so the first thing that we want to do is let's once again delete everything in our remix so we can start from scratch so I have the contracts that we're actually going to be building in here you might have the simple storage the ad5 extra the storage Factory Etc let's

go ahead right click and just delete everything we're going to start completely from blank here so let's go ahead and delete everything in here all right great so let's go ahead and start creating our contract we're going to call it fund me.sol one thing that's

really good when you actually start building any code at all is to first write down what you want it to do so what do we want ours to do we want to get funds from users into this contract withdraw funds to the owner of the contract or whoever has created this

fund me contract and then we also want to set a minimum funding value in USD we don't want people to be able to donate just a penny so let's go ahead and set this up SPDX license identifier identifier MIT do pragma solidity carrots 0.8.18 contract fund me let's go ahead

and delete these comments so before we embark on writing all of our functionality out let's just write down the functions that we want to build so we're probably going to want a function fund which is going to be the function they call to send money to our contract

we're going to want a function withdraw which is going to be the function that the owner of the contract is going to use to withdraw the money that the funders send us and those are going to be the two main functions that our contract is going to need we're going to

be implementing more functions than just this but these are going to be the main functions to interact with our protocol or interact with our fund me contract let's comment out withdraw for now and just start focusing on fund

새로 시작하려면 리믹스 IDE에서 기존 계약을 삭제하세요.

'fundme.sol'이라는 새 컨트랙트를 생성합니다.

계약의 목적을 정의합니다: 자금 수령, 소유자의 출금 허용, 최소 펀딩 금액 설정.

SPDX 라이선스 식별자 및 Solidity 버전을 포함하세요.

계약에 송금하는 '자금' 기능에 대해 간략하게 설명합니다.

소유자가 자금을 인출할 수 있는 '인출' 기능에 대해 설명합니다.

처음에는 '펀드' 기능을 구현하는 데 집중하세요.
