The Black Market is place for players to sell their excess items and purchase from other players. With the exception of auctions, the black market is filled with items by other players.
Auctions are run by the Black Market over a period of 3 days and offers 1 of each standard character starting at 500WP. Your bid in WP will be held until your are outbid by another player or the auction ends and you are the winner.
If you win you will receive the character NFT in your account, and the Black Market keeps what you bid for the NFT.
Buying, selling and auctions are all on-chain actions which consume stamps (TAU). You are buying, selling or bidding on NFTs which will be moved between accounts on successful completion of purchases.
Selling items attracts a 15% fee which the Black Market keeps.
