⚖️ AMM (Automated Market Maker)

A lightweight decentralized exchange (DEX) prototype enabling token swaps and liquidity provisioning, built with React, Solidity, and Hardhat, and deployed on the Ethereum Sepolia Testnet.

🌐 Live Demo https://amm-rouge.vercel.app/

📌 Project Overview

This Automated Market Maker (AMM) allows users to seamlessly swap between two dummy ERC-20 tokens, provide liquidity, and view live pricing — all powered by a smart contract using the constant product formula (x * y = k).

🚀 Features

🔁 Swap between two deployed ERC-20 tokens (Sepolia testnet) 💧 Add or remove liquidity from the pool 📊 Real-time charts for price and liquidity via ApexCharts ⚙️ On-chain interaction using Hardhat + ethers.js ⚛️ React frontend with Redux state management 🛠 Tech Stack

Frontend React – UI framework Redux Toolkit – App state management React Router – Navigation ApexCharts – Charting for price/liquidity trends Bootstrap – Responsive UI components Smart Contracts & Blockchain Solidity – Smart contract development Hardhat – Ethereum development environment Ethers.js – Blockchain integration Sepolia Testnet – Deployed test contracts 📦 Installation & Setup

Prerequisites

Node.js & npm installed npm install

Sepolia wallet with test ETH (e.g., via faucet)

Clone & Install

git clone https://github.com/Adz30/AMM.git cd AMM npm install Run Frontend npm start

Deploy Contracts Locally Start a local Hardhat node:

npx hardhat node

Deploy the contracts: npx hardhat run scripts/deploy.js --network localhost

📜 Usage

Connect your wallet (Sepolia network) Swap tokens via the AMM interface Add/remove liquidity to participate in fee rewards Watch the price curve update in real time 🧪 Testing

To run contract tests:

npx hardhat test 📄 License
