Kaspa Nodes

This guide walks you through the process of deploying, managing, and connecting to a Kaspa Node (Mainnet or Testnet) using FluxCloud. Whether you’re setting up a new node or maintaining an existing one, this page provides step-by-step instructions and key details for a seamless experience.

How To Install a Kaspa Node​

Overview​

Deploying a Kaspa Node on FluxCloud allows you to participate in the Kaspa network with full redundancy, automated failover, and blockchain-backed registration — all managed from an easy-to-use web interface.

Steps​

  1. Access FluxCloud
  1. Find Kaspa Node
  • Open the Marketplace → Applications menu tab.
  • Search for Kaspa and select the KaspaNode for Mainnet, or KaspaTestnet for Testnet.
    • Choose 16GB or 24GB depending on your budget, and usage of the node.
  1. Choose Subscription & Instances
  • Select your preferred subscription duration (starting at $27.20 per month).
  • Choose the number of instances (servers running your Kaspa node).
  • Agree to the Terms of Service, then click the blue Continue arrow at the bottom.
  1. Specify Your Deployment Location [Optional]
  • Specify if you want to only allow certain geolocations to spawn your kapsa node or forbidd certain geolocations.
  • By default your Kaspa node will be deployed on random servers globally .
  • Supported are continent, and additionally Country selection.
  • Save your selection by clicking the + Add Allowed/Forbidden button.
  • Continue using the blue Arrow at the bottom.
  1. Email Notications [Optional]
  • Enter your email address to receive notifications about your game server, including:
    • When your application finishes launching.
    • When the primary server changes.
    • When your app expiration date is approaching.
    • Continue using the blue Arrow at the bottom.
  1. Launching the Application
  • Your application must be signed and registered on the Flux network.
    • Click the Sign and Register button.
    • Sign the message using the pop-up.
      • If you logged in via Google or Email, this step is completed automatically.
  1. Complete Payment
  • Choose your payment method:
    • Fiat: Stripe or PayPal
    • Crypto: FLUX coin (5% discount)
  • Payment is monitored automatically. Once confirmed, your application will be deployed, and a blue Manage button will appear—directing you to your application’s management panel.

⚠️ Important: FLUX Payments

FLUX payments are only accepted via the FLUX Mainnet, not through any of our EVM tokens.

We ALSO strongly recommend not sending FLUX payments from exchanges, as:

  • Transactions or withdrawals may not complete within the required 30-minute window.
  • Many exchanges do not support adding a MEMO, which is required for proper payment processing.

To ensure a smooth transaction, use a compatible multi-chain wallet such as:

  • Zelcore — supports the Kaspa ecosystem (Mainnet, Kasplex, Igra Labs)
  • SSP Wallet — multi-sig wallet for direct FLUX Mainnet payments

With built-in auto-failover, FluxCloud is redundant by design. Each Kaspa Node deployment spins up three independent nodes that automatically fail over if needed, ensuring uptime and stronger decentralization — all for just $27 a month.

How to Manage Your Kaspa Node​

Once deployed, FluxCloud provides all the tools you need to monitor, update, and control your Kaspa Node instances directly from the management dashboard.

Access Your Kaspa Node Logs​

How to Access

Applications → Management → Manage App → Logs

  • Open the Management tab under Applications.
  • Select your KaspaNode from My Active Apps and click Manage.
  • Open the Logs tab.

Backend Selector

At the top right, you’ll find a FluxNode IP selector, allowing you to choose which node instance you want to inspect or control.
Use the reload button to refresh the list of currently active FluxNodes running your app.

Why This Is Useful

  • Troubleshoot issues or monitor node performance.
  • Review startup or sync status messages.
  • Confirm your node is running and connected properly.

Successful Kaspa Node Synced 100%

  • If your Kaspa node is 100% synced you should see logs similar to the example below.

Connect to Your Kaspa Node​

You can connect to your Kaspa Node directly via its public IP and designated ports for peer-to-peer, gRPC, or WRPC access.

How to Find Node IPs:

Applications → Management → Manage App → Running Instances

  • Open the Management tab under Applications.
  • Select your KaspaNode app and click Manage.
  • Go to the Running Instances tab to view your node IPs.

Port Usage:

PortFunction
15111P2P
15110gRPC
17110WRPC-Borsh
18110WRPC-JSON

For testnet connections, replace the middle digit with “2” (e.g., 15211 for P2P).

Example P2P connection:

78.46.37.110:15111

Test your Connection:

You can use the website https://nodes.kaspa.ws/ to verify whether your Kaspa Node is publicly reachable via its P2P port.

  1. Open nodes.kaspa.ws.

  2. Enter one of your FluxNode IP addresses and the P2P port (15111) in the input fields.

  3. Click the Lookup button to test connectivity.

  4. If your node is reachable, you’ll see a confirmation message such as:\

    Success! 65.109.52.141:15111 is a Crescendo compatible public node

Note: It may take up to a couple of hours after deployment for your node to become publicly reachable.

Update or Renew Your Kaspa Node​

How to Access

Applications → Management → Manage App → Global App Management → Update/Renew

  • Open the Management tab under Applications.
  • Select your KaspaNode app from My Active Apps and click Manage.
  • Open the Subscription tab to extend your subscription or update configurations.
