Overview

Blockchain access that keeps up when your users do.

Every wallet balance, swap quote, trading signal and dashboard starts with a call to a blockchain node. Public endpoints throttle you at peak, a single self-run node becomes a 3 a.m. pager problem, and overseas providers add distance between your Indian users and the chain.

XcellCloud Web3 Infrastructure gives you endpoints that just answer: start on an elastic RPC endpoint, move to dedicated full, archive or validator nodes when traffic or compliance demands it, and put them behind our load-balanced gateway with health checks, rate limits and alerting. Nodes sit in XcellHost's Mumbai Tier IV data centre, with partner locations on request — and the bill comes in rupees with GST.

Products
Four ways to reach the chain. Pick the one that fits today.
Start small, grow without changing code — every product speaks the same JSON-RPC and WebSocket interfaces your libraries already use.

    

      
01
Elastic RPC endpoint
A load-balanced endpoint on a shared node pool. Requests go to the healthiest node; you get an API key, a rate limit and a dashboard.
  • Fastest way to start
  • Fair-use rate limits per plan*
  • Mumbai pool, partner regions on request
from ₹2,999*/mo

      
02
Dedicated node
Single-tenant bare metal that answers only your traffic — full, archive or validator, with your choice of client and flags.
  • No request metering
  • Archive, trace & debug at no extra cost
  • Managed or unmanaged
from ₹16,999/node/mo

      
03
Flat-rate high-throughput
Two or more dedicated nodes behind our gateway, sized to a sustained requests-per-second target, so heavy days cost the same as quiet ones.
  • Sized to your RPS tier
  • Read/write split & failover
  • Archive access where you need it
nodes + ₹1,199/mo LB

      
04
Managed in your estate
Nodes on your own servers or in a cage in our data centre, run by our NOC from one runbook — patching, re-syncs, monitoring and self-healing restarts.
  • Your hardware, our operations
  • Co-location in Mumbai
  • Same dashboards and alerts

Ethereum, major L2s, Solana, Polygon, BNB Chain and more*
The networks we run most often today, taken from our Dedicated RPC Node line-up. Not listed? Tell us the client and we will check it.

    

      
    

    

    
* Availability, node builds and validator support vary by network and are confirmed on quotation. Chain and client names are trademarks of their owners, used only to describe compatibility; XcellHost provides infrastructure and is not affiliated with these networks.

  





  

    
Data & APIs
More than "latest block". The whole history, streamed.
Standard interfaces only — nothing proprietary to learn and nothing that locks you in.

    

      

        
HTTPS JSON-RPCReads, calls and transaction broadcast with the methods your SDK already uses.

        
WebSocket subscriptionsNew heads, logs and pending transactions pushed to you as they happen.

        
Trace & debug APIsCall traces and transaction replays for explorers, debuggers and compliance tools.

        
Archive dataFull historical state from genesis on archive builds — balances and storage at any past block.

        
Indexing & subgraphsHosted open-source indexers and subgraph-style pipelines that turn events into queryable tables*.

        
Data exportsBlock, log and transfer exports to your warehouse for analytics, risk and reporting*.

* Indexing and data-export pipelines are scoped per project. Trace and debug methods depend on the client (for example Erigon or Reth on Ethereum) and the node build.

  





  

    
Reliability & security
Built so one bad node never becomes your outage.

    

      
Load balancing & failover
The gateway health-checks every node on block height and response time and drops a lagging node out of rotation automatically. Reads and writes can be split.

      
Monitoring & alerting
Block lag, peer count, disk, error rates and latency watched by our 24×7 NOC, with alerts to you by email, Teams or WhatsApp.

      
Rate limits you control
Per-key requests-per-second limits and method allow-lists, so one runaway script cannot starve your production app.

      
API key security
Keys rotated on schedule, scoped per app, with IP and origin restrictions. For signing keys and secrets, custody in our Cloud HSM.

      
DDoS & edge protection
Public endpoints sit behind network DDoS filtering, with WAAP available for dApp front ends and APIs.

      
Private by default
Dedicated nodes are allow-listed to your IPs; add Private Connect for a private link with no public listener at all.

    

  





  

    
Global vs India-hosted
Close to India in Mumbai. Further afield on request.
Mumbai is XcellHost's own Tier IV facility. Other locations come through partner data centres on request — chosen to sit near your users or the network you follow.

Why teams build on XcellCloud
Four reasons, no logo wall.

    

      
Many chains, one contract
EVM networks, rollups, Solana-class and UTXO chains from one supplier, one dashboard and one INR invoice — mainnet and testnet.

      
Security first
Single-tenant bare metal for dedicated nodes, encrypted endpoints, allow-lists and key custody, inside ISO 27001-certified operations.

      
History on tap
Archive nodes and exports for indexing, analytics, risk models and AI training data — no per-call surcharge on dedicated builds.

      
Ready for AI agents
Standard JSON-RPC and WebSocket endpoints any agent framework can call to read state or submit signed transactions, with keys scoped per agent.

    

  





  

    
How it works
One request, five hops, a few milliseconds.
What happens between your app calling the endpoint and the answer coming back.

01Authenticate
The gateway checks your API key, origin and IP, then applies your per-key rate limit and method rules.

      
02Route
The balancer sends the call to the healthiest in-sync node — heavy archive or trace calls to archive builds.

      
03Answer
The node executes the call and the result streams back over HTTPS or the open WebSocket.

      
04Watch
Latency, errors and block lag are recorded; a lagging node leaves rotation and our NOC is paged.

PMLAFIU-IND registration
A Finance Ministry notification of 7 March 2023 made VDA service providers — exchange, transfer, safekeeping and issuer-related services — reporting entities under the PMLA. They register with FIU-IND, run KYC, report suspicious transactions and keep records for five years. Our logs and India-hosted storage support that record-keeping.

      
6 h · 180 dCERT-In directions
CERT-In's directions of 28 April 2022 require cyber incidents to be reported within 6 hours and ICT logs to be kept for 180 days within India, and VDA exchange and custodian wallet providers to keep KYC and transaction records for five years. Gateway and node logs can be retained in Mumbai to match.

      
DPDPDPDP Act 2023 & Rules 2025
Wallet-linked and KYC data is personal data. The Act requires reasonable security safeguards and breach intimation to the Data Protection Board and affected people; the Rules were notified in November 2025 and phase in. India-hosted nodes and logs keep that data in the country.

    

    
Summaries reused from our Applied Blockchain Security page (checked October 2026 against Finance Ministry / FIU-IND, CERT-In and MeitY publications), for orientation only — not legal, tax or financial advice. XcellHost provides infrastructure; registration and reporting remain your responsibility.
