MNet [MetaNet] Token

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

Contract creator or owner is blacklisted for past scams

MetaNet.swapAndLiquify(uint256) (#823-838) sends eth to arbitrary user
Dangerous calls:
- marketingWallet.transfer(newBalance.div(allFee).mul(_marketingFee)) (#837)
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.

Low level call in Address.sendValue(address,uint256) (#91-95):
- (success) = recipient.call{value: amount}() (#93)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#118-135):
- (success,returndata) = target.call{value: weiValue}(data) (#121)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

MetaNet.setmarketingWallet(address).newWallet (#964) lacks a zero-check on :
- marketingWallet = address(newWallet) (#966)
Check that the address is not zero.

MetaNet.slitherConstructorVariables() (#429-1056) uses literals with too many digits:
- deadWallet = 0x000000000000000000000000000000000000dEaD (#480)
Use: Ether suffix, Time suffix, or The scientific notation
