This is demonstrations of simple smart contract written on Solidity programming language. This code is written while following the free course on Solidity by Patrick Collions.

This project is developed with hardhat framework using TypeScript. This project demonstrates an advanced Hardhat use case, integrating other tools commonly used alongside Hardhat in the ecosystem.

All the smart contracts are written inside /contracts folder. The FundMe smart contract allow the contract owner to collect fund from different funders. It also allow to withdraw fund by the owner or deployer.

I have used chainlink to get the ETH price so that funders sent at least minimum amount of ETH.

All the test code is in /test folder. Deploy scripts are inside the /deploy folder.

We have tested the code in localhost and hardhat local network. For testnet we have used rinkeby. Make sure you have some ETH in your testnet network. You can get free testnet ETH on major testnet network by chainlink website.

To run and test the code in your local development machine copy the repo with following command. We have used yarn package manager. You can use NPM.

git clone https://github.com/sanjaydefidev/hardhat-fund-me

Installing all the dependencies

yarn install

To comile the solidity.

yarn hardhat compile

To deploy on testnet.

yarn hardhat deploy --network rinkeby

To run the mocha tests.

yarn hardhat test
