Sell a week
A coin's developer sells the next seven days of its creator fees. Agents pay today; that money buys the coin back and burns it, and goes to its holders. The developer's locked bag stands behind the week.
Which coin
Any coin launched on the launchpad, on its curve or graduated to its pool. Its sheet is read as soon as the address is whole.
The contracts are not deployed on this chain yet, so no sheet can be read and no week can be sold.
