KaseiCoin-Crowdsale

This repository represents a fungible token that is ERC-20 compliant and that will be minted by using a Crowdsale contract from the OpenZeppelin Solidity library. The contract allows user manage the entire crowdsale process, allowing users to send ether to the contract and in return receive KaseiCoin tokens. Contract mints the tokens automatically and distributes them to buyers in one transaction.

Technologies

This project leverages the following tools for financial analysis:

• Solidity - programming language for implementing smart contracts.

• Remix IDE - Remix IDE allows developing, deploying and administering smart contracts for Ethereum like blockchains.

• TruffleSuite - Ganache - a personal Ethereum blockchain.

Solidity version:

pragma solidity ^0.5.0

OpenZeppelin libraries:

CrowdSale:

import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/release-v2.5.0/contracts/crowdsale/Crowdsale.sol";
import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/release-v2.5.0/contracts/crowdsale/emission/MintedCrowdsale.sol";

ERC20 token:

import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/release-v2.5.0/contracts/token/ERC20/ERC20.sol";
import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/release-v2.5.0/contracts/token/ERC20/ERC20Detailed.sol";
import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/release-v2.5.0/contracts/token/ERC20/ERC20Mintable.sol";

How to run

Step 1 - Install Ganache

Pls, download and install Ganache from https://trufflesuite.com/ganache/

Step 2 - Install and Configure the wallet Metamask

Pls, download and install wallet Metamask from https://metamask.io

Configure the Metamask:

• copy private account keys from Ganache and import them to create the Accounts

• configure network like on the screenshot

Step 3 - Open the smart contracts in the Remix IDE

Inject the testing account from the Ganache:

Confirm injection:

Step 4 - Compile and deploy Deployer contract

• compile smart contracts:

KaseiCoin:

KaseiCoinCrowdsale and KaseiCoinCrowdsaleDeployer:

Deploy Deployer

Pls, select and provide:

• deployer contract;

• NAME of Coin (Kasei);

• SYMBOL of Coin (KAS);

• WALLET (any valid address).

Click on Transact and confirm transaction in the Metamask

Check transaction in the Ganache:

Account balance:

Step 5 - Link the contract's addresses to the Remix

First use functions under CrowdSaleDeployer for taking contract's addresses:

CrowdSale contract

KaseiCoin contract

Second put addresses to At address field for linking contracts:

Finally contracts and their functions are got available for testing:

and

Step 6 - Interact with contracts

Try to buy tokens. Input value and address:

In my case Value is 5 Ethers.

Confirm with Metamask:

Check transaction in the Ganache:

and with function balanceOf check balance associated with testing account(s)

View the total supply of minted tokens:

View the amount of wei that has been raised in the crowdsale contract:
