Trying to get o3 to write a paper for me and it got stuck on a pretty basic misunderstanding of AMMs and path dependency So we're now 10 messages deep into an argument about it Incredibly addictive, this will replace Twitter

The deeper you get into DEX design, the sillier it feels to be dogmatic about any of it Everything depends on fiddly microstructure details

Is there any way to do an onchain prediction market for p(doom)? Given the impossibility of settlement in the apocalypse and the difficulty of credit in the non-apocalypse case

“Don’t use chains with centralized sequencers, since someday they might subtly extract value from you Instead use decentralized sequencers that are guaranteed to extract maximum value from you, today”

I don’t think whether a sequencer is decentralized matters too much What matters most is what rules they follow, and particularly whether they use their power to hurt users or extract value You can have extractive decentralized sequencers, or nonextractive centralized ones

Here's a mystery: AMMs seem to be much more profitable when buying ETH than selling it Look at how these cumulative markouts (grouped by direction) diverge over time The pool made >$20m from its ETH buys, but lost >$24m from its ETH sells! Any theories?

These are the cumulative 15m markouts for the Fluid ETH/USDC pool. It has bled out $8.5m in EV, and its trades were unprofitable all the time, not just during rebalances. There are no profits to make up for the costs from rebalancing. The pool never makes money in expectation.

Respect for @0xfluid posting this post-mortem But their proposed solution—to make liquidity more concentrated—seems like the wrong choice The pool is not just losing money during rebalances. It is losing money constantly—AFAICT, fees do not make up for arb losses So concentrating liquidity more would be a double whammy—faster loss to arbs between rebalances, and more frequent rebalances

Fast trustless bridges usually require payments to be locked up in escrow But what if users could just send to the relayer—trustlessly, and at a fraction of the capital and gas cost of the escrowed model? Introducing Across Prime, a new design from me @hal2001 @mrice32 🧵

#USRetailSalesMissForecast U.S. Retail Sales Miss Forecast: Quick Take U.S. retail sales stalled in December 2025, coming in at 0.0% growth against a predicted 0.4% increase. This "flatline" suggests that despite a strong stock market, the average American consumer is reaching a breaking point due to high living costs and job insecurity. The Breakdown * The Miss: Sales growth (2.4% YoY) is officially losing the race against inflation (2.7% CPI), meaning people are paying more but getting less. * Winners & Losers: While people spent more on building materials (+1.2%), they pulled back sharply on "wants" like furniture (-0.9%) and electronics (-0.4%). * The "Why": A combination of depleted savings, a 7.7% unemployment rate, and the lingering psychological impact of the recent 43-day government shutdown. What This Means for the Market * Interest Rates: The "miss" actually fueled hopes that the Federal Reserve will cut interest rates sooner to jumpstart the economy. * Stock Reaction: Markets remained steady as investors prioritized the hope of cheaper borrowing costs over the news of lower consumer spending. The Bottom Line: The American consumer is finally "tapped out." All eyes are now on the upcoming tax refund season to see if it provides the necessary spark for a Q2 recovery. $ETH $XRP $PEPE #USRetailSalesMissForecast #USTechFundFlows #WhaleDeRiskETH #GoldSilverRally
