If you've enabled Marketplace support for secondary trading on your Auction House - you're able to adjust the % fee that you want to charge sellers.
You can select any % fee you want to, along with updating the fee receipent address - which is initially set as the Admin wallet address you used when deploying the Auction House.
By default, a 2% protocol fee is applied to every sale.
This cannot be adjusted and goes to the protocol rewards pool.
