Minting a Uniq

On the factory page, search for issue action in the search box, and click on the Issue tokens (eosio.nft.ft::issue.b) action to open up the transaction modal.

Once you have inputted all the values, click on the Send 1 Action button and it will open up the transaction confirmation modal. You can click on the Details button to view the transaction in JSON form. Click on the Confirm button to submit your transaction.
