Online Event | CLVR Ordering of Transactions on AMMs | Web3 Devs underground
·OnlineOnline🎙️ Hosted by: Web3 Developers Underground × the Blockchain & Digital Finance Lab (BGU)
⚡ Powered by: Masterkey VC
MEV is the hidden tax on every DeFi trade - and AMMs are ground zero. But what if transaction ordering itself could be redesigned to be fair by default?
💥 Join us for a deep technical dive into CLVR ordering - a mechanism that rethinks how AMMs sequence transactions, eliminates sandwich attacks by design, and fundamentally changes the economics of front-running.
If you're building or auditing DeFi protocols, this one goes straight to the core of how value actually flows on-chain.- Date: Wednesday, May 13th
- Time: 10:00 EDT | 16:00 CET | 17:00 Israel Time
- Where: Streaming Live on X (Twitter), YouTube, and LinkedIn.
🎤 Meet the Experts
- Dr. Nir Chemaya | Assistant Professor @ Ben-Gurion University
🔬 What We're Breaking Down:
⚙️ CLVR Ordering Explained: What it is, why it matters, and how it departs from first-come-first-served transaction sequencing.
🥪 Sandwich Attacks - Anatomy of the Problem: How arbitrageurs exploit mempool visibility, and why standard AMM designs are structurally vulnerable.
📐 The Math Behind Fair Ordering: Batch auctions, uniform clearing prices, and the tradeoffs between fairness, latency, and throughput.
🔁 CLVR vs. Existing Solutions: How it stacks up against commit-reveal schemes, encrypted mempools, and MEV-auction approaches like SUAVE.
🏗️ Protocol Design Implications: What CLVR ordering means if you're building an AMM, aggregator, or intent-based trading system today.💡 Backed by Masterkey VC
