Smart Contract

Folder Structure

Let’s view the file structure for a default foundry project:

$ cd hello_foundry
$ tree . -d -L 1
.
├── lib
├── script
├── src
└── test

4 directories

Demo smart contract

In the src folder, you will find a simple smart contract called counter.sol. Which contains a simple counter contract.

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.13;

contract Counter {
uint256 public number;

function setNumber(uint256 newNumber) public {
number = newNumber;
}

function increment() public {
number++;
}
}

Compile the Contract

To build the contract, run the following command in the project's root directory.

forge build

This will compile your smart contracts and generate out directory:

forge build

[] Compiling 36 files with Solc 0.8.24
