AbsToken.claimBalance() (#435-437) sends eth to arbitrary user
Dangerous calls:
- address(fundAddress).transfer(address(this).balance) (#436)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

AbsToken.swapTokenForFund(uint256,uint256) (#335-367) ignores return value by FIST.transferFrom(address(_tokenDistributor),address(this),fistBalance - fundAmount) (#357)
AbsToken.claimToken(address,uint256,address) (#439-441) ignores return value by IERC20(token).transfer(to,amount) (#440)
AbsToken.processReward(uint256) (#472-517) ignores return value by FIST.transfer(shareHolder,amount) (#506)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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

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.

AbsToken._transfer(address,address,uint256) (#229-287) performs a multiplication on the result of a division:
-maxSellAmount = balance * 9999 / 10000 (#240)
-amount = maxSellAmount (#242)
-numTokensSellToFund = amount * swapFee / 5000 (#264)
Consider ordering multiplication before division.

AbsToken._tokenTransfer(address,address,uint256,bool,bool).feeAmount (#312) is a local variable never initialized
AbsToken._transfer(address,address,uint256).isSell (#247) is a local variable never initialized
AbsToken._transfer(address,address,uint256).takeFee (#246) 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 version^0.8.14 (#7) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.14 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.
