I'm paying 0.38 gas fees in this function. There's something wrong with it?
function claim() external {
require(allowed[msg.sender] === true, 'This address is not allowed to perform withdrawns');
require(BUSD.balanceOf(address(this)) > block.timestamp - moment[msg.sender] * allowance[msg.sender], 'Not enough balance');
uint amount = moment[msg.sender] * allowance[msg.sender];
BUSD.transferFrom(address(this), msg.sender, amount);
allowance[msg.sender] = 0;
emit claimed(msg.sender, amount);
}
