Opyn v2 offers European, cash-settled options that auto-exercise upon expiry. Cash settlement means that option holders don’t have to provide the underlying asset in order to exercise. Rather, the options are settled in the collateral asset, and option holders receive the difference between the price of the underlying asset at expiry and the strike price from option sellers. Opyn options (oTokens) are ERC20s, so they can be trading on any decentralized exchange that follows the ERC20 standard. One of the main reasons investors trade options is to generate income. Similar to yield farming, options can be used to earn yield or generate an income in any market condition. Leverage allows traders to use less money to gain exposure to the movement of an asset's price. Options have similar market exposure to owning an asset, but require less money, allowing for more leverage and flexibility for your portfolio.
