Tent offers a flat pricing model regardless of the amount of ADA or NFTs traded:
For every trade, each user has to pay only 5 ADA.
Fort Gotten holders enjoy a special discount. If you hold a Fort Gotten Kid (Ep 0, 1, or 2) in your wallet, you will automatically receive a 50% discount on trading fees, paying only 2.5 ADA per trade. This only applies to the holder's wallet.
