BTQ Technologies has signed a three-year commercial agreement with Kaia DLT Foundation to deploy its Quantum Secure Stablecoin Network across the Kaia blockchain, marking the first recurring commercial deployment of the security platform.
The agreement is designed to bring post-quantum protection to Kaia’s transaction and settlement infrastructure, with LINE NEXT’s Unifi Wallet positioned among the first consumer applications to benefit. QSSN is intended to protect stablecoins at the account level, allowing security measures to extend across applications using the underlying blockchain infrastructure.
The deployment moves QSSN from earlier pilot projects into a recurring commercial model, with BTQ receiving a share of transaction fees generated by activity secured through the network.
Security at the Blockchain Infrastructure Layer
Under the agreement, BTQ is expected to receive a portion of transaction fees generated by QSSN-secured activity. The company expects first-year revenue to reach six figures in U.S. dollars, while revenue over the three-year agreement will be linked directly to transaction volume.
Rather than relying exclusively on upfront licensing or integration payments, the structure gives BTQ an economic interest in the activity protected by QSSN. As stablecoin use and transaction volumes increase across Kaia, Unifi and other applications, BTQ’s revenue could grow alongside that activity.
The agreement therefore combines a commercial and distribution strategy for QSSN. The technology will operate at the infrastructure layer, allowing protection to extend across applications built on Kaia rather than requiring each individual application to implement a separate security solution.
Kaia Foundation will support deployment at the chain level. BTQ and the foundation plan to introduce quantum-safe protection across transaction and settlement infrastructure serving applications such as Unifi Wallet, stablecoin payments and Mini DApps.
LINE and Kaia Expand Potential Reach
Kaia was created through the merger of Kakao’s Klaytn and LINE Tech Plus’s Finschia blockchains. The resulting Ethereum Virtual Machine-compatible network is connected to KakaoTalk and LINE, providing access to a potential user base of more than 250 million people across several Asian markets.
The network has one-second block times and reported throughput of up to 4,000 transactions per second. Kaia deployed native USDT in May 2025 and is exploring infrastructure for Korean won- and Japanese yen-backed stablecoins as regulatory frameworks develop in South Korea and Japan.
Unifi, developed by LINE NEXT, is a non-custodial stablecoin wallet available directly through LINE Messenger. It supports wallet creation through social login, deposits, payments, transfers, rewards, fiat conversion, and remittances. The wallet already supports stablecoins including USDT, Japan’s JPYC and Indonesia’s IDRP.
Because QSSN operates at the account level on Kaia, stablecoins held through Unifi can receive the protection without requiring changes to the wallet product or direct involvement from individual stablecoin issuers.

Preparing Blockchain Infrastructure for Quantum Threats
BTQ’s technology is designed to address potential risks associated with advances in quantum computing. Digital wallets and blockchain networks increasingly support payments, stablecoins, tokenized assets, identity services, and other applications, increasing the importance of protecting cryptographic systems that control transactions and long-lived digital assets.
QSSN is designed to introduce post-quantum protection at the transaction and settlement layers while minimizing disruption to existing user experiences and operational processes. The approach could allow infrastructure providers to strengthen security across multiple applications through a shared layer.
The Kaia agreement builds on BTQ’s earlier work in South Korea, including a proof of concept involving Finger and iM Bank. That project was described as the country’s first bank-led Korean won stablecoin infrastructure initiative incorporating post-quantum cryptography. BTQ has also identified Finger as an early participant in its QSSN pilot program.
The company said the Kaia deployment provides a commercial reference point for expanding QSSN to additional wallets, stablecoin issuers and payment networks across Asia. As stablecoin adoption develops in the region, the transaction-based model could provide BTQ with an ongoing revenue stream tied to the activity its technology secures.
The agreement gives BTQ a pathway to scale post-quantum security across consumer wallets, stablecoin payments, and blockchain settlement infrastructure while aligning its commercial returns with the growth of secured transaction activity.
