Supply Chain Management Smart Contract

This repository contains a Solidity smart contract for a supply chain management system. The contract allows tracking the lifecycle of products from creation to delivery using the MODE blockchain.

contract deployed on mode: https://sepolia.explorer.mode.network/address/0xb1e52226fB72585BFA3e63bA8Cb12b4D6EeFd255 Token Contract : https://sepolia.explorer.mode.network/address/0x16624074F5cFff83F51E9bA40F1e34FbA6fa90A5

Features

• Product creation with creator's details, name, price, and creation timestamp.
• State management with various states (Created, InTransit, Delivered, Completed).
• Ownership transfer between participants.
• Payment handling using an ERC20 token.
• Shipment history tracking.
• Admin role for managing contract-related actions.

Getting Started

Prerequisites

• Solidity development environment (Truffle, Remix, etc.)
• An ERC20 token contract (for payment handling)

Deployment

1. Deploy the ERC20 token contract on the Ethereum network.
2. Deploy the Supply Chain Management smart contract, providing the address of the deployed ERC20 token contract.

Usage

1. Create a Product: Call the createProduct function to create a new product. Provide the product name and price in ETH.

2. Update State: Call the updateProductState function to update the state of a product. This function should be used to move the product through its lifecycle.

3. Transfer Ownership: Call the transferProductOwnership function to transfer ownership of a product to another address.

4. Update Price: Call the updateProductPrice function (admin-only) to update the price of a product.

5. Make Payment: Call the makePayment function to make a payment for a product using the ERC20 token.

6. Complete Delivery: Call the completeDelivery function to mark the delivery of a product as completed.

7. Complete Product: Call the completeProduct function to mark a product as completed.

8. Get Shipment History: Call the getShipmentHistory function to retrieve the shipment history of a product.
