Sale methods, phases and allowlists

This page covers the choices you make before you launch: how people buy, when they can buy, what they pay in, and who can buy. They are the How they get one and The price steps of the launch, the same on Base and on Solana, with only what a network has not left out.

Pick a sale method

Method	What buyers pay
Fixed price	One price for the phase. The Vault top-up on top of it depends on the Vault Backing at the moment each piece is minted, so what buyers pay can differ.
Mystery mint	One price for the phase. The Vault top-up on top of it depends on the Vault Backing at the moment each piece is minted, so what buyers pay can differ. The art stays sealed until you reveal it.
Rising price	Each piece costs a little more than the one before, from a first price to a last price you set. The Vault top-up on top of it depends on the Vault Backing at the moment each piece is minted, so what buyers pay can differ.

By default buyers get the next piece in number order. A collection can also draw the number at random, or let the buyer choose it.

A buyer pays the phase price, plus a Vault top-up when the part of that price that reaches the Vault is below the Vault Backing per piece: the difference goes straight into the Vault, and KURV’s 5% and your share are taken on the phase price only. Fees works it through.

A phase launches with the price you set, fixed or rising, and Your collections has no control to change it. To charge a different price, add another phase before you launch.

The launch steps can also sell by auction: a timed auction, or a falling auction that starts high and halves as it falls. On Solana, falling auctions open after a program update.

Rising price

A rising price is one way to sell, next to a fixed price and a mystery mint. Each piece the phase sells costs a little more than the one before, and the price changes with that and with nothing else.

You type a first price and a last price. KURV works out the rise from one piece to the next, so the price climbs evenly from the first piece to the last across the pieces the phase sells.
The first price has to be above 0, and the phase needs at least 2 pieces. A free phase cannot rise.
The phase needs a limit per transaction, so that one purchase cannot move the price by more than a quarter of the first price. The price step names the largest limit that works.
Each piece is charged on its own price, so KURV’s 5% and your share follow the price as it climbs.

Buyers see what the next piece costs on the mint page, and it changes with every mint.

Mystery mints

A mystery mint seals your art when you launch. Which piece is which stays hidden until you reveal. When you reveal, the collection accepts only the art it was sealed with, and the same signature freezes it, so the art people bought is the art they keep.

When you launch a mystery mint, you choose who sees a piece before the reveal:

I reveal the whole collection at once. Every piece shows the image before the reveal, to everyone, until you reveal. This is the default.
Each buyer sees their own piece as soon as they mint it. Logged in on KURV, the wallet that holds a piece sees its real picture and traits, marked as theirs alone. Everyone else sees the image before the reveal until you reveal the collection for everyone.

Set up phases

A phase is a window of time with its own price and limits. You can have one phase or several. A common setup is two: an allowlist phase, then a public phase.

Give the phase a name for your own reference, like “Friends” or “Public”; it shows on the review screen. Buyers see the open phase as Mint.
Set when it opens: Now, or Pick a time.
Set when it closes, if you want to. If you leave it empty, the phase closes when the next phase opens. On the last phase, it runs until the collection sells out.
Set the price, in the collection’s coin. Type 0 for a free mint.
Set max per wallet and max per transaction. Solana has no limit per transaction, so there the step asks for max per wallet only.
Set most this phase can sell, if you want a cap. 0 means no cap.
Add wallets to only these wallets to make it an allowlist phase. Leave it empty for a public phase.

Plan your phases before you sign. Prices, limits, lists and opening times are set here, and your dashboard keeps them as launched.

On Solana, every phase after the first must close, at most 30 days after it opens, and the step says so on the phase that breaks the rule. Each later phase is its own signature after the launch, so when more phases follow, a first phase set to open now opens 10 minutes after you sign.

Pick the coin it is bought in

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.

Under the phases, Bought in picks it. On Base the rows are USDC, the network’s dollar, and Another coin on Base, which asks for the coin’s address. On Solana they are SOL, USDC and Another coin on Solana. KURV names a pasted coin and how many places it counts to, so you can read your prices against it, and it has to have priced its fee in that coin before a collection can launch in it; the step says so when it has not. The coin stays for the life of the collection, and the Vault, your mint share and every royalty on KURV’s market are all in it. Collectors trade pieces with each other on KURV’s market in the collection’s own coin.

Add an allowlist

Paste wallet addresses into only these wallets, one per line.
To give a wallet its own limit, add a comma and a number after it.
Wallets with no number get the phase’s max per wallet.

0x70997970C51812dc3A010C7d01b50e0d17dc79C8,3

The list itself stays on our server. Only a small fingerprint of it goes on chain. When someone opens the mint page, it checks their wallet against the list, and Mint stays off until it has. If they are not on it, the page tells them before they press Mint.

Free mints

Set the price to 0 to launch a free mint. Free mints carry a service fee of $0.25 for each piece minted, charged in the collection’s coin. In another coin it is the same 25 cents at that coin’s price, set by KURV. The person minting pays it. Network costs are separate.

Free mint	Service fee
1 piece	$0.25
4 pieces	$1.00

Paid mints pay KURV’s 5% instead. See Fees for the full schedule, and read Risks and disclaimer before you launch.
