Gittu – ICO/IDO/IGO Token Presale Template With Smart Contract (React JS+Solidity)

Introduction

Welcome to this tutorial on using the Gittu ICO/IDO/IGO Token Presale Template with Smart Contract (React JS + Solidity). This comprehensive guide will walk you through the process of deploying a token presale template using Gittu's template, which is specifically designed for Initial Coin Offerings (ICOs), Initial Decentralized Offerings (IDOs), and Initial Game Offerings (IGOs).

Gittu's template provides a robust and customizable framework for creating a token presale platform, complete with smart contract functionality. In this tutorial, we'll explore how to set up the template, deploy it to the Ethereum blockchain, and integrate it with a React JS frontend.

By the end of this tutorial, you'll have a comprehensive understanding of how to use the Gittu ICO/IDO/IGO Token Presale Template with Smart Contract, and you'll be able to deploy your own token presale platform.

Prerequisites

Before we begin, please make sure you have the following:

1. Basic knowledge of Solidity (the programming language used for writing smart contracts)
2. Familiarity with React JS (the frontend framework used for building the template)
3. A local Ethereum development environment set up (e.g., using MetaMask and Truffle)
4. A computer with a stable internet connection

Step 1: Setting up the Template

To start, download the Gittu ICO/IDO/IGO Token Presale Template from the Gittu website.

Unzip the template folder and navigate to the templates directory. Inside, you'll find three folders: ico, ido, and igo. Each folder contains a separate template for each type of token presale.

For this tutorial, we'll use the ico template. Feel free to explore the other templates and modify them as needed for your specific use case.

Step 2: Deploying the Smart Contract

To deploy the smart contract, you'll need to compile and deploy the contract to the Ethereum blockchain using Truffle. Here's how:

1. Open the templates/ico folder in your terminal.
2. Run the command truffle compile to compile the smart contract.
3. Run the command truffle migrate to deploy the smart contract to the Ethereum blockchain.

Note: Make sure you have your Ethereum development environment set up and configured before attempting to deploy the smart contract.

Step 3: Setting up the React JS Frontend

Now that the smart contract is deployed, it's time to set up the React JS frontend. Here's how:

1. Create a new React JS project using create-react-app.
2. Install the web3 and ethers packages using npm or yarn: npm install web3 ethers or yarn add web3 ethers.
3. Import the web3 and ethers libraries in your React JS components and use them to interact with the smart contract.
4. Configure the frontend to connect to the smart contract using the contract address and ABI (Application Binary Interface).

Here's some sample code to get you started:

import React, { useState, useEffect } from 'react';
import Web3 from 'web3';
import { ethers } from 'ethers';

const contractAddress = '0x...'; // replace with your contract address
const contractABI = [...]; // replace with your contract ABI

function TokenPresale() {
  const [balance, setBalance] = useState(0);
  const [presaleAmount, setPresaleAmount] = useState(0);

  useEffect(() => {
    const web3 = new Web3(window.ethereum);
    const contract = new ethers.Contract(contractAddress, contractABI, web3);

    contract.getBalance().then((balance) => {
      setBalance(balance);
    });

    contract.getPresaleAmount().then((presaleAmount) => {
      setPresaleAmount(presaleAmount);
    });
  }, []);

  return (
    <div>
      <h1>Token Presale</h1>
      <p>Balance: {balance}</p>
      <p>Presale Amount: {presaleAmount}</p>
      <button onClick={() => {
        // send eth to contract
        //...
      }}>Buy Token</button>
    </div>
  );
}

export default TokenPresale;

Step 4: Connecting to the Smart Contract

In this step, you'll connect to the smart contract using the ethers library and update the frontend to reflect the latest contract state.

Here's some sample code to get you started:

import React, { useState, useEffect } from 'react';
import Web3 from 'web3';
import { ethers } from 'ethers';

const contractAddress = '0x...'; // replace with your contract address
const contractABI = [...]; // replace with your contract ABI

function TokenPresale() {
  const [balance, setBalance] = useState(0);
  const [presaleAmount, setPresaleAmount] = useState(0);

  useEffect(() => {
    const web3 = new Web3(window.ethereum);
    const contract = new ethers.Contract(contractAddress, contractABI, web3);

    contract.on('BalanceUpdated', (newBalance) => {
      setBalance(newBalance);
    });

    contract.on('PresaleAmountUpdated', (newPresaleAmount) => {
      setPresaleAmount(newPresaleAmount);
    });
  }, []);

  return (
    <div>
      <h1>Token Presale</h1>
      <p>Balance: {balance}</p>
      <p>Presale Amount: {presaleAmount}</p>
      <button onClick={() => {
        // send eth to contract
        //...
      }}>Buy Token</button>
    </div>
  );
}

export default TokenPresale;
