This comprehensive example demonstrates how to build a production-ready NFT platform on the Nexus blockchain:

Live Demo: https://nexus-nft-example.vercel.app/
GitHub: https://github.com/nexus-xyz/nexus-nft-example

Overview

This project showcases a modern, full-stack NFT platform built with Next.js 13+ (App Router), TypeScript, Hardhat, and ethers.js v6. It demonstrates:

ERC-721 compliant NFT smart contract with metadata management
Next.js frontend with App Router architecture
Firebase Storage integration for NFT image hosting
OpenSea-compatible metadata API
Wallet integration with MetaMask
Vercel deployment pipeline

The application allows users to:

Create and deploy custom NFT collections
Upload and manage collection artwork
Mint NFTs to any address
View and transfer owned NFTs
Update collection metadata (when not frozen)

Setting Up Your Development Environment

1. Install Required Tools

# Install Node.js and npm if not already installed
# Then install Hardhat
npm install --save-dev hardhat

Hardhat is a development environment and task runner for Ethereum that helps developers compile, deploy, test, and debug smart contracts. The —save-dev flag ensures Hardhat is installed as a development-only dependency, keeping it separate from production dependencies.

2. Create a New Project

# Create a new directory
mkdir contract
cd contract

# Initialize a Node.js project with package.json
npm init -y

# Initialize a new Hardhat project
npx hardhat

3. Configure Hardhat for Nexus

Within your project directory, create/update your config file hardhat.config.js which will define the network configuration, RPC endpoint for Hardhat to connect to, and chainID for signature verification:

require("dotenv").config();
require("@nomicfoundation/hardhat-toolbox");

module.exports = {
  solidity: "0.8.20",
  networks: {
    nexus: {
      chainId: 3940,
      accounts: process.env.PRIVATE_KEY ? [process.env.PRIVATE_KEY] : []
    }
  }
};

4. Configure your private key in .env file

Get your private key from Nexus
- Go to the Nexus Web App
- Sign in to your account in the top right corner
- Click the “Settings” tab
- Navigate to “Account & Security”
- Click on “Private Key”
- Click “Reveal” to view your private key
Create your .env file
- Create a new file named .env in your project root directory
- Add your private key in this format:
```
PRIVATE_KEY=your_private_key_here
```
Install dotenv package
```
npm install dotenv
```
Update hardhat.config.js
- Add this line at the top of your hardhat.config.js if not already present:
```
require("dotenv").config();
```

Important Security Notes:

Never share your private key
Never commit it to version control
Keep it secure and backed up
Use a test account for development

5. Receive test NEX from a faucet for contract deployment

To deploy your contract on Nexus Layer 1, you’ll need NEX tokens to pay for gas fees. Gas fees are the cost of executing transactions on the blockchain, similar to how you need fuel to drive a car. There are two ways to receive NEX for testing:

Earn NEX through Proving
- Submit proofs to earn points and NEX in real-time
- This is the recommended way as it helps secure the network
- For detailed instructions on proving, visit our Proving Guide
Use the Nexus Faucet
- A faucet is a service that provides small amounts of cryptocurrency for testing.
- It’s like a water faucet, but instead of water, it dispenses test tokens
- Visit our Faucet to receive test NEX

Note: The amount of NEX you receive from the faucet is sufficient for deploying and testing basic contracts. For more extensive testing, consider earning NEX through proving.

Smart Contract Architecture

1. Create a Contract File

Create contracts/SimpleNFT.sol. The project uses an advanced ERC-721 implementation with enhanced metadata management, tailored for NFT collections requiring scalable minting, secure update mechanisms, and compatibility with modern NFT marketplaces.

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;

import "@openzeppelin/contracts/token/ERC721/ERC721.sol";
import "@openzeppelin/contracts/token/ERC721/extensions/ERC721URIStorage.sol";
import "@openzeppelin/contracts/interfaces/IERC4906.sol";
import "@openzeppelin/contracts/access/Ownable.sol";

contract SimpleNFT is ERC721, ERC721URIStorage, IERC4906, Ownable {
    uint256 private _nextTokenId;
    string public baseURI;
    bool public metadataFrozen;

    event MetadataFrozen();

    constructor(
        string memory name,
        string memory symbol,
        string memory _baseURI
    ) ERC721(name, symbol) Ownable(msg.sender) {
        baseURI = _baseURI;
    }

    function _baseURI() internal view override returns (string memory) {
        return baseURI;
    }

    function setBaseURI(string memory _newBaseURI) public onlyOwner {
        require(!metadataFrozen, "Metadata is frozen");
        baseURI = _newBaseURI;
        emit BatchMetadataUpdate(0, type(uint256).max);
    }

    function freezeMetadata() public onlyOwner {
        metadataFrozen = true;
        emit MetadataFrozen();
    }

    function safeMint(address to) public returns (uint256) {
        uint256 tokenId = _nextTokenId++;
        _safeMint(to, tokenId);
        return tokenId;
    }

    function batchMint(address to, uint256 quantity) public returns (uint256[] memory) {
        uint256[] memory tokenIds = new uint256[](quantity);
        for (uint256 i = 0; i < quantity; i++) {
            tokenIds[i] = safeMint(to);
        }
        return tokenIds;
    }

