What is ACO ?
ACO is a decentralized American options protocol created by Auctus. Users can mint call and put options for different markets at different strike prices, and sell tokens which represent those options to other users. ACO tokens are tokenized options that convey to its holders the right, but not the obligation, to buy or sell an underlying crypto asset at a specified price (Strike Price) at any time before or at expiration.
