LOUD Market is the Music NFT Marketplace! Loud is token built to support Loud Market’s NFT Marketplace. This platform has been created to empower musicians and artists in selling their work as NFTs instantly, at fair prices with no hidden fees! Their platform gives artists the opportunity to promote their media and create another source of income in the form of instant cryptocurrency payments. NFTs can be listed at a single sale price or sold through auction. Additionally, artists can include a “Royalty fee” guaranteeing them a percentage of all the future sales. $LOUD tokens will be accepted as payment by the content creators, musicians and artists.

Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

LoudMarket.swapETHForTokens(uint256) (LoudMarket.sol#425-440) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,deadWallet,block.timestamp) (LoudMarket.sol#432-437)
LoudMarket.addLiquidity(uint256,uint256) (LoudMarket.sol#483-498) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (LoudMarket.sol#489-496)
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.