    // Override required functions
    function tokenURI(uint256 tokenId) public view override(ERC721, ERC721URIStorage) returns (string memory) {
        return super.tokenURI(tokenId);
    }

    function supportsInterface(bytes4 interfaceId) public view override(ERC721, ERC721URIStorage) returns (bool) {
        return interfaceId == type(IERC4906).interfaceId || super.supportsInterface(interfaceId);
    }
}

This contract, SimpleNFT, extends the ERC-721 standard to support modern NFT use cases including batch minting, dynamic metadata with optional freezing, and ERC-4906 metadata update events. It is built atop OpenZeppelin libraries for security and standard compliance.

Key Features

ERC-721 Compliance Inherits from OpenZeppelin’s ERC721 and ERC721URIStorage, enabling both standard NFT transfer and ownership logic and per-token URI storage. Batch Minting Allows efficient minting of multiple NFTs in a single transaction. Useful for creators distributing large collections or performing airdrops. Metadata Control and Freezing The base URI can be updated by the owner until freezeMetadata() is called. Once frozen, metadata becomes immutable, which is critical for collectors and marketplaces relying on permanent content. ERC-4906 Support Implements the ERC-4906 interface, which allows external platforms to detect when metadata has changed. The setBaseURI method emits a BatchMetadataUpdate event covering all tokens. Ownership and Access Control Relies on OpenZeppelin’s Ownable pattern to restrict administrative functions (setBaseURI, freezeMetadata) to the contract owner. Gas Efficiency Uses a simple incrementing counter (_nextTokenId) to assign token IDs, reducing storage complexity and minimizing gas costs. Batch minting via loops avoids external calls, maintaining compact logic.

Function Breakdown

Function	Description
`constructor(...)`	Initializes contract with name, symbol, and base URI; sets ownership
`_baseURI()`	Internal getter for the stored `baseURI`
`setBaseURI(...)`	Allows the owner to update metadata base URI; emits ERC-4906 update signal
`freezeMetadata()`	Permanently disables URI updates and emits a `MetadataFrozen` event
`safeMint(...)`	Mints a single token to the specified address
`batchMint(...)`	Mints multiple tokens to a single address and returns all token IDs
`tokenURI(...)`	Resolves the final token URI using base URI or stored value
`supportsInterface(...)`	Advertises interface support for ERC-721, metadata extension, and ERC-4906

This architecture is designed for secure, efficient NFT issuance with full compatibility across platforms and immutable metadata enforcement when required.

2. Create a Deployment Script

Create scripts/deploy.js: A deployment script is a programmatic way to deploy your smart contracts to a blockchain using Hardhat. Instead of manually interacting with the network through a UI or console, deployment scripts allow you to:

Automate contract deployment
Set constructor arguments dynamically
Log or save deployed addresses
Chain deployments in a predictable order
Integrate easily into testing, development, or CI/CD pipelines

Here we create a new folder entitled scripts and create a file entitled deploy.js, which will deploy our code to the Layer 1:

import { ethers } from "hardhat";
import dotenv from "dotenv";
import { SimpleNFT__factory } from "../typechain-types";

dotenv.config();

async function main() {
  try {
    console.log("Starting SimpleNFT deployment...");

    const [deployer] = await ethers.getSigners();
    console.log("Deploying contracts with account:", deployer.address);

    // Verify environment variables
    const apiUrl = process.env.NEXT_PUBLIC_API_URL;
    if (!apiUrl) {
      throw new Error("NEXT_PUBLIC_API_URL environment variable is not set");
    }

    // Ensure the API URL ends with a trailing slash
    const baseUri = `${apiUrl.replace(/\/$/, '')}/api/metadata/`;
    
    console.log("Using metadata base URI:", baseUri);

    const SimpleNFT = await ethers.getContractFactory("SimpleNFT");
    console.log("Contract factory initialized");

    const nft = await SimpleNFT.deploy(
      "Nexus NFT Collection",  // name
      "NNFT",                 // symbol
      baseUri                 // baseTokenURI
    );

    await nft.waitForDeployment();
    const address = await nft.getAddress();

    console.log("SimpleNFT deployed to:", address);
    console.log("Transaction hash:", nft.deploymentTransaction()?.hash);

