StonkSleeve is a StonkMe market written for Hyperliquid. It runs on HyperEVM and trades trade.xyz’s stock perps on HyperCore, with the same rules as the Solana program.
  1. The creator funds the take by sending USDC to the contract’s address on HyperCore. start moves it into the contract’s account on the stock dex. Only the contract can move it.
  2. One trader posts a stake, which stays on HyperEVM, and trades only the stocks the creator allowed, through trade: an immediate-or-cancel order within 1% of the mark price.
  3. Exposure is capped at the money traded.
  4. Anyone can close once the clock runs out or losses reach 80% of the stake, then settle a block later. The trader keeps 30% of any profit; losses come out of the stake first.
HyperCore actions land a block after the call that sends them, which is why closing and settling are two calls.
