## 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.

## Glossary

### [Covered Calls](https://term.greeks.live/area/covered-calls/)

Asset ⎊ Covered calls represent a strategy wherein an investor, holding an underlying cryptocurrency asset, grants another party the right, but not the obligation, to purchase the asset at a predetermined price—the strike price—on or before a specified date.

### [Smart Contract Security Audits](https://term.greeks.live/area/smart-contract-security-audits/)

Methodology ⎊ Formal verification and manual code review serve as the primary mechanisms to identify logical flaws, reentrancy vectors, and integer overflow risks within immutable codebases.

### [Volatility Analysis](https://term.greeks.live/area/volatility-analysis/)

Analysis ⎊ Volatility analysis, within cryptocurrency, options, and derivatives, centers on quantifying the degree of price fluctuation over a defined period, serving as a critical input for risk management and option pricing models.

### [Black-Scholes Model](https://term.greeks.live/area/black-scholes-model/)

Algorithm ⎊ The Black-Scholes Model represents a foundational analytical framework for pricing European-style options, initially developed for equities but adapted for cryptocurrency derivatives through modifications addressing unique market characteristics.

### [Strike Price](https://term.greeks.live/area/strike-price/)

Price ⎊ The strike price, within cryptocurrency options, represents a predetermined price at which the underlying asset can be bought or sold.

### [Incentive Structures](https://term.greeks.live/area/incentive-structures/)

Action ⎊ ⎊ Incentive structures within cryptocurrency, options trading, and financial derivatives fundamentally alter participant behavior, driving decisions related to market making, hedging, and speculative positioning.

### [Protective Puts](https://term.greeks.live/area/protective-puts/)

Application ⎊ Protective puts, within cryptocurrency derivatives, represent a risk management strategy employing options contracts to establish a price floor on an underlying digital asset holding.

### [Smart Contracts](https://term.greeks.live/area/smart-contracts/)

Contract ⎊ Self-executing agreements encoded on a blockchain, smart contracts automate the performance of obligations when predefined conditions are met, eliminating the need for intermediaries in cryptocurrency, options trading, and financial derivatives.

### [Liquidity Provision](https://term.greeks.live/area/liquidity-provision/)

Mechanism ⎊ Liquidity provision functions as the foundational process where market participants, often termed liquidity providers, commit capital to decentralized pools or order books to facilitate seamless trade execution.

### [Historical Volatility](https://term.greeks.live/area/historical-volatility/)

Calculation ⎊ Historical volatility, within cryptocurrency and derivatives markets, represents a statistical measure of price fluctuations over a specified past period, typically expressed as an annualized standard deviation.
