Dopex is a decentralized options protocol which aims to maximize liquidity, minimize losses for option writers and maximize gains for option buyers - all in a passive manner for liquidity contributing participants. Option pools are created for all options on Dopex, which allows anyone to participate and deposit base/quote for their respective pools to gain passive income from option writing and purchasing discounted options through liquidity pools which could then be arb-ed for an instant profit. The protocol is governed by users via a limited supply governance token, DPX, which would also be used for collecting protocol and app layer fees. Dopex also offers a rebate system for losses incurred for option writers based on exercised options for every epoch. The rebates are paid in the form of a theoretically infinite supply token, rDPX. Rebates are calculated based on percentage losses incurred by option writers for an epoch and a percentage of rDPX relative to the value of losses incurred are minted and distributed to option pool participants. The percentage rebate is determined by a governance process based on votes by DPX holders within the protocol. The rebate allows for option writers to gain a superior return in comparison to writing naked options or hedged option writing strategies of any sort. rDPX can in the future, also be used as collateral to borrow capital from the margin pool to leverage option positions or to mint synthetic derivatives of assets supported within the protocol such as - cryptocurrencies, stocks, ETFs, commodities, currencies etc. This inherently gives the rDPX token real value and creates a positive feedback loop for liquidity to grow and option writers/traders to participate considering the deep liquidity, cheaper options to purchase and higher ROI from option writing.
