Contract-definition risk comes first
If you misunderstand the underlying, expiry, target threshold, or side naming, everything after that is downstream error. Outcome markets reward precision and punish casual reading.

Topic cluster / Hyperliquid HIP-4 marketsThe main risks are contract misunderstanding, thin side liquidity, expiry compression, execution slippage, and overconfidence in a neat-looking yes-or-no market.
What to remember
If you misunderstand the underlying, expiry, target threshold, or side naming, everything after that is downstream error. Outcome markets reward precision and punish casual reading.
A yes-no contract can look simple while being hard to trade well. Hyperliquid's own support docs warn that trigger price and fill price can diverge, and that slippage becomes more painful in fast or illiquid conditions.
Perps let people hide from the calendar. HIP-4 does not. As expiry approaches, positioning, urgency, and interpretation can all tighten at once.
Hyperliquid's support docs note that actions can expire if they are not accepted by the L1 quickly enough. In short-horizon markets, a delay or duplicate attempt can matter more than it would in a slower thesis trade.
