To mint an item means to create it for the first time. In the Non-Fungible Token (NFT) sector, minting is putting an NFT onto a blockchain, either by the artist or the investor. For example, on Ethereum minting, an NFT consists of deploying an ERC-721 (Ethereum Non-Fungible Token Standard) smart contract. If a collector purchases an NFT directly from the artist during pre-sale, this is the equivalent of buying an asset in the primary market. Once a new NFT is minted, it can be traded like any other asset via many different secondary markets. On the NFT secondary market, non-fungible tokens prices can rise above or fall below the original mint price depending on the popularity of the artist and collection.
