I currently have a BEP20 token which is owned by over 50 people (and hence why I dont want to mint another token). I'm looking to crowdsale it to more but I don't seem to find any tutorials of how to make a crowdsale contract for an already minted token.
Can anyone show me the way? I'm a beginner at solidiy and openzepplin but I am willing to learn. Thanks
Here's a simple crowdsale contract. It needs to hold the tokens (you need to send them to this contract address) before users are able to buy them.
pragma solidity ^0.8;
interface IERC20 {
function transfer(address to, uint256 amount) external returns (bool);
}
contract Crowdsale {
IERC20 public token;
uint256 price; // amount of tokens per 1 ETH
constructor (address _token, uint256 _price) {
token = IERC20(_token);
price = _price;
}
function buy() external payable {
uint256 amount = price * msg.value;
token.transfer(msg.sender, amount);
}
}
