Dedicated Ink RPC node. A private Ink RPC endpoint that only you use: no rate limits, every method on, one fixed monthly price.
Ink is an Ethereum layer-2 built by Kraken on the OP Stack, part of the Optimism Superchain.

| Node software | op-geth, op-node |
| Interfaces | JSON-RPC, WebSocket |
| Full node | Yes, from $399/mo |
| Archive node | Yes, from $399/mo |
| Validator | OP-stack L2 operated with a sequencer; official docs cover RPC full and archive nodes only. |

| Official hardware guidance | Recommended hardware for an Ink mainnet node (op-geth/op-node Compose stack, full or archive): 16GB+ RAM, 2 TB SSD (NVME recommended), 100 Mbps+ download; testnet: 16GB+ RAM, 500 GB SSD. 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 Ink recently
- op-geth support ended May 31, 2026; Optimism says all node operators should migrate to op-reth (v2.2.3 or later), and op-geth cannot follow the now-active Karst hard fork. source ↗
- Upgrade 19 (Karst hard fork) activated on mainnet OP Stack chains including Ink on July 8, 2026 16:00:01 UTC, requiring op-node v1.19.1 and op-reth v2.3.3 before activation. source ↗
- Ink announced (June 23, 2026) that it is moving to OP Enterprise Fully Managed, with Optimism running sequencers, RPC, explorer and incident response from an August 2026 cutover; chain ID and contracts are unchanged, and features like one-day withdrawals and 200ms subblocks are planned. source ↗
- The inkonchain/node repo (last commit August 5, 2026) still ships only op-geth and an archive path that depends on geth snapshots from the Gelato index; its README says an op-reth Compose path is still pending. source ↗

Public Ink RPC URLs, checked every week.
Free, shared Ink endpoints from the chain registry that answered eth_chainId with 57073 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 Ink RPC endpoint.

Dedicated Ink RPC node: the questions buyers ask.
What is a Ink RPC node?
A server running Ink's node software (op-geth, op-node) 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 Ink RPC node?
A Ink 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 Ink 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 Ink RPC endpoint?
An RPC endpoint that only your applications use. It sits on a dedicated Ink 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 Ink node is live?
As soon as it has synced with the Ink 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-geth, op-node), 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 $399/mo for my Ink 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 Ink node run on?
A machine that meets Ink'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 Ink client should I choose?
op-geth: documented by Ink op-node: The OP Stack rollup/consensus client that derives L2 blocks from L1 and drives the execution client; not deprecated and required for every Ink node.
Does Argusnodes run Ink archive nodes and trace methods?
Yes. Ink's documentation describes full-history operation; we run Ink archive nodes, from $399/mo, with trace and historical queries unmetered. Debug and trace methods are on for full nodes too, within their state window.
Can I run a Ink validator with Argusnodes?
OP-stack L2 operated with a sequencer; official docs cover RPC full and archive nodes only. We run every node type the chain actually offers and none it does not.
Can I move my Ink endpoint from another provider?
Yes. A dedicated Ink 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 Ink 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 Ink 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 Ink chain ID?
57073 (hex 0xdef1), per Ink's official documentation. A dedicated Ink node answers eth_chainId with it, so wallets and libraries configured for Ink work against your endpoint unchanged.
What is the Ink RPC URL?
Public Ink RPC URLs from the chain registry that answered our weekly check on chain ID 57073: https://rpc-gel.inkonchain.com, https://rpc-qnd.inkonchain.com. Ink's official documentation (docs.inkonchain.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 Ink RPC URL of your own, on your domain if you want, that nobody else uses.
Is Ink RPC free?
Yes, public Ink 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 Ink node is the paid option for an app, bot or indexer, at one fixed monthly price.
What is the best Ink 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 Ink to MetaMask with my own RPC URL?
Add a network manually with the chain ID 57073, the currency symbol ETH and your private Ink 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.
