Arbitrum: The rails powering asset tokenization in the programmable economy 🤝 Robinhood Chain

Huge opportunities await teams in the programmable economy Bring $USDG to your lending, yield, AMM, or payments app on Arbitrum and apply to the Stablecoin Growth Program: airtable.com/appNPlINVhkcwny…

At @ycombinator, we're excited to fund more crypto startups solving financial needs including AI capital raising, stablecoins, trading, and agents. Here's our latest crypto request for startups. Our next application deadline is Monday.

It’s the final day of Founder House Singapore with Robinhood Chain 🇸🇬 Submissions are in, and we’re finalizing the lineup of teams taking the stage to pitch their products live to our panel of judges. Stay tuned for the pitches and winners announcement!

Why did Robinhood choose Arbitrum to power Robinhood Chain? ✅ A strong fit between our teams ✅ Proven track record of building and scaling blockchain infrastructure ✅ A faster path to launch, so Robinhood could focus on the financial products built on top

Day 2 at Founder House Singapore was all about refining apps and planning for growth Hear @0xjesstech break down what founders took away > Clearer plans for GTM, product and fundraising > A sharper product strategy and growth roadmap > Mentor feedback to help refine their apps Get ready for Day 3 with Arbitrum and Robinhood Chain

Day 2 at Founder House Singapore 🇸🇬 Today is all about getting your product in front of the right users, with a focus on GTM strategy, distribution, and finding the right path to growth. Follow along for more updates from the ground. 👇

Final call for founders 🗣️ Bring your app onchain at Founder House next week in Singapore with $300K in prizes and grants. In collaboration with Robinhood Chain, see what’s in store for founders each day from October 23rd-25th. Register today: luma.com/openhouse-singapore…

3 companies YC rejected… then became unicorns. 1/ Webflow - rejected Nov 2012 - Designs, a vision, no working product. YC passed. - So Vlad Magdalin cashed out his 401k, maxed $60k in credit cards, sold both cars, and built it. - Posted the prototype to Hacker News → 20,000 signups overnight. - Reapplied. Got in. S13. Now: ~$4B. 2/ Replit - rejected 3x - Never even made it to an interview. “Not a real business.” - Then Paul Graham spotted it on Hacker News. Sam Altman slid into Amjad Masad’s DMs. - W18 Late look granted. - (He replaced his pitch video with a Rickroll. They took him anyway.) Now: $9B. 3/ Legora - rejected May 2023 - The pitch: querying legal docs with LLMs. Sounded thin at the time. - Reapplied with proof. Got in. W24. Now: $5.5B + one of the fastest-growing companies in legal AI, reported 8.5 coming soon

We’re hiring top engineers and options traders to build onchain options and structured products at @o1_exchange. You’d be a fit if you know (or can learn fast): 1. Black-Scholes-Merton, Brownian motion, Itô calculus, discrete-time models 2. Liquidity bootstrapping for CLOBs, liquidity vaults, RFQ, AMM infra 3. Delta-neutral options hedging Signals we look for: 1. IMO / IOI / ICPC / IPhO medalists 2. High Codeforces ratings 3. Founders who’ve built something real from zero 4. Quants at HFT shops (HRT, Jane Street, Citadel) or FX / options / exotics traders at banks (Goldman, JPM, Deutsche Bank) My X DM is open. JD: app.notion.com/p/o1-exchange…

Turns out the future does have flying cars

Today I call upon the blockchain industry to calmly begin planning for "bunker mode". My personal recommendation is to set in motion a controlled mass migration of assets to fresh addresses, i.e. addresses whose pubkeys remain hidden behind a hash. Holders, starting with large and sophisticated ones, should consider moving the bulk of their funds to addresses that have never signed a transaction. And when they do sign one, they should also move remaining funds to a new address (possibly generated from the same seed phrase). Don't rush. While I believe there is cause for action a rushed migration would do more harm than good. Don't panic either. Moving assets to protected addresses is a simple, preventative step which does not require new cryptography or new wallets. IMO it is now reasonable to brace for the possibility that ECDSA breaks before qday, in the worst case in months not years. By "break" I mean fast private key recovery (e.g. in one week) on available hardware (e.g. a large GPU cluster). Recent days have been humbling for human mathematical intuition. Long-held, unquestioned hypotheses have fallen. This includes the n log(n) bound for integer multiplication and the 3SUM conjecture. In hindsight, May's unexpected disproof of the Erdős unit distance conjecture was our warning shot. Yesterday's OpenAI drop made it clear that mathematical superintelligence is upon us. They say there are weeks where decades happen. We are about to live through weeks where centuries of mathematical progress happen. Could our magic 64-byte ECDSA signatures be too good to be true? Was it just security through obscurity all this time? Elliptic curves feel especially vulnerable to superintelligence. Curves carry rich structure, with room for fancy tricks like Schoof, Frobenius, pairings. (By contrast, hashes are designed to minimise algebraic structure.) Separately, as Ewin Tang can attest, an efficient quantum algorithm sometimes foreshadows an efficient classical one. We should be open to the possibility of a classical counterpart to Shor that breaks elliptic curves and RSA at once. Also noteworthy is the striking under-representation of cryptographic breakthroughs among the 722 mathematical results OpenAI published. I've witnessed first-hand the US government censoring academic quantum cryptanalysis results. Backroom interventionism is my base case. I urge large, sophisticated actors to lead by example. Project11's "risq list" (bitcoin-risq-list.projecteleven[.]com) is a great tracker of exposed BTC pubkeys. Binance, Bitbank, Robinhood, Bitfinex, and Tether have an opportunity to harden their cold storage. Next month I'll address institutions in London in a live Q&A (forum.ethereuminstitutional[.]org/london-2026). Again, please do not rush. Wallets holding under 50 BTC enjoy partial cover from "Satoshi's shield", i.e. his 20K exposed addresses that hold 50 BTC each. Load-bearing signers like oracles and L2 security councils should consider rotating ECDSA pubkeys with every signed message and/or multi-signing with a hash-based schemes like SPHINCS. Exiting bunker mode safely will require post-AI cryptography. My inclination is to go all-in on hash-based cryptography and avoid structured mathematical assumptions entirely, whether from curves, lattices, or isogenies. A single battle-tested hash (e.g. from the SHA or BLAKE families) yields plausible post-AI security. The Ethereum roadmap on strawmap[.]org fully embraces hash-based cryptography with end-to-end formal verification as a response to the quantum threat. Those timelines must now be revisited and accelerated in light of mathematical superintelligence. I'll be pushing for maximum defensive acceleration.
