I have a question so if we want to have an auction system in the marketplace should we have another contract for Auction or should we put it inside the marketplace contract.
And second, is there any point to make a bit in the smart contract other than the balance check or if we do it on the website is it have any disadvantage because right now we have argued about this one in our project. Because the fee is quite high if we have bid on the smart contract which might not pleasant.
