Decentralized Token System

This is a decentralized application (DApp) built with React and Ethereum smart contracts. The app interacts with a custom smart contract (DecentralizedToken.sol) that implements a simple ERC-20-like token with pausing, minting, transferring, and burning functionalities. Users can connect their wallet, check their token balance, transfer tokens, and burn tokens.

Features

• Connect Wallet: Users can connect their Ethereum wallet (e.g., MetaMask).
• View Balance: Displays the user's current token balance.
• Pause/Unpause: The contract owner can pause or unpause the contract.
• Transfer Tokens: Users can transfer tokens to other addresses.
• Burn Tokens: Users can burn their tokens, reducing the total supply.

Tech Stack

• Frontend: React
• Blockchain: Ethereum (using Solidity)
• Smart Contract: Solidity
• Wallet Integration: MetaMask (via ethers.js)

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/decentralized-token-system.git
   cd decentralized-token-system
   

2. Install dependencies:

   npm install
   

3. Smart Contract Deployment:

The smart contract (PauseToken.sol) should be deployed to the Ethereum network (either a testnet like Rinkeby or the mainnet). You can deploy it using Remix IDE or any other Ethereum development tool.

4. Set up .env file (if required):

   You may need to set up a .env file for configuration (for example, providing the smart contract address, network configurations, etc.).

5. Start the React Token Manager app:

   npm start
   

This will start the React application on http://localhost:3000.

Usage

1. Connect Wallet: Click the "Connect Wallet" button to link your MetaMask wallet with the DApp.
2. Transfer Tokens: Enter the amount you wish to transfer and click "Transfer Tokens" to send tokens to another address.
3. Burn Tokens: Enter the amount of tokens to burn and click "Burn Tokens" to reduce the total supply.
4. Pause/Unpause Contract: The contract owner can pause or unpause the contract by calling the corresponding functions.

Notes

Ensure that you have MetaMask installed and configured to interact with the Ethereum network. The contract is paused by default when the contract owner calls the pause function.

Example Contract Functions

1. Pause: Pauses the contract to prevent token transfers.
2. Unpause: Unpauses the contract to allow token transfers again.
3. Transfer: Transfers tokens from the user's address to another address.
4. Burn: Allows the user to burn their tokens, reducing the total supply.
