Kaia RPC Endpoint

Flat-rate Kaia RPC provider and Kaia RPC node access: free tier, no KYC, HTTP & WebSocket. Kaia mainnet chain ID 8217.

Kaia is an EVM-compatible Layer 1 formed in August 2024 by merging the Klaytn and Finschia blockchains, targeting consumer and enterprise applications across Asia. SwiftNodes provides Kaia mainnet RPC over HTTP and WebSocket.

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.

Common Use Cases on Kaia

• Consumer dApps and mini-apps
• Stablecoin settlement
• DeFi protocols
• NFT and gaming applications
• Enterprise blockchain integrations

Kaia Ecosystem

Inherits the combined Klaytn and Finschia ecosystems, including DeFi, NFT, and gaming projects, with distribution tied to LINE messaging-app integrations across Asia.

ethers.js

import { JsonRpcProvider } from "ethers";

const provider = new JsonRpcProvider(
  "https://rpc.swiftnodes.io/rpc/kaia?key=YOUR_API_KEY"
);

const blockNumber = await provider.getBlockNumber();
console.log("Kaia block:", blockNumber);

viem

import { createPublicClient, http } from "viem";

const client = createPublicClient({
  transport: http("https://rpc.swiftnodes.io/rpc/kaia?key=YOUR_API_KEY"),
});

const blockNumber = await client.getBlockNumber();

web3.py

from web3 import Web3

w3 = Web3(Web3.HTTPProvider("https://rpc.swiftnodes.io/rpc/kaia?key=YOUR_API_KEY"))
print("Kaia block:", w3.eth.block_number)

Kaia guides from the blog

• Kaia RPC: The Merged Klaytn + Finschia Chain, for DevelopersKaia is the EVM Layer 1 formed by merging Klaytn and Finschia — chain ID 8217, ~1s blocks, immediate finality, and a huge Asian user base via LINE and Kakao. It speaks standard eth_* RPC, so viem and ethers just work. Here's what carries over and the Klaytn-heritage features worth knowing.
