Cloudy ICO Smart Contract

This repository contains a Solidity smart contract for the Cloudy ICO, as well as the associated Cloudy token contract. The Cloudy ICO smart contract allows users to participate in a token sale event. It is built using Solidity, OpenZeppelin libraries, Chainlink price feeds, and custom libraries.

Contract Overview

The Cloudy ICO contract facilitates the sale of tokens during a presale event. It interacts with the Cloudy token contract and allows users to purchase tokens using various ERC-20 tokens. The presale contract ensures that tokens are sold at a fixed price in USD and enforces certain rules to maintain the integrity of the sale.

Features

• Purchase tokens using supported ERC-20 tokens before the presale is unlocked.
• Withdraw purchased tokens after the presale is unlocked.
• Burn remaining unsold tokens after the presale is unlocked.
• Withdraw all remaining tokens, including those of supported ERC-20 tokens.
• View contract and token information through various public and external functions.

Technologies Used

• Solidity: A programming language for writing smart contracts on the Ethereum platform.
• Foundry: A development framework for building decentralized applications.
• OpenZeppelin Contracts: A library of reusable smart contracts for Ethereum.
• Chainlink Price Feeds: Used for obtaining accurate token prices in USD.

Contract Addresses

• Cloudy ICO Contract: 0x5536B2802712ebFC248A895b31719A7b5e97378d
• Cloudy Token Contract: 0xDe72C023C9a56a1794Ef27adC213f09bD64BcE58

Usage

• Deploy the Cloudy ICO and Cloudy token contracts to your Ethereum network.
• Configure the presale parameters, including unlock timestamp, token price, maximum supply, and allowed tokens during contract deployment.
• Users can participate in the presale by calling the buy function with supported ERC-20 tokens.
• After the presale is unlocked, users can withdraw their purchased tokens using the withdraw function.
• Any remaining unsold tokens can be burned by calling the burnRemaining function.
• The owner can withdraw any ERC20 tokens used with the withdrawAllTokens function.
• View contract and token information using various public functions.

Testing

To test the Cloudy ICO smart contract, you can use the Foundry framework. Below are the steps to run tests:

1. Install Foundry if you haven't already: Foundry Documentation

2. Clone this repository to your local environment.

3. Navigate to the project directory in your terminal.

4. Run the following command to execute the tests in a local environment:

   forge test
