BTQ Technologies has entered a three-year commercial agreement with the Kaia DLT Foundation to roll out its Quantum Secure Stablecoin Network (QSSN) across the Kaia blockchain, marking the security platform's first recurring commercial deployment. The deal 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.

Unlike the pilot projects that preceded it, the agreement establishes a recurring commercial model: BTQ will receive a share of the transaction fees generated by activity secured through the network. QSSN is intended to protect stablecoins at the account level, allowing security measures to extend across applications built on the underlying blockchain infrastructure.

Security Applied at the Infrastructure Layer

Under the agreement, BTQ is expected to receive a portion of transaction fees generated by QSSN-secured activity. The company anticipates first-year revenue in the six figures in U.S. dollars, with revenue over the three-year term tied directly to transaction volume.

Rather than relying exclusively on upfront licensing or integration payments, the structure gives BTQ an economic interest in the activity its technology protects. As stablecoin use and transaction volumes increase across Kaia, Unifi and other applications, BTQ's revenue could grow alongside that activity, making the agreement both a commercial and distribution strategy for QSSN.

Because the technology operates at the infrastructure layer, protection can extend across applications built on Kaia without each individual application implementing a separate security solution. The Kaia DLT Foundation will support deployment at the chain level, and the two parties plan to introduce quantum-safe protection across transaction and settlement infrastructure serving applications such as Unifi Wallet, stablecoin payments and Mini DApps.

Kaia and LINE Extend the 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 chain features 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 via social login, along with 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 protection without requiring changes to the wallet product or direct involvement from individual stable issuers.

Preparing Blockchain Infrastructure for Quantum Threats

BTQ's technology is designed to address potential risks associated with advances in quantum computing. Much of that concern centers on the public-key cryptography securing most blockchains today, which is considered vulnerable to sufficiently capable quantum machines, and on "harvest now, decrypt later" scenarios in which encrypted data recorded now could be unlocked once such hardware matures. Standards efforts are already responding: the U.S. National Institute of Standards and Technology finalized its first post-quantum cryptography standards in 2024, giving network operators a reference point as they weigh migration.

As digital wallets and blockchain networks increasingly support payments, stablecoins, tokenized assets, identity services and other applications, protecting the cryptographic systems that control transactions and long-lived digital assets becomes more important.

QSSN is designed to introduce post-quantum protection at the transaction and settlement layers while minimizing disruption to existing user experiences and operational processes, an approach that 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, and BTQ has 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. Practical markers of that expansion will be the pace of QSSN-secured transaction volume on Kaia and whether additional wallets, issuers and payment networks build on the deployment in line with BTQ's stated plan. 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, giving the company 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.
