ShoppingToken Contract

Overview

The ShoppingToken contract is a basic implementation of a token on the Ethereum blockchain. It allows for minting (creating) and burning (destroying) tokens, managing balances, and keeping track of the total token supply.

Requirements

1. Token Details: The contract stores information about the token, including its name (Name), identifier (ID), and total supply (points).
2. Balance Mapping: It uses a mapping (balances) to track token balances for each address.
3. Mint Function: Allows increasing the total supply and adding tokens to a specific address.
4. Burn Function: Allows decreasing the total supply and removing tokens from a specific address, with checks to ensure the address has sufficient balance.
5. Security: The burn function includes a conditional check to prevent burning more tokens than the sender owns.

Contract Details

Variables

• Name: A public string variable representing the name of the token.
• ID: A public string variable representing an identifier or abbreviation for the token.
• points: A public uint variable representing the total supply of tokens.

Functions

• Constructor: Initializes the token with a name, identifier, and initial supply.
• mint: Function to mint new tokens to a specified address. Increases total supply and recipient's balance.
• burn: Function to burn tokens from a specified address. Decreases total supply and sender's balance, with a check to prevent over-burning.

Usage

To use this contract:

1. Deploy it on an Ethereum-compatible blockchain or online on Remix IDE.
2. Upon deployment, provide values for _name, _ID, and _initialSupply to initialize the token details.
3. Use the mint function to add tokens to specific addresses.
4. Use the burn function to remove tokens from specific addresses, ensuring the sender has enough tokens to burn.

Solidity Version

The contract is implemented in Solidity version 0.8.18.
