Without a hook
The fees land in one wallet.
A pump.fun launch earns the creator a cut of every trade. Normally it accumulates quietly, one wallet claims it, and nobody who bought ever finds out what happened to it. There is no policy to read, so there is nothing to hold anyone to.
With a hook
The fees have a job, written down.
You attach a hook at mint. The split and the cadence are written into the coin's metadata before the first trade, so anyone can read what the fees are meant to do — and you can execute it, in public, whenever you claim them.
