NFT certificates
Buying art with an NFT certificate by credit card, no wallet needed
2 min read · Updated 2026-10-30
On ChainChum you are buying the art, not an NFT. The NFT is the piece's certificate of authenticity, and it comes with every purchase. You buy the way you buy anything else online, with a card, Apple Pay or Google Pay, and the certificate transfers to you automatically.
Step by step
- Find a piece on Explore. Filter by category, price or family art, or search by artist or tag.
- Check the badges. "Human-made" means the photos passed screening, and every seller is a verified adult. "Original" or "Edition 3 of 25" tells you exactly what you are buying. The certificate ID on the page opens its public verify page.
- Sign in with email or Google and confirm you are 18 or older.
- Pay by card, Apple Pay or Google Pay. Prices are in US dollars, and sales tax is shown before you pay.
- Receive the work. The seller ships the real piece and you track it from your account; a digital download is ready as soon as you pay.
- Receive your NFT certificate. It is transferred to you on Base when the order completes, emailed as a PDF and shown on a public verify page. ChainChum pays the network fee.

What you pay
You pay the listed price, shipping and any sales tax. There is no buyer fee, no certificate fee and no gas fee: the seller's one-time certificate fee comes out of their first saleed the work, and ChainChum's 5% comes out of the seller's side.
Where the NFT lives
ChainChum keeps a wallet for you, so there is nothing to install and no phrase to write down. Your certificates appear in your account. If you already use a wallet, you can export the token to it at any time, and from there it can be moved or traded on other NFT marketplaces like any ERC-721 token. ChainChum itself never trades tokens.
Questions
Can I buy with a debit card?
Yes. Any card that works online, plus Apple Pay and Google Pay, works on ChainChum. Payments are processed by Stripe.
Do I need to know anything about crypto?
No. You never see coins, keys or fees. The NFT is recorded behind the scenes, and you can learn more in What is an NFT? if you are curious.
Can I sell the NFT afterwards?
Not on ChainChum: tokens are never bought or sold here. To sell the artwork, relist the piece on ChainChum and its certificate goes to the next owner, with the resale added to its history for free. If you export the token to your own wallet, you can trade it on other NFT marketplaces, but the certificate is meant to stay with the piece.
Can I return a piece I bought?
Returns are planned within 14 days for originals and prints, with the certificate moving back to the seller. The buying guide has the details.
