Signed midpoint, Pyth breaker

A quorum of signers publishes the Hyperliquid best bid and offer every block. The contract checks signatures, age and distance from Pyth. Anything off and the market goes close-only.

02LiquidityPool.sol

Pool as counterparty, payout cap

Winners are paid from the qYUAN pool, losers fill it. One win is capped at a slice of pool equity; what the pool cannot pay today is issued as yIOU (YUAN IOU), a transferable claim redeemed 1:1 as the pool refills — or parked as margin for your next trade.

03Exchange.sol

Skew mid

The mark moves against the crowded side in proportion to net open interest over pool equity. Leverage and bust buffer adapt to realised volatility every minute.

Risk

This is a bookmaker at 10000x, settled in qYUAN.

A 0.005% move against a 10000x position busts it. The price feed is a signed oracle, not a precompile. The pool is unhedged and can run dry; yIOU is a claim, not cash. Margin is held in qYUAN, so you also carry qYUAN/USD exposure. Read the risk register before depositing anything you need.
