One charges a fixed LP fee. Another uses a hook to change the fee for each swap. A third checks the caller, modifies accounting or rejects the operation under conditions your reserve calculation does not model.</p> <p>For a bot, a pool&rsquo;s price is therefore not enough to describe the trade. You need the pool key, hook address, execution path and state used for simulation. A successful quote through one caller does not prove the same swap succeeds through your executor.</p>
