How does Opyn v2 work?
Opyn offers cash-settled European options like those in traditional finance. European options are only executable at the expiry but they can be sold prior.
Opyn v2 has an auto-execute that executes in-the-money options automatically. Cash-settled options don’t require any underlying to change hands at execution. The settlement results in a cash payment. Chainlink oracle calculates the execution price.
oTokens represent options contracts in Opyn. Anyone can create unique call or put options for the whitelisted assets. Once an option is created, it’s represented by an oToken contract, and now anyone can buy and trade this option. Sold oTokens have to be fully collateralized.
oTokens on the Opyn v2 interface trade on 0x and it’s possible to trade them on any ERC-20 compatible exchange. The options are priced according to supply and demand.
Opyn recently announced limit orders where you can post offers to sell or buy options for a custom price. If the order gets filled the counterparty pays the gas fees.
What can you do with Opyn?
Spreads
In addition to pure short and long exposure, you can create spreads in Opyn v2. Spreads are used to trade different strategies. The maximum loss structure of a spread can be used as collateral to boost capital efficiency.
For a guide to some of the different strategies, you can trade on Opyn check out this article.

Insurance
Protective putts are a comprehensive hedge against any protocol malfunctions and price decrease.
Companies and individuals using ETH in their operations in the future can hedge against ETH price increase with call options.
Flash minting
With flash mints, developers can mint oTokens without the collateral requirement. The oTokens have to be burned (redeemed) in the same transaction. This can be used for arbitrage between exchanges and collateralizing options with the proceeds from premiums.
Operators
Operators allow users to grant rights to their assets to smart contracts. These smart contracts can be used to roll over contracts or act as portfolio managers. Developers can also build a variety of applications using operators.
