Standard Guide: How to Host an XDC Masternode

Vinn — Tue, 07 Apr 2026 05:55:36 +0000

This guide walks you through the end-to-end steps to host an XDC Network Masternode — whether you’re using:

Private Key / Mnemonic phrase
Fireblocks/Other Wallet via WalletConnect v2
XDCPay / Keystore or browser wallets

From server setup, wallet login, KYC submission, staking, to node activation.

What Is an XDC Masternode?

An XDC Masternode is a validating node that:

Helps secure and validate the XDC blockchain
Participates in consensus and block production
Earns rewards for active participation
Requires a minimum 10,000,000 XDC stake locked for staking
Must submit KYC and be approved on the Masternode App to be active.

Prerequisites

Before you begin:
🗂 Node Server

Deploy your masternode on a remote server (recommended):
✔ Ubuntu 20.04 / 22.04 LTS
✔ Docker / Script-based setup
✔ Public IP and stable internet

Wallet & Funds

You also need:
✔ A wallet holding at least 10,000,000 XDC
✔ The wallet’s private key or mnemonic phrase (if using non-custodial login)
✔ KYC document in PDF format (signed and verifiable)

Coinbase address

This is your masternode identity on the chain.

Coinbase address: Your node’s validator address, generated when setting up your masternode server.

Example format:
xdc……………………………………b

⚠️ Important:

This is NOT your wallet address
It is your masternode server’s coinbase address

Step-by-Step Masternode Hosting

OPTION 1: Hosting Using Docker

This method is ideal for developers and advanced users who want more control.

Step 1: Clone repository

git clone https://github.com/XinFinOrg/XinFin-Node.git

Enter XinFin-Node directory

cd XinFin-Node

Step 2: Install Docker & Update .env file with details

sudo apt update
sudo ./setup/install_docker.sh

Create .env file by using the sample - .env.example

Enter either your company or product name in the INSTANCE_NAME field.

Enter your email address in CONTACT_DETAILS field.

cd mainnet # testnet
cp env.example .env
nano .env

Step 3: Start your Node

For Mainnet

Run:

docker compose -f docker-compose.yml up -d

Your coinbase address can be found in xdcchain/coinbase.txt file.

To stop the node or if you encounter any issues use:

docker compose -f docker-compose.yml down

OPTION 2: Hosting Using Bootstrap Script

This is the recommended and easiest method for most users.

Step 1: Run Bootstrap Script

sudo su -c "bash <(wget -qO- https://raw.githubusercontent.com/XinFinOrg/XinFin-Node/master/setup/bootstrap.sh)" root

Choose mainnet when prompted
Name your node
This generates your node environment and Coinbase address
Always back up private key/keystore

Visit the Masternode App

Go to the official Masternode app:

🔹 Mainnet: https://mn.xinfin.network
🔹 Testnet: https://mn.apothem.network

Click Login to begin.

Choose a Login Method

LOGIN OPTION 1 — Private Key | Mnemonic Phrase

Select Private Key / Mnemonic from the network provider list
Paste your wallet’s private key or mnemonic phrase securely
Approve login to the Masternode App

⚠️ Keep this phrase secure — anyone with it controls your funds and stake.

LOGIN OPTION 2 — WalletConnect (Fireblocks / Other Wallets)

A. Fireblocks Flow

Select WalletConnect v2 as Network Provider
A QR code appears for Fireblocks Web3 Wallet
Open your Fireblocks Web3 Wallet
Scan the QR and Connect Vault to dApp
Choose your vault account (with ≥10M XDC)
Click Connect vault

Fireblocks will manage your keys securely, and your Masternode app access is approved through WalletConnect.

This method lets you keep keys in institutional custody and apply governance rules via Fireblocks Policy Engine.

Additional Wallet Options

Other wallets like XDCPay or browser wallets can also be used — simply select them and connect.

Become a Candidate

Once connected/logged in:

Click Become a Candidate

Upload your KYC PDF

📌 Your KYC must be signed by a verifiable authority (e.g., notary, lawyer, company secretary).

Enter Coinbase Address & Apply

In the staking form:

Enter the Coinbase address you generated on your masternode server
This links your on-chain node identity to your staked wallet
Click Apply

Your wallet (Fireblocks or private key login) will prompt you to approve the staking transaction.

