Using Remix
Deploys a ERC20 smart contract with a message, and renders it in the front-end. You can interact with the smart contract easily!
This dApp implements a "Hello World" style application that echoes a message passed to the contract to the front end. This tutorial is intended to be followed using the online IDE available at Remix IDE.
Setting Up Remix IDE
Remix is an online IDE to develop smart contracts.
You need to choose Solidity Compiler and Deploy and Run Transactions.
Go to File Explorers, And Create a new file, Name it ERC20Token.sol
Copy/Paste the Smart contract below into the newly created file
ERC20Token.sol
Writing the Smart Contract
Create a new contract ERC20Token.sol and copy the contract code from the ERC20 token template here
Modify "TOKEN_NAME", "TOKEN_SYMBOL", "DECIMALS" and "TOTAL_SUPPLY" according to your requirements.
In the first line, pragma solidity ^0.8.0 specifies that the source code is for a Solidity version greater than 0.8.0. Pragmas are common instructions for compilers about how to treat the source code (e.g., pragma once).
A contract in the sense of Solidity is a collection of code (its functions) and data (its state) that resides at a specific address on the Ethereum blockchain. Learn more about the constructor and memory in the docs.
Compile Smart Contract
Step1: Click the button to switch to compile page
Step2: Select the "ERC20Token" contract
Step3: Enable "Auto compile" and "optimization"
Step4: Click "ABI" to copy contract ABI and save it.
Deploy Smart Contract Using TestNet
Now, We have to deploy our smart contract on BizNet Network. For that, we have to connect to web3 world, We will be using Metamask.
Copy your address from Metamask
Head over to Faucet - https://faucet.bosagora.org/request/boa/your-address and request test BOA
Now, let's Deploy the Smart Contract on Testnet
Select "Injected Web3" in the ENVIRONMENT dropdown and your contract
Metamask accepts the Connection Request!
From the CONTRACT dropdown menu, select the ERC20Token.sol you created earlier.
Click the Deploy button in Remix and accept another Metamask popup that requires transaction confirmation once connected!
Congratulations! You have successfully deployed an ERC20 Contract. Now you can interact with the Smart Contract. Check the deployment status here: https://testnet-scan.bosagora.org
