BTQ Technologies Corp. said it has been named security partner for MoonPay Korea’s stablecoin infrastructure, according to the company’s designated news release. The partnership is designed to bring post-quantum security to Korean won stablecoins from issuance through wallets, settlement and last-mile delivery to users and merchants.
BTQ will help MoonPay Korea prepare its full-stack infrastructure for quantum-related threats. The two companies plan a phased post-quantum security roadmap and will conduct a proof of concept with Korean banking institutions, testing BTQ’s Quantum Secure Stablecoin Network, or QSSN, for quantum-safe transaction signing and key management. The security focus follows broader industry work on post-quantum readiness, including Tezos Launches Quantumnet Post-Quantum Testnet.
MoonPay Korea’s infrastructure links Korean won-backed stablecoins to MoonPay’s global network serving more than 35 million customers in about 180 countries and over 1,500 enterprise clients. That global reach resembles payment-network upgrades such as Atum Launches Open Payments Network for Money Movement, where infrastructure changes are aimed at faster or more flexible money movement.
The Korean banking proof of concept will test quantum-safe signing and key management in a live institutional setting rather than only in a controlled environment. If it succeeds, it could strengthen the case for applying post-quantum controls to other institutional stablecoin projects, just as settlement experiments like Lloyds and Visa Complete First USDC Settlement Pilot have tested new settlement workflows with established financial institutions.
Post-Quantum Security Across the Stablecoin Stack
The arrangement spans distribution, wallets, settlement and last-mile delivery, which means the security layer cannot be limited to the issuance point. BTQ’s QSSN is intended to support quantum-safe transaction signing and key management across the stack. MoonPay Korea’s connection to a global network also raises the operational stakes: security faults in a full-stack stablecoin rollout would affect cross-border settlement and enterprise clients, so the phased roadmap is likely to prioritize backward compatibility and key-management usability. That operational surface also increases the value of phased deployment because banks can evaluate compatibility before a broader rollout.
What to Watch in the Roadmap and Bank Test
BTQ did not disclose financial terms. The immediate signal to watch is whether the Korean banking proof of concept produces measurable results that lead to broader deployments, and whether the post-quantum security roadmap extends beyond the initial partnership. For market participants, the announcement shows stablecoin infrastructure development moving beyond basic issuance to resilience planning, bank integration, and global distribution readiness. Execution milestones therefore become the clearest near-term gauge.
