BTQ Technologies Partners With MoonPay Korea for Post-Quantum Stablecoin Security

AI disclosure: drafted by Basis Desk's AI newsroom and machine-checked against the primary sources listed below — how we use AI. Originally published on Basis Desk.

The quantum tech firm will secure MoonPay Korea's won-backed stablecoin infrastructure and run a banking proof of concept.

Key points

• BTQ Technologies will integrate post-quantum cryptography into MoonPay Korea's won-denominated stablecoin infrastructure [1].
• The firms will conduct a proof of concept with Korean banks using BTQ's Quantum Secure Stablecoin Network (QSSN) [1].
• Woori Bank serves as the inaugural member of MoonPay Korea's KRW Stablecoin Consortium [1].

BTQ Technologies announced on Oct. 9, 2026, that it has been selected as the security partner for MoonPay Korea's digital asset infrastructure [1]. Under the agreement, BTQ will deploy post-quantum cryptography across MoonPay Korea's stack for won-backed stablecoins, encompassing token issuance, distribution, self-custody wallets, currency conversion, settlement, and last-mile merchant delivery [1].

As part of the deployment, the two companies will create a post-quantum security roadmap and conduct a proof of concept with South Korean banking institutions [1]. The trial will test BTQ's Quantum Secure Stablecoin Network (QSSN) for quantum-resistant transaction signing and key management across institutional wallet and settlement pipelines [1]. MoonPay Korea links Korean won stablecoins directly to MoonPay's broader international infrastructure, which serves more than 35 million users in approximately 180 countries alongside over 1,500 enterprise clients [1].

Korean Banking Ties and Quantum Transition

The initiative comes as South Korea transitions from exploratory bank-led stablecoin pilots toward retail merchant acceptance and cross-border settlement under an evolving regulatory framework [1]. Woori Bank, South Korea's oldest commercial bank, currently serves as the inaugural member of MoonPay Korea's KRW Stablecoin Consortium [1].

Public-key cryptography schemes such as RSA and elliptic-curve cryptography—which secure contemporary digital asset wallets and settlement channels—face structural vulnerabilities from potential future quantum computing advances [1]. The partnership integrates post-quantum protections at the foundational infrastructure level rather than retrofitting operational protocols [1]. This collaboration builds on BTQ's prior deployment of QSSN with Finger Inc. and iM Bank on the Kaia mainnet, as well as an integration pact across the Kaia ecosystem with LINE NEXT [1].
