A sweep lets you buy several items from the same collection in a single signature. You pick the items (or use the cheapest-N slider), the wallet signs once, and the backend fans the order out into N atomic purchases. Some may succeed and some may fail — that's a partial fill, and it's normal.
Pick the items you want
On the collection page (
arkena.io/collection/{id}), build the bundle two ways: drag the slider in the bottom bar to grab the cheapest N, or click the + on any listed card to pick by hand. Both update the same selection — the running total ticks up as you add.Live preview · drag the slider, click a cardarkena.io/collection/genesis 0Floor 15.00 CC·4 listedReview and approve
Hit Buy in the bottom bar. The wallet popup opens with the full bundled order — every selected item, the per-item price, the total CC required, and the aggregate fees.

Awaiting signatureApprove once
One signature covers the whole bundle. Behind the scenes, the backend splits your signed intent into one purchase per item and submits them in parallel. Each item settles atomically — you either get it or you don't, but the rest of the bundle doesn't depend on any single one succeeding.
Confirm the receipt
After settlement, you'll see a per-item receipt: which ones landed, which ones were lost to a faster buyer, and any refunded CC.

Submitting in parallel — sub-second finalityRace losses happen — someone else bought the same item in the few seconds your sweep was in flight. That item just doesn't ship. Your wallet is debited only for the items you actually received.
When part of a sweep fails
The most common reasons:
- Race-lost. Another buyer bought the item between your page load and the moment your sweep landed.
- Listing expired. The seller's listing reached its expiration in the meantime.
- Insufficient CC for the full bundle. If you don't have enough for every item, the wallet rejects the whole sweep at signing time. None of them are attempted.
A partial fill is not a bug — it's the protocol behaving correctly. You were never debited for items you didn't get.
