Shared Karura RPC pools throttle you, bill you per compute unit, and seat you next to noisy neighbors. A dedicated Karura node is your own private backbone: flat-priced, uncapped, and yours alone.
The networks, node software, interfaces, and chain parameters your dedicated Karura node ships with. Karura is Acala’s canary parachain on Kusama and exposes BOTH the Substrate JSON-RPC and, through the Acala EVM+ eth-rpc adapter, an Ethereum-compatible JSON-RPC, so Polkadot.js and EVM tooling both connect.
You control which namespaces are exposed. Enable debug and trace on archive builds, keep the rest private behind IP allowlisting.
Where a private, uncapped endpoint beats a shared RPC pool.
Karura is the DeFi hub of Kusama, with staking, swaps, borrowing, and a stablecoin. Your endpoint serves state reads and submission so launches and campaign spikes avoid shared-pool throttling.
Acala EVM+ runs Solidity contracts with native Substrate features. A dedicated node serves contract reads, gas estimation, and broadcast over standard Web3 tooling, fit for production traffic.
Wallets need fast reads and steady submission. Your Karura endpoint serves balances, nonce checks, and broadcast over both interfaces, so a dedicated setup avoids congestion-driven timeouts during spikes.
Explorers and indexers run heavy historical queries nonstop. A dedicated archive node supports long-running ingestion and deep lookups across Substrate and EVM+ data without shared-endpoint limits.
Many Karura apps rely on WSS feeds for live events and UI updates. A dedicated endpoint keeps long-lived connections stable during busy periods, fit for dashboards and real-time notifications.
Teams want Karura access without exposing endpoints publicly. Restrict access by IP and network rules for internal apps and partner systems, with a clearer security posture.
Pick a node, we provision dedicated bare metal, you get a private, snapshot-ready RPC URL.
Choose a full or archive node. We run the Acala client with its Kusama relay chain node; tell us if you need Substrate JSON-RPC, Acala EVM+, or both, and your region.
Your single-tenant node deploys on NVMe tuned for single-thread speed, snapshot-restored for both the parachain and relay chain, so you skip the long cold sync.
Receive a dedicated Substrate and Acala EVM+ JSON-RPC endpoint over HTTP and WSS with unlimited requests and zero rate limits, private behind IP allowlisting and DDoS protection.
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.
Deploy across 20+ Tier III locations in the US, EU, Asia, and Australia. Put your Karura node in the region your traffic actually comes from, not wherever a shared pool happens to route you.
RPC latency is mostly physical distance. Running in the same region as your users and the Karura 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.
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.
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.
Real reviews from Trustpilot, HostAdvice, Cryptwerk, and Google.
Port speeds on cloud were capped and shady. With RS I actually get the 25Gbps they say. No throttle bs.
Network has been rock solid. They’ve got Tier 1 carriers like Arelion, GTT, and TATA… We just ping them on Telegram and they sort things out quickly.
Set up multiple Solana + Avalanche validators through them. Hardware was clean, latency was low (especially in Europe), and uptime’s been 100% so far.
As a sysadmin, I care more about control than flashy dashboards. RedSwitches gives me root access, IPMI, and actual hardware specs I can configure. Good for serious users.
We were searching for a truly reliable and stable hosting provider with maximum uptime and a powerful network infrastructure to ensure the lowest possible latency. RedSwitches not only met but exceeded our expectations.
RedSwitches gave us full control over our infrastructure without the vendor lock-in we kept running into with cloud hosts. Customizable builds, fast provisioning, and actual humans handling support tickets. It’s refreshing.
My website works smoothly, thanks to their 99.99% uptime guarantee. The support team is another plus for me, as I always have been able to get help whenever I needed it in just 5 minutes on average.
Deployed a few Ethereum and Bitcoin nodes here. Uptime’s been flawless, and sync speed was great thanks to their storage config.
They provide what they promise, I got no throttling while running my RPC Nodes. I got server in a Amsterdam for the best price.
I am using their 10gbps streaming server for last 6 months and I have no complaints. Extremely quick live chat support and I love that they accept crypto.
A really great hosting provider - what stands out the most is the stability of the network connection and the wide selection of bare metal servers. We’re very satisfied, and RedSwitches covers all of our needs.
Pros: Extremely reliable hardware, low-latency network, transparent billing… Great choice if you need raw power without cloud complexity. Works well for our dev environment and some AI workloads.
I have worked with OVH and Contabo in the past, but RedSwitches hit a better balance of price vs. support. Not the cheapest, but I get better performance and faster help.
Been using RedSwitches for 6 months now for my small game server biz. Uptime has been great, and I haven’t run into any hidden charges.
