nsmarket/v2 package

nsmarket — names for sale, without anybody holding anything.

HOW A SALE WORKS, and why it is built this way.

The seller keeps their name. Listing does not move it here: it records an asking price and relies on the GRC-721 approval the seller has already granted this realm. Ownership does not change until somebody buys, and the seller can walk away at any moment by revoking the approval — at which point the listing simply stops working.

The buyer's money is never held either. Buy is ONE call: it checks the listing still stands, moves the name, pays the seller, takes the fee, refunds any overpayment. All of it inside the transaction the buyer signed. If any part fails the whole thing reverts and nothing moved.

Which means: at no point does this realm hold somebody else's name or somebody else's money. That is not a nice-to-have. An escrow that holds either one is a different kind of business, with a different set of rules, run by people with licences.

THIS REALM HAS NO VAULT PRIVILEGES. It is not in nsdata's trusted set and does not ask to be. Every transfer goes through nslogic's ordinary GRC-721 path, which means it can only move a name the owner has explicitly approved — the same permission any other marketplace would need. However wrong the code below turns out to be, the worst it can do is fail.
