Listing a surface
A listing is one object you own, with one or more panels a brand can rent, each drawn at its real size.
Panels and their sizes
Start with a photo of the object. Draw each panel on it by clicking its four corners, then give the panel a name and its real width and height in centimetres. A 20 by 8 cm placement looks huge in a mockup and modest on the real thing, so the brand bids on the real size. One object can carry several panels.
Say where the object goes and how often. That is what a brand is paying for. Your listing must be accurate: the object, the panel sizes and where it is used.
The floor and the runs
Each panel has a floor: the lowest monthly rate you will take, at least 50 USDC a month. You also choose which runs you accept: 1, 3, 6 or 12 months.
A campaign is capped at 500 USDC in total, so a run only fits if the floor times the months is 500 or less. At a floor of 100 USDC, a 6-month run does not fit and is left out when bidding opens; 1 and 3 months do.
Opening bidding
You open bidding on a panel when you are ready, for 1, 3, 5 or 7 days. A bid in the last 15 minutes extends the auction by 15 minutes. Your listing needs to be verified before it can take bids (see Getting your pass).
The print check
Every bid comes with its artwork, and the artwork is measured against your panel’s size before you are asked to print it. The check works out the print density at the real size, in dots per inch:
| At the panel's size | Verdict |
|---|---|
| 200 dpi or more | Good for print |
| 150 to 199 dpi | Fine for print |
| 75 to 149 dpi | May print soft |
| Under 75 dpi | Too small to print at this size |
It also warns when the artwork’s shape is more than 12% off the panel’s, which means borders or cropping.
What a brand sees before bidding
Your photos, each panel drawn to scale with its size in centimetres, its floor, the runs you accept, and where the object goes. Whether the listing is verified. The bids so far, with brand names partly hidden and never their artwork.
