Package market trades Launchpad NFTs: fixed-price listings and funded offers. A sale pays the seller, the treasury and the collection's royalty receivers inside the same transaction. The realm holds only the escrow of open offers, which their buyers can always take back, and has no admin. It keeps open orders only: a closed one is deleted, so its storage deposit is released, and its history is the event log.
GetListing returns an open listing; a closed or unknown ID aborts.
