white paper

PIXL fuses the world of advertising with the metaverse. In true Web 3.0 fashion, it is a fresh way for advertisers to reach a new and engaged audience. Today, the crypto space is manipulated and flooded with a vast variety of different projects of which a large number are dishonest.

Through PIXL’s community and dedication to the values of transparency, honesty and integrity, this is a space for investors to interact with vetted and trusted projects, and for those projects to demonstrate and advertise their true value.

PixlCoin.swapTokens(uint256) (#664-681) sends eth to arbitrary user
Dangerous calls:
- _marketingWallet.transfer(marketingWalletETH) (#673)
- _operationsWallet.transfer(operationsWalletETH) (#674)
- _buybackWallet.transfer(transferredBalance.sub(marketingWalletETH).sub(operationsWalletETH)) (#675)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.

PixlCoin._takeLiquidity(uint256) (#804-815) performs a multiplication on the result of a division:
-_marketingWalletTokens = _marketingWalletTokens.add(rLiquidity.sub(rLiquidity.div(_liquidityFee).mul(_buybackFee)).sub(rLiquidity.div(_liquidityFee).mul(_operationsFee))) (#813)
Consider ordering multiplication before division.

PixlCoin._getRValues(uint256,uint256,uint256,uint256,uint256)._rValues (#779) 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.

PixlCoin._approve(address,address,uint256).owner (#627) shadows:
- Ownable.owner() (#159-161) (function)
Rename the local variables that shadow another component.

Ownable.unlock() (#194-199) uses timestamp for comparisons

Remove unused functions.

Additional information: link

PixlCoin._previousBurnFee (#455) is set pre-construction with a non-constant function or state variable:
- _burnFee
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) (#126-143):
- (success,returndata) = target.call{value: weiValue}(data) (#129)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable PixlCoin._buybackWallet (#459) is not in mixedCase
Follow the Solidity naming convention.
