BDACS, a South Korean digital-asset custodian, said won-backed stablecoins including its KRW1 could help internationalize the Korean currency by linking Korean and global capital in ways that were previously difficult.
Kim Tak-jong, BDACS co-founder and chief strategy officer, made the case at the “Toward On-Chain Finance” event at the Four Seasons Hotel in Seoul’s Jongno District on October 1. “An on-chain economy is being built around the world, but so far it has effectively been built on a single currency, the dollar,” Kim said. Won stablecoins are not meant to replace existing payment systems, he added, but to enable new types of transactions that were previously not possible.
The remarks appeared to address the dominance of dollar-backed stablecoins in the market. The global stablecoin market has a capitalization of about $300 billion, with 99.7% of the total made up of dollar-based stablecoins.
Kim said that if the imbalance persists, rising on-chain investment by Korean users could accelerate capital outflows into dollar stablecoins. About 47 trillion won ($33.9 billion) moved from domestic exchanges to overseas platforms in the first half of this year alone, he said, adding that the shift reflected unmet investment demand in Korea rather than tax evasion.
Korean capital and users have already entered the on-chain market, but they are not using the won, Kim said. Net stablecoin outflows from domestic exchanges in June alone exceeded 500 billion won ($361 million). If the only money available on-chain is the dollar, Koreans’ on-chain activity will also become dollar-based, he said, calling that not a user problem but a gap in Korea’s infrastructure.
Won Stablecoins Can Drive Won Internationalization
Kim said won-backed stablecoins could fill that gap. BDACS is launching KRW1, a won-based stablecoin, and building related infrastructure. KRW1 is backed one-to-one by Korean won held at domestic banks.
Kim cited three reasons won stablecoins are needed: the era of AI agents, settlement and financial applications for tokenized Korean assets, and stronger links between global capital and the Korean market.
“In an era when AI agents make payments on behalf of people, on-chain payment tools will be needed,” Kim said. “AI agents in Korea and around the world are likely to make payments for us in the future. Without on-chain won, all of those payment currencies will shift to the dollar.”
He also tied won stablecoins to South Korea’s tokenized securities market, which is nearing institutionalization. Tokenized bonds can move in seconds, but settlement can still take one or two days through the banking system, Kim said. Using won stablecoins such as KRW1 would allow bonds and Korean won to move simultaneously on-chain. He added that on-chain repurchase agreement, or repo, transactions would also be possible, allowing users to borrow won stablecoins against tokenized bonds as collateral and receive that collateral back once repayment is made.
Kim also said won stablecoins could help internationalize the won by improving connectivity between global capital and the Korean currency, laying the groundwork for wider international use.
“If someone in a market like New York, where business hours do not overlap with Korea at all, wants to buy won-based assets, they currently have to wait until Korea’s financial markets reopen,” Kim said. “But if won stablecoins exist, they can convert dollars into won on-chain and immediately buy Korean bonds.”
He added that if Korea moves toward a 24-hour foreign-exchange market and the won becomes tradable on-chain, overseas capital would be able to enter the Korean market without time constraints.
BDACS also demonstrated a foreign-exchange transaction on October 1 that swapped KRW1 and USDC in two seconds using Circle’s Arc blockchain.
Need for a ‘Balanced’ Regulatory Framework
Regulation remains a key unresolved issue. Standards for issuing won-backed stablecoins are still absent because South Korea has yet to establish a basic law governing digital assets.
Kim said a balance is needed between regulation and innovation. If regulation is excessive, related activity will move overseas, he said. If regulation is too weak, the trust needed for money to function can be lost. The goal, he added, is to find the point where regulation and innovation meet.
He also said BDACS has no intention of using KRW1 to circumvent regulation. KRW1 is issued by a digital-asset custodian regulated in Korea, and its reserves are held at domestic banks, he said. The goal is not to avoid Korean regulation but to bring Korean standards on-chain.
