Create new cryptocurrencies

In this topic, you will learn how to issue your own token on Ethereum platform using smart contracts. You need to follow below steps.

• Make sure that you are using Ropsten ETH on https://www.myetherwallet.com. Then Create a wallet on https://www.myetherwallet.com
• Transfer ether from special account with private key 6c73ee4c7d10d06463d58c7357fd0699727229ce4cee203b87e777e18e2980cc to your account. Otherwise you can mine ether on test network.
• Download the solidity script from https://github.com/bitfwdcommunity/Tutorials/blob/master/Tutorial%201/tutorial1_contract.sol
• Edit the solidity script by changing the token name and token class and constructor. See below for detailed instructions.
• Compile and Get object byte code from https://remix.ethereum.org/ for your token
• Sign and deploy contract on https://www.myetherwallet.com
• Register your contract on https://ropsten.etherscan.io/
• Done!!

How to edit the sample solidity script

You need to edit the solidity script as shown below.

• change contractName and Constructor name e.g. SagarToken
• change symbol name and name of new token
• Finally update the address at 2 locations (Enter your public ethereum address created in step 1)

 
contract SagarToken is ERC20Interface, Owned, SafeMath {
    // Constructor
    
    function SagarToken() public {
    symbol = “SAG“;
    name = “Sagar Token“;
    decimals = 18;
    _totalSupply = 100000000000000000000000000;
    balances[0x63B55BBe35E5bBAFC6A03f1175EC8fB2b9a1ed53] = _totalSupply;
    Transfer(address(0), 0x63B55BBe35E5bBAFC6A03f1175EC8fB2b9a1ed53, _totalSupply);
    }
    
    }
    

Compiling solidity script on https://remix.ethereum.org/Sign and Deploy the contract byte codeNow you can deploy new contract at https://www.myetherwallet.com/#contracts Register your contract on https://ropsten.etherscan.io/ Specify the correct contract name, select compiler name and select optimization as no. Then paste the source code of solidity script and then click on verify and publish.
