Smart Contract Deployment

Anyone can build a smart contract application on the Cybria Chain Mainnet or Testnet network. below is step by step walkthrough on how to deploy a simple smart contract counter using Remix.

Note: Before you start deploying using Remix, make sure you are connected Cybria Mainnet / Testnet in your metamask. See the Connect a Chain section for details.

What is Remix?

Remix is open-source Ethereum IDE you can use to write, compile and debug Solidity code. As such, Remix can be a hugely important tool in Web3 and dApps development/

you can jump to the Remix text editor Here (opens in a new tab) and copy paste this code below.

// SPDX-License-Identifier: MIT 
pragma solidity ^0.8.4;
contract TestCybriaSimpleCounter {
    int private count = 0;
    function incrementCounter() public {
        count += 1;
    function decrementCounter() public {
        count -= 1;
    function getCount() public view returns (int) {
        return count;

Compile Code

After the code is written, compile it using Solidity version based on the code written. Once the code is compiled, a green Check will be shown. it is ready to be deployed on the Cybria Blockchain. Click the Deploy button and a Metamask window will show pop up.

Smart Contract Ready

After the smartcontract is deployed, the contract address can be seen and you can interact. you can verify your contract on Explorer Cybria Testnet / Mainnet.
