HelloStartUp

Secured Ethereum Crowdfunding Platform

HelloStartUp allows you to create and manage campaigns in the Goerli network using Ethereum smart contracts.

The idea was inspired by Kickstarter.

Problem

To Increase Transparency and Prevent Fraudulent Activities that arise around the world of StartUps and Platforms that have till now been developed around it such as Kickstarter. Although stringent measures such as symmetric encryption are in place to make e-payment safe and secure, it is still vulnerable to hacking. Enterprises with in-house e-payment systems must incur additional costs in procuring, installing and maintaining sophisticated payment-security technologies. There is no guarantee that people who post projects on Kickstarter will deliver on their projects, use the money to implement their projects, or that the completed projects will meet backers' expectations. HelloStartUp is a mockup of Kickstarter built using smart contracts written in Solidity.

Solution

Making transaction histories more transparent and secure through the use of Blockchain technology. Because Blockchain is a type of distributed ledger, all network participants share the same documentation as opposed to individual copies. Backers can decide Where to invest and can Acknowledge the requests for money made by the Project Creators through their votes.The creator can only use the money if a minimum number of backers approve a certain request. It will make sure the money is used for Necessities.

The project is a decentralized crowdfunding application, built to solve the problem of money being misused by people, collected using the traditional crowdfunding applications.
Blockchain helped in keeping track of the money collected using the application, and storing it under the control of a piece of code.
Hence not letting the money get into the hands of anyone and removing every possibility of it getting misused. Thus allowing us to reach to a logical solution to the problem in hand.
Same as crowdfunding in the real world, you can create campaigns requiring goal and minimum pledge amount.
The start up can propose how to use money and how much money is needed as a Request.
The start up cannot use money without more than 50% approvers in voting.

Packages utilized:

Next.js - Server Rendered Apps
Web3Js - Ethereum Javascript API
Semantic UI - User Interface

Prerequisites

Metamask browser extension installed and account.
Some ether balance using Goerli Authenticated Faucet.
In the absence of Metamask, HelloStartUp will fall back to using Infura node to access the Goerli network.

Smart Contract

The contract for HelloStartUp is deployed at address 0xd5872c1bC3f375C14B13eA0FA42E72D377A27c58 and is available inside ethereum/contracts. You can explore the deployed contract on TESTNET Goerli (GTH) Blockchain Explorer (Etherscan) at here.
HelloStartUp will interact with the deployed the contract to create campaigns.
Compile, test and deploy contract:

Note: You have to install required packages by running yarn install and set up all the environment variables before doing this step.
```
cd ethereum
yarn compile
yarn test
yarn deploy
```

Running the project

yarn install
yarn dev

Note: The web page runs on http://localhost:3000. Next.js performs server-side rendering of the pages and hot reloading as you make any changes to the code.

Operations

Create Campaign

Startups can create campaign by specifying the goal of their campaign and minimum pledge amount required.
Once the campaign is created, startups become the manager of their campaign and will be able to create requests for the purpose of building up the campaign which need to be approved by the backers.
Any backers below the requirement for the campaign will have their transaction rejected.

View Campaign

Shows details of the campaign such as the address of the account which created the campaign, goal, minimum pledge amount required, campaign current balance, number of people who have pledged for the campaign, and number of requests created by the manager.

Back the Campaign

Allows backers to pledge and back to the campaign.

View Requests

List the requests created by the manager for building up their campaign.
Backers of the campaign can approve requests.

Add Request

The manager of a campaign can create a request which will be fulfilled by the recipient.
Once equal or more than 50% of the campaign backers approve the request, the startups can finalize the payment to the vendor.
