📱 Counter DApp

🍀 This project is a simple decentralized counter application (DApp) that demonstrates how to build a full-stack DApp using Next.js, Web3.js, Hardhat, and Polygon zkEVM. Users can interact with the counter by incrementing and decrementing its value through a user-friendly interface. 🍀

👩🏻‍🔧 Technologies

💻 Frontend:

Next.js - A React-based framework for server-rendered applications.

⛓️ Blockchain Interaction:

Web3.js - A JavaScript library for interacting with Ethereum-based blockchains.

📜 Smart Contracts:

Hardhat - A Rust-based smart contract development framework for writing, testing, and deploying contracts.

💜 Blockchain Network:

Polygon zkEVM - A Layer 2 Ethereum-compatible scalable network, utilizing zero-knowledge rollups for efficient and secure transactions.

🧑‍💻 Getting Started

📚 Prerequisites

• Node.js (>= 14.x.x)
• Yarn (>= 1.22.x)
• Hardhat CLI

⬇️ Installation

1. 🛠️ Clone the repository:

   git clone https://github.com/Polygon-Advocates/zkevm-dapp.git && cd zkevm-nextjs-counter-dapp
   

2. 🛠️ Install the frontend dependencies:

   cd frontend && yarn install
   

3. 🛠️ Compile and deploy the smart contract:

   cd ../backend && Hardhat build && Hardhat deploy
   

   Make sure to copy the deployed contract address for the next step.

4. 🛠️ Configure the frontend:

   Create a .env.local file in the frontend directory with the following content:

   NEXT_PUBLIC_CONTRACT_ADDRESS=YOUR_DEPLOYED_CONTRACT_ADDRESS
   
   NEXT_PUBLIC_RPC_URL=YOUR_RPC_URL
   

   Replace YOUR_DEPLOYED_CONTRACT_ADDRESS with the contract address from the previous step, and YOUR_RPC_URL with a valid RPC URL for the Polygon zkEVM network.

5. 🛠️ Run the frontend development server:

   cd ../frontend && yarn dev
   

   The application should now be accessible at http://localhost:3000.
