What Is Kaia (KAIA)? The Layer 1 Blockchain That Merged Klaytn and Finschia

Kaia (KAIA) is the Layer 1 blockchain formed when Klaytn and Finschia merged in August 2024, and its native coin jumped 62.60% in a single day in early October 2026. The chain runs Ethereum-compatible smart contracts on one-second blocks, and KAIA pays its gas fees and secures the network through staking.

The jump came on the day a new listing on South Korean won markets opened, and traders piled in behind it. CoinMarketCap recorded $318.7 million of KAIA trading that day, 1.62 times the volume of the previous 30 days combined.

What Is Kaia Crypto?

Kaia is the network that Kakao's Klaytn and LINE's Finschia became. The two foundations merged their chains into a single Layer 1, and the Kaia mainnet went live on 29 August 2024 after the Kaia DLT Foundation incorporated in Abu Dhabi Global Market. The foundation runs the chain as a non-profit, independent of both founding companies.

Holders of the old coins didn't get the same deal. KLAY needed no swap at all, since the coin kept trading under its old ticker at launch and venues renamed it KAIA on their own schedules. Finschia's FNSA went through a one-year swap window that opened with the mainnet, and Kaia's blog set the conversion at roughly 148 KAIA for each FNSA.

Phemex's 2021 explainer on Klaytn's push toward mass adoption covers the Kakao chain as it stood before the merger.

Kaia pitches itself as an EVM-compatible Layer 1 built for stablecoin settlement and onchain finance across Asia. Its developer docs carry a full section on a Korean won stablecoin, and that plan is the business case behind the coin.

Why Is Kaia Trending?

Kaia is trending because of that listing-day jump, which came on the heaviest volume since two days in early December 2024. Since the August 2024 merger, only those two days rank above it on CoinMarketCap.

A market-wide rally would have lifted everything, and it didn't. Bitcoin gained 1.08% that day, and across the 135 contracts on Phemex's board the median rose 1.13% while Cosmos (ATOM) led at 17.20%. KAIA's gain came to 3.6 times that best move, which points to buying aimed at Kaia itself.

Volume is the tell on a day like this, because a price move on heavy turnover carries more information than one on thin trading. Phemex's guide to crypto trading volume and how it affects price shows you how to read it.

How Does Kaia Work?

The Kaia blockchain runs an optimized version of Istanbul BFT, a Byzantine fault tolerant consensus in which a committee drawn from the Governance Council proposes and signs each block. A verifiable random function picks that committee for every block. Kaia's consensus documentation lists one-second block generation and immediate finality, with capacity for 4,000 transactions per second, so a confirmed transfer can't be undone by a chain reorganization.

The validators are companies. Each Governance Council member runs a Core Cell and must stake at least 5 million KAIA, and KaiaScan's block feed shows members such as LINE NEXT and the game publisher Netmarble proposing blocks. Phemex's primer on who blockchain validators are explains the job in general terms.

Developers write contracts in Solidity, and Kaia's docs promise full Ethereum compatibility, so Ethereum wallets and tools connect with little change.

LINE gives Kaia its distribution. Mini Dapps launched inside LINE Messenger on 22 January 2025 with 32 apps, and Kaia's blog reported over 35 million cumulative users in the first month. The apps open inside the messenger or on the Dapp Portal website, so a LINE user can try one without installing a separate crypto app.

KAIA Tokenomics

KAIA is the chain's native coin, so its supply lives in the protocol itself. KaiaScan counted about 6.44 billion KAIA in circulation in early October 2026, and new coins enter only through block rewards that the Kaia governance process sets.

Is There a Kaia Token Contract Address?

No. KAIA works the way ether does on Ethereum, as a native coin with no token contract, so there is no Kaia token contract address to paste into a wallet. Without a contract there is no mint or freeze key to audit either. A token calling itself KAIA on another chain is a bridged copy or a different project, and CoinGecko lists Illusive AI under the same ticker.

How Many KAIA Are Minted?

The token economy docs set the rule at 9.6 KAIA minted for every block, about 300 million a year, or what the docs call 5.2% annual inflation. The docs add that governance can change the rate. Each block reward splits four ways.

Fees push the other way, but only a little. Kaia's transaction fee docs say the chain has burned half of each block's gas fee since the Magma hard fork, and most of it since the later Kore upgrade. KaiaScan's counter puts fee burns at about 7.20 million KAIA in total, a sliver of a single year's minting.

