ItemDB Smart Contract

This repository contains a Solidity smart contract named ItemDB that allows users to store, update, and delete item information associated with their Ethereum addresses.

Overview

The ItemDB contract provides basic CRUD (Create, Read, Update, Delete) operations for managing item details. It utilizes a mapping to associate Ethereum addresses with itemInfo structs, which store the item's name, description, and price.

Features

• Store Item: Users can store item details (name, description, and price) associated with their wallet address.
• Update Item: Users can update specific fields of their item information (name, description, or price) with input validation.
• Delete Item: Users can delete their item information.
• String to Uint Conversion: Includes a utility function to convert string representations of numbers to uint256 with input validation.
• Input Validation: Added require statements to validate input parameters when updating an item.
