Kusama is the canary network for Polkadot, with faster, lower-bar governance for bold releases; application logic lives on parachains. Keep your endpoint private behind IP allowlisting and a reverse proxy, and keep admin RPC closed.

// use cases

What Teams Build On Kusama Nodes

Where a private, uncapped endpoint beats a shared RPC pool.

Pre-Production Testing Environment

Stage Polkadot projects on Kusama before mainnet. Dedicated CPU, RAM, and NVMe I/O keep behavior predictable across faster governance and upgrade cycles, giving teams a production-like canary network without shared-endpoint throttling.

Validator Node Operations

Run high-performance validator nodes on hardware tuned for Kusama's NPoS consensus. Dedicated resources keep block production and finality participation steady, protecting your stake and rewards from missed slots caused by noisy-neighbor contention.

Parachain Development & Deployment

Develop and test parachains with dedicated resources sized for collator and relay chain workloads. Isolated hardware absorbs Kusama's faster governance and upgrade cadence, so teams iterating on runtime logic ship sooner before a Polkadot launch.

DeFi Protocol Experimentation

Support experimental DeFi apps that handle Kusama's rapid transaction volume and parameter changes. Unlimited RPC calls and zero throttling keep quoting and execution responsive during volatility, for protocols proving out mechanics before Polkadot deployment.

NFT Platform Development

Power NFT projects with high-throughput infrastructure built for complex minting and marketplace transactions. Dedicated capacity keeps contract reads steady during mint storms and reveal pipelines, for creators and marketplaces that break on shared RPC during spikes.

Staking Service Operations

Provide reliable nominator and validator services on Kusama's NPoS system with high-uptime nodes. Consistent participation maximizes staking rewards and protects against slashing from downtime, for staking providers who depend on stable, predictable infrastructure.

// how it works

From Kusama To Private Endpoint In 3 Steps

Pick a node, we provision dedicated bare metal, you get a private, snapshot-ready RPC URL.

  1. 01

    Pick Your Kusama Node

    Choose full, archive, or validator. We run the polkadot binary with --chain kusama on ParityDB; tell us your target region and whether you need relay chain, parachains, or both.

  2. 02

    We Provision Bare Metal

    Your single-tenant node deploys on NVMe tuned for single-thread speed, snapshot synced so you skip the long cold sync from genesis.

  3. 03

    Get Your Private Endpoint

    Receive a dedicated JSON-RPC endpoint over HTTP and WSS with unlimited requests and zero rate limits, private behind IP allowlisting and DDoS protection.

// latency & locations

Put Your Node Where Milliseconds Are Won

RPC latency is mostly a function of distance. A dedicated node lets you choose the exact region, so you sit next to the traffic that matters instead of fighting for routing on a shared, far-away endpoint.

Place It Where Your Users Are

Deploy across 20+ Tier III locations in the US, EU, Asia, and Australia. Put your Kusama node in the region your traffic actually comes from, not wherever a shared pool happens to route you.

Cut The Round Trips

RPC latency is mostly physical distance. Running in the same region as your users and the Kusama network's peers shaves the round-trips a far-away, shared endpoint can never give back, which is what high-frequency reads and transaction submission live or die on.

Multi-Region By Design

Run a primary node plus regional read replicas for fast reads everywhere and built-in redundancy. Split public read endpoints from private admin, debug, and trace endpoints.

Need a node within a target latency budget of a specific region or venue? Tell us the endpoint and we'll recommend the closest facility.

// supported chains

One Backbone For Every Major Chain

Run validators, RPC, and archive nodes across the chains your stack depends on, all on the same dedicated bare metal, with the same isolation, speed, and control.

Frequently Asked Questions

Chain IDs, clients, archive data, getLogs limits, and why dedicated beats compute-unit billing.

What exactly is a Dedicated Kusama RPC Node server?

A dedicated Kusama RPC node server provides exclusive server resources specifically optimized for Kusama's experimental blockchain environment. Unlike shared solutions, you get isolated hardware with dedicated computing resources, custom-tuned for the unique demands of Kusama's canary network for Polkadot. On RedSwitches you run this on bare metal with root access, so you control the client, configs, and capacity.

Why should I use a dedicated server for running a Kusama node?

