From the Sell tab, tap "List an item." Pick a category, fill in the details specific to it, add 3–10 photos, choose a cover photo, and set your price. Tap publish and it's live — there's no approval step and nothing to wait for.
Our team keeps an eye on listings after they go up. If yours breaks the rules we'll take it down and tell you exactly why, so you can fix it and list it again.
