Deploying Smart Contracts

Here I will guide you to deploy smart contracts with Remix IDE

Go to https://remix.ethereum.org/

Look at left side, you would see the folder structure

• Create new file with extension .sol in folder contract

• I will you some sample smart contract code for creating new Token in SWAN

// SPDX-License-Identifier: GPL-3.0
pragma solidity ^0.8.9;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/access/Ownable.sol";

contract DNHToken is ERC20, Ownable {

  constructor(uint256 initialSupply) ERC20("DNHToken", "DNH") Ownable(msg.sender) {
    _mint(msg.sender, initialSupply * (10**uint256(18)));
  }

  function mint(address to, uint256 amount) public onlyOwner {
    _mint(to, amount);
  }

}

• Copy all code above to your file you created then Ctrl + S to save

• After saving, IDE will compile your code then you will see

• Next, you click in the below button to deploy your compiled code

• Connect your Metamask, then Choose Injected Provider

• If you reach this step, you will see your address and your SWANETH Token

• Then you should choose like a image below, and fill 1B total supple

• Click Deploy and you have to sign with Metamask to deploy your contract. If you deploy your contract successfully, I will see in the log

• Note that, If you got error in deploy step. You can change your EVM server like image below. Then Deploy again

  
• If you reached here, congratulations! You Done. You just created a smart contract aka txn
