When you use the “Create an NFT” feature in OpenSea Studio, you can’t bulk-upload multiple NFTs at once. You’ll need to create each one individually, though you can set the supply quantity to be more than 1 if you’d like to mint multiple copies of the NFT.
However, you can upload your media and metadata in bulk when you prepare a Drop. Learn more here.
At this time, we don’t support creating generative NFT collections based on specified traits and rarity.
You can use a variety of file formats for images, videos, or audio to make your NFT. We currently support JPG, PNG, GIF, SVG, and MP4 files. The maximum supported file size is 50 MB.
Collection collaborators can modify your collection settings. Keep in mind that collection collaborators can’t add new items or edit creator earnings recipient addresses or creator earnings percentages.
To add a collection collaborator, navigate to OpenSea Studio and find the collection you’d like to update. Click Edit details. On the Details tab, click + Add collaborator and enter their wallet address or ENS name. Click Submit.
Once you’ve minted an item using OpenSea, it will exist on the blockchain you’ve chosen and be visible on that blockchain’s explorer, such as Etherscan. It should also appear by default on any other marketplace that supports your blockchain.
OpenSea does not receive any fees when you use the “Create an NFT” feature in OpenSea Studio.
You will, however, need to pay gas fees to deploy your smart contract and mint the NFT. Gas is paid to validators on Ethereum, not OpenSea, and is the cost to process a transaction. Gas fees will vary depending on how busy the blockchain network is, and which chain you use to launch your collection.
The maximum file size is 100MB for all media, but we recommend 10MB-15MB for images. You can add a maximum of 50 sections to your page.
