Settlement
Two consensus prints. One formula. Refund if either print is missing.
The close is the last consensus price before 16:00 ET, or 13:00 ET on a half-day. The open is the first consensus price after 9:30 ET on the next session. Pools of the same asset on this chain have diverged by as much as 5.71% at the same moment. Settlement uses a liquidity-weighted consensus from pools with at least $50,000 of liquidity.
gap = (open - close) / close if gap > -k: premium kept else: pay min((-gap - k) * notional, cap)
Robinhood pauses the price feed around corporate actions. If close or open is unavailable, VIGIL voids and refunds. The model never supplies a number.
