About Kaia

Kaia launched in August 2024 as a hard fork of Klaytn, retaining chain ID 8217. The former KLAY and FNSA tokens were converted to the unified KAIA token, which pays transaction fees and rewards validators.

Kaia uses a BFT-based proof-of-stake consensus with approximately 1-second block times and immediate finality. It is fully EVM-compatible, so Solidity contracts and standard Ethereum tooling deploy directly, and the project emphasizes integration with messaging-app distribution in Asian markets.