Approve & Confirm Staking

The Masternode App will send a transaction to:
✔ Lock 10,000,000 XDC in the node contract
✔ Confirm your node proposal on chain

Depending on your wallet, approve it:

If using Fireblocks: Fireblocks verifies with your Policy Engine rules
If using private key/mnemonic: Sign the transaction locally securely

Verification & Active Status

Once the stake transaction confirms:
✔ Your masternode proposal has been submitted
✔ The node enters the round-robin selection pool
✔ After acceptance, your node becomes active and earns block rewards

Use a block explorer (e.g., xdcscan) to track the transaction & status.

Best Practices for Key + Wallet Security

Private Key / Mnemonic

Keep keys offline in secure vaults
Do not store keys in plain documents
Use hardware wallets if possible

Fireblocks Custodial Login

Keys are held in MPC hardware enclaves
Fireblocks Policy Engine enforces transaction governance
Requires admin approvals for sensitive transactions

This adds a strong enterprise-grade layer of protection.

If you’re unsure about the difference between key-based accounts and smart contract accounts, please take a look at this page.

In this example, we simply create a key-based wallet with ethers.js like so:

const randomWallet = ethers.Wallet.createRandom();
const privateKey = randomWallet.privateKey;
Set the privayeKey in the .env : WALLET_PRIVATE_KEY
set the apiKey in .env: API_KEY

Then we use this key-based wallet to instantiate the SDK on XDC Network and get the wallet address.

const chainId = 50;
const modularSdk = new ModularSdk({ privateKey: process.env.WALLET_PRIVATE_KEY }, 
{ chainId: chainId, 
bundlerProvider: new EtherspotBundler(chainId, 
bundlerApiKey, customBundlerUrl) }) 
const address: string = await primeSdk.getCounterFactualAddress();
console.log(address);

4.Send funds to another address
Getting all together into a function

import { EtherspotBundler, ModularSdk, MODULE_TYPE, printOp, sleep } from '@etherspot/modular-sdk';
import * as dotenv from 'dotenv';

const recipient = ''; // recipient wallet address
const value = '0.0000001'; // transfer value
const bundlerApiKey = process.env.API_KEY;
const privateKey = process.env.WALLET_PRIVATE_KEY;

// initializating sdk...
const modularSdk = new ModularSdk({ privateKey: process.env.WALLET_PRIVATE_KEY },
{ chainId: Number(process.env.CHAIN_ID),
bundlerProvider: new EtherspotBundler(Number(process.env.CHAIN_ID), bundlerApiKey) })
console.log('address: ', modularSdk.state.EOAAddress)

// get address of EtherspotWallet...
const address: string = await modularSdk.getCounterFactualAddress();
console.log('\x1b[33m%s\x1b[0m', `EtherspotWallet address: ${address}`);

// clear the transaction batch
await modularSdk.clearUserOpsFromBatch();

// add transactions to the batch
const transactionBatch = await modularSdk.addUserOpsToBatch({ to: recipient, value: ethers.utils.parseEther(value) });
console.log('transactions: ', transactionBatch);

// get balance of the account address
const balance = await modularSdk.getNativeBalance();
console.log('balances: ', balance);

// estimate transactions added to the batch and get the fee data for the UserOp
const op = await modularSdk.estimate();
console.log(`Estimate UserOp: ${await printOp(op)}`);

// sign the UserOp and sending to the bundler...
const uoHash = await modularSdk.send(op);
console.log(`UserOpHash: ${uoHash}`);

// get transaction hash...
console.log('Waiting for transaction...');
let userOpsReceipt = null;
const timeout = Date.now() + 60000; // 1 minute timeout
while ((userOpsReceipt == null) && (Date.now() < timeout)) {
await sleep(2);
userOpsReceipt = await modularSdk.getUserOpReceipt(uoHash);
}
console.log('\x1b[33m%s\x1b[0m', `Transaction Receipt: `, userOpsReceipt);

The XDC Network has introduced a subnet feature, enabling developers to deploy private and customizable blockchain networks within the XDC ecosystem. These subnets provide enhanced privacy, scalability, and flexibility, making them ideal for enterprises and developers seeking an isolated blockchain environment for specific use cases. Here’s a comprehensive guide on setting up and deploying an XDC Subnet.

