The Stack Kaia Builders Ship On

Quicknode is a leading Kaia RPC provider, serving Kaia mainnet and the Kairos testnet over low-latency Ethereum JSON-RPC from 17+ global regions with a 99.99% uptime SLA. You get a private endpoint in seconds, the kaia_ そして klay_ namespaces, the Debug API, full archive, and Streams and Webhooks, on a platform that handles 500B+ requests a month across 80+ chains.

Kaia is an EVM-compatible layer 1 formed by the merger of Klaytn and Finschia, with 1-second finality and around 4,000 real-world TPS. It uses KAIA for gas and supports standard Ethereum tooling. Mainnet runs on chain ID 8217.

Create a free Quicknode account, select Kaia, and a private RPC URL is generated instantly. You get both HTTPS and WSS endpoints with full method coverage and rate limits that scale with your plan. No credit card is required for the free tier.

A Kaia node syncs the network and serves JSON-RPC requests. Running one means managing hardware, client upgrades, storage, and archive retention. A managed Quicknode Kaia endpoint provides the same RPC interface without requiring your team to operate the node.

Quicknode supports Ethereum JSON-RPC, the Debug API, and the kaia_* そして klay_* namespaces on Kaia. Standard eth_* methods, WSS, Streams, and Webhooks are available through the same endpoint.

Yes. Quicknode runs full archive nodes for Kaia with no pruning, plus the Debug API for debug_traceTransaction そして debug_traceBlockByNumber. インデックス作成、シミュレーション、分析のために、過去の状態を照会したり、トランザクションを追跡したりすることができます。

Yes. The Kaia VM is fully EVM compatible. Deploy existing Solidity contracts with Hardhat, Foundry, or Remix without modification, and use ethers.js, web3.js, viem, and @quicknode/sdk against your Quicknode endpoint exactly as you would on Ethereum.

Quicknode supports Kaia mainnet with chain ID 8217 and the Kairos testnet with chain ID 1001. Both use KAIA as the native gas token.

Quicknode serves Kaia from a global edge network that routes each request to the nearest node, backed by a 99.99% uptime SLA. The JSON-RPC, Debug, and archive endpoints run on the same low-latency infrastructure that handles 500B+ requests a month across 80+ chains.

Yes, there is a free tier. You can create a Kaia endpoint with no credit card and start building over Ethereum JSON-RPC. Paid plans raise rate limits and throughput, and add archive depth, Streams, and Webhooks, as your app grows.

Kaia mainnet uses chain ID 8217, and the Kairos testnet uses chain ID 1001. Both use KAIA as the native gas token. To add a network to a wallet, use your Quicknode RPC URL, the chain ID, the currency symbol KAIA, and the explorer at kaiascan.io.

Use Quicknode Streams for backfill and real-time blocks, logs, and traces delivered to your datastore, and Webhooks for push notifications on addresses and events. For in-app subscriptions, connect over WSS and use eth_subscribe to receive new blocks and logs the moment they land.

Kaia is built for consumer and enterprise apps at scale: payments and wallets, stablecoin and RWA products, gaming, and DeFi. Kaia connects to the LINE and Kakao messenger ecosystems for large-scale distribution across Asia.
