Four global crypto infrastructure firms court Korean banks before any vendor dominates the stack

Seoul Economic Daily's report does not include contract values, fees or volumes for any of the four global entrants ^[4][5][6][7]. They are coming in on the view that a Korean market built around exchanges could widen into selling to financial institutions ^[10]. According to industry sources cited by the paper, banks that want to issue stablecoins or handle tokenized assets need wallets, custody, links to existing networks and settlement, and no operator dominates yet ^[9]. Of the four global entrants, one is building with a bank, one holds a registration and two are still in talks ^[2].

KakaoBank appears on two of those lists, MoonPay's and Fireblocks' ^[1]. A bank in talks with two vendors at once has not picked a single supplier. Lee Bu-gun, MoonPay's co-founder and Asia-Pacific head, is selling the single-supplier version. "There is effectively no competitor in Korea doing business as comprehensively as we are," he said at a Seoul briefing on Sept. 29 ^[1].

This can settle three ways. Banks can buy the full stack from one vendor, and MoonPay is betting on that. They can buy it by layer. The report puts Dunamu's strength in chain and wallet, LG CNS's in building financial systems, and NHN KCP's and Hecto Financial's in payments and settlement, and says the firms are not squaring off head-to-head ^[17]. NHN KCP is already commercializing stablecoin settlement with financial institutions and platforms ^[15], and Hecto is aiming stablecoins at corporate cross-border remittances ^[16]. Or banks can own part of the vendor, as Hana Financial Group and SK Telecom do as strategic shareholders in BitGo Korea ^[8].

LG CNS is building its own comprehensive offering ^[13]. "In the digital asset business, global companies are the main competitors," an LG CNS official said ^[14].

Dunamu is coming at tokenized assets from the investor side. Its GIWA Wallet lets verified qualified investors join public offerings of security tokens and link crypto held on Upbit and other platforms ^[11]. Tokens bought through it can carry a mandatory holding period, after which they can be transferred to another qualified investor ^[12].

I think Korea's bank stack splits by layer. The evidence is KakaoBank's two tracks ^[1] and eight named firms with mostly separate strengths ^[3][17]. The counter-case is that two sets of talks make a bake-off, and a bake-off ends with one supplier. If KakaoBank or KB gives MoonPay stablecoins, cross-border remittances and payments in a single agreement, the full-stack model has its first bank and the layered view is wrong ^[4].
