$AASSX [AASSX] Token

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

AASSX.swapBack() (#616-665) sends eth to arbitrary user
Dangerous calls:
- (tmpSuccess) = address(marketingWallet).call{gas: 30000,value: marketingShare}() (#647)
- (tmpSuccess1) = address(devWallet).call{gas: 30000,value: devShare}() (#648)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Apply the check-effects-interactions pattern.

DividendDistributor.distributeDividend(address) (#239-250) ignores return value by RewardToken.transfer(shareholder,amount) (#245)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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.

Contract ownership is not renounced (belongs to a wallet)

AASSX.swapBack().tmpSuccess (#647) is written in both
(tmpSuccess) = address(marketingWallet).call{gas: 30000,value: marketingShare}() (#647)
tmpSuccess = false (#651)
AASSX.swapBack().tmpSuccess1 (#648) is written in both
(tmpSuccess1) = address(devWallet).call{gas: 30000,value: devShare}() (#648)
tmpSuccess1 = false (#652)
Fix or remove the writes.

Low level call in AASSX.swapBack() (#616-665):
- (tmpSuccess) = address(marketingWallet).call{gas: 30000,value: marketingShare}() (#647)
- (tmpSuccess1) = address(devWallet).call{gas: 30000,value: devShare}() (#648)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
