LordsOfDoge.swapBack() (#1643-1687) sends eth to arbitrary user
Dangerous calls:
- (success,None) = address(devWallet).call{value: ethForDev}() (#1671)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

LordsOfDoge._transfer(address,address,uint256) (#1470-1590) uses a dangerous strict equality:
- tradingActiveBlock == block.number && (automatedMarketMakerPairs[to] || automatedMarketMakerPairs[from]) (#1545)
Don't use strict equality to determine if an account has enough Ether or tokens.

Additional information: link


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.

Contract locking ether found:
Contract DividendTracker (#846-1110) has payable functions:
- DividendPayingToken.receive() (#718-720)
- DividendPayingToken.distributeDividends() (#736-738)
- DividendPayingTokenInterface.distributeDividends() (#259)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

LordsOfDoge.swapBack().success (#1670) is written in both
(success) = address(marketingWallet).call{value: ethForMarketing}() (#1670)
(success,None) = address(devWallet).call{value: ethForDev}() (#1671)
Fix or remove the writes.

DividendTracker.getAccount(address) (#963-1006) uses timestamp for comparisons
Dangerous comparisons:
- nextClaimTime > block.timestamp (#1003-1005)
DividendTracker.canAutoClaim(uint256) (#1027-1033) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#1028)
- block.timestamp.sub(lastClaimTime) >= claimWait (#1032)
Avoid relying on block.timestamp.

Pragma version0.8.11 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.11 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.
