What changed on Kaia recently
- The Prague hardfork activated on mainnet on 17 Jul 2025 at block 190,670,000 (Kaia v2.0.2), adding EIP-2537 BLS12-381 precompiles, EIP-2935 historical blockhash, EIP-7610 and gas abstraction. source ↗
- Kaia v2.1.0 (28 Oct 2025, no hardfork) introduced the KIP-249 MEV auction (CNs must expose an 'auction' WebSocket namespace) and enabled LevelDB snappy compression by default, with a ~10 hour compaction for existing mainnet data. source ↗
- The Osaka hardfork (KIP-279 blob transactions plus EVM/API compatibility features) activated on mainnet at block 213,333,000 (est. 7 Apr 2026); all mainnet nodes must run Kaia v2.2.2 or later. source ↗

Public Kaia RPC URLs, checked every week.
Free, shared Kaia endpoints from the chain registry that answered eth_chainId with 8217 in our weekly check (1 of 1). Good for a wallet or a test; once an app, bot or indexer depends on it, move to a dedicated Kaia RPC endpoint.

Dedicated Kaia RPC node: the questions buyers ask.
What is a Kaia RPC node?
A server running Kaia's node software (kcn, kpn, ken) that answers RPC requests: reading balances and state, and sending transactions. It can be public and free, shared by a provider's customers, or dedicated to one client.
What is a dedicated Kaia RPC node?
A Kaia node on a bare-metal server that runs for one client only, with its own private RPC endpoint. Nobody else's traffic shares the machine, so there is no rate limit and no noisy neighbour, and every method the client exposes is on. Argusnodes builds, syncs, monitors and upgrades it for you at one fixed monthly price.
Is my Kaia node managed and monitored, and what does that cost?
Yes, and so is monitoring, both at no additional cost. We set up and sync the node, watch it 24/7 with live node and server metrics in your dashboard, apply every network upgrade and client update, and fix it when something breaks. If you need help around the node, such as connecting it to your app, moving off another provider or setting up an indexer, our engineers help with that too, at the same monthly price.
What is a private Kaia RPC endpoint?
An RPC endpoint that only your applications use. It sits on a dedicated Kaia node that is yours alone, on your own domain if you want one, and answers only the IP addresses you allowlist. No other customer's traffic shares the machine, so nobody else's burst becomes your latency, and there is no rate limit to hit.
How long until my Kaia node is live?
As soon as it has synced with the Kaia network, and we tell you the moment it is ready. Sync time depends on the node type (an archive node replays the full history, so it takes longest) and the client you pick (kcn, kpn, ken), so your quote carries an estimate for your exact setup rather than a number that is sometimes wrong. The quote itself lands within the hour, around the clock.
What is included in the from $269/mo for my Kaia node?
Everything the node can do, with the premium add-ons other providers bill separately included free: unlimited RPS, every RPC method including debug and trace, unlimited WebSocket connections, your own domain with an IP allowlist, 18 cities to choose from, a 99.99% SLA with credits, 24/7 engineer support and live p50/p99 in your dashboard. There is no add-on price list because nothing is an add-on.
What hardware will my Kaia node run on?
A machine that meets Kaia's official hardware guidance (quoted in the spec sheet on this page) with headroom on top, on a dedicated bare-metal server. We never build at the minimum, because a node sized to the minimum becomes the bottleneck the day the chain grows. Ask before you order and we tell you the exact CPU, RAM and NVMe; the delivery email names the server, and root access is yours if you want it.
Which Kaia client should I choose?
kcn: kcn is the Consensus Node binary run by Governance Council validators to propose and validate blocks inside the permissioned, IP-access-controlled Core Cell network. kpn: kpn is the Proxy Node binary that fronts a CN with a public IP, relaying transactions and blocks between the CN and endpoint nodes. ken: ken is the Endpoint Node binary that provides public JSON-RPC, WebSocket and IPC access to the network and is the client to run for RPC service (full or archive).
Does Argusnodes run Kaia archive nodes and trace methods?
Yes. Kaia's documentation describes full-history operation; we run Kaia archive nodes, quoted per setup, with trace and historical queries unmetered. Debug and trace methods are on for full nodes too, within their state window.
Can I run a Kaia validator with Argusnodes?
Block production is by Consensus Nodes run by Governance Council members (minimum 5,000,000 KAIA staked, permissioned onboarding); official docs say a permissionless Phase 2 opening validator participation to anyone is scheduled for late September 2026. We run every node type the chain actually offers and none it does not.
Can I move my Kaia endpoint from another provider?
Yes. A dedicated Kaia node speaks the same JSON-RPC and WebSocket interfaces as the shared endpoint you use today, so migration is pointing your application at your own endpoint. Billing is monthly with no lock-in on our side, and support engineers are on the channels 24/7 during cutover.
Are there rate limits or connection caps on a dedicated Kaia node?
No artificial ones: unlimited RPS and no connection cap. The machine is yours alone, so the hardware is the only ceiling: if it can serve the request, you can send it. There is no per-plan connection cap because there is no plan tier.
How do I pay for my Kaia node, and can I cancel?
In crypto, with no KYC and no setup fee. Pay monthly, or save 5% quarterly and 10% annually, and your price is locked for as long as your node runs. Cancel at the end of any term; the node is provisioned for you alone, so there is no meter to escape and no exit fee.
What is the Kaia chain ID?
8217 (hex 0x2019), per Kaia's official documentation. A dedicated Kaia node answers eth_chainId with it, so wallets and libraries configured for Kaia work against your endpoint unchanged.
What is the Kaia RPC URL?
Public Kaia RPC URLs from the chain registry that answered our weekly check on chain ID 8217: https://public-en.node.kaia.io. Kaia's official documentation (docs.kaia.io) is the reference for its own endpoints. They are shared, rate limited and run by third parties, so they are fine for a wallet and not for an application. A dedicated node gives you a private Kaia RPC URL of your own, on your domain if you want, that nobody else uses.
Is Kaia RPC free?
Yes, public Kaia RPC endpoints are free: the ones that passed our weekly check are listed on this page. They are shared and rate limited, which is fine for a wallet or a test. A dedicated Kaia node is the paid option for an app, bot or indexer, at one fixed monthly price.
What is the best Kaia RPC provider?
It depends on the workload. Check four things: whether the node is single-tenant or shared, whether there are rate limits or credits, whether archive, trace and debug are included, and who answers when it breaks. For a wallet, a free public endpoint is enough. For an app, bot or indexer, a dedicated node with no rate limits avoids the throttling of shared plans. Our comparison pages (argusnodes.com/vs) set us against other providers, with sources.
How do I add Kaia to MetaMask with my own RPC URL?
Add a network manually with the chain ID 8217, the currency symbol KAIA and your private Kaia RPC URL in place of the public one. The steps are the same as for a public URL; the difference is that the endpoint is yours alone, so the wallet never hits someone else's rate limit.
