DGM [Degem] Token

DegemV2.LiquidityRelease() (#331-343) ignores return value by liquidityToken.transfer(msg.sender,amount) (#341)
DegemV2.withdrawToken(address,uint256) (#413-416) ignores return value by tokenContract.transfer(msg.sender,_amount) (#415)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

DegemV2._swapContractToken(bool) (#232-256) sends eth to arbitrary user
Dangerous calls:
- (sent) = paymentSplitter.call{value: address(this).balance}() (#254)

Too many vulnerabilities (Unchecked transfer, Reentrancy vulnerability, etc.). High risk of a scam. DYOR & manual audit are advised.

Contract ownership is not renounced (belongs to a wallet)

DegemV2._swapContractToken(bool).sent (#254) is written in both
(sent) = paymentSplitter.call{value: address(this).balance}() (#254)
sent = true (#255)
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.

Combination 2: Unchecked transfer + 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.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Low level call in DegemV2._swapContractToken(bool) (#232-256):
- (sent) = paymentSplitter.call{value: address(this).balance}() (#254)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

DegemV2._circulatingSupply (#85) should be constant
Add the constant attributes to state variables that never change.

DegemV2._swapContractToken(bool) (#232-256) performs a multiplication on the result of a division:
-tokenToSwap = _balances[_pancakePairAddress] * swapTreshold / 1000 (#235)
-tokenForLiquidity = (tokenToSwap * liquidityTax) / totalTax (#241)
DegemV2._swapContractToken(bool) (#232-256) performs a multiplication on the result of a division:
-LiqHalf = tokenForLiquidity / 2 (#245)
-liqBNB = (newBNB * LiqHalf) / swapToken (#251)
Consider ordering multiplication before division.

DegemV2.protector_function(address[],bool).i (#131) is a local variable never initialized
DegemV2.manage_blacklist(address[],bool).i (#126) 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.

Pragma version0.8.10 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.10 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.

Contract has 7% buy tax and 7% sell tax.
Taxes are low but contract ownership is not renounced. Token has a high risk of becoming a honeypot.

Average 30d PancakeSwap volume is low.

Average 30d number of PancakeSwap swaps is low.
