You can just create it, and you don’t have to put any electronic currency in it. So leave it as it is and move on to the next step.
The operating procedure on OpenSea is that you have to build your collection to create your NFTs.
Once your collection has been created, you can assign it a name, a picture, a logo, give it a description or even customize its URL.
Since we’re focusing on making NFTs for free, we’ll choose the Polygon blockchain. Polygon doesn’t require any gas fee.
Congratulations! You’re ready to start minting NFTs.
