You will need to navigate to the “my NFTs“ section on your profile and click on the particular NFT that you would like to list for sale. Before you do so, you will need to ensure if your NFT belongs to the ERC-721 category or the ERC-1155 category.
If you have chosen an ERC-721 NFT, you will have an option to either list your NFT for direct selling or for bidding or for both.
If you have chosen direct selling, you will have to enter the sale amount. If you have chosen to list the NFT for bidding, you will have to list the minimum bid amount. If you have chosen both options, you will need to list a sale price and a minimum bid.
If you have an ERC-1155 NFT, you can only put it up for direct selling.
