_You can follow along with the video course from here._ ### Introduction Let's begin by coding `FundMe`, a crowdfunding contract allowing users to send funds, which the owner can later withdraw. Before we start, let's clean up our Remix IDE workspace ### Setting up the project Start from scratch by opening your [Remix IDE](https://remix.ethereum.org/) and deleting all existing contracts. Next, create a new contract named `FundMe`. > 👀❗**IMPORTANT**:br > Before you start coding, try to write down in plain English what you want your code to achieve. This helps clarify your goals and structure your approach. We want `FundMe` to perform the following tasks: 1. **Allow users to send funds into the contract:** users should be able to deposit funds into the 'FundMe' contract 2. **Enable withdrawal of funds by the contract owner:** the account that owns `FundMe` should have the ability to withdraw all deposited funds 3. **Set a minimum funding value in USD:** there should be a minimum amount that can be deposited into the contract Let's outline the core structure of the contract: ```solidity // SPDX-License-Identifier: MIT pragma solidity ^0.8.18; contract FundMe {} ``` ### fund and withdraw functions The FundMe contract will have two primary functions that serve as the main interaction points: 1. **`fund`:** allows users to deposit funds into the contract 2. **`withdraw`:** grants the contract owner the ability to withdraw the funds that have been previously deposited First, let's code the `fund` function and leave the `withdraw` function commented out for the moment. ```solidity contract FundMe { // send funds into our contract function fund() public {} // owner can withdraw funds /*function withdraw() public {}*/ } ``` ### Conclusion In this lesson, we created a new `FundMe` contract and broadly defined the logic that will be performed. ### 🧑‍💻 Test yourself 1. 📕 Why should a developer always outline his coding goals before starting to code?
