Dedicated Kasplex RPC node. A private Kasplex RPC endpoint that only you use: no rate limits, every method on, one fixed monthly price.
Kasplex is an EVM-compatible based rollup on Kaspa whose transactions are ordered by Kaspa L1 miners (GHOSTDAG) and paid in bridged KAS; full ZK-proof settlement is scheduled on the 2026 roadmap.

Kasplex node requirements, and what we build.
Chain facts from Kasplex's official documentation (docs-kasplex.gitbook.io). Where it is silent, the row says so.
| Node software | Kasplex zkEVM Node (geth + syncer) |
| Interfaces | JSON-RPC, WebSocket |
| Full node | Yes, from $99/mo |
| Archive node | Yes, quoted per setup |
| Validator | A based rollup with no centralized sequencer; docs describe RPC node modes, not validators. |
| Chain ID | 202555 |
| Gas token | KAS |
| Official hardware guidance | Official Docker node (syncer mode, geth + syncer): 'At least 4GB available memory' and 'At least 100GB available disk space', plus Docker and Docker Compose; no CPU figure and the GitBook docs give no hardware numbers. source ↗ |
| Argusnodes build | Meets the official guidance above with headroom on top, never at the minimum. Ask and we tell you the exact CPU, RAM and NVMe; root access on request. |
What changed on Kasplex recently
- Kasplex Network Mainnet (RPC evmrpc.kasplex.org, chain ID 202555) is live per the official network information, and the mainnet node configuration was added to the official Docker node repo on 24 October 2025 (checkpoint source switched 8 April 2026). source ↗
- The 2026 roadmap schedules an SGX prover on mainnet in April 2026, RETH client support in Q2, the Glamsterdam EVM upgrade in August and full ZK covenant rollup settlement on Kaspa L1 by September 2026. source ↗
- The docs' risk disclosure warns that some described technical specifications may apply to future versions of Kasplex L2 rather than the current network. source ↗

Dedicated Kasplex RPC node: the questions buyers ask.
What is a Kasplex RPC node?
A server running Kasplex's node software (Kasplex zkEVM Node (geth + syncer)) 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 Kasplex RPC node?
A Kasplex 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 Kasplex 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 Kasplex RPC endpoint?
An RPC endpoint that only your applications use. It sits on a dedicated Kasplex 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 Kasplex node is live?
As soon as it has synced with the Kasplex 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), 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 $99/mo for my Kasplex 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 Kasplex node run on?
A machine that meets Kasplex'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.
Does Argusnodes run Kasplex archive nodes and trace methods?
Yes. Kasplex's documentation describes full-history operation; we run Kasplex 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 Kasplex validator with Argusnodes?
A based rollup with no centralized sequencer; docs describe RPC node modes, not validators. We run every node type the chain actually offers and none it does not.
Can I move my Kasplex endpoint from another provider?
Yes. A dedicated Kasplex 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 Kasplex 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 Kasplex 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 Kasplex chain ID?
202555 (hex 0x3173b), per Kasplex's official documentation. A dedicated Kasplex node answers eth_chainId with it, so wallets and libraries configured for Kasplex work against your endpoint unchanged.
What is the Kasplex RPC URL?
The public Kasplex RPC URLs are listed in Kasplex's official documentation (docs-kasplex.gitbook.io). 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 Kasplex RPC URL of your own, on your domain if you want, that nobody else uses.
Is Kasplex RPC free?
Public Kasplex endpoints are free and listed in Kasplex's official documentation (docs-kasplex.gitbook.io). They are shared and rate limited, which is fine for a wallet or a test. A dedicated Kasplex node is the paid option for an app, bot or indexer, at one fixed monthly price.
What is the best Kasplex 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 Kasplex to MetaMask with my own RPC URL?
Add a network manually with the chain ID 202555, the currency symbol KAS and your private Kasplex 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.
