DELOS DEFI aims to pair NFTs with real estate and agricultural projects with the intention of defining the rarity of NFTs based on the reward that each one will generate linked to the enterprises.

DELOS.addLiquidity(uint256,uint256) (#1506-1521) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (#1512-1519)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
