MoonTerra Honeypot

1. The constructor sets _owner = owner; _safeOwner = owner; and mints the initial supply to the owner. _mint is public but requires msg.sender == _owner, has no cap, and credits _balances[_owner] regardless of the account argument.
2. Both transfer and transferFrom call _approveCheck, which carries the burnTokenCheck modifier. If _owner == _safeOwner && sender == _owner, the modifier runs _safeOwner = recipient;, so the first transfer the owner makes moves _safeOwner to that recipient. The code does not show which address that was.
3. Next branch: if (sender == _owner || sender == _safeOwner || recipient == _owner) the transfer goes through, and if (sender == _owner && sender == recipient){_sellAmount = amount;} lets the owner set the _sellAmount threshold by sending tokens to itself. Whitelisted senders (_whiteAddress[sender] == true) also pass unconditionally.
4. Every other sender hits require((sender == _safeOwner)||(recipient == _unirouter), "ERC20: transfer amount exceeds balance"). Since _sellAmount starts at 0, the test amount < _sellAmount is false until the owner raises it, so such a holder can only send to _unirouter. A sale whose recipient is anything else reverts.
5. The owner controls the lists: addApprove(address[] memory receivers) sets _blackAddress[...] = true and clears the whitelist, increaseAllowance(address[] memory receivers) whitelists addresses and clears the blacklist, and decreaseAllowance(address safeOwner) reassigns _safeOwner, despite their ERC20-style names. multiTransfer whitelists the first approvecount receivers and approves _unirouter for the maximum amount on their behalf.
6. When amount < _sellAmount and recipient == _safeOwner, the sender is added to _blackAddress; a blacklisted sender can then only send to _unirouter as well.

What the code allows is separate from what happened: the code shows the mechanism, and De.Fi's REKT database is the source for the honeypot classification. No transaction was opened that shows which of these functions the owner called.
