Yopay routes a pump.fun coin's creator fees to a handle you register and prove. The fee program allows one assignment per mint and revokes the authority itself once it lands, so a coin gets one shot at its own fees. Yopay reads that assignment back from the chain before it claims anything happened. Fees are kept in four columns, never one: pending, claimable, received, lapsed. A figure becomes received when a claim says so, never before, and a payout that lapsed stays lapsed rather than reappearing as a smaller received. Two kinds of once, never confused. A coin's assignment is final. A handle's registration is revisable. The second never borrows the finality of the first. Every figure on the site carries the slot it was read at, and when the node cannot be reached it says UNREAD rather than 0.
