Sales are the first live Tucker rail. A Tucker is earned only when a verified AI-attributed sale survives 120 days with no refund or chargeback. Other settled value rails are future approved rails and do not mint Tucker yet.

A Tucker can be transferred exactly once — a single hop — and it cannot be passed on again. And it can always be withdrawn.
