Publish and pricing

When your listing is ready, one press on Publish puts it in the marketplace. This page covers pricing, editions and what to expect after you publish.

#Setting a price

Enter the price in US dollars. Next to the price you will see ChainChum keeps 5% and You receive, the amount that comes to you when it sells. For example, a $60 piece pays you $57.

• There is no upfront cost. The certificate fee ($1 per work) comes out of the work's first sale (below). There is no monthly plan and no forced advertising.
• Card processing is included in the 5%.
• Shipping is charged to the buyer on top of the price, using your shipping profile.

#The certificate fee

Every work you publish is certified with an NFT certificate of authenticity. Originals and the first 25 copies of a numbered edition are certified when you publish; later copies, handmade goods and downloads when each one sells. The one-time certificate fee is $1 per work, shown in the editor, and it comes out of the payout of the work's first sale: if the work never sells, you pay nothing. ChainChum mints the certificate on Base and pays the network fee. Nothing is charged again later: the sale, any ChainChum resale and any inheritance are recorded on the same certificate for free. You can fix the title, details or photos until the first sale and the certificate updates itself; after a sale those are fixed, because a buyer holds the certificate. See Certificates of authenticity.

#Originals, editions and handmade goods

• Original: one piece, one buyer.
• Numbered edition: set the Edition size, for example 25 prints. When you publish, ChainChum creates numbered copies 1 to 25. Each buyer receives their own numbered certificate, and the work page shows how many are left.
• Handmade goods: set how many you have in stock.
• Digital download: no shipping profile needed.

#Publishing

Press Publish. If something is missing, ChainChum lists exactly what under Before you publish:

You will see	What to do
Give it a title	Add a title of at least three characters
Set a price	Enter a price of at least $1
Add at least one photo	Add a photo of the work
Set the edition size	Numbered editions need a size
Pick a shipping profile	Physical works need one
Pick the age bracket for family art	Choose the young artist's age bracket
Photos are still processing	Wait a few seconds and press Publish again

When everything is in place the listing goes Live and appears in Explore, search and your shop page.

#When a listing goes to review

Some listings are checked by a person before they go live, usually within one business day. The listing shows In review with the reason:

• A photo was flagged by the human-made screen. Our check thought an image might be AI-generated. A reviewer looks at it; if it is your own work, it is approved.
• Family-art copy is checked for a child's name or age. Descriptions that mention a child are read to make sure nothing identifies them.

#Changing your mind

• Unlist takes a live work out of the marketplace without deleting it. You can publish it again later.
• Delete draft removes a draft. Live works must be unlisted first.

#Royalties on resale

When a piece is resold on ChainChum, the original artist will receive a share of every resale. This arrives with certificates and resale; we will update this guide when it is live.

Next: Share your work.