Using the storage servers to archive logs and snapshots from our AI pipeline… I also love that I could pick the datacenter closest to our team.
Support is super responsive. I had an issue with an OS reinstall and they jumped in within 10 minutes… Transparent pricing = win.
They have an instant delivery section… they delivered it within 120 mins with all my requirements fulfilled (OS/RAID/Software configured etc).
A dedicated server has been installed within 30 minutes. Thirty minutes. It takes DAYS for some famous providers out there, but these guys do their work right.
I have been using their services for over 5+ years… Uptime: 10/10, Network: 10/10, Hardware Quality: 10/10, Customer Support: 20/10 (No, That’s Not A Typo).
They offer top quality hardware, excellent uptime and very responsive support… They helped us scale our business exponentially and we went from 1 server to 14 dedicated servers in less than a year.
Great hardware, non congested network and excellent service. Already using them for over a year and would definitely recommend Redswitches if you are looking for a reliable hosting provider.
With servers available in numerous strategic locations, RedSwitches offers exceptional versatility and performance for our company’s diverse hosting needs. Plus, their no setup fee policy really helps keep costs down.
"Your server is ready" - I read this message within 30 mins of starting the chat with their Sales Team… Excellent DELL Hardware and 100% Uptime.
The dedicated server I got from RedSwitches has been incredibly reliable and fast. Their bare metal cloud solutions offer excellent performance, and the cloud VPS options are perfect for scaling. Highly recommended!
I have been using their dedicated server from 9 months now. Starting from pre-sales till today I have not experienced downtime or lack of support.
First of all, all services work as expected - secondly - support is outstanding, no matter when you start the conversation with colleagues at support they have knowledge to help you out.
We have been using Red Switches for several years since 2021. I have never experienced such fast customer service.
Absolutely delighted with RedSwitches! The setup was quick and free, and the fact that they accept all major payment gateways made the process seamless.
Very good experience using their bare metal servers. Their customer service is one of the finest I have experienced - always prompt at resolving troubles. Highly recommend.
Chain IDs, clients, archive data, getLogs limits, and why dedicated beats compute-unit billing.
Karura is the decentralized finance hub of Kusama, offering staking, swapping, borrowing, and a stablecoin. It is the canary network of Acala, running nearly the same codebase as a Kusama parachain so new features are battle-tested in a live environment. Its native token is KAR, which is also used as gas on Acala EVM+.
Yes. Karura runs the Substrate JSON-RPC (chain, state, system, author) over HTTP and WSS for Polkadot.js, plus Acala EVM+, which serves an Ethereum-compatible JSON-RPC through the eth-rpc adapter with EVM chain ID 686 for Web3.js and Ethers.js. You can use either interface on the same dedicated host.
No. Karura is a Kusama parachain, not a standalone Layer 1. Block production is handled by collators, while finality is provided by the Kusama relay chain. In practice a full Karura node runs the Acala client alongside an embedded relay chain node, which we account for in sizing and sync.
Most teams start with a full Karura node because it serves current-state reads and transaction submission with far lower storage needs. Choose archive RPC when your product must query full history, power explorers, run deep analytics, or support heavy historical lookups. If you are unsure, tell us your workload and we will map you to the right node type.
A shared Karura RPC provider runs many customers on pooled infrastructure, which can create unpredictable latency during spikes plus shared rate limits and noisy-neighbor slowdowns. Dedicated Karura RPC node servers give you single-tenant resources, your own access rules, and clearer fault boundaries. You control performance and security instead of inheriting someone else's traffic.
Provisioning is fast. The real variable is sync time, which depends on chain state, node type, storage speed, and network conditions. A full RPC usually reaches a usable state earlier than an archive setup because an archive has far more data to process. We deploy according to sync time, restoring from snapshots where available, so you are not sold a fake instant promise.
Yes. Most developers use Polkadot.js over WebSocket for subscriptions and real-time updates. Your dedicated Karura node can expose WSS endpoints for app usage, and you can keep them private or public based on your access model. For tighter control, you can restrict access by IP and allow only trusted clients.
Yes. That is a core benefit of running a dedicated Karura RPC node on dedicated servers. You can scale up resources as load grows, add storage for archive needs, and move to higher core counts for heavy concurrency. This keeps your endpoint stable while your product grows, without rebuilding everything on a new platform.
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.
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.
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.
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.

From $199/mo flat, sized to your chain's node specs and typically 30-40% below other providers. Snapshot-ready provisioning, zero setup fees, 24/7 Web3 engineers, no compute units, no rate limits.
