Not a dumb question at all thanks for the feedback! The repo you linked is the most up to date version of the contracts. You can find them on the smart-contracts branch: https://github.com/opynfinance/Solidity-Contracts/tree/smart-contracts

Our recent updates have been through integrating with dYdX using their Solo protocol: https://github.com/dydxprotocol/solo

Also, feel free to ask questions and discuss on our discord https://discord.gg/2NFdXaE :)

We’re always looking to improve the product and would love any additional feedback. If you have some time, we would love to hop on a short call to chat further — we can schedule via hello@opyn.co if you’re interested.
