How to write a token sale that supports usdc and eth as acceptable payment method

Question

I've built a token sale contract for my new token but i can't figure out how to implement usdc as an acceptable exchange coin for my token

Answer 1

Could do something like this:

    function sale(bool isUSDC, uint amount) external {
    if(isUSDC) {
    IERC20(USDCaddress).safeTransferFrom(msg.sender, address(this), amount);
    uint tokenAmount = calculatePricePerUSD(amount);
    IERC20(token).safeTransfer(msg.sender, tokenAmount);

} else {

    require(msg.value == amount, "Received funds not sufficient");

    uint tokenAmount = calculatePricePerETH(amount);
    IERC20(token).safeTransfer(msg.sender, tokenAmount);

}

}
