    The gaslighting here is astonishing. Acting President @ClaireShipman should speak for herself. As a @Columbia faculty member I do not share her values of authoritarian university governance and enforcement of ideological conformity, all to advance a racist Trump admin agenda.

    Acting University President Claire Shipman, CC ’86, SIPA ’94, described Columbia’s Wednesday agreement with President Donald Trump’s administration to pay $220 million to restore funding as “in line with our values” in her first interview with Spectator. l8r.it/agLK

    The two most popular mechanisms for onchain trading are AMMs and Dutch auctions. Both leak MEV to arbitrageurs. For AMMs, this is now well understood as loss vs rebalancing (LVR). What about Dutch auctions? New paper with @danrobinson 🧵

    New research alert! With @The_Zhukeeper @xin__wan @danrobinson @BradBachu, we show that, counterintuitively, protecting users from paying fees for failed transactions can increase total fee revenue!

    New paper alert! We propose a novel AMM design that seeks to address two interrelated questions (1) how should an AMM set the trading fee? (2) How can an AMM mitigate LVR / liquidity provided losses to arbs.

    New Paradigm research from me and @ciamac! Prediction markets were the original motivation for AMMs, but today they mostly use orderbooks One reason: outcome tokens don't behave like other assets We present the pm-AMM, a new invariant designed for prediction markets 🧵

    This is at best misleading. Dark pools suffer transaction costs through adverse selection: you are more likely to get filled when prices are moving in your direction and you'd prefer not to. This is a real cost!

    Dark pools enable sales with zero price impact. Since crossing networks provide a way to "cross" natural buy and sell flow, trading with Renegade means guaranteed best execution, with zero price impact whatsoever! x.com/renegade_fi/st…

    Interesting discussion between @0x94305 and @AndreaCanidio, both of whom are experts and have thought deeply about DEX design, on evaluating the real-world performance of @CoWSwap AMM. Two questions I'd like to discuss: 🧵

    I think to evaluate a new type of AMM, you need to check whether LPs make more money by LPing in the new AMM than the alternative. The rest is an interesting intellectual exercise.

    The future holds a million stablecoins. Today's infra isn't ready. Introducing Orbital, an automated market maker for pools of 2, 3, or 10,000 stablecoins. Orbital unlocks capital efficiency by bringing concentrated liquidity to higher dimensions. w/ @danrobinson @ciamac 1/8
