4663
HOODS

4,663 pixel Hoods, 64 by 64, every trait dealt by a contract on Robinhood Chain. Eight rolls on chain (background, skin, hood colour, eyes, eyewear, mouth, hat, gear) and three more dealt from the same seed for the cut of the hood, hair and hair colour. The picture is rendered from those traits by our art server today and moves on chain once the collection has sold, layer for layer. Sold one at a time on a staccpad Number Go Up curve: the price only rises, and you can always sell a Hood back to the contract at the floor. Every trait is dealt from a sealed seed, so nobody sees a Hood before it is minted.

Coming soon

These are previews from the same renderer that will draw the real ones. Click one for its traits. A preview is not a token and may never appear in the collection: every real Hood is dealt from the sealed seed when it is minted.

Follow @4663hoods for the date. Nothing to claim, no allowlist: mint when it opens.

The promise: every Hood's traits are dealt from the sealed seed and never changed by us. Later, holders may be able to change their own Hood through actions they take, such as using items earned with other collections, and every such change will be a public transaction on the chain.

Unaudited contracts by staccpad, not by us. The curve keeps 90 percent of every purchase as the floor and the rest goes to the collection creator. Selling back pays the floor minus 6 percent. Buy then sell at once and you lose about 15 percent. Do not put in what you cannot lose.

How the traits are dealt

Each Hood's look is keccak256(salt, drand, id) fed into an on-chain renderer. The salt is ours and sealed: its hash is published before launch, the salt itself after the last Hood is sold. The drand value is a public random beacon from a round named before launch, published by a league of universities and companies, which nobody can predict. Neither we nor they could steer a single Hood, and anyone can check every deal.

The plan, in the open

Everything below is what we are doing and why, written before the launch so it can be held against us afterwards. Nothing here is a promise of price. It is a description of a machine.

The mint is a curve

4663 Hoods launches on staccpad's Number Go Up factory, the same contract family as denobodies. There is no batch mint and no allowlist. The contract sells Hoods one at a time, and every sale sets the next price a little higher, 0.05 percent per Hood. Ninety percent of every purchase goes into a vault held by the contract. The floor is that vault divided by the Hoods alive, and any holder can sell a Hood back to the contract at the floor minus 6 percent, any time, no buyer needed. Buy and sell straight back and you lose about 15 percent, by design.

Our 150

The launch mints 150 Hoods to us. We pay for them: 0.015 ETH goes into the vault with the launch, so the floor starts at the full base price from token one. The factory would let a creator seed for free, which would leave the first buyers standing on an empty vault. We do not do that, and the launch script we use refuses to.

How a Hood gets its look

Each Hood is dealt by a contract on Robinhood Chain from a 32-byte seed; the picture is rendered from that deal. The seed is keccak256(salt, drand, id): our sealed salt, whose hash is published before launch and which itself is published after the last Hood sells; the value of a public drand random beacon round named before launch, published by the League of Entropy and predictable by nobody; and the Hood's id. We could not pick a salt knowing the beacon, and the beacon could not know our salt. After sell-out anyone can recompute all 4,663 and compare.

Unminted ids return a blank placeholder, never a preview, so there is no waiting for a good one. The only way to learn what a Hood is, is to buy it.

Where the art lives

The renderer, with every trait table and every rectangle, is a contract on chain, verified so anyone can read it. The metadata is served from this site so marketplaces can read it, and it only ever calls that contract. If this site vanished, the art would still be on the chain and anyone could serve it again.

The tribute

The colour is #CCFF00. It is the background, the hood, the shades, the halo, the pin and the chart line. The Chart Only Up background is a line that only rises. This collection exists because stacc built the machine it runs on and the CCFF00 collection made the colour mean something.

What we will never do

  • Change a Hood's dealt traits. The salt and the beacon fix them, and the renderer is immutable.
  • Ask for an approval on your squares or your Hoods for any event we run.
  • Seed for free or mint outside the curve.
  • Promise a price. The curve is public; read it.

