How to sell your art with an NFT certificate, no gas fees
3 min read · Updated 2026-10-30
You don't need to learn crypto to sell your art with an NFT certificate. On ChainChum you list your real work like you would on any handmade marketplace, certify it once for a small fee, and the NFT certificate follows the piece to its buyer and every owner after. No gas fee and no wallet.
Step by step
- Sign up with email and confirm you are 18 or older.
- Open your shop for free: a name, a short bio and your shipping settings. See Open your shop.
- Photograph your piece from your phone. The listing assistant suggests a title, medium, size and tags; you edit and approve everything.
- Pass the human-made check. Photos are screened for AI-generated images. Most listings pass in seconds, and anything unclear goes to a person.
- Set your price. The editor shows exactly what you receive: 95% of the sale.
- Publish and certify. ChainChum mints the work's NFT certificate on Base and pays the network fee. The one-time $1 certificate fee is shown before you publish and comes out of the work's first sale.
- Sell and ship. When the piece sells, the certificate transfers to the buyer, its QR code goes on your packing slip and you are paid to your bank.
Rolling out: shops and listings are live today. Card checkout, payouts and NFT certificates switch on with the first pilot sales.
What it costs
| Typical NFT marketplace | ChainChum | |
|---|---|---|
| Minting | Paid by you, or delayed until sale | One $1 certificate fee per work, taken from its first sale |
| Gas fees | Paid by you | Paid by ChainChum |
| Platform fee | Varies | 5% of what sells, card fees included |
| Monthly plan or ads | Sometimes | None |
| Resales and transfers later | Gas again | Recorded on the same certificate, free |
| Payout | Crypto to your wallet | Dollars to your bank |
Editions and royalties
Selling prints? List a limited edition of, say, 25 copies. Each copy gets its own numbered NFT certificate, such as 7 of 25, so buyers know exactly what they hold; the editor shows the certificate fee for the whole edition before you publish. When a piece is resold on ChainChum, you earn a royalty on the resale, paid through checkout rather than left to the buyer's goodwill.

Questions
Can I sell digital art with an NFT certificate?
Yes. Digital downloads sell with watermarked previews and a personal or commercial licence, and each one is certified like a physical work. AI-generated images are never allowed.
When do I pay the certificate fee?
Never upfront. The $1 fee is charged when you publish and taken once from the work's first sale, so a work that never sells costs you nothing. There is nothing to pay again when it is resold on ChainChum or passed on: ChainChum records every later transfer on the same certificate for free.
What happens to the certificate if the piece doesn't sell?
It stays yours. The certificate is tied to the work, not to a sale, so it is ready whenever the piece finds a buyer, here or later.
Can buyers trade the NFT?
Not on ChainChum. A buyer who exports the token to their own wallet can trade it on other NFT marketplaces, and the verify page shows such a transfer as off-platform until the new holder claims it. Reselling the artwork on ChainChum keeps the certificate with the piece and pays you a royalty.
