**About Opyn**

Opyn is a capital efficient DeFi options protocol that allows users to buy, sell, and create options on ERC20s. For developers, Opyn is the most flexible and secure options protocol in DeFi. The name Opyn comes from our mission to empower people through a more inclusive, fair, open, financial system.

Opyn was created in 2019 by three friends obsessed with crypto and DeFi. Since then, we’ve shipped two versions and the team has grown to thirteen across six continents. Opyn was the first protocol to bring options, spreads, and partial collateralization to DeFi. What started as a few users has turned into a community that has collectively traded more than $1.3 billion of options across 27,000+ trades and we're just getting started. We have a roadmap to scale up from 105m+ TVL through financial innovation, new products, and Opyn's protocol architecture.
