European Option Structure

A European option is a type of financial contract that can only be exercised on its expiration date. This is in contrast to American options, which can be exercised at any time before expiration.

Because they offer less flexibility to the holder, European options are generally simpler to price using models like Black-Scholes. In the cryptocurrency derivative market, most index-based options and many decentralized options protocols utilize a European structure to simplify settlement and margin requirements.

This structure eliminates the risk of early exercise for the option writer, making the margin engine more predictable. It also simplifies the management of the underlying collateral, as the position is fixed until the maturity date.

This predictability is highly beneficial for automated market makers and algorithmic trading strategies.
