Deploy a Token
A BHRC20 token contract keeps track of fungible tokens: any token is exactly equal to any other token; no tokens have special rights or behavior associated with them. This makes BHRC20 tokens useful for things like a medium of exchange currency, voting rights, staking, and more. As we know, both OpenZeppelin and ConsenSys maintain the standard library of BHRC contract classes. Simply put, BHRC20 is nothing more than a class with methods and members that run the logic of what we usually call cryptocurrency. However, it has a broader meaning because it also has applications in other use cases. Let's move on to learning how to create and deploy an BHRC20 token with the OpenZepplin library. Pre-requisites
Install Metamask
Configure Bahamut Mainnet on Metamask
Get mainnet token
Compile and Deploy BHRC20 Token. Open Remix IDE then create a new Token.sol contract and copy the below contract code to Token.sol.
// SPDX-License-Identifier: GPL-3.0
pragma solidity ^0.8.9;
import "@openzeppelin/contracts/token/BHRC20/BHRC20.sol";
contract BHRC20Token is ERC20 {
constructor(uint256 totalSupply) ERC20("DemoToken", "DET") {
// create totalSupply of tokens for the deployer
_mint(msg.sender, totalSupply);
}
}
Compile the contract
Switch to the compile page
Select proper compiler
Select BHRC20Token(Token.sol) contract
And then click Compile Token.sol
Deploy the contract
Click the button to switch to deploy button
Select Injected Provider-MetaMask
Select BHRC20Token-Token.sol
Fill in many tokens you want to mint and click Deploy button
Click Confirm button to sign and broadcast the transaction to chain.
Add custom token to MetaMask
Copy the deployed contract address
Click Import Tokens
Paste the contract address to the Token contract address
And the Token symbol and Token decimal will auto tilled by MetaMask
Finally, Click the Add custom token
Click the Import tokens button
When you reopen the MetaMask next time, you will see the token and amount.
