Why Kaia, Why Now

Korea is at the center of a stablecoin revolution. As Chairman of Kaia Dr. Sam Seo noted in a recent BeInCrypto article:

“Japan, Korea, Hong Kong, China, and the Philippines are more focused on their currency-based stablecoins because they care about their people and their currency.”

In Korea, major banks like KB Kookmin, Shinhan, Hana, and Woori along with platforms such as Kakao, Naver, and Upbit are preparing KRW-denominated stablecoins across multiple chains. This momentum signals that stablecoins are about to become a mainstream payment and settlement rail in Korea.

We believe Kaia is uniquely positioned as a hub in this movement. With deep ties to Kakao’s ecosystem, including KakaoTalk and Kakao Pay, Kaia will bring stablecoin access closer to everyday consumers. It’s positioned to play a leading role as policy clarifies the path for regulated KRW stablecoins.

Native Kaia Support for Universal Apps

By connecting Kaia into ZetaChain’s Universal Blockchain, we prepare the foundation for a new generation of cross-chain experiences.

Unified Liquidity & Cross-Chain Composability

KRW stablecoins issued on Kaia can seamlessly reach every other major chain supported by ZetaChain, accessible as one canonical asset across Ethereum, Solana, Sui, Bitcoin, and more. Developers can also compose these stablecoins with native BTC, ETH, SOL, SUI, and other assets in a single Universal App, unlocking new DeFi products such as swaps, lending, and yield apps without liquidity fragmentation.

Simplified Development & Seamless UX

Developers deploy once to ZetaChain and instantly gain access to Kaia alongside every other connected ecosystem with no bridges, wrappers, or redeployments required. Universal Apps automatically extend to Kaia while end users enjoy a one-click experience for cross-chain payments, transfers, and stablecoin swaps that “just work” across apps and wallets.

Institutional & AI-Ready

As banks and fintechs roll out KRW stablecoins on Kaia, ZetaChain ensures those assets are usable across chains, supporting adoption in both consumer and institutional payments. With a unified asset model (one KRW coin across chains), AI agents and automated apps can reason about Kaia assets safely and consistently, reducing complexity and enabling more intelligent stablecoin use cases.

Building the Universal Blockchain in Korea

Our push in Korea builds on real partnerships. We recently announced an alliance with MBlock, the blockchain arm of Maeil Business Newspaper (often called the “Financial Times of Korea”), to help secure the Universal Blockchain and expand institutional adoption. We’re also collaborating with Stage Five on telco-adjacent pilots that embed the Universal Blockchain directly into mobile experiences, bringing cross-chain UX closer to everyday users.

Our testnet integration with Kaia is a key part of building the Universal Blockchain in Korea. As the stablecoin economy takes shape, ZetaChain is positioned to make assets like the KRW-pegged stablecoin feel as as simple and unified as cash on the internet.
