On-Chain options refer to option contracts, traded directly on a decentralized exchange on the Ethereum blockchain.

We report a novel set of stylized facts about the functioning of this so-called automated market making for options trading. We document the extent to which the On-Chain options differ from their Off-Chain counterparts traded on centralized exchanges. In particular, we identify a difference in implied volatilities between On-Chain and Off-Chain options, attributing it to factors like the complex On-Chain fee structure, trading volume, and net demand pressure.

We propose a theory explaining the difference in implied volatilities and empirically verify key model implications.
