ERC20 Token Launchpad

A React-based dApp that allows users to launch their own ERC20 tokens on Ethereum Mainnet or Sepolia testnet. Built with modern web3 technologies and a clean, user-friendly interface.

Features

• Connect Ethereum wallet (MetaMask and other Web3 wallets)
• Switch between Ethereum Mainnet and Sepolia testnet
• Create custom ERC20 tokens with:
  • Custom token name
  • Custom token symbol
  • Configurable initial supply
• Automatic minting of initial supply to owner's wallet
• Additional token minting functionality to any wallet address
• Real-time network detection and switching
• Responsive UI with shadcn components

Tech Stack

• React + Vite
• Wagmi (Ethereum interactions)
• Viem (Ethereum data fetching)
• TanStack Query (Data management)
• Tailwind CSS (Styling)
• shadcn/ui (UI components)
• Lucide React (Icons)

Prerequisites

• Node.js (v16 or higher)
• npm or yarn
• MetaMask or another Web3 wallet

Installation

1. Clone the repository:

git clone <repository-url>
cd token-launchpad

2. Install dependencies:

npm install

3. Create a .env file in the root directory and add your environment variables:

Usage

1. Connect your Web3 wallet using the "Connect Wallet" button
2. Select your desired network (Ethereum Mainnet or Sepolia)
3. Fill in the token details:
   • Token Name (e.g., "My Token")
   • Token Symbol (e.g., "MTK")
   • Initial Supply (e.g., "1000000")
4. Click "Deploy Token" to launch your token
5. Once deployed, you can mint additional tokens to any address

Smart Contract

The project uses a standard ERC20 implementation with additional minting capabilities. The contract includes:

• Standard ERC20 functionality
• Minting capability for token owner
• Basic security features
• Network agnostic deployment

Security Considerations

• Always test your token on Sepolia testnet first
• Double-check all transaction parameters before confirming
• Keep your private keys secure
• Be cautious with initial supply and minting parameters
