For my art project SWIMM · A, I mint unique ERC-721 NFTs on Ethereum using my own Manifold Creator contract.
I would like to prepare fixed-price listings in advance so that sales become available at a specified future date and time, ideally on Manifold, OpenSea and Rarible.
Could you please clarify:
When I create a Flat Price listing on Manifold , is the NFT transferred from my wallet into the marketplace contract immediately, even if the sale starts in the future?
Can the same NFT have executable fixed-price listings on OpenSea and Rarible while that Manifold listing exists?
If this is not possible, is there a supported way to make one NFT purchasable through all three platforms, perhaps through aggregation of a single listing?
Once I have completed the required wallet approvals and transactions beforehand, will the scheduled Manifold sale become active automatically, without another signature or my being online at the start time?
I am asking about selling an already-minted NFT , rather than scheduling a mint or drop.
Thank you for helping me establish a reliable workflow.
Yes. When you create a Flat Price listing on Manifold, the NFT moves from your wallet into the Manifold marketplace contract in that same transaction, even if the sale starts days later. It stays there until it sells. If you want it back, click Unlist on the listing’s page in Studio and it returns to your wallet (one transaction, costs gas).
No. While the NFT is held by the Manifold marketplace, it isn’t in your wallet, so a fixed-price listing on OpenSea or Rarible can’t be filled. Those listings stop working until the NFT is back in your wallet.
Manifold doesn’t have a way to make one listing buyable on OpenSea and Rarible as well. For a single 1/1, it can be for sale in one place at a time.
Yes. When you create the listing, you set the Start Time and End Time and sign once. The sale opens on its own at the start time; you don’t need to sign again or be online. The start time has to be at least 5 minutes away when you sign, and the times are in your local time zone. Before the sale starts, you can still change the price or times from the listing’s page in Studio, with one more signature.
Thank you, that clarifies the custody and scheduling questions.
My main goal is to make each work visible on Manifold, OpenSea and Rarible, with a simple path to purchase. I do not necessarily need three separate listings.
On my public Manifold token page, “View on” opens the existing OpenSea and Rarible pages. OpenSea shows “List for Sale” when I am connected as the owner, while Rarible shows “Not Listed” and “Make offer”.
Could you please clarify:
Are these public token pages already visible to other visitors without me creating a listing on OpenSea or Rarible?
If I create a scheduled Flat Price listing on Manifold, will the token remain visible on both platforms while it is held by the Manifold marketplace contract?
Will either platform show the Manifold sale price or provide a direct link to purchase on Manifold? Or will the item simply appear as not listed there?
If there is no automatic purchase link, what is your recommended way to direct someone from the OpenSea or Rarible token page straight to the corresponding Manifold sale?
Would setting the NFT’s External URL to its Manifold sale page achieve this, and is that sale URL stable?
I would like to prepare everything in advance, have the sale start automatically, and avoid making collectors search for the artwork again on another website.
Yes. OpenSea and Rarible build those pages from the blockchain, so anyone can see them whether or not the piece is listed there.
Yes. While the Manifold marketplace holds the token, both sites show the marketplace contract as the owner (“ManifoldGallery” on OpenSea).
Neither shows the Manifold price or a buy link; the item appears as not listed. Rarible shows listings from some other marketplaces, but not Manifold.
and 5. Yes, use the External URL. Point it at your Manifold token page (manifold.xyz/@yourname/contract/…/tokenId) rather than the sale page: the token page address stays the same, and while a listing exists it shows a Listing card that opens the sale. A sale page address belongs to one listing, so a new listing gets a new one. OpenSea shows the External URL as a link on the item page. Rarible doesn’t show it on the token page, so for Rarible visitors, add the Manifold link to the token’s description, which Rarible does show.
For one link to everything you have for sale on Manifold, use SWIMM · A · Marketplace | Manifold. That address doesn’t change either. To set the External URL, edit the token in Studio; it’s under “Show advanced properties”, next to the description. Saving takes one signature and doesn’t affect the listing, so do it before or after you list. Then create the scheduled Flat Price listing, and the sale opens on its own at the start time.
