Gallery: buy, sell and offers
Hartii Gallery is an NFT marketplace on Quai mainnet. This guide covers browsing, buying, selling and offers.
Who it's for: first-time NFT buyers and sellers. You'll need: the Pelagus wallet (pelaguswallet.io) and some QUAI for the price plus gas. Add only what you intend to use.
1. Connect
- Open hartiigallery.com.
- Press Connect Wallet in the top bar and approve in Pelagus.
2. Browse
- Explore lists collections. Market (titled "Quai ERC-721 Market") shows items listed for sale, with a Listings tab, an Activity tab, search and price filters.
- Open a collection to see its price, supply and trust badges: Frozen (metadata sealed, art can't change), Mutable (the creator can still change it), IPFS, On-Chain Art, HTTP (least resilient) and Legacy Contract. Frozen plus IPFS is the strongest combination.
3. Buy an NFT
- In Market, or a collection's listings, find an item.
- Press Buy now (the button reads "Buy now · price").
- Confirm in Pelagus. Check the amount and the network.
- You will see "Purchased! This NFT is now yours." The item appears on your Wallet page and under Collected works on your Dashboard.
If you see "This listing is no longer available", someone bought it first and nothing was spent.
4. Sell (list) an NFT
- Open an NFT you own and press Sell / List.
- Type a Price (QUAI).
- Press Confirm.
- The first listing in a collection signs 2 transactions: a one-time marketplace approval, then the listing. Later listings from that collection need 1.
To cancel a listing: open your Wallet page, find the item under your active listings and press Cancel. Cancelling costs gas.
5. Offers
- Token offer: on an item page press Make offer, enter an amount in QUAI, pick an expiry (No expiry, 1 hour, 24 hours, 7 days) and send.
- Collection offer: on a collection page press Make Collection Offer. Any holder may accept.
- Your offer amount is held by the marketplace contract until it is accepted, expires or you cancel it.
- As a holder: on your Dashboard, Offers Received lists offers on your items, each with an Accept button. My Offers lists the ones you made, and you can cancel them.
Fees
| Item | Value |
|---|---|
| Marketplace sale (direct sale or accepted offer) | 2.5% platform fee, hard-capped at 5% in the contract |
| Creator royalty on resales | 0 to 8%, set by the creator |
| Primary mint | 5% platform fee |
| Gas | Paid to the Quai network in QUAI, not to Hartii |
The seller receives the price minus the platform fee and any royalty. The site's Fees page and Gallery contracts have the details.
Common mistakes
- Wrong network. Hartii runs on Quai mainnet. Verify every wallet prompt before signing.
- "Insufficient funds". You need the price plus gas.
- Transaction looks stuck. Look it up on quaiscan.io. Don't resend until you know whether it succeeded.
- Rejected in Pelagus. The site shows a cancelled message and nothing happens; just try again.
- Surprise art. Check the badges first: a Mutable collection's art can change.
