BTQ TECHNOLOGIES TO BRING POST-QUANTUM SECURITY TO LINE NEXT'S UNIFI WALLET UNDER COMMERCIAL AGREEMENT WITH KAIA DLT FOUNDATION

BTQ Technologies Corp. has signed a three-year commercial agreement with Kaia DLT Foundation to deploy BTQ's quantum secure stablecoin network across the Kaia blockchain ecosystem. Because QSSN will protect stablecoins at the account level on Kaia, Line Next Inc.'s Unifi wallet, a consumer stablecoin wallet that holds those assets on Kaia, is positioned to be among the first consumer use cases for QSSN on Kaia.

Under the agreement, BTQ will receive a portion of transaction fees generated by QSSN-secured activity, creating a recurring, transaction-based revenue stream for the company. BTQ expects first-year revenue in the six figures (U.S. dollars), with revenue over the three-year term tied directly to transaction volume.

The agreement represents QSSN's first recurring commercial deployment and places BTQ's postquantum security infrastructure within the ecosystem being built by Line Next and Kaia. The significance of the deployment extends beyond the initial revenue contribution: It connects QSSN with established counterparties, consumer-facing products, and a potentially significant base of users and transaction activity.

Rather than generating only a one-time licensing or integration fee, QSSN participates economically in the activity it will protect. As adoption, users and transaction volumes grow across Line Next, Kaia and products including Unifi wallet, BTQ has the opportunity to participate in that growth through its share of transaction fees.

The agreement therefore establishes both a commercial model and a distribution model for QSSN: postquantum security deployed at the infrastructure layer, integrated with major ecosystem counterparties, and monetized through the transactions generated by the users and applications operating on that infrastructure.

Key agreement terms:

• Three-year term;
• BTQ receives a portion of transaction fees from QSSN-secured transactions;
• Growth potential tied to transaction volume;
• Chain-level deployment on Kaia, the blockchain behind Line's Web3 and stablecoin ecosystem, including Unifi wallet, covering transaction and settlement infrastructure.

"This agreement advances BTQ's strategy of making postquantum security part of the infrastructure that digital finance runs on," said Olivier Roussy Newton, chief executive officer of BTQ Technologies. "For BTQ, the significance is both commercial and strategic. It establishes a recurring revenue model for QSSN and brings our technology into the wallet and settlement infrastructure of a major consumer ecosystem. Working with Line Next and Kaia gives us a commercial foundation to expand into additional wallets, stablecoin issuers and payment networks, with revenue tied to the activity we secure."

"Kaia was built as settlement infrastructure for stablecoins across Asia, and infrastructure has to be ready for threats that are years away, not just the ones in front of us today," said Sam Seo, chairman of Kaia DLT Foundation. "Integrating QSSN at the chain level lets us strengthen the security of stablecoin issuance and settlement for every application in the ecosystem at once, rather than asking each one to solve it alone. As KRW, JPY and other local stablecoins come onto Kaia, and as consumer services like Unifi bring them to everyday users, that shared foundation becomes more important, not less."

"Unifi already supports stablecoins from Japan, Indonesia and beyond, and that footprint will keep growing," said Woosuk Kim, chief strategy officer of Line Next. "As more value moves through stablecoins on Kaia, the security of the underlying chain becomes a shared priority for everyone building on it. We expect Kaia's integration of QSSN to give Unifi and its users a stronger, postquantum-ready foundation for that growth, and we look forward to building on it together."

Distribution across the Kaia ecosystem

Kaia Foundation is a party to the agreement to support deployment at the chain layer. BTQ and Kaia Foundation will introduce quantum-safe security across Kaia's transaction and settlement infrastructure, extending protection to applications built on Kaia, including Unifi wallet, stablecoin payments and Mini DApps.

Kaia was formed through the merger of Kakao's Klaytn and Line Tech Plus's Finschia chains. The resulting ethereum-virtual-machine-compatible blockchain is connected to KakaoTalk and Line, two of Asia's largest consumer messaging platforms. Together, the platforms represent a potential user base of more than 250 million people across South Korea, Japan, Thailand, Taiwan, Indonesia and other Asian markets.

Kaia offers one-second block times and throughput of up to 4,000 transactions per second. Native USDT was deployed on Kaia in May, 2025, and the ecosystem is exploring KRW- and JPY-backed stablecoin infrastructure as regulatory frameworks develop in Korea and Japan. The Kaia Wave initiative has attracted more than 700 project applications, with a growing set of consumer applications now live within Line Messenger.

Bringing postquantum security to Line Next's Unifi wallet

Unifi is Line Next's non-custodial wallet dedicated to stablecoins and accessible directly within Line Messenger. It supports wallet creation through social log-in, deposits, payments, transfers, rewards, fiat conversion and remittances. Unifi has on-boarded stablecoins including USDT, Japan's JPYC, and Indonesia's IDRP, and is working to add stablecoins from around the world. Line has approximately 196 million to 200 million monthly active users across Asia who can access Kaia-based services directly within the Line app.

QSSN will protect stablecoins at the account level on Kaia, so USDT, JPYC, IDRP and other Kaia tokens are covered without issuer involvement. Because Unifi users hold those assets on Kaia, adoption can begin at the infrastructure level without changes to the Unifi product, positioning Unifi among the first consumer use cases for QSSN on Kaia.

This distribution footprint gives QSSN access to an ecosystem spanning consumer wallets and the underlying settlement network. Because BTQ's revenue is tied to QSSN-secured transaction activity, the company can benefit as stablecoin usage grows on Kaia and across applications such as Unifi, and as protection extends to the settlement layer serving the broader ecosystem.

Building a recurring revenue business

The agreement builds on QSSN's commercial and technical milestones in Korea. BTQ previously announced that QSSN was selected as the core postquantum cryptography security technology provider for a proof of concept with Finger Inc. and iM Bank. Developed on the Kaia mainnet, the project is South Korea's first bank-led Korean won stablecoin infrastructure incorporating postquantum cryptography.

BTQ also announced that Finger joined Danal as an early participant in the QSSN pilot program. These initiatives expand the company's Korean ecosystem across commercial payments, banking infrastructure, enterprise information technology, hardware-rooted security and regulated digital asset infrastructure.

The agreement connects these initiatives to a deployment designed to generate revenue from live transaction activity. It gives BTQ a major commercial reference and a model for extending QSSN to additional wallet providers, stablecoin issuers and payment networks across Asia.

"Postquantum security needs to be deployed at scale, with economics that support its adoption," said Christopher Tam, president and head of innovation at BTQ Technologies. "Linking our revenue to transaction volume aligns BTQ with Kaia: We grow as QSSN-secured activity grows. This agreement advances QSSN from pilots into a recurring revenue model on infrastructure built for consumer-scale use, and gives us a clear basis for working with more wallets, issuers and settlement networks across the region."

Postquantum security at the transaction layer

Digital wallets are becoming a critical gateway for payments, stablecoins, tokenized assets, identity and blockchain-based consumer applications. As quantum computing advances, the cryptographic assumptions supporting these systems will need to evolve, particularly for long-lived assets, administrative controls, issuer permissions and transaction authority.

QSSN is designed to help infrastructure providers make this transition without disrupting existing user experiences or operational workflows. By placing postquantum protection at the transaction and settlement layers, QSSN is intended to extend security across the infrastructure used by multiple applications.
