SupplyChain

The supply chain management system implemented in this project provides a transparent and decentralized solution for tracking the flow of goods or items from creation to delivery. It leverages the power of smart contracts on the Ethereum blockchain to ensure immutability, auditability, and automation of supply chain processes.

Supply Chain Management

This repository contains Solidity smart contracts for implementing a basic supply chain management system on the Ethereum blockchain. It consists of two contracts: ItemManager.sol and Item.sol.

ItemManager.sol

The ItemManager.sol contract manages the supply chain and keeps track of the different steps involved in the process. It allows the creation of new items, triggering of payments, and marking items as delivered. The contract maintains a mapping of items and emits events to track the progress.

To use the ItemManager contract, import it into your project and interact with its functions:

• createItem(string memory _identifier, uint _priceInWei): Creates a new item in the supply chain with the given identifier and price.

• triggerPayment(uint _index): Allows an item contract to trigger the payment step by sending the required amount of Ether. Only the item contract itself can call this function.

• triggerDelivery(uint _index): Marks an item as delivered in the supply chain. This step can only be triggered after the payment step.

Item.sol

The Item.sol contract is imported by ItemManager.sol and handles individual items in the supply chain. It keeps track of the item's price, the amount paid, and the item's index. When an item receives a payment equal to its price, it automatically triggers the triggerPayment function in the ItemManager contract.

To use the Item contract, import it into your project along with the ItemManager contract.

Usage

1. Install the required dependencies and set up your Ethereum development environment.

2. Import the ItemManager.sol and Item.sol contracts into your project.

3. Deploy the ItemManager contract to the Ethereum network.

4. Interact with the deployed ItemManager contract using a blockchain client, such as Remix or Truffle, or by calling its functions programmatically using a web3 library.

5. Monitor the emitted events to track the progress of the supply chain and ensure that items are created, paid for, and marked as delivered correctly.
