OpenSea.io is currently the largest NFT marketplace on the web and a great place to get your feet wet for anyone new to minting their own NFTs. Here are some stepping stones to help you avoid noob mistakes.
Recently, I posted an article about how to mint music NFTs on OpenSea.io. At the end of the article, I added some tips to help readers not make noob mistakes. I decided that the topic deserves an article of its own.
Here are the top 10 noob mistakes that people make the first time out minting NFTs on OpenSea.
Minting and managing your NFTs can be exciting. But it’s important to not be in a hurry. On my first time out, I personally lost a small bit of ETH by being too quick to sign an ETH transaction. I thought I accepting an offer. At the time, gas fees were over $100 so I jumped at what looked like a $10 gas fee not realizing that it was for something else — I know not what to this day.
Slow down. Triple-check every form and every popup, and stare down every wallet action before you click “sign.”
First, you have to create a collection for your NFTs on OpenSea. Then you add the individual NFTs within that collection. And the moment you sell the first NFT on OpenSea, the entire collection goes onto the Etherium blockchain. Adding more NFTs after that costs more ETH. (You can also use the Polygon blockchain.)
It’s important to get all of your existing NFTs into your collection before you list any for sale. As you add each item, it shows up in the marketplace even if it’s not listed for sale. If someone really wants to buy it before you get the entire collection ready, they can make an offer — hopefully one you can’t refuse.
