BABYX [BabyXape] Token

BabyXape.swapBack() (#651-700) sends eth to arbitrary user
Dangerous calls:
- (tmpSuccess) = address(marketingWallet).call{gas: 30000,value: marketingShare}() (#682)
- (tmpSuccess1) = address(devWallet).call{gas: 30000,value: devShare}() (#683)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

DividendDistributor.distributeDividend(address) (#279-290) ignores return value by RewardToken.transfer(shareholder,amount) (#285)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Additional information: link

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

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

BabyXape.swapBack().tmpSuccess1 (#683) is written in both
(tmpSuccess1) = address(devWallet).call{gas: 30000,value: devShare}() (#683)
tmpSuccess1 = false (#687)
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.

DividendDistributor.shouldDistribute(address) (#274-277) uses timestamp for comparisons
Dangerous comparisons:
- shareholderClaims[shareholder] + minPeriod < block.timestamp && getUnpaidEarnings(shareholder) > minDistribution (#275-276)
Avoid relying on block.timestamp.

Pragma version^0.7.4 (#49) allows old versions
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.

Low level call in BabyXape.swapBack() (#651-700):
- (tmpSuccess) = address(marketingWallet).call{gas: 30000,value: marketingShare}() (#682)
- (tmpSuccess1) = address(devWallet).call{gas: 30000,value: devShare}() (#683)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
