Freezing trading? If you freeze trading below, this date is what can make the freeze permanent. Minting stops when your drop closes, so a drop that closes before the last piece is minted stays frozen - and only a transaction from your own wallet can open it again.

Trading freeze - optional

Trading freeze. Nothing can be traded until the drop mints out - including by you, and it costs your holders gas on every trade for as long as it stays attached. Freeze trading until the collection mints out. While it is on, no piece from your collection can be traded - not sold, not sent, not moved. Minting is never blocked, and the freeze lifts itself the moment the last piece is minted: that needs no transaction from you and costs you nothing.

Freezing trading until a drop mints out is set up per chain.

i Six things a trading freeze cannot fix. Read them before you tick that box.
1. There is no exemption for you. While it is frozen you cannot move a piece either - not to another wallet of your own, not to a giveaway winner, not to a collaborator.
2. Your closing date can make it permanent. Minting stops when the drop closes, so if your sale window ends before the last piece is minted, the freeze stays on until you lift it from your own wallet.
3. Renouncing ownership can make it permanent for everyone. If you give up ownership of the collection and it can no longer mint out, nobody can ever lift it - not you, not us, not the people holding your pieces.
4. Lifting is not permanent by itself. Raising the supply later re-freezes a collection that is already trading. Only “Lift the freeze” below makes it permanent.
5. People can still sign listings. A listing can exist on OpenSea for a piece that cannot be traded, and the sale fails for the buyer at the moment they pay.
6. It costs your holders gas. About 9,161 extra gas on every secondary trade for as long as the freeze contract stays attached - including after your drop has sold out and the freeze has already lifted itself.

One extra wallet prompt at launch, about 50,275 gas.

Connect the wallet your sales should arrive in

A wallet is your account for this collection - like a bank account that only you hold the key to. Every sale is paid straight into it. It is also how you approve the launch, so nobody else can launch or change your collection.

Paid to youBuyers pay your wallet. Mintor never holds it.
Only you move itConnecting only shows us your public address.
Free to connectYou approve each cost yourself, at launch.

No wallet?

Get a wallet app. MetaMask is the most widely used and is free - add it to your browser from metamask.io. On a phone, install the app and open this page inside it.
Create your wallet. It gives you a secret recovery phrase. Write it on paper and never share it - anyone who has it controls your money, and nobody can reset it for you.
Come back to this tab and press “Connect my wallet”. Everything you have filled in is saved here.
Before you launch, the wallet needs a small amount of ETH to pay the network's processing fee. You will see the exact amount before you approve anything.

Resale royalty

Your share each time one is resold - optional

Royalty paid to

The OpenSea step

⚠ Whichever you pick below, OpenSea needs this percentage typed into their dashboard too. OpenSea does not read the royalty off the contract for a drop launched here - it is a SeaDrop collection, and that is measured, not assumed. Once your drop is live and OpenSea has indexed it, open OpenSea Studio with the wallet that owns the collection, find your collection's creator earnings and enter the same number. It takes about a minute, and until you do it OpenSea pays you nothing on a sale. Every drop you launch needs it again. Or let this page do it for you once your drop is live: “Enforced royalties” below has a Set it on OpenSea too button that does exactly this from two signatures, with no gas.

How your royalty is enforced

Enforced royalties. Your collection can be traded only on marketplaces that pay the creator - it decides WHERE, not whether, and OpenSea still needs the percentage typed into their dashboard.

How your royalty is enforced

Optional - any marketplace can trade it. Marketplaces that honour royalties pay you; the ones that do not, do not. This is how almost every collection works, and it is exactly what this page has always launched. Enforced - it can only be traded where you are paid. Your collection can only be traded on marketplaces that pay the creator, and - once you have switched it on in OpenSea Studio - OpenSea will not let a seller list it without the fee. 🚨 Until you finish that step in OpenSea Studio, a piece cannot be BOUGHT on OpenSea at all. We listed one and the purchase failed.

