Hardhat Project

Create a crowdfunding campaign where users can pledge funds to and claim funds from the contract.

Your contract(s) should be written such that:

1. Funds take the form of a custom ERC20 token
2. Crowdfunded projects have a funding goal
3. When a funding goal is not met, customers are be able to get a refund of their pledged funds
4. dApps using the contract can observe state changes in transaction logs
5. Optional bonus: contract is upgradeable

This project demonstrates a basic Hardhat use case. It comes with a contract, and a script that deploys that contract.

Functionality

• Code compiles
• Code accomplishes task described in prompt
• Code has no glaring security issues
• Code is readable and organized
• Demonstrates ability to create and use modifiers appropriately
• Demonstrates ability to create and emit events appropriately
• Demonstrates ability to use contract inheritance appropriately
• Demonstrates ability to validate conditions and throw sensible errors
• Demonstrates ability to appropriately use global functions to access information about the transaction, block, address, etc.
• Demonstrates ability to choose appropriate memory types for parameters, variables, etc.
• Smart contract can quickly and easily be run on a local network
• Project demonstrates understanding of common EVM developer tooling, e.g. truffle, ganache, hardhat, etc.
• Project contains basic tests.
• Contract is upgradeable
