DEX - Decentralized Exchange

Overview

Welcome to DEX, a decentralized exchange (DEX) with an Automated Market Maker (AMM) model. This platform allows users to swap ETH for TOKEN and vice versa with a 1% fee. Liquidity providers can supply liquidity and receive LP tokens, which can be burned to withdraw ETH and TOKEN.

Features

• Automated Market Maker (AMM): Facilitates ETH <> TOKEN swaps.
• 1% Swap Fee: Charged on all swaps, distributed to liquidity providers.
• Liquidity Provision: Users can supply liquidity and receive LP tokens.
• Withdraw Liquidity: Burn LP tokens to withdraw ETH and TOKEN.
• Secure and Transparent: Built with Foundry, Wagmi, and Next.js for a robust and user-friendly experience.

Tech Stack

• Solidity: Smart contracts for the AMM and LP functionalities.
• Foundry: Development environment for Solidity.
• Wagmi: React hooks library for Ethereum.
• Next.js: Framework for the frontend.

Installation

1. Clone the repository:

   git clone https://github.com/akhil888binoy/Decentralized-Exchange.git
   cd dex

2. Install dependencies:

   npm install

3. Set up environment variables: Create a .env file in the root directory and add the necessary environment variables.

   PRIVATE_KEY="..."
   RPC_URL="..."
   ETHERSCAN_API_KEY="..."
   
   

4. Compile contracts:

   forge build

5. Deploy contracts: Update scripts/deploy.js with your deployment logic and run:

   forge create --rpc-url $RPC_URL --private-key $PRIVATE_KEY --constructor-args 0x584FB53d1309625112de608567B00f474E7E4172  --etherscan-api-key $ETHERSCAN_API_KEY --verify src/Exchange.sol:Exchange
   

6. Run the development server:

   npm run dev
