white paper

DOGEPEPSI project has been conceived and developed by a group of highly motivated people driven by a strong passion and knowledge of the crypto world.

As part of the staff is American, the project intends to merge the significant meaning of “Pepsi”, as a drink and global icon for people of all ages, and that of “Doge”, as a symbol of top-level token.

Our aim is to achieve unprecedented and extraordinary results that no token has ever been able to achieve, come on board and be part of the journey with us!
Nowadays, plastic crisis is one of the greatest challenges that we all have to face in order to preserve our Planet Earth. Currently, 12.7 million tonnes of plastic ends up in our oceans each year, causing serious consequences for sealife and, indirectly, for all of us.

It is absolutely mandatory to face this terrible issue all together, as a community. To do so, we have to act quickly and involve relevant actors at different levels.

DogePepsi.addLiquidity(uint256,uint256) (#840-853) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#845-852)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Additional information: link

DogePepsi._transfer(address,address,uint256) (#666-783) uses a weak PRNG: "_bBSLimit = _bBSLimitMin + uint256(keccak256(bytes)(abi.encodePacked(block.timestamp,block.difficulty))) % (_bBSLimitMax - _bBSLimitMin + 1) (#727)"
Do not use block.timestamp, now or blockhash as a source of randomness

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.

DogePepsi._transfer(address,address,uint256).sellHistory (#682) 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.

Additional information: link

DogePepsi.addLiquidity(uint256,uint256) (#840-853) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#845-852)
Ensure that all the return values of the function calls are used.

DogePepsi._approve(address,address,uint256).owner (#658) shadows:
- Ownable.owner() (#157-159) (function)
Rename the local variables that shadow another component.

DogePepsi.setNumTokensSellToAddToBuyBack(uint256) (#1098-1100) should emit an event for:
- minimumTokensBeforeSwap = _minimumTokensBeforeSwap (#1099)
Emit an event for critical parameter changes.

DogePepsi.setMarketingAddress(address)._marketingAddress (#1102) lacks a zero-check on :
- marketingAddress = address(_marketingAddress) (#1103)
Check that the address is not zero.

DogePepsi._removeOldSellHistories() (#1015-1037) uses timestamp for comparisons
Dangerous comparisons:
- _sellHistories[j].time >= maxStartTimeForHistories (#1021)
Avoid relying on block.timestamp.

Remove unused functions.

Additional information: link

DogePepsi._previousLiquidityFee (#453) 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

solc-0.8.4 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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#124-141):
- (success,returndata) = target.call{value: weiValue}(data) (#127)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable DogePepsi._isEnabledBuyBackAndBurn (#489) is not in mixedCase

Variable DogePepsi.reflectionFromToken(uint256,bool).rTransferAmount (#624) is too similar to DogePepsi._getValues(uint256).tTransferAmount (#919)
Prevent variables from having similar names.

DogePepsi.slitherConstructorVariables() (#410-1188) uses literals with too many digits:
- minimumTokensBeforeSwap = 200000 * 10 ** 6 * 10 ** 9 (#472)
Use: Ether suffix, Time suffix, or The scientific notation
