In Ergo you can mint NFTs without a third party application. NFTs on ergo are 100% native, and don’t require the user to pay for gas fees or insane fees (cough cough.. Ethereum). You can create NFTs for less than a $1 on the Ergo platform! This is a great way for content creators to access a new market, and to also store their art for eternity, since once minted, it will live on the blockchain forever.
