What changed on Unichain recently

  • Official node repo moved to op-reth (op-reth v2.3.3 + op-node v1.19.2 as of Aug 2026); docs page still shows op-geth flags. Unichain publishes no hardware requirements and defers to Optimism docs.
  • Serving Flashblocks (200 ms preconfirmations) requires an op-reth-based client subscribed to the Unichain Flashblocks WebSocket stream. source ↗

Public Unichain RPC · checked 26 Oct 2026

Public Unichain RPC URLs, checked every week.

Free, shared Unichain endpoints from the chain registry that answered eth_chainId with 130 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 Unichain RPC endpoint.

Before you order

Dedicated Unichain RPC node: the questions buyers ask.

What is a Unichain RPC node?

A server running Unichain's node software (op-node, op-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 Unichain RPC node?

A Unichain 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 Unichain 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 Unichain RPC endpoint?

An RPC endpoint that only your applications use. It sits on a dedicated Unichain 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 Unichain node is live?

As soon as it has synced with the Unichain network, and we tell you the moment it is ready. Sync time depends on the node type and the client you pick (op-node, op-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 $139/mo for my Unichain 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 Unichain node run on?

A machine that meets Unichain's official requirements 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 Unichain client should I choose?

op-node: OP Stack rollup/consensus client, run with --network=unichain-mainnet alongside the execution client. op-reth: Execution client used by the official unichain-node compose (op-reth v2.3.3, execution-layer sync driven by op-node); also the base for serving Flashblocks via base-node-reth with --websocket-url=wss://mainnet-flashblocks.unichain.org/ws.

Does Argusnodes run Unichain archive nodes and trace methods?

Archive support on Unichain is confirmed against its documentation as part of your quote. Every method the client exposes is on by default at no extra charge.

Can I run a Unichain validator with Argusnodes?

OP-stack rollup with sequencer-based block production; no validator role documented. We run every node type the chain actually offers and none it does not.

Can I move my Unichain endpoint from another provider?

Yes. A dedicated Unichain 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 Unichain 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 Unichain 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 Unichain chain ID?

130 (hex 0x82), per Unichain's official documentation. A dedicated Unichain node answers eth_chainId with it, so wallets and libraries configured for Unichain work against your endpoint unchanged.

What is the Unichain RPC URL?

Public Unichain RPC URLs from the chain registry that answered our weekly check on chain ID 130: https://mainnet.unichain.org, https://unichain-rpc.publicnode.com. Unichain's official documentation (developers.uniswap.org) 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 Unichain RPC URL of your own, on your domain if you want, that nobody else uses.

Is Unichain RPC free?

Yes, public Unichain 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 Unichain node is the paid option for an app, bot or indexer, at one fixed monthly price.

What is the best Unichain 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 Unichain to MetaMask with my own RPC URL?

Add a network manually with the chain ID 130, the currency symbol ETH and your private Unichain 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.
