BTQ Technologies has been selected to provide quantum-resistant security infrastructure for South Korea’s first bank-led Korean Won stablecoin proof-of-concept, deploying on the Kaia mainnet through iM Bank’s initiative. The move marks a significant step toward domestic stablecoin issuance in a market that banned KRW-backed tokens for nine years and has seen $40 billion flow into foreign dollar-backed alternatives in Q1 2025 alone.
Nine-Year Ban Creates Institutional Urgency
South Korea prohibited domestic KRW stablecoin issuance since approximately 2015, creating a regulatory vacuum that pushed capital toward offshore dollar-backed stablecoins. The anticipated Digital Asset Basic Act, expected to move through the legislative process in 2026, would authorize the first domestic KRW-backed tokens. This regulatory shift has accelerated institutional interest in stablecoin infrastructure. iM Bank’s decision to lead a proof-of-concept signals major Korean financial institutions are preparing for imminent authorization. The $40 billion outflow from South Korean exchanges into foreign stablecoins in the first quarter of 2025 underscores the market demand for a domestic alternative.
BTQ’s Quantum Security Deployment on Kaia
BTQ Technologies will deploy its QSSN (Quantum-Safe Security Network) on Kaia, a Layer-1 blockchain engineered specifically for institutional settlement. Kaia offers 1-second block times and instant finality, critical for stablecoin infrastructure. The QSSN framework uses ML-DSA post-quantum cryptography integrated within the ERC-4337 account abstraction standard, protecting against future quantum computing threats. BTQ has prior deployment experience through partnerships with Danal, a major South Korean mobile carrier billing provider, and Finger Inc. Group, a banking-solutions developer. These implementations demonstrate the technology’s readiness for institutional deployment in the Korean financial ecosystem.
Multi-Chain Competition and Regulatory Momentum
South Korea’s stablecoin development is not limited to Kaia. Competing Tier-1 Korean banks are conducting parallel proof-of-concepts on alternative blockchains including Solana, Avalanche, and GIWA Chain, creating a competitive landscape for institutional adoption. This multi-chain approach reflects both regulatory uncertainty and institutional hedging. The anticipated 2026 passage of the Digital Asset Basic Act would resolve much of that uncertainty and accelerate which chains become preferred settlement layers for KRW stablecoins. BTQ’s selection by iM Bank positions it as the quantum-security standard-bearer in this regulatory transition period.
Timeline to Market Authorization Remains Fluid
No specific launch date for the iM Bank proof-of-concept has been announced. The Digital Asset Basic Act’s anticipated 2026 legislative timeline is not yet confirmed. Success of this PoC could influence which blockchains and security frameworks regulators endorse for production KRW stablecoin issuance. The quantum security layer adds a differentiator in a crowded infrastructure market, but adoption ultimately depends on regulatory approval and institutional adoption patterns once authorization occurs.
