Drops FAQ

Do collectors pay gas fees when minting?

Yes. Gas fees occur for any transaction or attempted transaction on the blockchain including a mint. The amount will vary depending on a variety of factors such as how many people are using the network at that moment. OpenSea does not control gas prices, nor does it receive or profit from them, and OpenSea is not able to refund gas fees. You'll pay gas fees even if you weren't able to successfully mint an item.

How can I reserve items for my team?

To reserve a certain number of NFTs for your team, you can set up a team allocation stage by creating a presale stage with a 0 ETH mint price.

You may want to create a single wallet address for this stage with a per-wallet limit of the total number of NFTs you'd like to allocate to your team. You can mint the entire team allocation to a single wallet when the presale stage begins, and send the NFTs to team members as needed.

Can items reveal as they mint, instead of after the drop ends?

Not through OpenSea Studio. The reveal step becomes available once a drop mints out, and it publishes metadata for every item at once.

You can do it yourself by hosting the metadata instead of pinning it up front. Point your contract's baseURI at a server you run, and have it return real metadata for token IDs that are minted and a placeholder for the rest. Buyers see their item seconds after minting, and nothing about an unminted item is public, so there is no mapping to snipe. After the drop mints out, pin the finished metadata to IPFS and set baseURI back to it.

instant-reveal-drop-metadata is a reference implementation of that server, deployable on Cloudflare Workers, Vercel, or any Node host. You run and maintain it yourself; it is not a hosted OpenSea product.
