Users can purchase American-style options on Premia’s custom AMM by first selecting the details of the option they'd like to trade, like the token pair, strike price, and maturity. Once the details have been entered, the user will receive a quote denoted in terms of the underlying asset for call options or the base asset for put options. If the user agrees with the price, they can execute the transaction to facilitate the trade and purchase the option for the quoted price.
