costs and one-second block production as design characteristics.
The project’s name expands to Global Infrastructure for Web3 Access. That ambition explains why Dunamu could value a partner with international payment and onboarding relationships: building a blockchain network is different from persuading developers, merchants and customers outside the home market to use it.
MoonPay could potentially help connect applications built on GIWA to external payment rails and users. But the announcement does not name a particular wallet integration, bridge deployment, merchant, exchange listing, bank or stablecoin issuer that has agreed to launch on GIWA as part of this initiative.
The Optimism Foundation’s May statement described GIWA as an OP Stack-based network that was running a testnet, with mainnet to follow. GIWA also stated in late September that its mainnet had not yet launched. The MoonPay agreement should not be treated as confirmation of a live production mainnet or operational payment settlement on the chain.
For Layer 2 networks, adoption depends on more than transaction speed. Stablecoins need trustworthy issuers and liquid redemption channels; businesses need account access, compliance screening, customer support and reliable connections to banks. Developer tools are necessary, but do not provide those services by themselves.
Why Would Upbit’s Parent Move Toward Corporate Treasury?
Dunamu has built its business around digital-asset trading and related infrastructure. Expanding toward business payments would potentially diversify the sources of activity that flow through its technology, reducing dependence on retail cryptocurrency turnover if services eventually reach commercial scale.
The collaboration also fits a wider Korean financial-services strategy. Dunamu has been pursuing a stock-swap combination with Naver Financial, the fintech arm associated with the Korean internet group, with stablecoin and payment applications among the opportunities discussed. That transaction remains subject to its relevant process and should not be described as already completed merely because MoonPay announced a separate collaboration.
Earlier in 2026, Hana Bank moved to buy a 6.55% stake in Dunamu for around one trillion won. The investment underscores growing interest among Korean financial institutions in digital-asset infrastructure, though it is not a disclosed financing contribution to this MoonPay partnership.
Corporate treasury is a more demanding market than retail crypto conversion. A finance department may need to fund payroll and suppliers in several currencies, control which employees can authorize payments, verify beneficiary identities and reconcile every transfer with its accounting system.
As DaveFinances explored in its analysis of stablecoins moving into corporate finance, faster blockchain settlement is only one piece of a broader operational change involving banking relationships, payment controls and cash-management systems.
Could Stablecoins Make Cross-Border Payments Cheaper?
A stablecoin can allow a payment provider to move dollar-denominated value over a blockchain outside the operating hours of some traditional settlement networks. That can shorten the time between initiating a transfer and recording its receipt, particularly where funds otherwise pass through several banking intermediaries.
However, blockchain transaction speed is not the same as the time it takes a business to receive spendable local currency. A payment may still depend on cashing out through a regulated partner, maintaining local bank liquidity, completing compliance checks and handling currency conversion.
Consider a company moving $1 million between two countries. If a stablecoin transfer settles quickly but the receiving partner lacks enough local liquidity to provide fiat money, the company’s payable can still be delayed. The blockchain leg has improved, but the end-to-end treasury process has not necessarily become more reliable.
The economic comparison must also include spreads, redemption charges, custody, gas fees, banking fees and the cost of holding liquidity in advance. Neither MoonPay nor Dunamu has disclosed transaction pricing or evidence of cost savings from their proposed collaboration.
The risks of depending on an issuer also matter. In a dispute over frozen USDT allegedly used as corporate operating cash, the practical issue was whether money a business counted as liquid remained accessible. That independent case illustrates a risk treasury teams would have to address before relying on any stablecoin-based workflow.
What Would Turn the Announcement Into a Real Business?
The most important next milestone would be a named product with a defined set of supported stablecoins, payment routes, business customers and launch jurisdictions. Firms should also specify which legal entity provides custody, converts fiat, executes payments and assumes liability when transfers fail or require reversal.
GIWA’s production readiness is another condition to watch. An exchange-affiliated chain might offer attractive technology, but treasury customers need dependable operations, documented service levels, independent security review and practical ways to exit into bank deposits.
South Korea’s developing Digital Asset Basic Act and debates around won-pegged stablecoins could shape which institutions may issue or distribute certain instruments. A partnership announcement does not substitute for any required licenses or authorizations in Korea or in overseas markets.
The competitive market is already crowded. OKX recently introduced a consumer-facing stablecoin application, while a range of payment providers are marketing blockchain settlement to businesses. MoonPay and Dunamu will therefore have to demonstrate a useful combination of regulated access, user distribution and GIWA infrastructure rather than relying on the fact that their organizations are well known.
For now, the confirmed development is an agreement to explore a broader stablecoin and treasury business, together with possible international distribution for GIWA. No production payment corridor, new issuance program, financial commitment or resulting revenue has been established. Those would be the disclosures that turn the collaboration from a strategic statement into a measurable operating initiative.
