Making your own cryptocurrency

Introduction

This is a small walkthrough on how to make your cryptocurrency using Solidity. We'll be using Remix IDE to wrote the code and you WILL need a Metamask account.

Set Up

The first step is to get some test ETH using your preferred testnet. I will be using the Mumbai Ploygon testnet.

So following along, go to your metamask plugin and cop your wallet address.

Polygon Faucet

A pop-up confriming that your transaction has succeeded will appear.

The next step is to start coding.

The code

Go to Remix IDE and o an create a new contract in the 'contracts' folder.

Then type in the followinf code

// SPDX-License-Identifier: MIT pragma solidity ^0.8.19; import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol"; contract MyToken is ERC20 { constructor(string memory _name, string memory _symbol) ERC20(_name, _symbol){ _mint(msg.sender, 10*10**18); } }

NOTE: The you might have to change the compiler version in the 'compiler' tab for the code to run. To do this, go to the Compiler tab and change the compiler version to '0.8.19+commit.7dd6d404' or any verison with 0.8.19. Please do note that selecting 0.8.20 or higher might not work.

FInally click CTRL+S or just hit the Compile myToken.sol button to compile the code.
