Space SIP allows the players to own their minted NFTs (characters and items). The right to sell and trade is wholly owned by the player. Space SIP implemented a market to make this process trustless. The player can search ships and items that have been listed by other players, as well as list their own characters and items.
The player will spend a nominal BNB gas fee to list or un-list the characters and items to/from the marketplace.
The platform takes a 5% exchange fee on top of listing price. This fee goes directly into the contract used to give combat payouts.
