Marketplace: licences, fixed price, MPRO only

The Marketplace is where licences change hands. It is deliberately simple: fixed prices, settled in MPRO, atomic settlement — no bundles, no bidding wars, no surprises. It works in both directions: a For Sale listing offers a specific licence at a price, and a Wanted offer says "I am buying this many licences of this type, at this price each". The type filter at the top switches between them.

How selling works

1. Open Marketplace → Sell licence, pick the licence and set your price in MPRO.
2. You approve the marketplace for that one NFT — the licence never leaves your wallet while listed. No escrow, no deposits.
3. When someone buys, settlement is atomic: the buyer pays, the licence moves, you are paid — in one transaction, with a link to it as proof.
4. You can cancel a listing at any time. Your active and past listings live under My Auctions in your account menu.

What you receive is the listed price minus the marketplace fee and minus the token's burn fee — the interface quotes the exact take-home before you list, live from the contracts. The marketplace fee is a DAO-governed parameter with a hard ceiling written into the contract.

How buying works

Pick a listing, approve MPRO for the price, buy. The transaction settles everything at once and the licence is yours — the moment the purchase confirms, the platform reflects it and the licence appears on your list.

Read the listing with the licence rule in mind: a licence carries its unclaimed distribution with it. When you buy, everything the licence has accrued and not yet claimed becomes yours — and you do not have to take the seller's word for how much that is. Every listing shows the licence's unclaimed distribution, verified by MPRO Lab from the same records the payout uses. The seller cannot overstate it, and cannot quietly drain it either: a listed licence's distribution is locked for the duration of the listing — the platform refuses to mint from a licence that is up for sale, so what you see on the listing is what you receive.

Wanted — posting a buy offer

The mirror of a listing. Instead of waiting for the licence you want to be listed, you post what you will pay:

1. Open Marketplace → Wanted, pick the licence type (ggNODE or iNODE), how many you want, and your price per licence in MPRO.
2. You approve MPRO for the full amount — but the tokens never leave your wallet while the offer stands. No escrow, exactly as with listings: the approval is the commitment, your balance stays yours until someone sells into the offer.
3. Any holder of that licence type can sell into your offer, one licence at a time. Each sale settles atomically — their licence moves to you, your MPRO moves to them — and the offer's remaining count goes down until it is filled.
4. You can change the price, change or remove the expiry, or cancel the offer at any time. Cancelling costs nothing, because nothing was ever deposited.

The offer is bound to the licence type. The contract itself guarantees that an offer for ggNODE can only ever be filled with a ggNODE — what you asked for is what you receive, enforced at execution, not by the interface.

Price the licence, not its balance. Sellers will most often claim their accrued MPRO first and sell an empty licence into your offer — that is rational and allowed. If a seller does sell a licence with unclaimed distribution, it comes with the licence and becomes yours, and the interface shows the seller the verified amount before they accept — so nobody sells accrued value by accident.

Expiry — optional, on both kinds

Both listings and offers can carry an expiry date. Leave it empty and it never expires; set it and it ends itself at that moment, no transaction needed. You can add, move or remove the date at any time on your own listing or offer. The one rule: an expiry must be at least one hour ahead — the contract refuses anything shorter, so a mistyped date cannot kill your offer the moment you post it.

An expired listing cannot be bought and an expired offer cannot be accepted — the contract refuses, whatever the interface shows.

The fine print that is not fine print

• Listings are per licence — one NFT, one listing.
• Only licence collections approved by governance are tradable; the allowlist is a DAO decision.
• The Completed tab shows finished sales, each with its transaction.
• Prices never change silently: the contract refuses a purchase above the price you saw.
• A listed licence keeps earning its daily share — it just cannot be minted until the listing ends, by sale or by cancellation.
• A Wanted offer is only acceptable while the buyer's wallet still holds the MPRO and the approval behind it. If either is gone, the offer shows as stale and cannot take anyone's licence.
• Selling a licence into an offer automatically ends that licence's own For Sale listing, if it had one — a licence is never sold twice.