How a royalty is enforced is set up per chain.

i Eight things enforced royalties are, and are not. Read them before you pick that one.
1. It decides WHERE, not whether. Your collection can only be traded on marketplaces that pay the creator, and - once you have switched it on in OpenSea Studio - OpenSea will not let a seller list it without the fee.
2. It does not stop a private transfer. Two people can still agree a price somewhere else and move a piece between themselves for nothing. That was measured, not assumed, and nothing on chain can prevent it.
3. Holders can still move their own tokens between their own wallets, and still send one as a gift. Enforcement never touches that.
4. You can switch it off later, and switching it off is one transaction from your own wallet, on “Enforced royalties” below. Nothing here is permanent.
5. It is not the percentage. What you are paid is the royalty above; this only decides where your collection may be traded. Enforcing a 0% royalty would restrict every marketplace and pay you nothing, so this page will not launch that pair.
6. It cannot be combined with the trading freeze. A collection has one transfer-validator slot: the sellout freeze uses it while your drop is minting, enforced royalties use it afterwards. So the two are sequential, not simultaneous - launch frozen if you want the freeze, and once your drop mints out swap to enforced royalties from “Enforced royalties” below. That swap is one transaction you send yourself; it does not happen on its own.
7. OpenSea needs two things from you afterwards, and nothing on this page can do either. Enforcing on chain only makes your collection eligible - that is OpenSea's own word for it. Once your drop is live and OpenSea has indexed it, open OpenSea Studio with the wallet that owns the collection and go to its creator earnings. There, first enter your percentage: that is what makes the fee exist at all, and until you do it OpenSea pays you nothing on a sale, whatever your contract says, because it does not read the percentage off the contract for a SeaDrop drop like this one. Then press Enforce earnings - a signature, not a transaction - which is what makes paying it mandatory instead of the seller's choice. The first step is worth doing even if the second is unavailable to you. Every drop you launch needs both again.
8. Do both together, or neither - because we measured what happens in between. With enforcement attached on chain and the Studio step not done, OpenSea still takes a listing and still shows a price, and the purchase itself fails. Enforcement tells the chain to refuse every marketplace that does not pay you, and OpenSea's ordinary buy path is one of those until OpenSea knows your collection is enforced. That is not a guess: we put a real listing on a real enforced collection and the buy reverted. Finishing the Studio step is what is meant to move OpenSea onto a route your collection allows - that is how OpenSea documents it, and we have not been able to confirm the fixed state ourselves. So if you pick this: do the Studio step as soon as your drop is indexed, and check that a piece can actually be bought before you tell anybody it is for sale. If you are not ready to do that, pick optional.

One extra wallet prompt at launch (about 50,191 gas); your holders pay about 6,207 extra gas on every secondary trade while it stays attached.

What do the royalties do?

Holder rewards. Pay a share of the resale royalty back to the people holding your pieces, claimed by them from their own wallet.

Which stock

Royalties are swapped into this stock and paid to holders.

Mint money and royalties go to your payout wallet.

Your wallet needs your approvalOpen your wallet and confirm to continue. Nothing happens until you do.

$1 on top of your price, paid by the minter. The fee is stored as a percentage of the mint price, fixed when the drop is configured: the contract refuses any payment that is not exactly the mint price, so our $1 is part of the price rather than added at checkout. It is worth $1.00 at today's ETH price and will drift with ETH from then on; if that ever matters you can update the drop yourself. Only mints made through this site pay Mintor - a buyer who mints on opensea.io pays OpenSea the same share instead, and your take is identical either way.

What a resale pays you

The collection

i What enforcing does, and what it does not. Your collection can only be traded on marketplaces that pay the creator and, once you have switched it on in OpenSea Studio, OpenSea will not let a seller list it without the fee. It does not stop two people arranging a private transfer between themselves for nothing, and holders can still move their own tokens between their own wallets. It collects nothing by itself - what you are paid is the royalty percentage set on your collection, and enforcing a collection that pays 0% restricts where it can be traded without paying you anything. Switching it off again is one transaction from this card. Only the wallet that owns the collection can do either, and that is checked against the chain. And OpenSea needs one more step from you that is not on this page - see below.

⚠ Two steps OpenSea will not let us do for you. Enforcing on chain only makes a collection eligible - OpenSea's own word. Open OpenSea Studio with the wallet that owns the collection and go to its creator earnings: first enter the percentage, then press Enforce earnings, which asks for a signature rather than a transaction and is what makes paying it mandatory instead of the seller's choice. If this is a drop launched here the first step is the one that decides whether you are paid at all - it is a SeaDrop collection, OpenSea does not read the percentage off the contract for those, and until it is typed in Studio OpenSea pays you nothing on a sale. Each collection needs this once. You do not have to do that first step by hand: the Set it on OpenSea too button below does it from two signatures and no gas. The second step, Enforce earnings, is OpenSea's own and can only be done there.

