Fraktal enables anyone to mint a new NFT as an erc-1155 Token. To do this go to the mint page and make sure 'sell fraktions' is NOT selected.
Upload the NFT file (PNG, JPG, GIF), add a name, and enter the description.
Then click the Mint button and sign the transaction in metamask. Your NFT is now minted and can be viewed from the portfolio page.
