What am I betting on?
Whether a name finishes over or under a strike price at expiry. Nothing in between, no scores, no partial outcomes.
What happens if I'm right?
You collect the multiple shown on the button. $25 at 2.10x returns $52.50.
What happens if I'm wrong?
The contract settles at zero and you lose the stake. That is the whole trade.
Where do the odds come from?
A cash-or-nothing digital priced with Black-Scholes off spot, strike, volatility and time left. A coin-flip strike prices near 1.94x. Move the strike away from spot and the odds lengthen, exactly as they should.
What is the house edge?
3%, taken as juice. It is already inside every number you see — nothing is added at settlement.
When do contracts settle?
Hourly contracts settle on the hour. Daily ones settle at the 4pm close. Crypto settles on the same clock but never closes.
Can I sell or close early?
No. Every contract runs to expiry. There are no exits, so the countdown is a settlement timer rather than a sell window.
Can I bet the same market twice?
Yes. Bets stack on the same side and each one is its own ticket at the odds you got when you placed it.
What do I bet with?
USDG, the native stablecoin of Robinhood Chain. Bridge USDC in from Base, Arbitrum, Optimism or Ethereum and it arrives as USDG.
Do I need to sign every bet?
Yes. Bets fire straight from your wallet, so nothing moves without a signature from you.
What is Earn?
A pool that takes the other side of every bet. Deposit and you are the house: you earn the vig plus whatever the book takes off players, and you lose when players win. Your position can go down.
Can I withdraw from Earn whenever?
Only capital that is not backing an open contract. The rest frees up as those contracts settle.
What are points for?
A future token allocation. Terms are not final, and we would rather say that than imply otherwise.
Is this live?
It is a prototype. Prices are simulated and nothing settles on-chain yet. The pricing maths is real.
