Kaia is a high-performance Layer-1 blockchain formed through the merger of Klaytn and Finschia, originally developed by Kakao and LINE. Designed to bring Web3 to hundreds of millions across Asia, Kaia uses an optimized Istanbul BFT consensus mechanism and is fully EVM-compatible, supporting standard Ethereum JSON-RPC methods. This makes it easy for developers to deploy existing Solidity contracts and use familiar tools like Hardhat, Foundry, and Web3.js.

Why Use OnFinality for Kaia RPC?

Running your own Kaia Endpoint Node (EN) requires significant technical expertise, monitoring, and computing resources. OnFinality eliminates this overhead by providing managed Kaia RPC endpoints and dedicated node infrastructure. Whether you are building a DeFi protocol, a wallet, an NFT marketplace, or a backend service, OnFinality offers authenticated access with clearer usage limits, request analytics, and a path to scale.

When to Choose Dedicated Nodes

For teams with high throughput requirements, predictable workloads, or the need for isolated infrastructure, OnFinality offers dedicated Kaia nodes. Dedicated nodes provide exclusive access to a node instance, eliminating contention and offering full control over configuration and resource allocation.
