2023, oh, what a ride in the world of DeFi! 🫠 USDC de-pegging worked a scene, causing SVB to feel a painful lean, into bankruptcy of $209 billion it did sink. 😈 Masking as a validator did the "low-carb-crusader," unbundling, stealing $20 million from sandwich bots, no later.

👉 What’s your biggest concern regarding value redistribution in the MEV supply chain? 👉 What's your opinion on builder-searcher integration? 👉 About MEV Burn and PEPC, do you think they could be helpful in terms of aligning incentives in the ecosystem? 👉 Which metrics are crucial for observability in the MEV Supply Chain? 👉 What does it take for a searcher to back-run a sandwich bundle or, more generally, Private Order Flow? If these questions are bugging you, tomorrow 7 PM ET, join these builder experts: ⭐ Benjamin Hunter @philosowrapter, Software Engineer from @bloXrouteLabs ⭐ Blair Marshall @blairlmarshall, Product Manager of @blocknative ⭐ Danning.eth @sui414, Data Scientist of Flashbots ⭐ Julian Villella @JooleanVillella, Co-founder of @gmbitco ⭐ @Sophie_EigenPhi, Data Scientist of @EigenPhi 🎤 x.com/i/spaces/1drkz…


MEV searchers typically send bundles to the builder's private RPC, keeping them hidden from others. But when searcher-builder integration comes into play, it unleashes some 🤖 game-changing advantages, illustrated in the above examples. Discover more in our thread 👇

Arbitraging on #Uniswap is not easy. Typically, the median Cost-Revenue Ratio for spatial arbitrage (moving 2 assets between 2 pools on #Uniswap) on UNI is around 99%. However, if you are a searcher integrated with builders, the CRR can be as low as 11%!!


Validators used to claim over 70% of the profit in MEV supply chain. But now, with searcher-builder integration on the rise, their income is shrinking. We examine how Back-of-Block MEVs targeting private OF from @bananagun alike are changing the game: eigenphi.substack.com/p/transaction-….


Glad to support this incredible @defi_workshop at renowed @acm_ccs ! It’s great to be a sponsor along with @d23e_AG @Uniswap @EigenPhi @BlockSecTeam @GotCHA_labs!

Today, ~15% of Ethereum Txs are landed thru Private Mempools. Cross-checking txs seen by public mempools, we are able to observe the trend of Ethereum txs moving towards private channels over time - thru metrics across the Tx Settlement Stack on Ethereum. 👀 🧵👇

Finally got to do a bit of self-promotion 3 months after the paper was done ... In this paper, we (@aadams @Vervious @saritmarkovich and yours truly) dive deep into the current DEX swapping experience on Ethereum, quantifying cost components. blog.uniswap.org/auditing-mev-s…




Peter ( @MrSnookems ), VP of EigenPhi, introduced the team and our grand vision to all the gigantic brains in the room of DeFi.Security workshop.

Our Chief Data Scientist, @playerYixin, gave an epic talk at MEV & Intents Day thanks to @blockswap_team's invitation. Prepare for the analysis of C0ffeebabe.eth's behavior and performances by 4 top MEV arbitrage 🤖 during the Curve-Vyper exploit. 📺 youtu.be/SCSOhdyQNL0

Great post. The MEV centralization part is a very overlooked area as David mentioned. It is also MUCH harder problem to solve, even beyond the disagreement if it is even a problem at all. There is a smaller set of very profit motivated actors and entities in an area of crypto (MEV) that much fewer people understand. At least in general Ethereum protocol disagreements there are generally straightforward ways to explain to a non-dev crypto user what is going on. It's not impossible and there are a very limited amount of people in the MEV space who can accomplish this. The question is will their time be pulled in different directions due to the lack of coordination resources available for many of the other hard problems in MEV. I'm still hopeful 🙂