Unaudited contracts by staccpad run the curve. Do not put in what you cannot lose.

Potions

Three potions. Every #CCFF00 square gets one roll at a CCFF00 Potion, every Homecoming wizard one roll at a Wizard Potion, and every 4663 Hood one roll at a Mask Potion for Halloween. One roll per token id, ever, tracked here. A potion is yours: hold it, sell it on OpenSea, or drink it on a Hood you own to give that Hood a new piece. CCFF00 Potions draw from 512 pieces (background, skin, hood, cloak, wrap, halo, frame or badge in eight patterns and eight accents), Wizard Potions from 518 (robes, hats, gear, auras, sidekicks and backgrounds named the way the wizards name theirs, in fourteen tints), Mask Potions from 504 (eighteen masks, Ape to Feather, fourteen tints, plain or glowing eyes). Pieces are tokens too. A piece on a Hood moves with the Hood; strip it off and it lands in your wallet, tradeable on OpenSea like a potion, and any Hood can wear it.

Reading the contract…
How rolling stays safe. Rolling never asks for an approval and never moves your square, wizard or Hood. Roll straight from the wallet that holds them, or sign a ticket with that wallet and let any other wallet you name submit the roll and receive the potions. Either way the roller pays their own gas, about a cent. A ticket only says which ids and which wallet, expires in 24 hours, and each id can be rolled once, ever.
Why a buyer can trust the picture. To sell a Hood on OpenSea you first hand OpenSea the key to it. While a marketplace holds that key the Hood's wardrobe is frozen: you can add pieces, nothing can come off. To strip a piece you take the key back first, which also closes every open listing of that Hood. So if a Hood is buyable, what it is wearing is what comes with it.

How a roll works

A draw in two steps

  • Roll. One transaction marks your ids as rolled and books a draw against a block hash that does not exist yet: the hash of the last block of the next Ethereum block period, which the chain keeps for 256 periods, about 51 minutes. Nobody, including us, can know it when you roll.
  • Finish. About 24 seconds later the hash exists. This page prompts you to finish; the contract reads the hash, counts your wins and mints the potions. Anyone can finish anyone's draw, so if you leave, someone else may finish it for you. A draw not finished inside the window is forfeited: it pays nothing and the ids stay rolled. That rule is what stops a loser from waiting for a second draw.

Two doors, you pay your own cent either way

  • Direct. The wallet holding the ids rolls them, any number in one transaction, and finishes the same way. Potions land in that wallet.
  • Signed. The holding wallet signs a ticket: which ids, which wallet should receive, and a deadline. That is a signature, not a transaction: it moves nothing and approves nothing. The receiving wallet opens the ticket here, submits it and pays the gas. The contract checks the signature, checks the signer still owns every id, marks them rolled, and the potions go to the wallet you named.

Drinking

  • Drinking burns the potion and gives the Hood one piece it does not have. Which piece is fixed and public: the contract computes it from the Hood's id and how many it has drunk, over the pieces it still lacks. This page shows the next piece before you drink. A Hood with every piece of a kind is complete.
  • The latest piece per slot is worn. From the wardrobe you can show any attached piece, hide a slot, or strip a piece into your wallet as a token. A loose piece can be sold on OpenSea or worn by any Hood you own, which attaches it again. The picture on OpenSea and here follows within a minute.
  • Strip is refused while a marketplace holds the key to the Hood. Take the key back (one transaction, this page has the button), strip, then list again if you like.

For people who will not transact from the wallet that holds their squares, wizards or Hoods. Select ids on the left, type the wallet that should submit and receive, then sign. Nothing moves and nothing is approved.

Submit a ticket

Paste a ticket, or open a ticket link. The connected wallet submits the roll and pays the gas; the potions go to the wallet the ticket names.

FAQ

What is a Hood?

A 24 by 24 pixel character in the Punks and Nouns tradition, drawn by a contract on Robinhood Chain from eight traits: background, skin, hood, eyes, eyewear, mouth, hat and gear. 4,663 of them, ever.

