Setting Up the Development Environment

Instructions on setting up the necessary tools and environments for MetaChain development.

This comprehensive guide is designed to help you set up your development environment for building and deploying smart contracts on MetaChain. By the end of this guide, you'll have all the essential tools and configurations in place to kickstart your MetaChain development journey.

Operating System: This guide is tailored for Linux-based operating systems, but most steps are applicable to macOS and Windows as well

Version Compatibility: This guide is compatible with Node.js v14.

Prerequisites

• For Linux:

  • Computer with Linux OS: Ubuntu 20.04 or higher is recommended.

• For Mac:

  • Computer with macOS: macOS Catalina 10.15 or higher is recommended.

• For Windows:

  • Computer with Windows OS: Windows 10 or higher is recommended.

• Internet Connection: Required for downloading necessary software packages.

Step 1: Install Node.js and npm

Node.js is essential for running server-side JavaScript code, and npm is Node.js's package manager. Both are crucial for smart contract development.

# Update package list and install curl
sudo apt update
sudo apt install curl

# Install Node.js and npm
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt install -y nodejs

Step 2: Install Git

Git is a version control system that helps you manage your code.

# Install Git
sudo apt install git

---

Step 3: Install Text Editor

A text editor like Visual Studio Code is recommended for writing and editing your smart contracts.

# Install Visual Studio Code
sudo snap install code --classic

---

Step 4: Install Solidity Compiler

Solidity is the programming language used for writing smart contracts on MetaChain and other EVM compatible chains.

# Install Solidity
npm install -g solc

---

Step 5: Install Truffle

Truffle is a popular development framework for EVM chains like MetaChain that provides a suite of tools for smart contract development.

# Install Truffle globally
npm install -g truffle

Note: Hardhat is another excellent alternative to Truffle.

Step 6: Use Remix IDE (Optional)

Remix is an open-source web and desktop application that helps smart contract development, written in Solidity language for EVM blockchains.

• Remix IDE

---

Step 7: Install MetaMask Wallet Browser Extension

MetaMask is a wallet browser extension that allows you to interact with MetaChain and other EVM compatible blockchains.

• Install MetaMask for Chrome

---

Step 8: Set Up .env File for Storing Private Keys

Create a .env file in your project directory to securely store environment variables like your MetaMask private key.

# Create a .env file
touch .env

Security Warning: Never commit your .env file to public repositories. Always keep your private keys secure.

---

Step 9: Clone Example Project (Optional)

To get started quickly, you can clone an example MetaChain project.

# Clone example project
git clone https://github.com/exampleMetaChain/example-deployment.git

---

Congratulations, you've successfully set up your development environment for MetaChain smart contract development. You're now ready to start building and deploying smart contracts on MetaChain.