🚨 And while a collection is enforcing on chain but not yet switched on in Studio, it cannot be BOUGHT on OpenSea at all. It still gets listed and still shows a price, and the purchase fails - we put a real listing on a real enforced collection and the buy reverted. If that is where yours is, either finish in Studio now or press “Make it optional” below, which is one transaction and puts it back on sale everywhere.

What it pays

Paid to

Load a collection above to see what it pays today.

⚠ Read this before you press it - you are signing something, not sending it. You will be asked to sign two messages, and neither is a transaction: no gas, and nothing moves. The first is ours and names this collection, the percentage and the wallet being paid (and the switch to ETH, if ticked) - read it, because it is the one that authorises the change. The second is OpenSea's own sign-in, whose text says “Click to sign in and accept the OpenSea Terms of Service and Privacy Policy”, so signing it accepts those terms. 🚨 What that sign-in creates is a key that can edit the settings of every collection this wallet owns on OpenSea - not just this one. Mintor asks OpenSea for the narrowest kind there is, uses it for this single write, and then deletes it before answering you; if OpenSea does not confirm the deletion, this page says so and tells you where to remove it yourself. It is never written to disk. Only the wallet that owns the collection can do this, and your collection has to exist on OpenSea already, which takes a few minutes after a launch.

Sell in ETH on OpenSea (recommended) - listings in ETH, offers in WETH, so your royalties arrive in ETH instead of USDG. Same sign-in, no extra signature.

Running the sale

The collection

⚠ This replaces the whole sale, not just the box you edit. The contract keeps the price, the opening time, the closing time and the per-wallet limit as one record and overwrites all of it at once - so every field below is sent every time. A box left blank is not “leave it alone”; the values already filled in are what the collection says today, and they are what gets written back unless you change them. A per-wallet limit of 0 stops every mint in the collection, for everyone, until you send another transaction - so it is refused here. Re-pricing re-works our $1 at today's ETH rate. The mint price a buyer pays is your price plus our dollar, because the contract refuses any payment that is not exactly the mint price - there is nowhere else to put it. The split is shown below before you sign. Anyone who already minted keeps what they paid. This changes the sale from now on and nothing about a mint that has already happened. This is the PUBLIC sale only. A whitelist stage carries its own price and its own window inside the proofs your listed wallets already hold, and no transaction from this card can reach them - not even “End it now”. To stop a whitelist stage as well, use Change a whitelist above and remove it entirely. Only the wallet that owns the collection can do this, and that is checked against the chain.

Ownership, splits and artwork

The collection

i How this works, and what it cannot do. You describe the split; this page works out the address it will live at and you point your collection’s royalty there. Royalties then arrive on their own and each person withdraws their own share whenever they like - nobody has to trust anybody to pass money on, and no payment can fail on the way in. The shares are fixed the moment it is deployed. Nobody can change them afterwards - not the other recipients, not us, not you - so check them before you use the address. Each person can move their own share to a new wallet, signing from the old one - the box at the bottom of this card does it, and it works while you can still sign from the old wallet, not afterwards. It also handles tokens, not just ETH, which matters here because OpenSea prices this chain’s sales in USDG. Every currency gets its own line and its own button below, because they are separate piles of money and claiming one does not touch the other. Anybody can press those buttons. A payout pays each recipient their own share and never the person who pressed it - so a stranger triggering it is doing you a favour, and somebody whose wallet cannot send transactions can still be paid by someone who can.

The split

Type the wallets and numbers exactly as you set them up. 70 and 30 pays the same percentages as 7 and 3, but they are two different addresses: the address is worked out from the numbers themselves, so a rescaled split points somewhere your royalties have never been and shows up empty. They do not have to add up to 100.

i What the person who publishes snapshots can and cannot do. Royalties collect in the contract on their own. To pay holders, whoever owns it publishes a snapshot - a record of who held what - and each holder then claims their own share. They cannot make the holders' pool bigger. The share was fixed when the collection launched and the contract refuses any snapshot that tries to pay out more than it, so the team's side and the holders' side cannot reach each other. What they could do is aim the pool at the wrong wallets. The snapshot is worked out from public information - who holds which token, right now - so anyone can check it, and this page shows you the full list before anything is published. That is a reason to look, not a promise you will not have to. Nothing expires. Ignore ten snapshots and claim once; you are paid exactly the same. 🚨 A snapshot covers ONE currency. Royalties on this chain arrive as USDG, not ETH, because that is what OpenSea prices sales in - and the contract keeps a separate snapshot for each. Publishing an ETH snapshot pays nobody their USDG, and a holder claiming the wrong one is refused by the chain. Pick the currency first, and publish once per currency you have earned in.

