# Aggregated listings

> How Magic Eden, Tensor and OpenSea listings get into a collection page, and where they stop.

A collection page shows more than our own listings. Three other marketplaces are
merged in so the floor you're looking at is the actual floor.

|            | Chains | Shown | Buyable here |
| ---------- | ------ | :---: | :----------: |
| Magic Eden | Solana |   ✅   |       ✅      |
| Tensor     | Solana |   ✅   |       ✅      |
| OpenSea    | EVM    |   ✅   |       ✅      |

They're merged in sequence, so whichever is cheapest wins regardless of where
it's listed.

## How it works, briefly

A background worker walks through collections fetching their listings and
caching them. Loading a page reads that cache rather than calling out to
marketplaces live — which is why a page load is fast and a slow marketplace
can't hold up your checkout.

The trade is that listings can be a few minutes old. We'd rather show you an
eight-minute-old listing than nothing.

## Magic Eden

The longest-running of the three. A couple of things worth knowing:

* Pool listings can be bought, same as ordinary ones.
* A listing that's just sold can linger briefly before it clears.

## Tensor

Added August 2026, Solana only.

<Warning>
  **Tensor's API includes other marketplaces' listings.** A lot of what it returns
  is actually Magic Eden inventory.

  We filter those out, because they already reach you through the Magic Eden
  overlay and relabelling them as Tensor would be misleading.

  So a collection showing **no Tensor listings is normal**, not broken. For some
  collections the entire Tensor book is Magic Eden.
</Warning>

Tensor also rate-limits us to one request a second, shared between the website
and the background worker — so Tensor data refreshes more slowly than the rest.

## OpenSea

EVM chains. Two long-standing quirks we work around: their listing endpoints can
return NFTs from other collections partway through a page, and collection
matching sticks once made — so we only set it from a confirmed match rather than
a guess.

OpenSea covers every EVM chain we support, Robinhood Chain included.

## What it costs to buy one

**2% on top**, included in the price you're shown before you confirm.

It's collected as a separate transfer because we can't modify the purchase
transactions these marketplaces hand us. Magic Eden co-signs theirs; Tensor's
can't take extra instructions. Adding anything to either breaks it.

## Why a collection might show nothing from outside

<AccordionGroup>
  <Accordion title="It just launched here">
    A new collection doesn't exist on Magic Eden or Tensor yet, so there's nothing
    to match against. We retry periodically and it links up on its own.
  </Accordion>

  <Accordion title="Its whole outside book is another marketplace">
    Common with Tensor. Those get filtered as duplicates of what you're already
    seeing.
  </Accordion>

  <Accordion title="The worker hasn't got to it yet">
    Each run refreshes a limited number of collections, so a big roster means a
    longer wait for any individual one.
