Reentrancy in SafuDev.transferFrom(address,address,uint256) (#230-236):
External calls:
- _transfer(sender,recipient,amount) (#233)
- _uniswapV2Router.addLiquidityETH{value: amount}(address(this),tokenAmount,0,0,address(this),block.timestamp + 1200) (#188)
- _uniswapV2Router.swapExactTokensForETHSupportingFeeOnTransferTokens(amount,0,path,address(this),block.timestamp + 1200) (#196)
External calls sending eth:
- _transfer(sender,recipient,amount) (#233)
- _uniswapV2Router.addLiquidityETH{value: amount}(address(this),tokenAmount,0,0,address(this),block.timestamp + 1200) (#188)
State variables written after the call(s):
- _approve(sender,msg.sender,currentAllowance - amount) (#234)
- _allowances[owner][spender] = amount (#221)
Apply the check-effects-interactions pattern.

SafuDev.withdrawToken(address,uint256) (#276-279) ignores return value by _tokenContract.transfer(msg.sender,amount) (#278)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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


Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

SafuDev._transfer(address,address,uint256) (#149-184) performs a multiplication on the result of a division:
-liquidityAmount = amount / 100 * liquidityFee (#170)
Consider ordering multiplication before division.

SafuDev.addLiquidity(uint256,uint256) (#186-189) ignores return value by _uniswapV2Router.addLiquidityETH{value: amount}(address(this),tokenAmount,0,0,address(this),block.timestamp + 1200) (#188)
Ensure that all the return values of the function calls are used.

SafuDev.setFees(uint8,uint8) (#104-107) should emit an event for:
- devFee = _devFee (#105)
- liquidityFee = _liquidityFee (#106)
Emit an event for critical parameter changes.

SafuDev.setAddresses(address)._devWallet (#94) lacks a zero-check on :
- devWallet = _devWallet (#95)
Check that the address is not zero.
