A contract for trading NFTs on Polymesh.
Allows NFTs to be sold safely for POLYX. The NFT transfer and POLYX transfer are done in a single atomic transaction to ensure the seller get their POLYX and the buyer gets the NFT.
Sellers set the price they are willing to sell each NFT for. Then buyers can pay that price to receive the NFT. The NFT stays in the seller's portfolio until the buyer pays for it.
