FUMA [FumaFinance] Token

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

FumaFinance.rescueERC20TokenFromContract() (FumaFinance.sol#631-634) ignores return value by ERC20Token.transfer(_owner,address(this).balance) (FumaFinance.sol#633)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Additional information: link

FumaFinance.ERC20Token (FumaFinance.sol#104) is never initialized. It is used in:
- FumaFinance.rescueERC20TokenFromContract() (FumaFinance.sol#631-634)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Contract ownership is not renounced (belongs to a wallet)

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.

Low level call in Address.sendValue(address,uint256) (Address.sol#6-11):
- (success) = recipient.call{value: amount}() (Address.sol#9)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
