How do I sell an NFT?

On the Wallet tab, open the item under NFTs and press Sell. Set a starting bid of at least 1 CRETA, in whole CRETA, and confirm.

The first time you sell from a collection, there is an extra approval step (Approve and list). It lets the marketplace hold the item while it is on sale. Each step costs a small POL fee.

The item moves into the auction while it is listed, so it leaves your NFTs list until the auction is settled or cancelled. The auction's length is set by the collection, and new bids can extend it.
