Markets on Robinhood Chain
Combine your calls.
A Combo joins two to five outcomes into one position with one payout.
Try a Combo,
see the math.
Slide each leg's chance and watch the payout move. Example numbers only.
One balance
for everything.
Singles and Combos share one stablecoin Cash balance on the chain. Auralis moves funds between the markets and the vault for you. What you win comes back to Cash.
Every market names
its referee.
Before you trade, the market shows exactly where its result will come from.
A Chainlink feed on Robinhood Chain. Anyone can trigger settlement.
The published final result. Postponed or abandoned games are voided.
A central bank statement or a statistics office release, named on the market.
A named public source, written into the market's rules before trading opens.
If a source can't give a clear answer, the market is voided and stakes return. A void leg is removed from a Combo, which is repriced on the remaining legs at the odds you accepted. With fewer than two legs left, the stake is refunded.
Why a maker market?
The same idea as a parlay, priced in the open.
| What matters | One house sets the price | Auralis |
|---|---|---|
| Combo price | A single quote, take it or leave it | Makers compete and the best payout is shown |
| Collateral | Each position locks its own full payout | Counted across a maker's whole book |
| Settlement | The operator calls the result | A named source, on-chain, anyone can trigger |
| Cost | The margin may not be visible | Shown as the To win amount before you accept |
| Early exit | The operator's offer, if any | Ask several makers, accept only if you like it |
A comparison with a generic single-operator model, not any named product. Design concept.
Know the risks
before you trade.
Plain language, up front.
A Combo pays only if every leg wins. Your maximum loss is the stake you placed, never more.
This is a design concept. Nothing is deployed and nothing has been audited. A real launch would need independent audits and a public report.
Settlement waits for a feed round recorded after the market closes. If a source can't answer clearly, the market is voided and stakes return.
Stock Tokens are restricted in several regions, including the US, Canada and the UK. Check the rules where you live.
Example data only. Nothing here is financial advice.
Under the hood
Built on Robinhood
Chain, end to end.
Markets, vault and price feeds all live on Robinhood Chain, Robinhood’s own Ethereum layer 2 for tokenized stocks and real-world assets.
Every market and order book is a contract on Robinhood Chain. Single trades go straight to it.
Stock and crypto markets resolve from Chainlink Data Feeds, read on-chain.
Holds each Combo's stake and settles permissionlessly once every leg has resolved.
For makers
Makers compete
for every Combo.
No single house maker sets your price. Any trader can plug in and quote, and the best payout gets displayed. Maker collateral covers exposure across your whole portfolio rather than an individual position.

Fully backed.
Less locked.
Two Combos that can't both win shouldn't each lock their full payout. Count what a maker's whole book can lose at once, and the same money backs more Combos, so makers can quote more and pay better.
For builders
Build your project
on Robinhood Chain.
From Stock Token to settled Combo. Deploy with the Ethereum tools you already use, read prices from Chainlink, and plug into the same makers and vault that power Auralis.
Questions
What is Auralis?
A prediction market app on Robinhood Chain. You trade one outcome at a time, or combine two to five outcomes into a Combo with one payout.
Why Robinhood Chain?
It is Robinhood’s own Ethereum layer 2, designed for tokenized real-world assets and markets that run around the clock. It works with standard Ethereum tools and has Chainlink price feeds, so a stock or crypto price can settle a market directly on-chain.
Can I build on it?
Yes. Robinhood Chain is permissionless, so anyone can deploy contracts. Start from the official docs, then read a Chainlink feed in your own contract.
What is a Combo?
A Combo joins two to five outcomes into one position, like a parlay. It pays in full only if every leg wins. You see the payout before you place it.
Who sets a Combo's price?
Market makers. Your Combo goes out as a request for quotes, makers answer with payouts, and you take the best one. The To win amount is what you receive after known fees.
Where is my money?
In one stablecoin Cash balance on the chain. Single trades happen in the market contracts. When you place a Combo, your stake and the maker's money lock in the vault until the results are in.
Who decides the results?
Price markets resolve from Chainlink price feeds on Robinhood Chain, and the vault reads the feed directly. Settlement is permissionless, so anyone can trigger it.
Can I cash out a Combo early?
You can ask makers to buy your whole Combo before it settles. If a maker makes an offer, you choose whether to take it. An offer isn't guaranteed.
What does it cost?
Every trade shows its cost before you place it. See the Fees page for a worked example.
Who decides results that aren't prices?
Every market names its resolution source before you trade: an on-chain price feed for stocks and crypto, and a named public source for the rest, such as an official league result or an official statistics release. If the source can't give a clear answer, the market is voided and stakes return.
What if one leg of a Combo is cancelled?
The void leg is removed. The Combo is repriced on the remaining legs at the odds you accepted and pays on those. If fewer than two legs remain, your stake is refunded.
What if a price feed is late or stale?
Settlement only accepts a feed round recorded at or after the market's close. If there isn't one yet, the leg waits instead of settling on an old price.
What if a maker can't pay?
The maker's side is locked in the vault when your Combo is placed, so the payout is fully backed before the Combo starts. You don't rely on a maker's promise later.
Can I lose more than my stake?
No. Your maximum loss is the stake you placed. A Combo can lose all of it if any leg loses.
Is it available where I live?
Stock Tokens are not offered in some regions, including the US, Canada, UK, Switzerland, UAE and sanctioned regions, according to a launch report. Check eligibility. This site is a design concept with example data.
