Launch models, explained plainly

A market's swap fee is split between the creator and the protocol in shares fixed at creation. The protocol takes 10% of fee revenue, capped by contract at 20% for any future market, and the creator receives the rest — so on a 1% swap fee the creator's share is 0.9% of the trade and the protocol's is 0.1%.

The creator's share is not a field on the launch form, and that is deliberate. It is whatever the fee leaves after the protocol's share, which means it cannot be set to a number the contracts would refuse, and there is only one contract that owns the arithmetic.

Two steps, both permissionless

• Collect. Fees accrue inside the locked position until someone calls collect on the locker, which moves them to the market's splitter. Anyone may call it, for any market, at any time.
• Claim. Each recipient then claims their own balance from the splitter. Nothing is ever pushed to a recipient, so a recipient that cannot receive ether cannot block anyone else's claim.

Which currency you earn in

Because the fee is charged by Uniswap rather than skimmed by the hook, it accrues in whichever currency was paid in: ether from buys, and your own token from sells. That is the trade-off of a hook that cannot take custody, and it is stated on the launch form rather than discovered on the first claim.

Nobody can redirect it

The recipient address is immutable for the life of the market. There is no owner, no admin key and no takeover authority — if a project changes hands, the fee stream does not follow unless the recipient was a contract that already allowed for it. Choosing a multisig or your own splitter at launch is the way to keep that option.
