One pull.
Any NFT in the pool.
A second kind of machine, where the inventory is not ours. Anyone can deposit an NFT and back it at a price of their choosing. That backing decides how often the machine picks it. Pull once, and whatever the machine chooses is yours.
This page exists because the mechanic is worth understanding before it ships, not because the machine is waiting behind a button. There is no contract yet, so there are no pool figures on this page — when there is one, every number here comes from it.
Four steps, all onchain.
Deposit
Add an ERC-721 to the pool and choose what it is backed at. The backing is yours — you set it, and you can take the NFT back out.
Backing sets the odds
Weight is one divided by backing, so an NFT backed cheaply is pulled more often than one backed high. Every card publishes its own weight.
Someone pulls
One pull, one NFT, chosen at random and weighted by backing. The price tracks the pool average plus a markup.
Settles onchain
Ownership transfers and the fee splits in the same transaction. Nothing is promised off-chain and settled later.
Cheaper backing means a likelier pull.
Weight is 1 ÷ backing, and an NFT's chance is its weight divided by the total. That is the whole formula. It means the pool self-balances: back something high and it is rarely pulled, back it low and it leaves quickly.
Three NFTs, backed as below. Redo the arithmetic yourself — that is the point of publishing the formula rather than a probability.
- Backed at 0.05
- 87.0%
- Backed at 0.50
- 8.7%
- Backed at 1.00
- 4.3%
Weights 20 : 2 : 1 — total 23.
The collections going in.
Four Arc collections are lined up for the first pool. Each links to its collection page so you can look at the art and the market yourself before anything is deposited.

No floor prices are printed here. They move constantly, so any figure on this page would be out of date by the time you read it — and it is the wrong number anyway: what a pull costs and how often an NFT is chosen follow the backing its depositor set, not what the collection trades at.
What is not settled yet.
Announcing a mechanic is not the same as having finished it. These are open, and saying so now is cheaper than walking a number back later.
- Pull price
- Pool average plus a markup — not yet fixed
- Fee split
- A share routes back to buyers — not yet fixed
- Withdrawals
- Depositors can take their own NFT back out
- Randomness
- Commit–reveal, as the token machines already use
- Contract
- Not written
The randomness is the one part already solved: Arc has no VRF, so Arcade publishes a hashed seed before a spin and reveals it after. The same mechanism carries over unchanged — you can read how it works on the fairness page.
The token machines are live.
Discovery is running now, pays eight different tokens, and every outcome settles onchain in about two seconds.
