Mint a piece

This page covers buying a piece straight from a collection: what the mint page shows you, who is allowed to mint, and what every message on it means.

Open a collection’s mint page, pick how many you want, and tap Mint. The piece lands in your wallet and shows up under My pieces.

What the page shows

• Cover art, the collection name, the creator and a link to the contract.
• Browse N pieces, which opens the collection’s page with every piece in it.
• Base / Solana, the network the collection lives on.
• A row of short labels telling you what the collection offers and what the creator can still change:
  • Sells back any time when the collection’s Vault holds money to buy a piece back. Every minted piece is in the Vault when holders have sold every minted piece back and the Vault still holds money. Otherwise the label reads Vault holds nothing to pay out. The Vault’s share of a trade counts toward Vault Backing and the Vault Exit once it is booked, at the next mint or Vault sale.
  • Art is showing or Hidden until reveal
  • Art locked in before minting, if the creator recorded a fingerprint of the set before the sale. The contract stores it and does not check the art against it; anyone can check the files against it.
  • The resale royalty, such as 5% resale royalty
  • One label for the art, from what the collection’s contract enforces:
    • Reveals the locked-in art only while the art is hidden on a collection that sealed its art at launch. Its reveal can publish that art and no other.
    • Art locked forever once the art is frozen, and on a sealed collection once it has revealed: the only art its contract accepts is the art already showing.
    • Art can still change on a collection that sealed nothing and is not frozen. Its creator can point the pieces at new files until they freeze. Art locked in before minting does not change this label.
    • Until the page has read from the chain whether the art is sealed, it shows no art label, unless the art is already frozen.
  • Paused, when the creator has paused minting
• How many pieces are minted and how many are left.
• The phase that is open now, headed Mint, with what the next piece costs, top-up included. When no phase is open, the page says so.
• Under it, The Vault: what the Vault pays for any piece today, from its Vault Backing less the 10% the Vault keeps and the royalty. While it holds nothing to pay out, the same place says how it fills.
• One line just for you, such as “You can mint · up to 4 at a time”, “You’re on the list · up to 4 at a time”, or the reason you can’t.
• A quantity picker, your total, and a note on the network fee: ”+ a small network fee”, which comes out of your USDC.

Prices are in the collection’s coin. Each collection is priced in one coin its creator picks at launch: USDC by default, or any other coin on Base. Every price on that collection is in that coin. On Solana the coin is SOL, USDC or another Solana coin.

Who can mint

You can mint when all of these are true:

1. A phase is open.
2. Pieces are left, in the collection and in this phase.
3. Your wallet is on the list, if this phase has one. The page asks when it opens, and Mint stays off until the list has answered.
4. You are under this phase’s limit per wallet.
5. Your wallet holds enough of the collection’s coin for the price.

The page checks these before you tap. If one fails, the Mint button stays off and the line above it says why.

How a mint works

1. Log in. Google, Apple, email, Base, X or Telegram. A wallet is made for you.
2. Choose a quantity. For a paid mint, you see the price, KURV’s 5% mint fee, the creator’s chosen share of what is left, and any Vault top-up, before you buy. On a phone, tap Where your $X goes above the button to read that split.
3. Tap Mint. You confirm once. Payment and mint go out together as one operation, with your network fee taken from your USDC.

A free mint shows KURV’s service fee before you mint: $0.25 for each piece, charged in the collection’s coin, paid by you as the person minting. See Fees for the full schedule and Gas and network fees for how the one-operation flow works.

You get the next piece in line.

Vault top-up

Every paid piece brings the Vault at least the Vault Backing per piece, so the pieces already out keep their backing. When the part of the phase price that reaches the Vault is less than that, the mint adds the difference on top of the phase price, and all of it goes straight into the Vault. KURV’s 5% and the creator’s share are taken on the phase price only.

A phase priced at $10, a creator share of 50%, and $8 of Vault Backing per piece:

Line	Amount
Phase price	$10.00
KURV’s 5%	$0.50
Creator, 50% of the $9.50 left	$4.75
Vault, from the price	$4.75
Vault top-up	$3.25
You pay	$13.25

The Vault receives $8.00 in all. The mint page shows the top-up in your total before you pay.

A phase launches with the price you set, fixed or rising, and Your collections has no control to change it. On a rising price, each piece costs a little more than the one before, so what the next piece costs changes with every mint. The page always shows what the next piece costs, top-up included.

You cancelled the transaction in your wallet.	You didn’t send it. Nothing was charged.	Tap Mint again when you’re ready.
The network rejected the mint.	The mint failed. Nothing was charged beyond the network fee.	Check the mint is still open, then try again.
Confirming…	Not an error. The network is writing your mint.	Give it a few seconds. Wait for it to finish before you mint again.

Selling back to the Vault is never paused and never closes with the mint: every piece a collector holds still sells back to its Vault whenever the Vault holds money.

If a mint takes longer than usual, it may still go through. Open the transaction link before you try again, so you pay once.

After you mint

The page says Minted! You got #N and shows your piece with a link to the transaction. You can tap Share or Mint another. On a wide screen, See the collection opens the collection’s page with every piece in it, and See the contract opens the same contract link as the top of the page. The piece also shows up under My pieces.

Free mints

A free mint has a piece price of zero. KURV’s service fee is $0.25 for each piece minted, charged in the collection’s coin, not per transaction, so four free pieces cost $1.00 in total. In another coin it is the same 25 cents at that coin’s price, set by KURV.

Free pieces	KURV service fee
1	$0.25
4	$1.00

You pay this fee as the person minting. Network costs are separate. See Fees for the full schedule, and read Risks and disclaimer before you mint.
