O5O Token

O5O.rescueBSC20(address,uint256) (#502-505) ignores return value by IBEP20(tokenAdd).transfer(owner(),amount) (#504)
O5O.burnBSC20(address,uint256) (#507-509) ignores return value by IBEP20(tokenAdd).transfer(deadWallet,amount) (#508)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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

Contract ownership is not renounced (belongs to a wallet)

O5O.slitherConstructorConstantVariables() (#361-514) uses literals with too many digits:
- deadWallet = 0x000000000000000000000000000000000000dEaD (#373)
Use: Ether suffix, Time suffix, or The scientific notation

Low level call in Address.sendValue(address,uint256) (#310-315):
- (success) = recipient.call{value: amount}() (#313)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
