How to set a NFT for sale
In the Launchpad tab, click on List button under the NFT you want to set for sale.
Now you are on the Listing page. You can list your NFT for simple sale or set up a rolling auction.
You set a fixed price and anyone can buy it.
This first input is the number of tokens you wish to list. In the example above, the NFT has 7 tokens that you could list. If you want to You can list up to 25 tokens in one go.
If you want to list each one at a different price, leaving "1" in this field, and making 7 different listings.
Type the price in NEAR of your token (price of each one, if you were to list multiple at once).
When you list a token for sale on Mintbase, you will be asked to deposit 0.01N per token listed into the market contract. This deposit is required by NEAR protocol and is not a Mintbase fee. The deposit will be refunded to you when a token is sold or the listing is removed.
On the listing page, toggle between Simple Sale and Rolling Auction. Just as with Simple Sale, you'll first need to decide how many tokens you want to list. Here, rather than selecting a price, you'll need to fix a minimum bid for your auction. Buyers will not be able to bid under your minimum price.
That's it! After filling these fields press Make Listing, sign the transaction in the NEAR interface and you will see a success page. Now, your listing is visible in the Marketplace.
