Deploy your first Smart contract on Shardeum Testnet Blockchain

This guide will teach you how to create and deploy your first smart contract on the Shardeum blockchain.

What is Shardeum Blockchain :

• Shardeum is a EVM(Ethereum virtual machine) based layer-1 blockchain means you can build any dApp’s smart contract using solidity and vyper programming languages.
• low gas fees and high TPS ,when a new node joins the Shardeum network immediately increases the transactions per second (TPS).

prerequisites:

1. Metamask Wallet extension

Steps to write write your first smart contract

1. Go to the https://remix-project.org/ and open it
2. Create a new file “Attendence.sol” under “contract” folder

3. copy and paste this code in your “Attendence.sol” file

// SPDX-License-Identifier: GPL-3.0
pragma solidity >=0.7.0 <0.9.0;
contract Attendence {
address teacher = msg.sender;
uint  Totalstudent = 20;
uint public Totalstudent_pre  =0;
uint public todaystu;
mapping(address=>bool) public Present_in_class;
function yesMam(address studentID) public {
require(!Present_in_class[studentID],"already atended");
Present_in_class[studentID] = true;
Totalstudent_pre++;
}
function todayaatendence() public{
todaystu = Totalstudent - Totalstudent_pre;
}
}

Now compile your “Attendence.sol” file

Click Compile Attendance.sol and make sure there are no errors.
