@BTQ_TECH has been selected as the core security layer for South Korea's first bank-led KRW stablecoin PoC 🇰🇷

@BTQ_TECH has been named the core security infrastructure provider for South Korea's first bank-led Korean won stablecoin proof of concept (PoC), marking a significant step in the institutional adoption of post-quantum cryptography (PQC) within regulated financial systems.

A Three-Way Initiative Built on Quantum-Safe Rails

BTQ has been selected as the core post-quantum cryptography security technology provider for South Korea's first bank-led KRW stablecoin proof of concept, delivering its Quantum Secure Stablecoin Settlement Network (QSSN) for the initiative. BTQ is providing strategic advisory support and helping coordinate implementation across the partnership with iM Bank and Finger, supporting the integration of post-quantum protections into regulated digital money infrastructure.

Built on the Kaia mainnet, the proof of concept is connected to the blockchain ecosystems originally developed by Kakao and LINE, linking the initiative to two of the largest messaging and digital platform ecosystems in Korea and Japan.

The proof of concept will validate several key components, including real-time reconciliation between bank reserves and blockchain-issued supply, a global-standard smart contract architecture, connectivity to global infrastructure for overseas distribution, and the integration of a PQC-based dual-signature security structure. By applying BTQ's PQC signature architecture alongside the existing ECDSA cryptographic framework, the system is designed to preserve operational continuity for financial institutions while proactively addressing future quantum computing threats.

Why Quantum-Safe Infrastructure Matters Now

The PQC security foundation for the initiative is BTQ's QSSN, a quantum-secure network architecture designed for stablecoin, tokenized deposit, payment, and digital asset infrastructure. QSSN is designed to protect critical issuer functions, including stablecoin issuance, burning, transfer authority, upgrade control, and administrative permissions, by integrating PQC-based signatures while maintaining existing user experience and operational workflows.

The commencement of the iM Bank proof of concept represents an important commercial signal for BTQ, indicating that demand for post-quantum migration among Korean financial institutions is beginning to move from policy discussion toward infrastructure-level implementation. BTQ has previously announced that QSSN was highlighted in the U.S. Post-Quantum Financial Infrastructure Framework (PQFIF) as a model architecture for post-quantum digital money infrastructure.

The development comes as South Korea's broader digital asset regulatory environment takes shape. The push follows an estimated $115 billion in capital that flowed from domestic exchanges into dollar-based stablecoins such as USDT and USDC in 2025, raising concerns about monetary sovereignty and capital outflows. The Digital Asset Basic Act is expected to clear the National Assembly in 2026, and for the first time in nearly nine years, Korean companies will be legally permitted to issue KRW stablecoins.

For $BTQ, the iM Bank PoC adds to a growing list of Korean engagements. The announcement reinforces BTQ's broader momentum in Korea, including recent progress with ICTK, Danal, Finger, and QSSN standardization efforts, positioning the company at the intersection of post-quantum hardware, payments, banking, and next-generation secure communications.