How do I get one?

When the mint opens, connect a wallet on Robinhood Chain on the Mint tab and buy from the curve. No allowlist, nothing to claim, no waiting. The price you see is the price you pay, plus about a cent of gas.

What does "a curve that only goes up" mean?

Every Hood sold makes the next one 0.05 percent more expensive. Ninety percent of each purchase goes into a vault, and the floor is the vault divided by the Hoods alive. Sales into the vault keep a 6 percent exit fee, so the floor can only rise.

Can I sell a Hood back?

Yes, any time, straight to the contract, for the floor minus 6 percent. No buyer needed. You can also list it on OpenSea like any NFT.

What happens if I buy and sell right away?

You lose about 15 percent. That is written into the contract and is the cost of the floor existing at all.

Can I see what a Hood looks like before I buy it?

No. Unminted ids return a blank placeholder. The look is dealt the moment it is minted, from a sealed seed and a public random beacon. Nobody, including us, can know it earlier.

How do I know the team did not keep the good ones?

Our 150 are ids 0 to 149 and their traits come from the same rule as yours: a salt whose hash was published before launch, plus a drand beacon round named before launch and fixed after. We could not have chosen a salt knowing the beacon. After sell-out the salt is published and anyone can recompute every Hood.

Is the art really on chain?

The renderer contract holds every trait and every rectangle and draws the SVG on demand. This site serves the metadata so OpenSea and wallets can read it, and only ever calls that contract. Verified source, readable by anyone.

Will it be on OpenSea?

Yes. OpenSea indexes Robinhood Chain on its own; the collection appears once it exists, with traits and rarity.

What are potions?

Items you win by rolling, one roll per token id. Every #CCFF00 square rolls for a CCFF00 Potion, every Homecoming wizard for a Wizard Potion, every 4663 Hood for a Halloween Mask Potion. A potion is a token you hold, sell, or drink on a Hood you own to give it a new piece: 512 CCFF00 pieces, 518 wizard pieces or 504 masks, never a duplicate on the same Hood. The Potions tab has the odds and the whole flow.

Can I sell a piece?

Yes. Strip it off the Hood and it becomes a token in your wallet, tradeable on OpenSea like a potion. Any Hood you own can wear it, which attaches it to that Hood. Strip is refused while a marketplace holds the key to the Hood: take the key back first (the wardrobe has the button), which also closes that Hood's open listings. That rule is why a buyer can trust the picture: a listed Hood can only gain pieces.

Why does a roll take two transactions?

The first books the draw against a block hash that does not exist yet, so nobody can know the result in advance, not even us. About 24 seconds later the second reads that hash and mints your potions. Anyone can send the second, and the page prompts you as soon as it is possible. If nobody finishes a draw inside about 51 minutes it is forfeited and pays nothing; without that rule a loser could wait out the window and draw again.

Do I have to roll from the wallet that holds my squares or wizards?

No. Sign a ticket with that wallet, which moves nothing and approves nothing, and let any other wallet you name submit the roll and receive the potions. The wallet that submits pays the gas, about a cent. Tickets expire after 24 hours and each id can only ever roll once.

Which piece will my Hood get?

It is fixed and public before you drink: the contract computes it from the Hood's id and how many potions it has drunk, over the pieces it still lacks. The Potions tab shows the next piece for any Hood. Attached pieces stay with the Hood if it is sold, and the owner chooses which attached piece to show in each slot.

Does anything ever ask for approvals on my squares or Hoods?

No, and it never will. Nothing we build can move your tokens.

Is this audited?

No. The curve contracts are staccpad's and are unaudited, as their site says. Our renderer is verified and tested against the reference art on every possible combination, but tested is not audited. Do not put in what you cannot lose.

What is #CCFF00?

A colour, a collection on Robinhood Chain, and the reason this exists. Every Hood carries it somewhere.

When?

Soon. Follow @4663hoods. The commitment hash and the beacon round will be posted there before the first mint.
