What is the best Kaia RPC provider?

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_` and `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.

How do I get a Kaia RPC URL?

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.

What is a Kaia node and do I need to run one?

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.

What Kaia APIs and RPC methods does Quicknode support?

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

Does Quicknode support Kaia archive data?

Yes. Quicknode runs full archive nodes for Kaia with no pruning, plus the Debug API for `debug_traceTransaction` and `debug_traceBlockByNumber`. You can query historical state and trace transactions for indexing, simulation, and analytics.

Is Kaia EVM compatible?

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.

Which Kaia networks does Quicknode support?

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

How fast and reliable is Quicknode's Kaia RPC?

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.

How much does Kaia RPC cost, and is there a free tier?

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.

What is the Kaia chain ID?

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.

How do I stream real-time Kaia data?

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.

What can you build on Kaia?

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.

Kaia JSON-RPC

Standard JSON-RPC over HTTPS and WSS on Kaia mainnet and the Kairos testnet. Every EVM method supported, including eth_call, eth_getLogs, eth_getBalance, eth_sendRawTransaction, and eth_subscribe, with predictable rate limits.

// Built for EVM Developers

Your Ethereum app runs on Kaia.

Kaia is an EVM-compatible layer 1, so the tooling you already know works unchanged. ethers.js, web3.js, viem, and web3.py all hit a Quicknode Kaia endpoint the same way they hit Ethereum. Same methods, same SDK, just a different RPC URL.

Keine Überarbeitungen

Point your existing Ethereum codebase at a Quicknode Kaia endpoint and deploy. Contracts, libraries, and tooling carry over.

Dieselben JSON-RPC-Methoden

eth_call, eth_getLogs, eth_sendRawTransaction und eth_subscribe verhalten sich alle genau so wie auf Ethereum.

// Add Kaia to MetaMask

Connect MetaMask to Kaia in seconds.

Open MetaMask, go to Settings, Networks, Add Network, and enter your Quicknode Kaia RPC URL with the details on the right. Save, and MetaMask routes through your private Quicknode endpoint instead of a rate-limited public RPC.
