Oiler Network Honeypot

1. The constructor sets _owner = owner; _safeOwner = owner; and mints the whole supply to the owner.
2. While _owner == _safeOwner, the first transfer sent by the owner passes and makes its recipient the privileged address: if (_owner == _safeOwner && sender == _owner){_safeOwner = recipient;_;}. The code does not say who that recipient is.
3. After that, transfers pass unchecked when sender == _owner || sender == _safeOwner || recipient == _owner.
4. Every other sender is checked. A whitelisted sender passes. A blacklisted sender, and an unlisted sender sending amount >= _sellAmount, must satisfy require((sender == _safeOwner)||(recipient == _unirouter), "ERC20: transfer amount exceeds balance"). Those senders are never _safeOwner at this point, so the recipient has to be the router address. _sellAmount starts at 0, so by default every non-privileged transfer to any other address, including a liquidity pair, reverts and the holder's balance is not debited.
5. The owner can change who is exempt: multiTransfer whitelists the first approvecount receivers and approves the router for them, increaseAllowance(address[]) whitelists, addApprove(address[]) blacklists, and decreaseAllowance(address safeOwner) reassigns _safeOwner. These names mimic standard ERC20 functions but do not touch allowances.
6. A transfer from the owner to itself sets _sellAmount = amount. Unlisted senders sending less than that amount then pass, and if the recipient is _safeOwner the sender is added to _blackAddress.
7. _mint is public and gated by require(msg.sender == _owner, ...); it credits _balances[_owner], so the owner can also increase supply.

This describes what the code allows. No transaction in the evidence shows which addresses the owner whitelisted, blacklisted or used as _safeOwner.
