SwapNFT.rescueAnyBEP20Tokens(address,address,uint256) (#769-772) ignores return value by IBEP20(_tokenAddr).transfer(_to,_amount) (#771)
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.

Contract ownership is not renounced (belongs to a wallet)

solc-0.8.16 is not recommended for deployment
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.
