ApyFreedom Token

ApyFreedom.swapETHForTokens(uint256) (#821-836) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,deadAddress,block.timestamp.add(300)) (#828-833)
ApyFreedom.addLiquidity(uint256,uint256) (#838-851) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#843-850)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

ApyFreedom._transfer(address,address,uint256) (#664-781) uses a weak PRNG: "_bBSLimit = _bBSLimitMin + uint256(keccak256(bytes)(abi.encodePacked(block.timestamp,block.difficulty))) % (_bBSLimitMax - _bBSLimitMin + 1) (#725)"
Do not use block.timestamp, now or blockhash as a source of randomness

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

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 ownership is not renounced (belongs to a wallet)

ApyFreedom._rTotal (#425) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
ApyFreedom._previousTaxFee (#448) is set pre-construction with a non-constant function or state variable:
- _taxFee
ApyFreedom._previousLiquidityFee (#451) 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.
