Kaia RPC & Dedicated Nodes

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.

Kaia RPC Endpoint Features

• Network: Mainnet (chain ID 8217)
• Protocol: EVM JSON-RPC
• Transport: HTTP and WebSocket
• Advanced Access: Archive data and dedicated nodes available
• Regions: N. Virginia (additional regions on request)

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.

Getting Started

1. Create or sign in to your OnFinality account.
2. Select Kaia from the supported networks list.
3. Create an API endpoint or deploy a dedicated node.
4. Test your endpoint using eth_blockNumber.
5. Monitor request usage, errors, and limits before moving critical traffic.

OnFinality's infrastructure is designed for production workloads, giving you the reliability and observability needed to build with confidence on Kaia.

Kaia RPC and developer resources

A useful Kaia RPC page should make the connection path, supported capabilities, and production planning trade-offs clear before a developer opens the dashboard.

Best fit: mainnet production workflows for wallet flows, contract apps, and live backends.

What builders usually check first:

• Read current chain state for apps, dashboards, wallets, and backend services.
• Submit transactions and monitor confirmations from Ethereum-compatible tools.
• Query logs, receipts, and historical state when indexers or analytics pipelines need more than the latest block.
• Debug contract behaviour with trace data where the network supports it.

Supported capability notes:

• Authenticated Kaia RPC/API access for wallet flows, contract apps, and live backends.
• Flexible HTTP and WebSocket access for app, backend, and integration workflows.
• Archive-capable workflows when the product needs older chain state.
• Managed node options for workloads that outgrow shared endpoint access.

Decision notes:

• Environment: mainnet. Protocol family: EVM JSON-RPC.
• Flexible HTTP and WebSocket access is listed for supported app and backend workflows.
• Archive support is available for historical state or older chain-data queries.
• Dedicated node options are available when the workload needs isolated resources or more operational control.
• Available regions listed by the network spec include N.Virginia.

A quick connection check usually starts with eth_blockNumber, then moves into the exact methods your wallet, dashboard, bot, indexer, or backend service needs.

Planning the next step:

• Shared RPC is usually enough for early integration, prototypes, and moderate app traffic.
• Consider dedicated nodes when traffic becomes sustained, workloads are latency-sensitive, or isolation and monitoring become operational requirements.
