Kaia

Kaia is an EVM Layer 1 blockchain formed through the merger of Klaytn and Finschia blockchains, originally developed by Kakao and LINE respectively. The platform focuses on bringing Web3 accessibility to hundreds of millions of users across Asia through familiar messaging app integrations.

Key technical features include:

• 1-second block time with immediate finality for near-real-time responsiveness
• EVM equivalence ensuring compatibility with existing Ethereum tools and infrastructure
• Account abstraction and gas fee delegation to simplify user onboarding
• Planned CosmWasm support for enhanced smart contract flexibility
• Cross-chain bridge integrations for seamless interoperability

The platform's unique advantage lies in its direct integration with LINE and KakaoTalk messenger applications, providing instant access to over 250 million potential users. This integration removes traditional Web3 barriers by allowing users to interact with blockchain applications through familiar messaging interfaces.

Kaia maintains the same Network IDs as Klaytn (Mainnet: 8217, Testnet: 1001) and supports RPC batching with configurable limits up to 3,000 requests. The transition from Klaytn represents a rebrand rather than a new mainnet, ensuring continuity for existing applications and infrastructure.
