What are the unique benefits of Optix? (1.) Options on alts - any erc20 can be used as collateral and any oracle for the strike price; (2.) Capital efficient - collateral in a single vault can be used to to sell options across multiple oracles, put/call directions, expiries & strikes; (3.) Simple user experience - option buying and selling is typically confusing and complicated. We aim to make it as simple as using a crypto dex; (4.) Permissionless structured products - create structured products from existing defi primitives; (5.) Permissioned DeFi - buy and sell to only regulatory compliant participants; (6.) Block trading - block trade any asset with kyc'd participants.