Prerequisites for Launching an XDC Subnet

To set up an XDC Subnet, ensure that your system meets the following requirements:

Operating System:

Linux: Supported for full deployment.
Mac: Supported only for single-machine testing environments.

Software Dependencies:

Docker and Docker Compose V2 are required. For detailed installation instructions, refer to the Docker Compose documentation for Linux: Docker Compose Install Guide.

Hardware Requirements:

CPU: Minimum 2 cores.
Memory: Minimum 4 GB RAM per subnet node.

Web3 Wallet:

A Web3 wallet with funds is required. For testing, XDC Network provides faucets to obtain test tokens:
XDC Faucet on Apothem Network
BlocksScan Faucet

Step-by-Step Guide to Generate XDC Subnet Configurations Using UI

Once prerequisites are set, you can generate the necessary configuration files for the XDC Subnet.

Step 1: Create a Directory and Download the Configuration Generator Script

Create a new directory for your subnet files. For instance, let’s name it “XDCSubnet”:

mkdir XDCSubnet
cd XDCSubnet

Download the generate.sh script from XDC’s official GitHub repository:

curl -O https://raw.githubusercontent.com/XinFinOrg/XinFin-Node/master/subnet/deployment-generator/scripts/generate.sh

Step 2: Run the Configuration Generator Script

Make the downloaded script executable:

chmod +x generate.sh

Execute the script to launch the local configuration server:

./generate.sh

Step 3: Access the Local Webserver UI

Open a web browser and go to http://localhost:5210/ for local setup. If you’re on a remote server, use http://your_ip_address:5210/.
This interface allows you to enter and customize your subnet configurations according to your specific requirements.

Step 4: Configure Subnet Settings

Enter the necessary details in the form for configuring your subnet (e.g., name, nodes, and any custom options).
Submit the form, and upon successful configuration, you’ll receive a confirmation message on the same screen: “Config Generation Success. Please follow instructions in generated/commands.txt.”

Check the server console for a final message confirming the success of the subnet configuration with “subnet generation successful.”

Once the Subnet generation successfully done, Change the directory to “/generated”

Step 5: Deploy the XDC Subnet

With the configuration set up, proceed with the deployment steps detailed in commands.txt.

Open the commands.txt file using:

nano commands.txt

Copy the commands to a notepad, then execute them step-by-step as instructed. Below is a general overview:

Note: Please refer your updated commands.txt file

1. Deploy Subnet Nodes:

docker compose --env-file docker-compose.env --profile machine1 pull
docker compose --env-file docker-compose.env --profile machine1 up -d

2. Confirm the Subnet is Running (after 60 seconds):

./scripts/check-mining.sh

Resetting the Subnet If Mining Does Not Start

Error:

“Getting latest block
No block has been mined; please check if nodes are peering properly.”

If you encounter an above issue where the subnet is not mining, you can try resetting it with the following commands:

Stop the subnet nodes:

docker compose --env-file docker-compose.env --profile machine1 down

Remove any existing bootnode and chain data to ensure a fresh start:

rm -r bootnodes
rm -r xdcchain*

Restart the subnet nodes:

docker compose --env-file docker-compose.env --profile machine1 up -d

This should reset the subnet and allow mining to begin.

3. Deploy Checkpoint Smart Contract (CSC)

docker pull xinfinorg/csc:v0.2.1
docker run - env-file contract_deploy.env - network generated_docker_net xinfinorg/csc:v0.2.1 full

4. Add CSC Configuration to common.env:

Copy the CHECKPOINT_CONTRACT output from Step 3 and add it to common.env.

Note: If you are running the subnet on a server, ensure you update the common.env file. Replace 127.0.0.1 with the server's IP address to ensure proper connectivity and functionality.

This step is critical for accessing the frontend and related services remotely.

To access common.env file enter:

nano common.env

5. Start services (relayer, backend, frontend)

docker compose - env-file docker-compose.env - profile services pull
docker compose - env-file docker-compose.env - profile services up -d

6. Confirm Subnet services through browser UI

Frontend: http://127.0.0.1:5214
Relayer: http://127.0.0.1:5215

Note: Replace 127.0.0.1 with the server's IP address to ensure proper connectivity and functionality.
