NAFTY, as a socialized re-distribution DeFi protocol, helps content creators to earn much more, and content consumers to pay much less via disintermediation, as well as receive rewards from all transactions across the Nafty Network, or in other words – whenever someone (i.e. consumers of adult content) make a transaction on any one of the platforms across the Nafty Network, whether someone is watching a video or communicating directly with a content creator, every token holder on the network receives part of the transaction to his or her wallet.

Nafty.swapETHForTokens(uint256) (#757-770) sends eth to arbitrary user
Dangerous calls:
- router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,deadAddress,block.timestamp.add(300)) (#764-769)
Nafty.addLiquidity(uint256,uint256) (#798-811) sends eth to arbitrary user
Dangerous calls:
- router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#803-810)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
