Hanbank under the JB Financial Group in Korea, together with the Solana Foundation and Node Infra, completed a stablecoin cross-border remittance PoC:
In a real banking business environment, they connected the end-to-end process—KRW on-ramp, stablecoin exchange, bank custody, cross-border settlement, and payment to local banks.
Two details are worth noting—the solution runs on Solana’s private channels; the counterparties and amounts are not directly exposed to the public chain, only the funding deposit and the final settlement outcome are recorded on-chain;
The stablecoin exchange is also handled by the bank custody system and does not go through any external cross-chain bridge.
Hanbank said that once relevant regulations in Korea are implemented, it will integrate the technology into Bravo Korea, a service for foreign residents in Korea.
What banks have always wanted isn’t “going on-chain”—it’s being auditable yet not transparent.
