Coupang and Woori Bank Complete Stablecoin Test for Real-Time Coupang Eats Merchant Settlements

Coupang, the South Korean e-commerce giant, and Woori Bank have completed a technical verification test using a won-denominated stablecoin to settle Coupang Eats payment proceeds with merchants in real time. The test lays the groundwork for commercial deployment once relevant legislation is enacted, according to a report by CoinReaders.

How the Stablecoin Settlement Test Worked

The test implemented a process in which, after a Coupang Eats order payment was completed, the funds were transferred and settled to a merchant’s electronic wallet through stablecoins. Woori Bank handled the on- and off-ramp system linking electronic wallets and bank accounts, enabling seamless conversions between stablecoins and fiat currency.

This approach bypasses traditional settlement delays, which can take one to two business days in South Korea’s food delivery market. By using a stablecoin pegged to the Korean won, both Coupang and its merchants could access funds almost instantly, improving cash flow for small and medium-sized restaurant partners.

Why This Matters for South Korea’s Digital Payment Landscape

South Korea has one of the most advanced digital payment ecosystems in the world, but real-time settlement for delivery platforms has remained a pain point. Merchants often wait days for payment proceeds, creating working capital challenges. A stablecoin-based solution could reduce settlement times to seconds, provided the regulatory framework supports it.

The test by Coupang and Woori Bank is among the first in South Korea to demonstrate a practical, non-speculative use case for stablecoins in commercial payments. It signals growing interest from major financial institutions and tech companies in blockchain-based settlement systems, particularly those that integrate with existing banking infrastructure.

Regulatory Hurdles Remain

While the technical test was successful, commercial rollout depends on legislative progress. South Korea’s National Assembly has been deliberating on digital asset and stablecoin regulations, but no specific law has been passed yet that explicitly permits stablecoin use for merchant settlements. Both Coupang and Woori Bank are expected to engage with regulators to clarify the legal status of such transactions.

The test also aligns with the Bank of Korea’s ongoing research into a central bank digital currency, though the stablecoin used in this test is issued by a private entity and pegged to the won.

Conclusion

The successful stablecoin test by Coupang and Woori Bank represents a meaningful step toward modernizing merchant payment settlements in South Korea’s competitive food delivery market. If regulatory conditions align, real-time stablecoin settlements could become a standard feature, benefiting thousands of Coupang Eats merchants. The development also underscores the broader trend of traditional financial institutions exploring blockchain-based payment rails for practical, everyday use cases.
