Life update: I've joined the @renegade_fi team to build crypto's leading dark pool! Here's why I'm excited to work on Renegade:

The Time to Build essay is a different flavor of idea, no? This seems like a somewhat deliberate misinterpretation of that essay aimed at creating hypocrisy from thin air... We should build in my backyard (the Haight) where it makes sense to have large, multi-family housing projects. Building housing everywhere just doesn't make sense. You wouldn't build an apartment complex in Big Sur, so clearly there is a line. It seems pretty clear to me that a place as serene as Atherton is beyond that line. I don't even live there, nor would I particularly like to, but it does seem worth keeping a few places "small"

AI Notkilleveryoneism Memes ⏸️
5 years ago, Marc Andreessen wrote "It's time to build." Today, he is going OUT OF HIS WAY to block homes from being built in his town - the most expensive zip in the USA. In his letter, he didn't even try to hide why: "They will MASSIVELY decrease our home values."

If transparency improves execution, then why do 35% of US equities trade in dark pools? The data disagrees — around 12% of volume is matched in crossing networks (e.g. MS Pool, SigmaX), and around 23% of volume is retail internalization. Are all of these traders just irrational? ETF example — these funds hit the close because their mandate is to track the benchmark, not to optimize execution costs! History of electronic markets — history doesn't stop in the early 2000s. As lit books went electronic, we also got block-crossing, icebergs, and mid-pegs, all of which hide intent. The spectrum of information — the better model here is that the spectrum gives traders a choice in the price vs. time tradeoff. L0 = slower trading = lower impact, and L4 = faster trading = higher impact. How market makers react to information — segmentation is orthogonal to privacy. You can have a private but segmented book (e.g. SigmaX) and you can have a transparent but non-segmented book (e.g. Binance). I think the real answer here is just that privacy has been so incompatible with decentralization and low-latency trading — this changes very soon w/ @renegade_fi Hyperliquid.

@lyronctk Yeah exactly, it's about ~3M gas on Arbitrum to settle a trade. This isn't too bad actually, but there are tons of new things that could be built were gas cheaper.

@jkraut_ Ah I see, because trade settlement on Renegade is a ZKP verification + merkle tree insertion right? How much does that cost on Arbitrum One for you?

Driving fees to 0 on a general purpose chain is overrated I've never met a regular uniswap / pendle / morpho user who complained about a $0.01 base fee

Announcing Axiom: Eliminating drug toxicity, without using animals! Alex Beatson and I founded Axiom a little over over a year ago with the mission of eliminating drug toxicity by replacing traditional experiments, such as animal testing, with AI models. We are excited to announce that we've raised $15M in seed funding from Amplify Partners, Dimension Capital, and Zetta Ventures to get this done. It has been a wild ride since we got started. Within our first year, we've created the world's largest human toxicity dataset, encompassing data on over 100,000 molecules generated through proprietary lab methods combined with 1000s of clinical outcomes structured using LLMs. With this dataset, we trained an AI model which predicts drug-induced liver injury more accurately than traditional physical experiments, addressing a leading cause of clinical failure recently exemplified by Pfizer's discontinued obesity drug. We publicly launched this model at the Society of Toxicology conference in March and the response has been tremendous! We're actively conducting or finalizing pilot studies with diverse partners, including six of the twenty top pharmaceutical companies, a major agrochemicals firm, many biotechnology companies, hedge funds, and strategic partners. We're honored to partner with these insanely great scientists to rigorously assess our AI models and explore how to best integrate them into their drug discovery workflows. The expertise of these scientists is crucial for validating and thoroughly evaluating these new methods. We have multiple publications out already but we plan to share a lot more data from these early pilot studies in the coming months. At the same time, the FDA recently announced plans to phase out animal testing over the next few years, emphasizing that animal studies will become "the exception rather than the norm." The HHS Secretary RFK has said that "they have found AI to be much more precise in identifying the impacts of toxins" on the human body. With our recent progress, Axiom is uniquely positioned to support the FDA and scientific community in realizing this shift. We will eliminate clinical trial failures due to toxicity. And we don't need animals to do it. For more, you can read Andrew Dunn's Endpoints article on Axiom in the comments.

At this point, dark pools will always be the best solution. They’re reshaping how large trades are executed, offering privacy and reduced price impact for sophisticated traders and investors. @renegade_fi is the first on-chain dark pool, using MPC matching with zero-knowledge settlement to combine privacy and decentralization. Orders are never exposed to the public until finalized. Why Renegade? ➡️ Pre/Post-Trade Privacy: Orders stay hidden until matched. No strategy copycats. ➡️ Midpoint Execution: Trades clear at Binance’s real time price, zero spread, zero slippage. ➡️ Zero MEV: Validators only see ZK proofs no front-running, ever. ➡️ Opt-In Compliance: Stay decentralized but match with verified counterparties.

A Costly Lesson in Crypto: The $216k Sandwich Attack on Uniswap v3 Even a simple swap can turn into a nightmare. Here's what happened to one user who lost $216k while trying to swap $221k usdc to usdt on uniswap v3 and end ended up getting just $5k. The user initiated the swap using the old uniswap v3 swap router (not the newer Universal Router) and, shockingly, set the slippage to 100%. This left the transaction wide open for exploitation. Enter an MEV bot. It spotted the vulnerable transaction and quickly front-ran it by swapping out all the USDC liquidity, drastically skewing the price. After the user's transaction executed at the worst possible rate, the bot back-ran the trade by restoring the liquidity. The user lost $216k, while the attacker pocketed a cool $8k profit. To make matters worse, the attacker tipped the block builder (bobTheBuilder) a staggering $200k to ensure their malicious transaction was included in the block. The Takeaway: Always use trusted interfaces like the official Uniswap interface, which suggests reasonable slippage settings. Avoid setting slippage to extreme values (like 100%) unless you absolutely know what you're doing. And remember, in DeFi, vigilance is your best defense. Stay safe out there!

@jillgun @tangle_network @renegade_fi @cardinal_hq I swear, every time I go to implement a new crypto primitive, Espresso has a rust implementation ready to go… Jellyfish in particular is really great, saved us a serious amount of time and has a very fast prover. Kudos to the team for all the contributions to open source!

Incredibly proud of everything the Espresso team has shipped in the last 4 years, so a little recap: 1/ ☕️⛓️: a chain purpose-built for fast, secure cross-chain confirmations (& performant DA) Running on permissioned mainnet since November, first chains integrating now 👇

@benafisch @EspressoSys industry will be thankful to espresso’s contributions on each of these long term!🫡
