KAIA is a layer-1 blockchain that was launched on 29th August 2024 through the merger of Klaytn (KLAY), a project backed by Kakao — South Korea's dominant messaging and internet conglomerate — and Finschia (FNSA), developed by Line Tech Plus, an affiliate of Naver, Kakao's principal rival. The Kaia DLT Foundation was established in Abu Dhabi, signalling the project's aspirations beyond the Korean market. Built as an Ethereum Virtual Machine (EVM)-compatible public chain, KAIA has staked its future on stablecoin payments, real-world asset (RWA) tokenisation, and on-chain financial infrastructure.
Origin story
KAIA was born from what many in the industry have called the first proper merger in the history of crypto — a transaction dramatic enough to warrant the portmanteau "Naver-Kakao coin", or "Ne-Ka-O coin" in Korean shorthand.
Klaytn was created in 2019 by Ground X, a subsidiary of Kakao. It established itself as Korea's leading layer-1 blockchain and earned institutional credibility by being selected as the preferred partner for the Bank of Korea's central bank digital currency (CBDC) pilot programme. Finschia was built by Line Tech Plus to serve markets where Line messenger has a strong foothold — Japan, Taiwan, Indonesia, and Thailand.
When the merger of these two projects was announced in February 2024, it immediately electrified the market. South Korea's two internet giants were pooling their blockchain ventures into a single entity. After six months of integration work, KAIA officially launched on 29th August 2024. The conversion ratio was set at one Klaytn token to one KAIA, and one Finschia token to 148 KAIA. The combined project carried an anticipated market capitalisation of around 1.5 trillion Korean won (approximately $1.1 billion), making it the largest domestically-bred crypto project in Korean history. The decision to base the foundation in Abu Dhabi was a deliberate statement of intent: this was to be a global blockchain, not merely a Korean one.
What does KAIA actually do?
KAIA is an EVM-compatible layer-1 blockchain. Its compatibility with Ethereum means that decentralised applications and smart contracts built for Ethereum can be ported across with minimal friction, lowering the barrier to entry for developers. Three technical characteristics stand out: block generation and confirmation in under one second; a throughput of 4,000 transactions per second; and transaction fees roughly one-tenth of those on Ethereum.
The project's central strategic asset, however, is neither technical nor financial — it is social. KakaoTalk has around 50 million users in South Korea, while Line counts roughly 200 million users across Asia. By embedding KAIA directly into these messaging platforms, the project aims to bring blockchain into everyday life. Users would be able to send and receive digital assets within KakaoTalk or Line itself, with no need for a separate crypto wallet application.
On the commercial side, the focus is squarely on stablecoins, RWA tokenisation, and payment infrastructure. KB Kookmin Bank, one of South Korea's largest lenders, completed a proof-of-concept (PoC) in May 2026 for Korean-won stablecoin payments — both offline transactions and international remittances — built on the KAIA blockchain. iM Bank (formerly Daegu Bank) has also conducted a won-denominated stablecoin PoC on KAIA's mainnet. Partnerships with GCash, the Philippines' largest mobile payments platform, and with Tether (USDT), the world's dominant stablecoin issuer, further underline the project's ambitions to connect Southeast Asia's fragmented payments landscape through a single blockchain layer.
Progress and problems
The reality since the merger has been harder than the headlines suggested.
The most pressing unresolved issue is KAIA's absence from Upbit, South Korea's largest cryptocurrency exchange by volume. The reason is structural: Kakao remains a significant shareholder in Dunamu, the company that operates Upbit. Under Korean financial regulations governing conflicts of interest, that relationship effectively blocks KAIA's listing on the exchange. Industry observers note that Kakao has been gradually reducing its Dunamu stake, and should that relationship be formally unwound, the prospects for an Upbit listing — and the liquidity boost that would follow — would improve considerably.
Price performance has also disappointed. The token surged on launch-day optimism before entering a prolonged decline. It has since partially recovered, aided by a shift in the domestic policy environment: following the inauguration of President Lee Jae-myung's government in 2025, South Korea adopted a markedly more crypto-friendly regulatory stance, and expectations around the introduction of won-denominated stablecoins gave KAIA's price fresh support.
Assessment
KAIA represents the largest consolidation experiment in Korean blockchain history. The backing of two of Asia's most widely-used digital platforms is a genuine competitive advantage. Yet both Klaytn and Finschia carried the weight of underwhelming track records into the merger. Combining two projects does not automatically dissolve the limitations each brought to the table.
The strategic direction — stablecoins, payments infrastructure, and Southeast Asian financial connectivity — is coherent. The partnerships with KB Kookmin Bank, GCash, and Tether are substantive rather than merely cosmetic. If KAIA secures its Upbit listing and delivers meaningful, visible integration with KakaoTalk and Line, the project's narrative could shift decisively. If that integration stalls, however, KAIA risks becoming another chapter in a long history of Korean crypto projects that promised more than they delivered.
For now, KAIA sits squarely in the space between genuine potential and genuine uncertainty.
