OPYN

Opyn allows users to earn a premium or take views on assets by trading options on ETH and ERC20s. Opyn v2 offers European, cash-settled options that auto-exercise upon expiry. Opyn options (oTokens) are ERC20s, so they can be trading on any decentralized exchange that follows the ERC20 standard. Opyn v1 laid the foundation for DeFi options as the first live ERC20 options protocol. For the first time, anyone could create, buy, and sell options on any ERC20 token. Opyn v1 will remain live on the Ethereum network, providing a venue for American, physically settled options. We will continue to launch ERC20 options on Opyn v1.
