EthFund

EthFund is a decentralized funding platform built on the Ethereum blockchain that allows users to contribute Ether (ETH) to projects or individuals. The smart contract leverages Chainlink price feeds to ensure contributions meet a minimum USD threshold. It is built using Solidity and utilizes OpenZeppelin's libraries for secure and efficient smart contract development.

make deploy ARGS="--network sepolia"

Usage

Funding a Project

Users can fund a project by sending Ether (ETH) to the contract. The contract ensures the minimum contribution amount is met.

function fund() public payable whenNotPaused {
    require(msg.value >= MINIMUM_USD, "You need to spend more ETH!");
    // Function logic...
}

Withdrawing Funds

Only the contract owner can withdraw funds from the contract.

function withdraw() public payable onlyOwner nonReentrant whenNotPaused {
    // Function logic...
}

Testing

Run tests to ensure the contract functions as expected.

make test

Limitations

• The contract only supports contributions in ETH. It does not allow for contributions in other cryptocurrencies or tokens, limiting its flexibility.
