OVERVIEW

How NYES works.

NYES runs short prediction markets on Solana memecoins. Each market asks one question: will this coin be above a price when the clock runs out? You buy YES or NO with USDC. All money goes into one shared pool. At zero, an onchain price decides the result and the winning side splits the pool.

CLOCKS

FEES

ORACLE

Pyth TWAP

There is no order book, no market maker and no human resolver. NYES does not take the other side of your position. Other traders do.

ACCESS

NYES is invite only right now. Anyone can read markets and check a coin. Opening a market needs an invite code. Public access opens in October at nyes.fun.

GETTING STARTED

Open your first market.

Connect a Solana wallet with USDC.

Any wallet that signs Solana transactions works. You need a small amount of SOL for network fees.

Paste the token’s contract address.

NYES reads the mint’s onchain pools and checks it against the listing rules. If it fails, you see why.

Pick a strike and a clock.

The strike defaults to the last oracle price. The clock is 90 seconds, 5 minutes or 15 minutes.

Sign one transaction.

The market goes live at the next slot and the clock starts. You earn 1% of the final pool whatever the result.

CORE CONCEPTS

Market lifecycle.

Every market passes through four states. It never returns to an earlier state.

OPEN
Buys accepted. Odds move with every fill.
LOCKED
Last 10 seconds. No new buys. TWAP window runs.
SETTLED
Result written onchain. Winners can claim.
CLOSED
Pool empty. The record stays readable forever.

Payouts are pushed to winning wallets automatically at settlement. If a push fails, for example because the account was closed, the amount stays claimable from the market account.

Pricing and payouts.

NYES is pari-mutuel. There is no fixed price per share. Your payout depends on how much is on each side when the market locks, not when you bought.

payout = stake × (pool − fees) ÷ winning side
fees   = pool × 1.5%

GROSS VS NET

The demo card shows an estimated total return after the 1.5% fee, including the selected stake. It includes the effect of adding that stake to the selected side. The worked example above uses a 100 USDC position already included in the YES pool. Final returns depend on the pool when buys lock.

Settlement.

Markets settle against a time-weighted average price from Pyth, not a single print. One large swap in the final second cannot decide a market.

WindowThe final 10 seconds of the clock. Buys lock when it starts.

RuleYES wins if the TWAP is strictly above the strike. Equal to the strike settles NO.

TriggerAnyone can call settle once the clock is at zero. A keeper does it in practice. The caller has no say in the result.

Dispute windowNone. The price is the result.

Listing rules.

A thin coin is cheap to push for ten seconds. NYES only lists coins where that costs more than any pool could pay. Checks run when a market is opened and again when it locks.

Onchain liquidity≥ $250,000
Pyth price feedrequired, live
Oracle confidence≤ 1% of price
Pool cap per market≤ 2% of liquidity

When a pool reaches its cap, the market stops taking buys. It still settles normally.

Fees.

1%

to the wallet that opened the market. Paid at settlement.

0.5%

to the protocol treasury. Paid at settlement.

0

fees on refunds. Voided markets return every stake in full.

Solana network fees are separate and paid by whoever signs.

When a market voids.

A void is a refund, not a result. Every stake goes back to the wallet it came from, with no fees taken.

One side is emptyNobody to pay and nobody to be paid by. Refunded.

Oracle goes staleNo fresh Pyth update for more than 3 seconds inside the window. Refunded.

Confidence too wideThe feed’s confidence interval crosses the strike at lock. Refunded.

Coin loses its listingLiquidity drops below the threshold before lock. Refunded.

Agents API.

PREVIEW · NOT LIVE

Agents will be able to open markets on a condition and read settled results per wallet. The endpoints below describe the planned shape. They can change before launch.

Risks and availability.

You can lose your whole stake. A 90-second market on a memecoin is close to a coin flip with a price attached.

Smart contracts and oracles can fail. Voids cover the oracle cases listed above. They do not cover bugs in the program itself.

Not available where binary pools are regulated as gambling. NYES is settlement infrastructure. You are not betting against the house.
