CatNIP is an NFT Project where players can play a game to mint collectible cat NFTs. The Cat NFTs are used in the game where you can use them to battle more cats in order to capture more cats and mint more NFTs. CatNIP has a game dev team, contract team, and art team. The currency, NIP, is used as an entry fee to play the game. NIP has a maximum total supply of 1 Billion, a 5% transaction tax, and no minting or burning function.

The purpose of the project is to allow players to use their minted NFTs in a game and have FUN!

CatNIP.RescueAmountBNBSentToContractAddress(uint256) (contracts/CatNIP.sol#992-994) sends eth to arbitrary user
Dangerous calls:
- PayableMsgSenderAddress().transfer(amount) (contracts/CatNIP.sol#993)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

CatNIP.excludedFromRewardAddresses (contracts/CatNIP.sol#84) is never initialized. It is used in:
- CatNIP.GetCurrentSupplyTotals() (contracts/CatNIP.sol#573-591)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

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.

CatNIP.GetReflectionTransferAmount(uint256) (contracts/CatNIP.sol#594-604) performs a multiplication on the result of a division:
-allTaxTokenAmount = transferAmount.mul(allTaxesPercent).div(100) (contracts/CatNIP.sol#597)
-reflectionAllTaxAmount = allTaxTokenAmount.mul(currentRate) (contracts/CatNIP.sol#600)
Consider ordering multiplication before division.

CatNIP.SwapAndLiquify(uint256) (contracts/CatNIP.sol#651-671) ignores return value by pancakeswapRouter.addLiquidityETH{value: newBalance}(address(this),half2,0,0,directorAccount,block.timestamp) (contracts/CatNIP.sol#669)
Ensure that all the return values of the function calls are used.

CatNIP.SetPairAddress(address).newPairAddress (contracts/CatNIP.sol#972) lacks a zero-check on :
- pancakeswapPair = newPairAddress (contracts/CatNIP.sol#973)

CatNIP.depositWallet (contracts/CatNIP.sol#173) is set pre-construction with a non-constant function or state variable:
- directorAccount
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

solc-0.8.6 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

- (success,returndata) = target.delegatecall(data) (contracts/libraries/Address.sol#167)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
