Hello, I follow your project for a while trying to understand the case and implicit assumptions, since there is not much documentation about the possible types of token funding sale events. There are a few training organizations but everyone solves an specific case and does not mention other possibilities.

In particular, I see that your case assumes both, a token and an icotoken, exists. This line in your icotoken requires an existing token https://github.com/jellydn/dapp-token-ico/blob/main/contracts/ITManTokenCrowdsale.sol#L19
also I think your project is designed to be run on mainnet.

However, in theory there is a previous case where the company wants to run a sale event but they do not have a token yet. This case of sale event would be run in a testnet (eg ropsten), funds would be send to the icotoken and after transferred to a wallet and balances will be added by default when the token is after created. I find this token sale case useful when the company has the idea but has not the resources to materialize the idea in a concrete token. I see a big risk creating a token expecting to last for years without change when you do not even have the company funded.

2 examples of the case I refer to:
https://github.com/ValladolidBlockchain/Token-ICO/blob/master/contracts/tokenVallCoin.sol
https://github.com/Vibes-INS/ico-hardhat/blob/master/contracts/Ico.sol
as you can see there is not token inside the icotoken and the only purpose is to transfer to the promoters wallet.

So, where do you thing this case of token sales with not token fit? Is this case covered in your work?

Thanks for sharing you work.

Hi sir

thanks for your job, if you increase the rate to more than 2500 wei in the script the buy button didnt work in the dapp. i tried with 4000 value.

Altough the contract could get directly BNB and make the exchange rate of token in the correct way.
