OnChainNFT Project

This project implements an on-chain NFT using Solidity, Hardhat, and OpenZeppelin. The NFT metadata, including an SVG image, is stored entirely on the blockchain.

Features

• On-Chain Metadata: The NFT metadata is stored on-chain, including the SVG image.
• Minting Functionality: Users can mint new NFTs.
• ERC-721 Standard: The contract is based on OpenZeppelin's ERC-721 implementation.
• Hardhat Deployment: The project uses Hardhat for contract compilation, testing, and deployment.
• Base Sepolia Testnet: The contract is deployed on the Base Sepolia testnet.
• Etherscan Verification: Configured for contract verification on BaseScan.
• Automated Deployment & Minting: Deployment, minting, and verification are handled in a single Ignition script.

Prerequisites

Before running the project, ensure you have the following installed:

• Node.js (>=16.x)
• Hardhat
• Alchemy or Infura API key
• Base Sepolia testnet account with funds

Installation

1. Clone the repository:

   git clone https://github.com/7maylord/OnchainNFT
   cd OnChainNFT

2. Install dependencies:

   npm install

3. Create a .env file and configure it:

   ALCHEMY_BASE_SEPOLIA_API_KEY_URL=<your-alchemy-url>
   ACCOUNT_PRIVATE_KEY=<your-wallet-private-key>
   BASESCAN_API_KEY=<your-basescan-api-key>

Compilation

Compile the smart contracts:

npx hardhat compile

Deployment, Minting & Verification

Deployment, minting, and contract verification are handled automatically by the Hardhat Ignition module:

npx hardhat ignition deploy ignition/modules/OnChainNFT.ts --network base_sepolia --verify

Testing

Run tests using Hardhat:

npx hardhat test
