Getting started
What you need
- A
Solana wallet such as 
Phantom. 
USDC on Solana for margin, and a little SOL for network fees.
First position
- Open the app. It shows the live index, the next expiries and the order book of each weekly series.
- Pick a series. Each one settles on a Friday at 16:00 UTC.
- Choose a side. Long gains when the premium settles higher than your price; short gains when it settles lower.
- Enter a price inside the band and a number of contracts. The app shows the margin you lock and the fee before you sign.
- Sign. Your margin moves into the market's vault.
Orders and positions live on Solana mainnet. Each open order and each position holds a small SOL deposit for its account, about 0.001 SOL, which comes back to you when it closes.
How much you lock
| Side | Margin per contract at price P |
|---|---|
| Long | (P − floor) × $10 |
| Short | (cap − P) × $10 |
At P = +0.50 pp on the −5 to +5 band, a long locks $55.00 and a short locks $45.00, each plus a $0.10 fee.
After expiry
- A reporter posts the settlement value with a bond.
- Six hours later, if nobody disputes, anyone can settle the market.
claimpays your USDC account. Anyone can run it for you, and it pays only you.
Leaving early
Take the opposite side in the same series. Your result locks in at that price, because a matched long and short are worth exactly the band at any settlement, and the margin of both legs comes back to you when the series settles.
