Web3 Linea Marketplace

This is a decentralized marketplace application built using Next.js for the frontend and Hardhat for the blockchain backend. The smart contract is deployed on the Linea testnet.

Getting Started

Prerequisites

Make sure you have the following installed:

• Node.js
• pnpm
• Hardhat
• Infura account for API keys
• A wallet for private key (e.g., MetaMask)

Clone the repository

git clone https://github.com/meowyx/web3-marketplace-linea.git
cd web3-linea-marketplace

Install dependencies

Navigate to the root of the repository and run:

pnpm install

This will install the necessary dependencies for both the frontend and the blockchain packages.

File Structure

packages
├── site          # Frontend built with Next.js, Tailwind CSS, and ShadCN UI
└── blockchain    # Smart contracts using Hardhat

Frontend (Site)

The frontend is located in the packages/site directory and is built with:

• Next.js: A React framework for server-side rendering and static website generation.
• Tailwind CSS: Utility-first CSS framework.
• ShadCN UI: A UI component library.

To run the frontend locally:

cd packages/site
pnpm dev

This will start the development server for the frontend.

Backend (Blockchain)

The smart contracts are located in the packages/blockchain directory. The smart contract logic is written in Solidity, and Hardhat is used as the development environment.

.env Variables

Before deploying the smart contract, make sure to update the .env file in the packages/blockchain directory with the following values:

# Infura API key for connecting to Ethereum networks
INFURA_API_KEY=your_infura_api_key_here

# Private key of the account to be used for deployments and transactions
ACCOUNT_PRIVATE_KEY=your_account_private_key_here

Deploy the Smart Contract

To deploy the smart contract to the Linea testnet, run the following command:

npx hardhat ignition deploy ignition/modules/Marketplace.ts --network linea-testnet

This will deploy the marketplace smart contract on Linea Sepolia.
