BTQ Technologies' QSSN Selected as Core Security Infrastructure for South Korea's First Bank-Led KRW Stablecoin Proof-of-Concept
Rhea-AI Summary
BTQ (Nasdaq: BTQ) was selected as the core post-quantum cryptography (PQC) security provider for South Korea's first bank-led KRW stablecoin proof-of-concept on May 6, 2026. BTQ will supply its Quantum Secure Stablecoin Settlement Network (QSSN), provide strategic advisory, and coordinate implementation with iM Bank and Finger on the Kaia mainnet.
The pilot validates real-time bank-to-blockchain reconciliation, a global-standard smart contract architecture, overseas distribution connectivity, and a PQC dual-signature design that layers NIST-aligned PQC with existing ECDSA to enable phased quantum migration.

Crypto-tagged announcements often led to sizable moves, with mostly positive reactions but two notable selloffs on otherwise positive crypto infrastructure updates.
Over the last several months, BTQ’s crypto-tagged news has centered on Bitcoin Quantum and quantum-safe digital money infrastructure. Launch of the Bitcoin Quantum testnet, subsequent BIP 360 deployment, and research coverage all highlighted BTQ’s focus on post-quantum security for Bitcoin-style networks. A full-year 2025 update emphasized live QSSN pilots in South Korea and broader quantum initiatives. Today’s iM Bank KRW stablecoin proof-of-concept extends that trajectory into regulated Korean banking infrastructure, reinforcing BTQ’s strategy around post-quantum financial rails.
Historical Comparison
Crypto-tag news for BTQ has produced an average 6.04% move, with both strong rallies and occasional selloffs on positive quantum-infrastructure milestones.
Historical crypto news traces a path from Bitcoin Quantum testnet launch through iterative upgrades and corporate updates to QSSN pilots, now expanding into KRW stablecoin banking infrastructure.
Market Pulse Summary
This announcement extends BTQ’s post-quantum financial strategy by making QSSN the core security layer for a bank-led KRW stablecoin proof-of-concept on the Kaia mainnet. It builds on prior Korean pilots and recognition in frameworks such as PQFIF, tying BTQ deeper into regulated digital money infrastructure. Investors may watch for conversion of this proof-of-concept into commercial deployments, further banking partners, and continued progress across BTQ’s broader quantum-security product stack.

BTQ provides strategic advisory support and QSSN as core PQC security infrastructure for the iM Bank initiative on the Kaia mainnet, advancing post-quantum migration across global financial infrastructure
- 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 andJapan .
The proof-of-concept represents more than a technical pilot. It marks an important step in bringing next-generation quantum security into banking infrastructure within
"Post-quantum migration requires more than a cryptographic upgrade. It requires coordination across infrastructure, implementation, and institutional stakeholders," said Olivier Roussy Newton, Chief Executive Officer of BTQ Technologies. "In this initiative, BTQ is providing both strategic advisory support and QSSN as the post-quantum security architecture, while helping lead coordination across the three-way partnership. We believe this proof-of-concept demonstrates how financial institutions can begin integrating quantum-resilient protections into digital money systems in a practical and operationally viable way."
BTQ is working alongside iM Bank and Finger on a three-way initiative to validate the issuance and distribution infrastructure for a Korean won stablecoin. In addition to supplying QSSN as the PQC security layer, BTQ is providing consulting support and helping to guide coordination across the partnership as the parties evaluate how to integrate post-quantum protections into bank-led digital asset infrastructure.
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.
Built on Kaia Mainnet
A notable feature of the proof-of-concept is that it will be implemented on the Kaia mainnet, one of
Klaytn previously participated in the Bank of
By combining BTQ's PQC technology with blockchain infrastructure tied to the Kakao and LINE ecosystems, the proof-of-concept is intended to establish a model that aligns institutional-grade security, blockchain scalability, and evolving regulatory requirements for digital money infrastructure.
QSSN as the Security Layer
The PQC security foundation for the initiative is BTQ's Quantum Secure Stablecoin Settlement Network, or 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.
BTQ has previously announced that QSSN was highlighted in the
Addressing the Harvest-Now, Decrypt-Later Risk
The timing of the proof-of-concept reflects the growing urgency surrounding the "Harvest-Now, Decrypt-Later" risk, in which attackers may collect encrypted financial data today and decrypt it later once sufficiently advanced quantum capabilities emerge. Global institutions are already accelerating post-quantum migration. The
BTQ's QSSN addresses this challenge through a dual-signature design that allows existing ECDSA-based infrastructure to operate in parallel with NIST-aligned PQC signatures such as ML-DSA. This approach enables banks and payment infrastructure providers to begin a phased transition toward quantum-safe security without disrupting existing systems.
Expanding BTQ's Korean Ecosystem
BTQ continues to expand its Korean ecosystem across digital assets, payments, banking infrastructure, and hardware-based security. In October 2025, BTQ announced that Finger had joined Danal as an early participant in BTQ's QSSN pilot program, with the initiative expected to progress from proof-of-concept toward commercialization under QuINSA-aligned guidelines and broader industry frameworks such as PQFIF.
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. As
