BTQ Technologies Corp. ("BTQ" or "Company") (Nasdaq ticker: BTQ; CBOE Canada: BTQ) announces a strategic partnership with MoonPay Korea under MoonPay Inc. MoonPay is a global encrypted payment network. According to the partnership arrangement, BTQ will serve as MoonPay Korea's security partner in terms of stablecoin infrastructure in South Korea, with a focus on post-quantum cryptography (PQC).

BTQ indicates that MoonPay Korea is building full-stack on-chain infrastructure for South Korea's emerging won-backed stablecoin market, covering issuance support, distribution, wallet integration, settlement, currency conversion, as well as the last-mile delivery for users and merchants. The responsibility of BTQ is to protect this technology stack from current and future threats, including the risks posed by quantum computing to the encryption of digital assets.

The company stated that this collaboration will enable BTQ to enter one of the most innovative infrastructure constructions in the Korean stablecoin market and connect to a global network. MoonPay serves over 35 million customers, covering approximately 180 countries and regions, as well as more than 1,500 corporate clients. By integrating Korean won-backed stablecoins into this network for distribution, cross-border settlements, and wallet integration, BTQ aims to help protect the infrastructure in Korea, with the goal of reaching users and merchants worldwide.

The scope of cooperation includes:

• Quantum migration roadmap. BTQ and MoonPay Korea will jointly develop a post-quantum security roadmap for the stablecoin infrastructure of MoonPay Korea. The content includes a list of cryptographic assets, risk prioritization, and a phased migration plan.
• Conducts QSSN concept validation with the Bank of Korea. Through MoonPay Korea, BTQ will carry out concept validation with the Bank of Korea regarding its Quantum Secure Stablecoin Network ("QSSN"), testing quantum-safe transaction signatures and key management for wallets and settlement infrastructure that support stablecoins in Korean won.
• Overlapping security efforts across the entire stack. Both parties will advance post-quantum preparation work for each layer of the MoonPay Korea infrastructure, from issuance and distribution to wallets and final delivery.
• Collaboration with Korean financial institutions. BTQ will work together with MoonPay Korea and its banking and institutional partners to support the quantum security standards of the Korean won-backed stablecoin ecosystem.

MoonPay APAC stated that: "The stablecoin capabilities of MoonPay cover the entire stack, from issuance support to settlement and distribution. MoonPay Korea focuses on providing the 'last mile' services, enabling Korean partners to put these capabilities into use. As our security partner, BTQ will help us develop a post-quantum security roadmap and assess how their technology can support the long-term resilience of this infrastructure."

BTQ Technologies CEO Olivier Roussy Newton stated: "The stablecoin infrastructure in South Korea is under construction, with security design incorporated from the very beginning, and its durability will far exceed that of security measures implemented afterwards." MoonPay Korea is building one of the most comprehensive technology stacks on the market, from issuance to the final delivery stage. By becoming a security partner, BTQ's post-quantum technology can be directly integrated into the infrastructure that will support the operation of stablecoins in Korean won."

According to BTQ, South Korea is moving from bank-led stablecoin pilots towards domestic merchant adoption and cross-border settlements, and a regulatory framework for the Korean won to support stablecoins is also being established. MoonPay Korea provides infrastructure for distribution, cross-border settlements, wallet integration, and currency conversion in this market. The oldest commercial bank in South Korea, Woori Bank, is the first member of MoonPay Korea KRW Stablecoin Consortium.

Stablecoins that carry national currencies, held by self-managed wallets, and traded across borders rely on cryptography to authorize issuance rights, manage keys, and control transaction permissions. As quantum computers are expected to pose a threat to today's public key cryptography systems in the future, these systems need to remain secure for a very long time. Therefore, for the infrastructure of Korean stablecoins, post-quantum security is not a subsequent upgrade but a design requirement.

Building on the existing security framework for Korean stablecoins established by BTQ, this collaboration further enhances BTQ's position in the field of post-quantum security within Korea's digital asset infrastructure. BTQ previously announced that QSSN had been selected as the core security technology provider for the concept verification projects involving Finger Inc, iM, and Bank. This project, developed based on Kaia's mainnet, is South Korea's first bank-led won stablecoin infrastructure to incorporate post-quantum cryptography. BTQ has also reached commercial agreements with LINE NEXT and Kaia DLT Foundation to deploy QSSN within their ecosystems.

BTQ Chief Strategy Officer Youngsuk " Jeff " Choi indicates that 'South Korea is setting the pace for regulated, bank-grade stablecoins, and the infrastructure decisions made now will define the market for many years to come.' MoonPay Korea is delivering full-stack capabilities all the way to the last mile, while also connecting South Korea to MoonPay's global network. As a security partner, BTQ can ensure that this technology stack is quantum-safe from the very beginning. Combined with our collaboration with South Korean banks and fintech companies, this puts QSSN in a central position regarding the security of South Korea's stablecoin infrastructure."

Wallets, custody systems, and settlement networks rely on public key cryptography to authorize transactions and protect keys. Powerful quantum computers are expected to crack the elliptic curve and RSA schemes currently used by these systems. For digital assets, the risk is direct: once the signature keys are compromised, so are the assets.

The design goal of QSSN is to provide post-quantum protection for transaction signing, key management, and settlement without interfering with the existing user experience or operational processes. BTQ and MoonPay Korea aim to extend this protection to issuers, banks, wallets, and merchants that connect to the system by working at the infrastructure level.
