Klaytn (Ground X)
Kaia (formerly Klaytn) is a South Korean blockchain built into KakaoTalk and LINE messaging apps.
The call
Kaia still has Kakao and LINE's reach, but its won stablecoin has slipped again and rivals already have Korean bank deployments live.
Kaia is a blockchain network owned by the companies behind KakaoTalk and LINE Messenger, which together reach hundreds of millions of people in Asia. The company's main plan is to create a Korean won stablecoin (digital money backed by the won), but it has already been delayed from early 2026 to mid-2027, while Avalanche already launched a competing won coin with a real Korean bank in September 2025. Kaia's actual usage has collapsed by 88 percent in nine months and the parent companies appear divided, so the advantage of being inside popular messaging apps has not yet turned into real market power. What matters most is whether new Korean laws arrive in 2026 and which blockchain the Korean banks actually choose to build their stablecoin on in the next year, which will show whether Kaia's connections are real or just a broken promise.
Why
01
AI pressure: None apparent. Kaia is blockchain infrastructure, not an AI product; no AI agent or model directly displaces its function. Could AI do the core job? Unlikely.
02
Bigger players: Avalanche (KRW1 stablecoin with Woori Bank), also Solana and TON. Avalanche's KRW1 stablecoin is live with Woori Bank while Kaia's own won stablecoin slipped from Q1 2026 to H1 2027. Could a giant copy it? Probably.
03
What protects it. Embedded distribution inside KakaoTalk and LINE reaches hundreds of millions of users, though usage on Kaia itself is collapsing.
What would change this call
Whether Kaia's KRW stablecoin ships with a top-3 Korean bank before H1 2027. Shows whether Kaia's core monetization bet converts from roadmap to shipped product.
Kaia DeFi TVL trend over the next two quarters from its ~$12.5M level. Shows whether usage is stabilizing or continuing its 88% collapse.
Whether Kakao or LY Corp formally reduce Kaia governance-council participation. Would confirm parent-company disengagement from the Kaia project.
Kaia DeFi TVL trend over the next two quarters from its ~$12.5M level. Shows whether usage is stabilizing or continuing its 88% collapse.
Whether Kakao or LY Corp formally reduce Kaia governance-council participation. Would confirm parent-company disengagement from the Kaia project.

Questions people ask
- Does Klaytn still exist as a company?
- Not as a standalone brand. Klaytn merged with LINE's Finschia blockchain on August 29, 2024 to form Kaia, run by the Kaia DLT Foundation in Abu Dhabi. Original developer Ground X still exists and became a 100% Kakao subsidiary again on October 22, 2025 for KRW 13.64 billion.
- Who owns Kaia (formerly Klaytn)?
- Kaia is governed by the nonprofit Kaia DLT Foundation plus a Governance Council of about 37 corporate partners including Kakao, Kakao Pay, LY Corp and Binance, as of March 21, 2026. Ground X, the original Klaytn builder, is a 100% Kakao subsidiary since October 22, 2025.
- Is Kaia's token (KAIA) profitable or growing?
- No. KAIA traded near $0.030 as of July 25, 2026, down about 93% from its December 2024 all-time high of $0.41, with market cap around $175-190M (rank roughly #172-179), per CoinGecko.
- What is Kaia's biggest competitor?
- Avalanche shipped a live KRW-pegged stablecoin (KRW1) with Woori Bank in September 2025, beating Kaia to market; Kaia's own won stablecoin has slipped from Q1 2026 to H1 2027 as of May 6, 2026 reporting.
- Is Kaia losing traction in DeFi?
- Yes. Kaia's DeFi total value locked fell from about $104.4M in August 2025 to roughly $12.5M by May 6, 2026, an 88% decline, while Solana's stablecoin cap alone reached $15.1B in the same period, per bloomingbit.io.
- Is joining Kaia/Ground X a safe career move right now?
- Mixed. Kaia has embedded distribution via KakaoTalk and LINE Messenger, but faces an 88% TVL drop, a 93% token decline from ATH, a stablecoin launch delayed to H1 2027, and Korean press describing a 'Line, Kakao split' as of March 21, 2026.