    // Log deployment details
    console.log({
      contractAddress: address,
      deployer: deployer.address,
      network: (await ethers.provider.getNetwork()).name,
      blockNumber: await ethers.provider.getBlockNumber()
    });

    // Log verification command
    console.log("\nTo verify on block explorer:");
    console.log(`npx hardhat verify --network nexus ${address} "Nexus NFT Collection" "NNFT" "${baseUri}"`);

    // Optional: Mint first NFT to deployer
    const mintTx = await nft.mint();
    await mintTx.wait();
    console.log("\nFirst NFT minted to deployer");
    console.log("Metadata URL:", `${baseUri}1`);

    console.log("Deployment completed successfully");
  } catch (error) {
    console.error("Deployment failed:", error);
    process.exitCode = 1;
  }
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

This script demonstrates a complete, real-world deployment pattern:

It manages asynchronous deployment logic with await
Provides helpful logs to track progress
Prepares for contract verification on Nexus Explorer

Deploying Your Contract

1. Deploy to Nexus

Run the following command to deploy your contract to the Nexus network:

npx hardhat run scripts/deploy.js --network nexus

You should see the following output in your terminal:

Deploying Counter contract...
Counter contract deployed to: 0x...  # Your contract's address will appear here

This means your contract has been successfully deployed to the Nexus network. Save the contract address - you’ll need it to interact with your contract later.

2. Examine Counter contract on the Nexus Explorer

Visit the Testnet III Nexus Explorer to view your deployed contract. The block explorer is a search engine for the blockchain that lets you:

View all transactions
Check contract code
Monitor contract interactions
Track token transfers
View account balances

To find your contract:

Copy your contract’s address from the deployment output
Paste it into the search bar at the top of the explorer
Click on your contract to view its details

You’ll see:

Contract code (verified)
Transaction history
Contract balance
Recent interactions
Event logs

This is where you can verify that your contract was deployed correctly and monitor its activity on the network.

Setting Up Firebase Storage

The platform uses Firebase Storage for hosting NFT images. Here’s how to set it up:

1. Create a Firebase Project

Go to the Firebase Console
Click “Add project” and follow the setup wizard
Enable Firebase Storage in your project

2. Configure Security Rules

Set up proper security rules for your Firebase Storage:

rules_version = '2';
service firebase.storage {
  match /b/{bucket}/o {
    match /collections/{collectionId}/{allPaths=**} {
      // Allow read access to everyone
      allow read;
      
      // Allow write access only to authenticated users
      allow write: if request.auth != null 
                   && request.resource.size < 5 * 1024 * 1024
                   && request.resource.contentType.matches('image/.*');
    }
  }
}

3. Add Firebase Configuration

Create a .env.local file in the frontend directory:

NEXT_PUBLIC_FIREBASE_API_KEY=your_api_key
NEXT_PUBLIC_FIREBASE_AUTH_DOMAIN=your_project.firebaseapp.com
NEXT_PUBLIC_FIREBASE_PROJECT_ID=your_project_id
NEXT_PUBLIC_FIREBASE_STORAGE_BUCKET=your_bucket.appspot.com
NEXT_PUBLIC_FIREBASE_MESSAGING_SENDER_ID=your_sender_id
NEXT_PUBLIC_FIREBASE_APP_ID=your_app_id
NEXT_PUBLIC_FIREBASE_MEASUREMENT_ID=your_measurement_id

4. Initialize Firebase in Your Application

// src/lib/firebase.ts
import { initializeApp } from 'firebase/app';
import { getStorage } from 'firebase/storage';

const firebaseConfig = {
  apiKey: process.env.NEXT_PUBLIC_FIREBASE_API_KEY,
  authDomain: process.env.NEXT_PUBLIC_FIREBASE_AUTH_DOMAIN,
  projectId: process.env.NEXT_PUBLIC_FIREBASE_PROJECT_ID,
  storageBucket: process.env.NEXT_PUBLIC_FIREBASE_STORAGE_BUCKET,
  messagingSenderId: process.env.NEXT_PUBLIC_FIREBASE_MESSAGING_SENDER_ID,
  appId: process.env.NEXT_PUBLIC_FIREBASE_APP_ID,
  measurementId: process.env.NEXT_PUBLIC_FIREBASE_MEASUREMENT_ID
};

const app = initializeApp(firebaseConfig);
export const storage = getStorage(app);

