PCKT [Pocket] Token
About PCKT

Website
Pocket Doge is a multi-reflection token where investors can choose between a number of approved tokens to receive as rewards. Future partnerships with other tokens, who meet our stringent criteria, will allow the community to vote on other projects they would like added to the list of reflection options.
A blockchain-based game is also being developed, along with an NFT marketplace. Pocket Doge is the first token of the wider Pocket Pets Ecosystem, which will have additional tokens, with specific use-cases, developed in the future.

PCKT.swapBack() (#2317-2352) sends eth to arbitrary user
Dangerous calls:
- (success,None) = address(devWallet).call{value: bnbForDev}() (#2343)
- (success,None) = address(dividendTracker).call{value: bnbForRewards}() (#2344)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Reentrancy in PCKT.buyBackTokensWithNoFees() (#2121-2149):
External calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: ethAmount}(0,path,address(msg.sender),block.timestamp + 360) (#2139-2144)
State variables written after the call(s):
- _isExcludedFromFees[msg.sender] = prevExclusion (#2146)
Apply the check-effects-interactions pattern.

PCKT.swapBack().success (#2342) is written in both
(success,None) = address(devWallet).call{value: bnbForDev}() (#2343)
(success,None) = address(dividendTracker).call{value: bnbForRewards}() (#2344)
Fix or remove the writes.

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.
Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.
PCKT._transfer(address,address,uint256) (#2179-2315) performs a multiplication on the result of a division:
-fees = amount.mul(sellTotalFees).div(100) (#2281)
-tokensForP2E = fees * sellP2eFee / sellTotalFees (#2286)
Consider ordering multiplication before division.

PCKT._transfer(address,address,uint256) (#2179-2315) uses tx.origin for authorization: require(bool,string)(_holderLastTransferTimestamp[tx.origin] < block.number,_transfer:: Transfer Delay enabled. Only one purchase per block allowed.) (#2213)
Do not use tx.origin for authorization.
Additional information: link
PCKT._transfer(address,address,uint256).iterations (#2309) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

PCKT.addLiquidity(uint256,uint256) (#2375-2390) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (#2381-2388)
Ensure that all the return values of the function calls are used.

PCKT.constructor().totalSupply (#1734) shadows:
- ERC20.totalSupply() (#507-509) (function)
- IERC20.totalSupply() (#74) (function)
Rename the local variables that shadow another component.

PCKT.updateMaxAmount(uint256) (#1938-1941) should emit an event for:
- maxTransactionAmount = newNum * (10 ** 18) (#1940)
Emit an event for critical parameter changes.
Additional information: link
PCKT.updateP2EWallet(address).newWallet (#1896) lacks a zero-check on :
- p2eWallet = newWallet (#1897)
Check that the address is not zero.

PCKT.airdropToWallets(address[],uint256[]) (#1865-1873) has external calls inside a loop: dividendTracker.setBalance(address(wallet),balanceOf(wallet)) (#1871)
Favor pull over push strategy for external calls.

Variable 'PCKT._transfer(address,address,uint256).claims (#2309)' in PCKT._transfer(address,address,uint256) (#2179-2315) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#2310)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

DividendTracker.canAutoClaim(uint256) (#1506-1512) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#1507)
- block.timestamp.sub(lastClaimTime) >= claimWait (#1511)
Avoid relying on block.timestamp.

- (success,None) = address(dividendTracker).call{value: bnbForRewards}() (#2344)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
