Hi Skyge,
I need ti implement this functionality in my Dapp using below contarct Mintable Tokens generation / crowdsale- mint single token/ perform crowdsale

pragma solidity ^0.6.2;

import “https://github.com/OpenZeppelin/openzeppelin-contracts/blob/v3.1.0/contracts/token/ERC20/ERC20.sol”;

contract Token is ERC20 {

constructor () public ERC20("Token", "TKN") {
    _mint(msg.sender, 1000000 * (10 ** uint256(decimals())));
}

}

So you mean you can mint only once?
