Kaia RPC Endpoint and API
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.

Build faster with Kaia RPC endpoints
Use OnFinality's Kaia RPC APIs to connect wallets, dApps, dashboards, bots, and backend services without operating your own node from day one.
Public endpoint testing
Start with the Kaia public RPC endpoint for lightweight checks, prototypes, and quick integration tests.
Authenticated API access
Move production traffic to authenticated endpoints when you need clearer limits, analytics, and operational visibility.
Standard RPC methods
Query Kaia blocks, transactions, balances, events, and chain state through HTTP and WebSocket workflows.
Operate Kaia infrastructure with more control
Production teams need more than an endpoint URL. They need observability, predictable capacity, and a path from shared RPC access to isolated infrastructure.
Request visibility
Track usage patterns and response activity so your team can understand traffic growth before it becomes an incident.
Dedicated node path
Use dedicated Kaia nodes when your workload needs isolated resources, custom operations, or stronger capacity planning.
Archive and historical data
Plan for archive access when analytics, audits, indexers, or advanced app features need older Kaia state.
Choose the right Kaia RPC setup
Different Kaia products need different infrastructure. OnFinality gives teams a practical path from public RPC testing to production-grade API and node operations.
For prototypes
Use public RPC for simple reads, connection checks, and early experiments where strict performance guarantees are not required.
For live apps
Use authenticated API endpoints when users depend on stable request handling, monitoring, and scalable access.
For heavy workloads
Use dedicated nodes for sustained traffic, latency-sensitive services, validator tooling, exchange systems, and indexing pipelines.
