South Korea has launched its first bank-led Korean won (KRW) stablecoin proof-of-concept, selecting BTQ Technologies as the core post-quantum security provider. BTQ will implement its Quantum Secure Stablecoin Settlement Network within iM Bank's pilot infrastructure, in collaboration with local technology vendor Finger Inc. The initiative aims to embed quantum-resilient cryptography into a regulated KRW stablecoin on the Kaia mainnet, a network formed from the merger of Klaytn and Finschia. The pilot will test real-time reconciliation between bank reserves and on-chain supply, standardized smart contract design, and overseas distribution connectivity. This move comes as eight Korean banks plan a joint venture to issue a KRW stablecoin, aiming to strengthen domestic financial independence amid concerns over foreign digital currencies. BTQ's involvement highlights the growing importance of quantum security in financial systems, as the project aligns with the US Post-Quantum Financial Infrastructure Framework.
