The payout cap is known at execution, so each position’s worst case is reserved out of the pool before it opens and an order the pool cannot reserve is rejected. Collateral its owner can withdraw is never counted as cover. Payout cap

Every figure comes from one block, read every five seconds. A breach of either invariant pages the operator within a minute and stays on this chart; the testnet stage ends after fourteen days without one.
The index — option surfaces from Deribit and Derive — and all three funding legs — Binance, Hyperliquid and the native one from Lighter — are live venue reads, collected every 15 seconds. Orders settle in PrismPerpSettlement on Robinhood Chain Testnet: open interest, the vault and the solvency readings are read from the contracts, and the USDG in them is a test token worth nothing.
