Specifically interested in latency, what domains it communicates with, security parameters, etc. - **Q2:** What specific apps do you see using cross-domain comms? Do any of these exist in the wild? Is there a use case that's not a token bridge? - **Q3:** How does cross-domain MEV differ from MEV within a single chain or L2? - **Q4:** What unique challenges does cross-chain messaging pose to MEV extraction? What about for devs or users that want to defend against MEV? - **Q5:** Some MEV defenses rely on hiding transaction contents. Is privacy in cross-domain messaging a priority? Is it even achievable? ## 2.

Is there a “fair” distribution of MEV in your mind? How do you achieve that? - **Q2:** In a world where MEV shifts away from miners and bots, do you think it’s more likely that it shifts to DAOs / protocols or just back to individuals? Is there some third option? - **Q3:** Thoughts on shift to PoS? What are some potential second-order effects of the move to PoS wrt MEV accrual that we might not be seeing right now? What about rollups? - **Q4:** What’s the next frontier on the bot space? Is generalized frontrunning the end game, or are there novel techniques and technologies you see people employing now or in the future to get an edge? ### 4.4 Hybrid model of MEV minimization & democratization - 18:20 - 19:00 ET | **(Panel) MEV: Next frontier of the DeFi stack** - *Dan Elitzer (moderator), Luciano Bertenasco (Yearn), Joe Delong (Sushiswap), Scott Bigelow (Flashbots), 1inch (TBC)* - **Q1:** How much of a negative impact do you think MEV has on DeFi users and protocols today? - **Q2:** Can you give any examples of features you’ve either designed with MEV in mind or considered and discarded due to MEV concerns? - **Q3:** A protocol’s MEV represents a lower bound of the value being extracted from the protocol and its users by outside parties. To the extent that some amount of MEV is unavoidable, have you considered any approaches protocols might use to internalize MEV opportunities to the benefit of tokenholders or protocol users? - **Q4:** DeFi users today tend to interact with protocols directly through an official front-end. How much responsibility do dapp developers have to implement some sort of MEV protection or private transaction submission to protect their users at the interface level? Is this more of a wallet-level issue? - **Q5:** Assuming composability tradeoffs were not a major issue for a particular DeFi protocol, should they ever consider launching on an application-specific rollup (or other chain) where sequencing is tied to governance tokens in some way?
