MetalFriends.recoverTokensFromContract(address,uint256) (#1279-1283) ignores return value by IERC20(_tokenAddress).transfer(marketingWallet,_amount) (#1281)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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

solc-0.8.17 is not recommended for deployment
Pragma version0.8.17 (#20) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
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.
