On the marketplace, you can not only sell your animals, equipment and convoys but also buy a new one for gameplay. Furthermore, you can even purchase a convoy and reassemble and then trade it to profit!
Please note that the animals would keep starving and go into a dying state during listed period if there is no ongoing contract.
When selling an NFT on the Marketplace, a 10% tax will be applied and these taxes will go entirely to the rewards pool.
