receive function

[Naveed-Jameel]

in this video at 5:27:00 send eth 0.02>50$ from metamask to contract address. And apply a require statement to check if
price less than 50$ then revert error but i think before revert fund already added to contract wallet can anybody explain.

receive() external payble{
fund()
}

while require statement inside fund() function so revert will not effect to transfer eth/fund to contract address.

@Naveed-Jameel Not actually, Yes it is true that the gas cost will be deducted till the required statement for computation and if the statement gets failed then the remaining gas will be refunded back, but the value that we are sending will only be added to the contract when we pass the statement. As you can see we are storing msg.value to sender mapping after it.