KaiaScan's headline burn figure reads about 5.58 billion KAIA, but 5.30 billion of that came from a one-off treasury rebalance under KIP-103. Phemex's explainer on what it means to burn crypto covers how both kinds of burn work.

Who Holds KAIA?

KaiaScan's top-accounts list in early October 2026 shows the ten largest wallets holding 65.15% of supply. Four are Governance Council staking contracts that lock coins to run the network, while two belong to exchanges and hold about a fifth of everything.

How to Buy KAIA Safely

Phemex delisted its KAIA pairs, so these steps cover buying the coin on a venue that lists it and holding it yourself.

1. Set up a self-custody wallet that supports Kaia mainnet. Kaia is EVM-compatible, so an Ethereum-style wallet can add the network with the settings in Kaia's docs.

2. Buy native KAIA on the Kaia network and skip the copies. Native KAIA has no contract address, so a venue or swap that asks you to pick a "KAIA" token by contract is showing you a bridged copy or a namesake.

3. Check the coins that share or resemble the KAIA ticker. Illusive AI trades as KAIA on CoinGecko and KAIO is a separate real-world-asset token. KardiaChain uses KAI, and CoinMarketCap's legacy Klaytn (KLAY) page tracks the pre-merger coin.

4. Send a small test withdrawal to your own wallet first. Pick the Kaia network, confirm the coins land, then move the rest.

5. Stake through Kaia Square if you want to earn block rewards. Its public delegation feature lets holders delegate KAIA to a validator and collect a share of those rewards.

What Are the Risks of Kaia?

A Handful of Wallets Hold Most of the Supply

Ten wallets control nearly two-thirds of KAIA. The two exchange wallets in that group can send coins to market at any time, so a large transfer out of them is the first thing to watch after a spike like this one.

Issuance Keeps Running

New supply arrives at the docs' fixed rate every second, whatever the price does, and the fee burn doesn't come close to absorbing it. Holders who don't stake see their share of supply shrink with every block.

Thin Trading Outside the Listing Day

Before the listing, KAIA averaged about $6.57 million of volume a day across the previous month. If turnover drifts back toward that level, a large order moves the price far more than it did on the listing day.

A Deep Hole Below the Record

Even after the jump, KAIA's early-October close sat 84.98% below its Kaia-era record close from December 2024 on CoinMarketCap. One strong day hasn't repaired a fall of that size, and buyers from late 2024 remain far under water.

Is Kaia Crypto a Good Investment?

Kaia crypto is a bet that the chain becomes a settlement layer for stablecoins in Asia, and the early-October spike didn't test that bet. A listing changes who can buy the coin. It doesn't change how much the network earns in fees.

What would have to be true is visible on-chain. Fee burns would need to grow toward the size of yearly issuance, and stablecoin transfers would need to fill blocks that average only a handful of transactions each.

The figures above describe a coin that trades on access and flows. Most of the supply sits with council members and two exchange wallets, and the burn is small next to minting. A buyer betting on stablecoin settlement is buying a plan with little fee data behind it so far.

Phemex's guide to stablecoin types and trading covers the assets Kaia wants to carry, which is the market that decides the coin's case.

Frequently Asked Questions

What is Kaia blockchain?

Kaia is an EVM-compatible Layer 1 created by merging Kakao's Klaytn with LINE's Finschia, and its mainnet has run since 29 August 2024. It finalizes a block every second, and its native coin KAIA pays for gas and backs the validators' stake.

How do you buy Kaia coin?

Set up a self-custody wallet that supports Kaia mainnet, buy native KAIA on a venue that lists it, and withdraw it on the Kaia network after a small test. Native KAIA has no contract address, so a token that asks for one is a copy.

Where can you buy Kaia crypto?

Phemex delisted its KAIA pairs, so you need a venue that lists the native coin with deposits and withdrawals on the Kaia network. Same-ticker tokens such as Illusive AI are different projects.

Is KAIA the same as KLAY?

Yes, in practice, because Klaytn's KLAY became KAIA one for one at the August 2024 merger without a swap. Finschia holders converted FNSA at about 148 KAIA each. CoinMarketCap keeps a separate legacy page for the pre-merger KLAY history.

Bottom Line

Kaia's early-October spike priced access, and access arrives once. A new pool of buyers got the coin in a single day, but the chain's case rests on something slower, stablecoin payments generating enough fees to burn a meaningful share of the 9.6 KAIA minted every block. Until that burn starts to bite, KAIA trades on listings and flows, and the holder table says those flows run through a few wallets.
