Total Supply

1 ETH = 1000 Token [ you can change this ratio by making chances in migrations/2_deploy_contracts.js file ]

Requirement:

• Nodejs v9.10 or above
• Truffle v4.1.8 (core: 4.1.8) (http://truffleframework.com/docs/getting_started/installation)
• Solidity v0.4.23
• Metamask (https://metamask.io) /Ganache Wallet

[Please Note : infura.io provider is used for the demo ]

Deployment Steps:

git clone https://github.com/imperialsoftech/okt-token
cd okt-token/
npm install

Update the migrations/2_deploy.contracts.js file

const IcoToken = artifacts.require('IcoToken');
const IcoContract = artifacts.require('IcoContract');

module.exports = function(deployer){
	deployer.deploy(
			IcoToken,
			'OK Token',
			'OKT',
			'18',
			'1.0'
		).then(() => {
			return deployer.deploy(
					IcoContract,
					'0xab0874cB6........', // put your Rinkeby wallet address here, for link your account to token contract
					IcoToken.address,
					'100000000000000000000000000', // 100000000 Token
				    '1000', // 1 ETH = 1000 Token
				    '1514764800', // 01/01/2018
				    '1546214400', // 31/12/2018
				    '100000000000000000' // 0.1 ETH
				).then(() => {
					return IcoToken.deployed().then(function(instance){
						return instance.setIcoContract(IcoContract.address);	
					});
				});
		});
};

Create an account at infura.io and update your key with API_KEY_HERE

Update the truffle.js file

var HDWalletProvider = require("truffle-hdwallet-provider");
module.exports = 
{
    networks: 
    {
	    rinkeby: {
		    provider: function() {
		      var mnemonic = 'steel neither flight ...'; //put ETH wallet 12 mnemonic code	
		      return new HDWalletProvider(mnemonic, "https://rinkeby.infura.io/<API_KEY_HERE>"); // 
		    },
		    network_id: '4',
		}  
    }
};

Also update your ethereum address and end date timestamp in migrations/2_deploy_contracts.js file

Go to your project folder in terminal then execute :

truffle compile 
truffle migrate --network rinkeby

Send 1 ETH to ICOContract address from your rinkeby wallet
