Listing and delisting on the hyperspace contract
For the beta we will start with allowing users to be able to list and delist NFTs on the hyperspace contract. The Hyperspace contract takes a .5% platform fee that the seller pays. It allows for builders to add custom fees on either buyer or seller side.
