BUSDX Token

BUSDX.swapETHForTokens(uint256) (BUSDX.sol#424-439) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,deadWallet,block.timestamp) (BUSDX.sol#431-436)
BUSDX.addLiquidity(uint256,uint256) (BUSDX.sol#482-497) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (BUSDX.sol#488-495)
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.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract ownership is not renounced (belongs to a wallet)

BUSDX._transfer(address,address,uint256).iterations (BUSDX.sol#377) is a local variable never initialized
BUSDX._transfer(address,address,uint256).claims (BUSDX.sol#377) is a local variable never initialized
BUSDX._transfer(address,address,uint256).lastProcessedIndex (BUSDX.sol#377) 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.