OpenSea-Compatible Metadata API

The platform includes an API that generates OpenSea-compatible metadata:

// src/app/api/metadata/[tokenId]/route.ts
import { NextRequest, NextResponse } from 'next/server';
import { getFirebaseImageUrl, generateSVG } from '@/lib/images';

export async function GET(
  request: NextRequest,
  { params }: { params: { tokenId: string } }
) {
  const tokenId = params.tokenId;
  const collectionAddress = request.nextUrl.searchParams.get('collection');
  
  if (!collectionAddress) {
    return NextResponse.json({ error: 'Collection address is required' }, { status: 400 });
  }

  try {
    // Try to get the uploaded image URL
    const imageUrl = await getFirebaseImageUrl(collectionAddress, tokenId);
    
    // Generate metadata with OpenSea-compatible format
    const metadata = {
      name: `NFT #${tokenId}`,
      description: "A unique NFT on the Nexus blockchain",
      image: imageUrl || `${process.env.NEXT_PUBLIC_WEBSITE_URL}/api/image/${tokenId}?collection=${collectionAddress}`,
      external_url: `${process.env.NEXT_PUBLIC_WEBSITE_URL}/collection/${collectionAddress}/${tokenId}`,
      attributes: [
        {
          trait_type: "Token ID",
          value: tokenId
        },
        {
          trait_type: "Collection",
          value: collectionAddress
        }
        // Additional attributes can be added here
      ]
    };
    
    // Set cache headers for better performance
    return NextResponse.json(metadata, {
      headers: {
        'Cache-Control': 'public, max-age=3600',
        'Content-Type': 'application/json'
      }
    });
  } catch (error) {
    console.error('Error generating metadata:', error);
    return NextResponse.json({ error: 'Failed to generate metadata' }, { status: 500 });
  }
}

This API follows OpenSea’s metadata standards, including:

Proper naming and description
Image URL (either from Firebase or a generated SVG)
External URL for viewing the NFT
Attributes as traits

Frontend Integration with ethers.js v6

The frontend uses ethers.js v6 to interact with the smart contract:

// src/hooks/useNFT.ts
import { useState, useEffect } from 'react';
import { ethers } from 'ethers';
import SimpleNFTAbi from '@/abi/SimpleNFT.json';

export function useNFT(contractAddress: string | null) {
  const [provider, setProvider] = useState<ethers.BrowserProvider | null>(null);
  const [signer, setSigner] = useState<ethers.Signer | null>(null);
  const [contract, setContract] = useState<ethers.Contract | null>(null);
  const [account, setAccount] = useState<string | null>(null);
  const [chainId, setChainId] = useState<number | null>(null);
  const [isNexusNetwork, setIsNexusNetwork] = useState<boolean>(false);
  
  // Connect wallet
  async function connectWallet() {
    if (!window.ethereum) {
      alert('Please install MetaMask to use this application');
      return;
    }
    
    try {
      const provider = new ethers.BrowserProvider(window.ethereum);
      const network = await provider.getNetwork();
      setChainId(Number(network.chainId));
      setIsNexusNetwork(Number(network.chainId) === 1337); // Replace with actual Nexus chainId
      
      await window.ethereum.request({ method: 'eth_requestAccounts' });
      const signer = await provider.getSigner();
      const address = await signer.getAddress();
      
      setProvider(provider);
      setSigner(signer);
      setAccount(address);
      
      if (contractAddress) {

          contractAddress,
          SimpleNFTAbi.abi,
          signer
        );
        setContract(nftContract);
      }
    } catch (error) {
      console.error('Error connecting wallet:', error);
    }
  }
  
  // Switch to Nexus network
  async function switchToNexus() {
    if (!window.ethereum) return;

      });
    } catch (error) {
      console.error('Error switching network:', error);
    }
  }
  
  // Deploy new collection
  async function deployCollection(name: string, symbol: string, baseURI: string) {
    if (!signer) return null;

  async function mintNFT(to: string) {
    if (!contract || !signer) return null;
    
    try {
      const tx = await contract.safeMint(to);
      const receipt = await tx.wait();
      
      // Parse logs to get the token ID
      const transferEvent = receipt.logs.find(
        (log: any) => log.topics[0] === ethers.id('Transfer(address,address,uint256)')
      );
      
      if (transferEvent) {
        const tokenId = ethers.toBigInt(transferEvent.topics[3]);
        return tokenId.toString();
      }
      return null;
    } catch (error) {
      console.error('Error minting NFT:', error);
      return null;
    }
  }
  
  // Additional functions for batch minting, metadata updates, etc.
  
  return {
