Order-Flow Auctions & MEV Redistribution

You already know the ugly truth from the MEV course: the moment you broadcast a swap, you hand a stranger the right to reorder the block around it — to front-run you, back-run you, or sandwich you — and the value that gets squeezed out flows up the supply chain to searchers, builders, and validators. You created the opportunity; everyone but you got paid.

This course is about the counter-movement. The frontier of MEV research has stopped asking “how do we stop extraction?” (you mostly can’t) and started asking a sharper question: “if value is going to be extracted from your order, who should keep it — and can we route it back to you?” That single re-framing — redistribute, not just minimize — has produced the most important DeFi infrastructure of the decade.

We build the machinery piece by piece:

• The redistribution turn — why “give the MEV back to the user” is the verb that reorganizes the whole supply chain, and what makes the user the natural owner of the value.
• Order-flow auctions (OFAs) — sell the right to back-run your transaction in a sealed auction, then refund you most of the winning bid. The “redistribute” verb made concrete, with the refund-split arithmetic worked out.
• Intents & solvers — stop signing transactions and start signing outcomes; let a competitive field of solvers bid to fill your intent best. UniswapX as a Dutch auction over your trade.
• Batch auctions & coincidence of wants — CoW Protocol’s uniform clearing price, peer-to-peer matching that skips the AMM (and the MEV) entirely, and why settling orders together beats settling them one by one.
• MEV-Share & SUAVE — programmable privacy that reveals just enough of your order to be useful, and the decentralized-sequencing endgame that tries to make the whole auction layer credibly neutral.
• Mechanism design & the hard tradeoffs — price improvement versus solver centralization, censorship, trust assumptions, and how to tell a real redistribution mechanism from a rebranded toll booth.

This sits at the very top of the crypto ladder. It assumes you can already reason about the MEV supply chain (PBS, MEV-Boost, searcher bundles) and about on-chain arbitrage and the cost stack that bids most of a searcher’s profit away. By the end, “I made a swap” becomes a design choice: which auction you route into, who competes for your flow, and how much of the value you create comes home.
