Why Is External Market Price Data Essential for Exercising a Crypto Option Contract?
External market price data is essential because an option's value and the decision to exercise are based on the price of the underlying asset relative to the strike price. The smart contract must know the current, accurate market price to determine if the option is in-the-money (ITM).
For example, a call option is exercised only if the current price is above the strike price. This price data, provided by an oracle, triggers the contract's automated settlement logic.
