FundMe Project

Overview

The FundMe project is a decentralized funding contract built on the Ethereum blockchain. It allows users to fund the contract with ETH and enables the owner to withdraw the funds. The project utilizes Chainlink's price feeds to ensure that the funding amounts meet a minimum threshold in USD.

Features

• Users can fund the contract with ETH.
• The contract checks the current ETH/USD price using Chainlink oracles.
• Only the contract owner can withdraw the funds.
• Supports multiple funders and keeps track of their contributions.

Technologies Used

• Solidity
• Ethereum
• Chainlink
• Forge (for testing and deployment)

Installation

To get started with the FundMe project, follow these steps:

1. Clone the repository:

   git clone https://github.com/cgrade/fundme.git
   cd fundme

2. Install dependencies: Make sure you have Foundry installed. If not, you can install it using:

   curl -L https://foundry.paradigm.xyz | bash
   foundryup

3. Install required libraries:

   forge install

Usage

Deployment

To deploy the FundMe contract, run the following command:

forge script script/DeployFundMe.s.sol --broadcast

This will deploy the FundMe contract to the active network specified in the HelperConfig script.

Testing

To run the tests for the FundMe contract, use the following command:

forge test

This will execute all the tests defined in the test/FundMeTest.t.sol file.

Contract Structure

• script/DeployFundMe.s.sol: Script for deploying the FundMe contract.
• src/FundMe.sol: Main contract that handles funding and withdrawals.
• script/HelperConfig.s.sol: Provides network-specific configurations for deployment.
• test/FundMeTest.t.sol: Contains tests for the FundMe contract.
• test/mocks/MockV3Aggregator.t.sol: Mock contract for testing price feeds.
