BME.addLiquidity(uint256,uint256) (BME Contract.sol#464-479) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,Lwallet,block.timestamp) (BME Contract.sol#470-477)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

BME.SWandSendBTCd(uint256,uint256) (BME Contract.sol#481-493) ignores return value by IERC20(BTC).transfer(address(dBTCTracker),swapedBTCtokens) (BME Contract.sol#487)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

ERC20._totalSupply (ERC20.sol#41) is never initialized. It is used in:
- ERC20.totalSupply() (ERC20.sol#95-97)

- ERC20._burn(address,uint256) (ERC20.sol#256-264)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

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.


Combination 2: Unchecked transfer + 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.

DividendPayingToken.accumulativeDividendOfBME(address)._owner (DividendPayingToken.sol#133) shadows:
- Ownable._owner (Ownable.sol#8) (state variable)
Rename the local variables that shadow another component.

DividendPayingToken.setBMEadd(address).newaddress (DividendPayingToken.sol#117) lacks a zero-check on :
- BME = address(newaddress) (DividendPayingToken.sol#118)
Check that the address is not zero.

Variable 'BME._transfer(address,address,uint256).claims (BME Contract.sol#382)' in BME._transfer(address,address,uint256) (BME Contract.sol#271-385) potentially used before declaration: ProcessedBTCDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (BME Contract.sol#383)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

BBTracking.processAccount(address,bool) (BME Contract.sol#694-713) uses timestamp for comparisons

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.

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (IUniswapV2Router.sol#12) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (IUniswapV2Router.sol#13)
Prevent variables from having similar names.

BBTracking.constructor() (BME Contract.sol#516-523) uses literals with too many digits:

Use: Ether suffix, Time suffix, or The scientific notation