A dedicated server gives your node exclusive access to computing resources, so it processes and validates transactions with minimal latency. You get an isolated infrastructure that allows custom firewalls and stringent access controls, which reduces vulnerabilities compared to multi-tenant hosting. Uptime and synchronization stay consistent because dedicated resources are never contended by other users. For RPC-heavy applications you get unrestricted access with no throttling, which is essential for explorers, wallets, and other demanding dApps.

What are the hardware requirements for setting up a dedicated Kusama node server?

For high-performance Kusama nodes serving RPC operations, we suggest a multi-core processor (8 cores or more), 64 GB of RAM, 2 x 3.84 TB NVMe enterprise drives, and a high-speed connection with a minimum 10 Gbps upload speed. Storage is the part that grows, so leave NVMe headroom, and archive builds need significantly more disk than pruned full nodes.

How do I set up a Kusama node?

Since Kusama is the canary network for Polkadot, you install the Polkadot binaries and run the node with the kusama chain spec. Pull the latest release from the Polkadot SDK GitHub repository (we recommend cURL), give the directory execute permission, then run the binary with --chain kusama appended so the process follows Kusama node setup. We recommend Ubuntu 22.04 LTS or the latest stable Linux distribution. Always run the most recent binaries to get the latest bugfixes, and review your firewall and server security regularly.

Should I run a validator node or an RPC node on Kusama?

For high-performance validator participation we suggest 16 cores or more (AMD EPYC preferred), 256 GB ECC DDR4, a minimum 2 TB NVMe SSD for ledger data, and a stable link from 1 Gbps to 100 Gbps. An RPC node is sized lighter and exists to serve your apps' JSON-RPC reads and transaction flow. Many teams keep them separate so validator duties are never disturbed by RPC query load. Either way you can run it yourself with full root access or choose our fully managed option.

What are the available Kusama JSON-RPC API methods?

A Kusama node exposes the Substrate JSON-RPC surface for programmatic interaction. This includes authoring and extrinsics calls (author_submitExtrinsic, author_submitAndWatchExtrinsic), chain and block lookups (chain_getBlock, chain_getHeader, chain_subscribeNewHead), state queries (state_getStorage, state_getMetadata, state_getRuntimeVersion, state_queryStorageAt), child storage, BEEFY and GRANDPA finality, and system information (system_health, system_syncState, system_version). On a dedicated node you control which methods you expose. Refer to the official Kusama documentation for the full list.

Do I need an archive node or a pruned full node for my use case?

Most production apps work on a pruned full node. It serves current-state reads and transaction flow while keeping storage manageable. Choose an archive node, run with --state-pruning archive, when you need historical state at older blocks for indexers, explorers, analytics, or audits. Archive costs more because relay chain and parachain history grow continuously, so plan extra NVMe and RAM headroom.

Why use RedSwitches for Kusama API access?

RedSwitches offers dedicated Kusama RPC node servers with no rate limits, sub-50ms response times, and 24/7 availability. You deploy across 20+ worldwide data centers to cut latency and speed up parachain synchronization, with included DDoS protection and software-defined firewalls. Snapshot-synced nodes are delivered fast, and a managed option covers pre-configured hardware, geo-optimized deployment, SLA-backed uptime, and Kusama-specialized engineers.

Do you charge per request or per compute unit?

No. Unlike shared RPC providers that bill per "compute unit" and throttle you past a quota, a dedicated node is a flat monthly price with unlimited requests and zero overages. One node equals all the throughput your hardware can serve. That makes budgeting predictable and removes the surprise bills that come with usage-based RPC pricing.

How is this different from a shared RPC endpoint?

Shared RPC pools serve thousands of customers from pooled infrastructure, so you inherit rate limits, noisy-neighbor latency, and compute-unit billing. A RedSwitches node runs on single-tenant bare metal that is yours alone: reserved CPU, RAM, and NVMe, a dedicated 10/25 Gbps port, and a private endpoint you control. Performance tracks your hardware, not another tenant's traffic.

Do I have to sync the node myself, or wait days for it?

No. We provision from current snapshots so your node is live in hours rather than syncing from genesis for days. You can run it yourself with full root access, or choose our fully managed option where our engineers handle the sync, updates, and monitoring. Either way you receive a working private endpoint, not an empty server.

Can I deploy close to a specific region or sequencer?

Yes. With 20+ Tier III locations across the US, EU, Asia, and Australia you can place your node in the same region as your users or a chain's sequencer to cut round-trip latency. Tell us your target region and we will recommend the closest facility. You can also run multi-region nodes for redundancy and split read and write endpoints.
