What changed on X Layer recently
- On 27 October 2025 (11:30 PM UTC+8, about one hour of paused block production) X Layer's mainnet was migrated from the Polygon zkEVM/CDK validity rollup to an OP Stack optimistic rollup; OKX confirmed completion on 28 October 2025, and Optimism announced the migration on 9 December 2025. source ↗
- Post-migration the official node stack is op-node plus the reth execution client (okx/xlayer-reth); xlayer-reth provides legacy RPC routing (--rpc.legacy-url) for history from before the migration, so operators serving full history need a legacy endpoint or archive snapshot. source ↗
- Before the OP Stack move, X Layer completed the Polygon CDK 'PP upgrade' on 5 August 2025 (announced 13 August 2025 with an OKB burn); that CDK-era node software is superseded. source ↗
- X Layer now ships Flashblocks (3 to 5 sub-blocks per 1-second L2 block) streamed over the default WebSocket subscription from reth sequencers; RPC nodes wanting Flashblocks need the Flashblocks-enabled reth option in the one-click setup. source ↗

Public X Layer RPC URLs, checked every week.
Free, shared X Layer endpoints from the chain registry that answered eth_chainId with 196 in our weekly check (2 of 2). Good for a wallet or a test; once an app, bot or indexer depends on it, move to a dedicated X Layer RPC endpoint.

Dedicated X Layer RPC node: the questions buyers ask.
What is a X Layer RPC node?
A server running X Layer's node software (op-node, xlayer-reth) 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 X Layer RPC node?
A X Layer 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 X Layer 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 X Layer RPC endpoint?
An RPC endpoint that only your applications use. It sits on a dedicated X Layer 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 X Layer node is live?
As soon as it has synced with the X Layer 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 (op-node, xlayer-reth), 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 X Layer 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 X Layer node run on?
A machine that meets X Layer'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 X Layer client should I choose?
op-node: op-node is the OP Stack consensus/rollup node that derives the L2 chain from Ethereum L1 and drives the execution client over the Engine API; it is required alongside any execution client. xlayer-reth: xlayer-reth is OKX's customised Reth execution client and the default in the official one-click RPC setup; it adds legacy RPC routing (--rpc.legacy-url) so historical pre-migration data can still be served.
Does Argusnodes run X Layer archive nodes and trace methods?
Yes. X Layer's documentation describes full-history operation; we run X Layer 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 X Layer validator with Argusnodes?
Block production is via a sequencer; permissionless block production is not offered. We run every node type the chain actually offers and none it does not.
Can I move my X Layer endpoint from another provider?
Yes. A dedicated X Layer 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 X Layer 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 X Layer 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 X Layer chain ID?
196 (hex 0xc4), per X Layer's official documentation. A dedicated X Layer node answers eth_chainId with it, so wallets and libraries configured for X Layer work against your endpoint unchanged.
What is the X Layer RPC URL?
Public X Layer RPC URLs from the chain registry that answered our weekly check on chain ID 196: https://rpc.xlayer.tech, https://xlayerrpc.okx.com. X Layer's official documentation (web3.okx.com) 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 X Layer RPC URL of your own, on your domain if you want, that nobody else uses.
Is X Layer RPC free?
Yes, public X Layer 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 X Layer node is the paid option for an app, bot or indexer, at one fixed monthly price.
What is the best X Layer 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 X Layer to MetaMask with my own RPC URL?
Add a network manually with the chain ID 196, the currency symbol OKB and your private X Layer 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.
