Hard Money Lenders For Wholesaling

Ok, So i am looking to make my first deal happen soon, hopefully within the next couple of months. I want to wholesale a few houses and then get into multi family units. So my question is about funding. If I were to get approval from a hard money lender, receive the proof of funds letter to get the contract in my name, and then assign the contract prior to actually receiving the money, is that wrong, illegal, or in some way unethical? And if so how? Thanks in advance!
