South Korea’s BC Card completed a proof-of-concept on Aug. 12, 2026, that lets foreign visitors pay at domestic QR merchants using USDC from a Base-network wallet, with the merchant still settling in Korean won.
Digital-asset infrastructure firm Wavebridge built the conversion layer that made the test work, and BC Card confirmed the payment rails held up on their end. No currency exchange step was required at the point of sale.
Wavebridge and BC Card Confirm the Stablecoin-to-Won Bridge Works
The core problem the PoC solved is a plumbing one. A stablecoin sitting in a foreign visitor’s wallet cannot reach a Korean merchant as a won-denominated settlement unless something in the middle converts it.
Wavebridge, whose virtual-asset service provider notification was accepted by Korea’s Financial Intelligence Unit, verified that segment: receiving the stablecoin, custodying it, converting it to won, and passing it into BC Card’s existing settlement process.
The test ran on Base, the public blockchain network built by Coinbase, using its Base Pay payment infrastructure as the settlement mechanism on the wallet side.
The companies also tested what happens when a transaction fails or gets canceled. By linking BC Card’s cancellation process to Wavebridge’s on-chain asset return, the stablecoin flows back to the customer’s wallet instead of getting stuck, addressing one of blockchain’s harder practical problems around irreversible transactions.
Timing matters here. Korea welcomed a record 18.94 million foreign visitors in 2025, and BC Card’s network covers 3.5 million merchants nationwide. A working stablecoin-to-won bridge at that scale would let tourists skip currency exchange counters entirely while merchants keep the card terminals they already use.
The Road to Commercial Launch
Wavebridge says it plans to move from this controlled test into production blockchain environments next, building out risk-management systems as it works toward regulatory approval for a commercial rollout.
No launch date has been announced, and the current PoC ran only on Base’s testnet and pre-production environments, so actual availability for travelers remains some way off.
What this means for you: if you’re a crypto holder planning to visit South Korea, this points toward a future where your USDC could work directly at local shops without a trip to a currency exchange booth, though the system is still in testing and not yet available to the public.