Which currency

Royalties arrive in whichever currency the sale was priced in.

Make the art

Layers in, a collection out - in this browser. Generative art. Bring a folder of trait layers and this browser composites the whole collection and its metadata - the art never leaves this tab.

i Your art never leaves this browser. The layers are read off your disk, composited by this tab, and - if you choose to pin them - sent straight from here to your own pinning account. There is no Mintor server anywhere in that path and there is nowhere for one to be. Your pinning key is typed here, used here, and stored nowhere: not in this page's draft, not in this browser's storage, never in a URL. A HashLips config.js is read, never run. It is a program, and running one in a tab with your wallet connected would hand whoever wrote it the run of that tab - so we scan it as text and ask you to type anything we cannot read that way.

1 · Bring your layers

One folder per layer, one image per trait, named Trait#weight.png - Blue#50.png. No # means a weight of 1. Pick the folder that holds the layer folders, or a zip of it.

▤ Your layers folderthe one that holds Background, Body, Eyes… - one folder per layer inside it. This is the only picker that takes a folder.

Pick the folder above your layers, not one layer. Picking a single layer folder gives a collection with one layer in it.

◈ …or a .zip of that same folderthe same shape, zipped - one folder per layer inside it ⚙ …and optionally a configa .json, or a HashLips config.js - read as text, never run

Nothing picked yet.

Layer order - bottom of the stack first

One layer name per line. Leave it empty and the layers are stacked alphabetically, which is a guess - z-order is the one thing a folder cannot tell us, and guessing it wrong paints the background over the face.

2 · Rules

Optional. Rules are applied while the collection is drawn, never by filtering it afterwards - filtering leaves holes you then refill, which is how a rare trait quietly doubles in frequency.

Never together

One pair per line: Layer/Trait + Layer/Trait. Symmetric - no token will ever hold both.

Always together

One pair per line: Layer/Trait -> Layer/Trait. Directional - every Robot body gets Laser eyes, but Laser eyes may appear on their own.

One-of-ones

One per line: a name, =, then a trait in every layer. It appears exactly once. “The rest at random” is not a one-of-one - that is a rule.

3 · Does it fit?

The supply comes from Total supply in “The sale” - the wizard owns that number and the generator reads it, so there is only ever one.

4 · Generate

Seed

The same seed, the same layers and the same names make the same collection again. It is the only way back if you lose the files.

Output size

Square or not, your choice. Bigger costs memory, not just time - the check below refuses a size this browser cannot hold and names one it can.

Token name prefix

Token #1 is named “Cabinet #1”. Blank uses your collection name.

Description

The same sentence on every token, and on the collection.

Cover picture - the one everybody sees before the reveal

Optional, and it must be pinned on its own. Pick a file below and we pin it as a one-file directory with a CID of its own, or paste one you already have.

◍ Pick the cover picturePNG, JPEG, GIF or WebP - pinned on its own, with a CID of its own

5 · Publish

Two ways, and they are the same standing. Pin with your own account, or download the archive and pin it wherever you like.

Where the files go

Pay in

A one-time payment from your wallet to the platform fee wallet. The stable is the same one the Smart NFT panel reads; the price is the same either way.

Your pinning key

Hold the metadata back until I reveal. The pictures are pinned now and the per-token documents stay in this tab - there is nothing on IPFS for a sniper to find. The strongest reveal there is, and the one that loses everything if you close this tab without downloading the archive. Launch behind the pre-reveal placeholder. The drop opens on the single placeholder document this page pinned: every token shows it, and the art stays unreadable until you send “Reveal the artwork” below. This is the one base URI without a trailing slash we will launch, and only because you are naming it here - until you reveal, every token in the collection serves that same document, which is the whole point of it and is also permanent if you never reveal. I am launching behind my own placeholder folder. Leave both of these unticked and the drop launches on your metadata folder - the real art is visible from the first block. Tick this one and step 3 stays yours: pin a placeholder folder (identical documents named 1, 2, 3 … one per token) and paste it there with its trailing slash; the metadata folder then goes to “Reveal the artwork” below, later. A slashless folder of your own is still refused - the server cannot tell one from a typo, and the only slashless URI it will take is the pre-reveal document above.

The faces on this page are clay heads by 0xClayFactory, the collection that designed this launchpad. Every one is a real piece, sculpted by hand and photographed, not drawn by us.
