Dink Doink is a community Meme token forked from Australian Safe Shepherd ($ASS). Dink Doink is blurring the lines between entertainment and crypto. The token was fair launched, and every trade contributes toward automatically generating liquidity locked inside of PancakeSwap's liquidity pool. Holders are rewarded by earning passive rewards through static reflection!

DinkDoinkToken.addLiquidity(uint256,uint256) (#1096-1109) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1101-1108)
Ensure that all the return values of the function calls are used.

DinkDoinkToken._approve(address,address,uint256).owner (#1001) shadows:
- Ownable.owner() (#433-435) (function)
Rename the local variables that shadow another component.

- _maxTxAmount = _tTotal.mul(maxTxPercent).div(10 ** 2) (#906-908)
Emit an event for critical parameter changes.

Ownable.unlock() (#480-485) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#482)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#378-399) uses assembly
- INLINE ASM (#391-394)
Do not use evm assembly.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#246-249) is never used and should be removed
Remove unused functions.

Additional information: link

DinkDoinkToken._previousLiquidityFee (#728) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Additional information: link

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#378-399):
- (success,returndata) = target.call{value: weiValue}(data) (#382)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable DinkDoinkToken._maxTxAmount (#736) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#258)" inContext (#252-261)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable DinkDoinkToken.reflectionFromToken(uint256,bool).rTransferAmount (#845) is too similar to DinkDoinkToken._getTValues(uint256).tTransferAmount (#933)
Prevent variables from having similar names.

Additional information: link

DinkDoinkToken.slitherConstructorVariables() (#702-1161) uses literals with too many digits:
- numTokensSellToAddToLiquidity = 3000000000000 * 10 ** 1 * 10 ** 9 (#737)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

DinkDoinkToken.numTokensSellToAddToLiquidity (#737) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

isExcludedFromFee(address) should be declared external:
- DinkDoinkToken.isExcludedFromFee(address) (#997-999)
Use the external attribute for functions never called from the contract.
