Kaia is the native cryptocurrency and utility token of the Kaia blockchain, a high-performance Layer 1 public blockchain. Launched officially on 29 August 2024, Kaia was formed through the merger of two major Asian blockchain projects: Finschia (by LINE) and Klaytn (by Kakao). KAIA is used to pay transaction fees, execute smart contracts, and incentivise network participants.
Kaia distinguishes itself with unique features such as EVM compatibility, rapid transaction speeds (4,000 TPS), 1-second finality, low gas fees (approximately one-tenth of Ethereum), and a modular three-layer network architecture designed for scalability and enterprise-grade reliability. Its overarching goal is to accelerate blockchain mass adoption by offering a scalable, interoperable, and efficient platform suited for both consumer and enterprise use.
Kaia operates as a Layer 1 EVM-compatible blockchain, integrating the strengths of Finschia and Klaytn. Its modular architecture consists of:
The Kaia Virtual Machine (KVM) ensures compatibility with Ethereum, enabling smooth migration of Ethereum-based smart contracts and secure cross-chain operations.
Kaia employs a modified Istanbul Byzantine Fault Tolerance (IBFT) consensus mechanism, enhanced with Verifiable Random Function (VRF)-based randomness and committee-based validator selection. This setup allows for 1-second block generation and instant finality.
Kaia supports smart contract deployment via its EVM-compatible KVM, enabling developers to port existing Ethereum dApps or build new decentralised applications on the Kaia network.

The Kaia Foundation has partnered with CARV to bolster identity and data privacy infrastructure. Integration with Dune Analytics supports ecosystem data visibility. Leveraging the established user bases of Kakao and LINE, Kaia focuses on driving mass adoption, particularly in East Asia.
Kaia emerged from the merger of two established blockchains: Finschia (launched by LINE in 2018) and Klaytn (developed by Kakao’s Ground X in 2019). The unification combined their technologies, communities, and governance models, culminating in the Kaia mainnet launch on 29 August 2024.
The formation of Kaia through the merger represents its most significant development to date. No major forks have occurred since its inception.
Kaia has developed into a high-throughput, low-fee, enterprise-ready blockchain. Its ecosystem now includes a growing range of DeFi, NFT, and real-world asset projects. As of June 2025, KAIA has a circulating supply near 6 billion tokens, with a market capitalisation exceeding $500 million.
