EthStarter CrowdFunding Dapp

This is a full stack dapp comprised of Solidity smart contracts for a Eth Kickstarter clone. The project is comprised of:

React SPA scafolded using Create React App
Two Solidity smart contracts. One for projects and the other for the administration of projects.
Hardhart and Ether.js
Unit tests

Implementation

Two smart contracts are contained in the src/contracts folder. These are the:

EthStarter: Factory contract for creating projects.
EthProject: Crowdfunding project contracts that implements a portion of ERC721 for token minting based on contributions.
Two basic unit tests in src/test for both smart contracts. The test coverage is very low and I'll be adding more tests in the future.

Project Brief

The smart contract is reusable; multiple projects can be registered and accept ETH concurrently.
The goal is a preset amount of ETH.
- This cannot be changed after a project gets created.
Regarding contributing:
- The contribute amount must be at least 0.01 ETH.
- There is no upper limit.
- Anyone can contribute to the project, including the creator.
- One address can contribute as many times as they like.
Regarding tiers:
- There are three tiers.
- Bronze tier is granted to anyone contribution.
- Silver tier is granted to a total contribution of at least 0.25 ETH.
- Gold tier is granted to a total contribution of at least 1 ETH.
- Tiers should be granted immediately so other apps can read them.
- "Total contribution" is scoped per-project (like kickstarter).
If the project is not fully funded within 30 days:
- The project goal is considered to have failed.
- No one can contribute anymore.
- Supporters get their money back.
- Tier grants are revoked.
Once a project becomes fully funded:
- No one else can contribute (however, the last contribution can go over the goal).
- The creator can withdraw any percentage of contributed funds.
The creator can choose to cancel their project before the 30 days are over, which has the same effect as a project failing.

Ethereum configuration

To get start, try running some of the following tasks:

npx hardhat accounts
npx hardhat compile
npx hardhat clean
npx hardhat test
npx hardhat node
node scripts/sample-script.js
npx hardhat help

React SPA

Available Scripts

In the project directory, you can run:

`yarn start`

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

`yarn test`

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

`yarn build`

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

`yarn eject`

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
