CrowdEther

It is a website where creators can create a campaign and contributors can fund then with ethereum

This is a project based on ethereum blockchain. For testing purpose I have used rinkeby test network of ethereum instead of the main network.

About the application

The application contains the following pages:

This is the home page of our application where we can see all the campaigns where we can see all the campaigns and get an option to create a new one . CrowdEther - 众醚

In this page we will see the details of a particular campaigns . Details such as :

  • Address of Manager
  • Minimum Contribution (wei)
  • Number of Requests
  • Number of Approvers -Campaign Balance (ether) and we got a Button to Contribute into the campaigns

CrowdEther - 众醚

Here we can see all the request made by manager If the contributers found that the request made by manager of campaign is genuine then they can approve the request , if more than 50% of the contributers have approve the requests then the manager can finalize the request and the ether will transfered to the recipient address . A Add Request button is there through which the campaign manager can create a new requests for spending the balance in the campaign contract. CrowdEther - 众醚

Here we need to fill the details about the request CrowdEther - 众醚

Language/Technology used

  • Next JS
  • Solidity

Dependencies

  • metamask must be installed in the user’s browser so that you can contribute into a campaign .
  • Metamask must be connected to Rinkeby Network
  • You must have react JS , Next JS and Node installed
  • You must have a infura account and from that copy your rinkeby project link
  • Solidity compiler solidity version 0.4.17
  • fs-extra:^9.0.0
  • ganache-cli:^6.9.1
  • mocha:^7.1.1
  • next:^4.1.4
  • react-dom:^16.13.1
  • truffle-hdwallet-provider:0.0.3
  • web3:1.0.0-beta.26
  • semantic-ui-react

How to install:

In the base folder in command line run the following command

  • ganache : npm install --save ganache-cli
  • mocha : npm install --save mocha
  • solidity : npm install --save [email protected]
  • fs-extra : npm install --save fs-extra
  • web3 : npm install --save [email protected]
  • Next JS : npm install --save [email protected] react react-dom
  • semantic-ui-react : npm install --save semantic-ui-react
  • truffle- hd wallet : npm install --save [email protected]

How to run this code :

make the following change in ethereum/web3.js

  1. Paste the infura link in web3.js file const provider = new Web3.providers.HttpProvider( 'https://rinkeby.infura.io/v3/1ec6558. . . .' // paste your infura link here ); web3 = new Web3(provider);

  2. Paste your 12 word pnemonic in ethereum/deploy.js* const provider = new HDWalletProvider( ‘frame apart post kick armed . . . .’ , // paste your ethereum wallet pnemonic here which u got from meta mask ‘https://rinkeby.infura.io/v3/1ecf5b647d9a60 . . .’ // paste your infura rinkeby project link here );

Now in the base folder run npm run dev to start the server

Now goto browser at : http://localhost:3000/

to deploy a total new CrowdEther site

  • goto ethereum folder run node deploy.js
  • now you will get a address at which contract has been deployed in cmd , copy the Address
  • goto ethereum/factory.js const instance = new web3.eth.Contract( JSON.parse(CampaignFactory.interface), '0xC492ae08D078F41F126d06D03F1e78ce1F3Dc2db' // erase the address and paste the address that you got after deploying ); and then again start the server in main directory as npm run dev
