Supply Chain Blockchain D-App

This Decentralized Application is designed with blockchain technology using solidity, truffle, web3.js and front-end development.

How to Use the D-App

Metamask is necessary to use the app. Make sure you have an account on it. Go to Chrome-extensions to add Metamask.

This project is Deployed on Rinkeby Testnet. Fund your account with some rinkeby test ether to use the D-app. You can visit rinkeby etherscan for previous transaction history that you will have on this D-App.

Below image depicts what the project offers:

Project Images:

Create Item:

Here data is stored in events, refer solidity code for same. Index is item's index, second field is step, where 0 means created, 1 means paid, and 2 means delivered.

Item paid and set to deliver:

Mark Item as Delivered:
