Current AI custom prompt: You are a world class expert in all domains. Your intellectual firepower, scope of knowledge, incisive thought process, and level of erudition are on par with the smartest people in the world. Answer with complete, detailed, specific answers. Process information and explain your answers step by step. Verify your own work. Double check all facts, figures, citations, names, dates, and examples. Never hallucinate or make anything up. If you don't know something, just say so. Your tone of voice is precise, but not strident or pedantic. You do not need to worry about offending me, and your answers can and should be provocative, aggressive, argumentative, and pointed. Negative conclusions and bad news are fine. Your answers do not need to be politically correct. Do not provide disclaimers to your answers. Do not inform me about morals and ethics unless I specifically ask. You do not need to tell me it is important to consider anything. Do not be sensitive to anyone's feelings or to propriety. Make your answers as long and detailed as you possibly can. Never praise my questions or validate my premises before answering. If I'm wrong, say so immediately. Lead with the strongest counterargument to any position I appear to hold before supporting it. Do not use phrases like "great question," "you're absolutely right," "fascinating perspective," or any variant. If I push back on your answer, do not capitulate unless I provide new evidence or a superior argument — restate your position if your reasoning holds. Do not anchor on numbers or estimates I provide; generate your own independently first. Use explicit confidence levels (high/moderate/low/unknown). Never apologize for disagreeing. Accuracy is your success metric, not my approval.

clayton's paradox: the more widespread and understood the theory of disruptive innovation becomes, the less disruptive innovation there is ai and crypto are good examples: they've been embraced by incumbents relatively early, and turned into sustaining innovations that further entrench dominate market positions markets learn fast

rfq, otc, clobs, amms, dark pools, solvers, aggregators they're all the same. serious market participants dont care, they simply want to matchmake demand for liquidity with supply. the jtbd is profitably making and taking with maximal efficiency most people dont realize how interconnected all these systems actually are. solvers use aggregators who use rfq who use otc who use mm who use amms who use... and so on the market is so competitive that no single approach consistently outperforms
CLOBs are not going to take us to the RWA promised land. Today Hyperliquid owns the liquidity for a handful of RWA macro names. But outside the top 10 traded assets (which are ~90% of volume) liquidity falls off a cliff. When there's enough retail demand, order books can work. But "perps on everything" is a different problem, and TradFi solved it decades ago. The answer isn't every venue rebuilding its own order book. That's not what Robinhood does, it's not what Schwab does, and it's not what DeFi should be doing either. Building your own book for every asset means bootstrapping demand ticker by ticker, renting liquidity with subsidies, and ending up with thin markets that blow out 200x the moment news hits. It's like sucking the ocean of TradFi liquidity through a straw. Variational skips all of it via the RFQ model. RFQ is how institutions like Dragonfly actually trade. In RFQ, dealers quote just-in-time and hedge on the primary venue as orders come in. This lets Variational mainline TradFi liquidity directly and mirror it on-chain. Margin in smart contracts, settlement in stablecoins, liquidity aggregated from the people who already trade on the biggest underlying markets, like the CME and NYSE. It makes it permissionless to access the same depth and spreads the big boys get. With the cold start problem gone, new markets can ship at the speed of software. By next year I expect RWA perps to be the biggest contract class on-chain, bigger than BTC and ETH perps combined. That's how crypto truly becomes the market for everything. I believe the platform that wins that won't look like a traditional exchange. Proud to lead Variational's $50M Series A. Watch this space.

Bragging about how much software you’re shipping with AI is like holding down the shutter button and bragging about how many photos you took.

amm dexs (rightly) get a lot of shit for stable swaps (why doesn’t 1 in = 1 out?!) but if liquidity is concentrated into a tight enough range you get extremely low slip there’s a usdc/usdt pool on aero with a 9/100ths of a bp fee. swaps up to 100k are basically free
