Firo RPC · Ready to deploy

Dedicated Firo RPC node. A private Firo RPC endpoint that only you use: no rate limits, every method on, one fixed monthly price.

Firo (formerly Zcoin) is a privacy-focused cryptocurrency using the Spark protocol for private transactions without a trusted setup. It combines FiroPoW proof-of-work mining with a masternode layer that provides LLMQ ChainLocks and InstantSend.

What changed on Firo recently

  • On August 13, 2026 Firo disclosed and mitigated a Spark protocol vulnerability (coin forgery in multi-input spends; about 200 FIRO minted by the researcher on mainnet) and shipped mandatory v0.14.17.2, which restricts each Spark spend to a single coin until the v0.14.18.0 hard fork targeted for the third week of August 2026. source ↗
  • v0.14.16.0 (May 15, 2026) and v0.14.16.1 (June 3, 2026) were mandatory upgrades with a deadline at block 1,329,000 (about June 22, 2026), adding Spark Name renewal, extension and transfer fixes. source ↗
  • v0.14.15.0 (October 20, 2025) was a mandatory upgrade with a deadline at block 1,205,100 (about November 19, 2025), adding Spark Name transfers and Sigma stripping; further point releases v0.14.15.1 to v0.14.15.3 followed through March 10, 2026. source ↗
  • The client is actively maintained (repository pushed August 22, 2026). source ↗

Before you order

Dedicated Firo RPC node: the questions buyers ask.

What is a Firo RPC node?

A server running Firo's node software (firod) 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 Firo RPC node?

A Firo 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 Firo 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 Firo RPC endpoint?

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

As soon as it has synced with the Firo 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 Firo node?

Everything the node can do, with the premium add-ons other providers bill separately included free: unlimited RPS, every RPC method including heavy queries, unlimited 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 Firo node run on?

A machine that meets Firo'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 Firo archive nodes?

Yes. Firo's documentation describes full-history operation; we run Firo archive nodes, from $99/mo, with historical queries unmetered.

Can I run a Firo validator with Argusnodes?

Blocks are mined by proof of work; the stakeable role is the masternode (1,000 FIRO collateral), which secures ChainLocks and InstantSend rather than producing blocks We run every node type the chain actually offers and none it does not.

Can I move my Firo endpoint from another provider?

Yes. A dedicated Firo node speaks the same JSON-RPC and ZMQ 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 Firo 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 Firo 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 Firo RPC URL?

The public Firo RPC URLs are listed in Firo's official documentation (firo.org). 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 Firo RPC URL of your own, on your domain if you want, that nobody else uses.

Is Firo RPC free?

Public Firo endpoints are free and listed in Firo's official documentation (firo.org). They are shared and rate limited, which is fine for a wallet or a test. A dedicated Firo node is the paid option for an app, bot or indexer, at one fixed monthly price.

What is the best Firo 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.
