## European Vs American Options

The primary difference between European and American options lies in when they can be exercised. European options can only be exercised at the exact moment of expiration.

American options, by contrast, can be exercised at any time up to and including the expiration date. This flexibility makes American options potentially more valuable but also more complex to price.

In the context of digital assets, most on-chain options protocols have moved toward European-style structures to simplify settlement and avoid early exercise complications. American options are more common in traditional equity markets.

Understanding the exercise style is vital for determining the correct pricing model and evaluating the strategic utility of the derivative. The choice between them impacts how traders manage their positions and potential early assignment risk.
