One of the things we've learned from our Robinhood Chain mainnet launch is that ecosystems can grow incredibly quickly when there is exceptional engineering behind them Huge credit to the Robinhood engineering team, and congrats to our friends and partners @arbitrum.

Over the past year, Offchain has worked closely with Robinhood to help bring their onchain strategy to production. That work started with supporting Stock Tokens on Arbitrum One and has now progressed to Robinhood launching its own dedicated blockchain on the Arbitrum Platform. This is exactly why we built Offchain Enterprise Services: to help ambitious fintechs and institutions design, launch, and scale production-grade blockchain infrastructure. Robinhood was our first Enterprise Services partner, and yesterday’s launch is a major proof point for what this offering is designed to enable. Arbitrum acts as the platform. Offchain brings the deep protocol expertise, infrastructure support, and execution experience to help partners move from ambition to production. Blockchain will power the future of the financial system. Our mandate at Offchain is to build the infrastructure that makes that future real.

This is a major milestone for @zerodev_app and the broader @Offchain product suite. We have been relentlessly focused on providing the infrastructure to support the programmable economy and providing the most seamless UX is absolutely critical. ZeroDev has evolved into a full product suite that developers can utilize to power their entire onchain experience. @decentrek can been leading these efforts for many years and today is the next chapter in his work to bring the world onchain. Go programmable. Go ZeroDev. If you haven't already, sign up and try it all out!

Embedded wallets solved part of the onboarding problem. Smart accounts solved part of the flexibility problem. ZeroDev Wallet brings those layers together. Embedded wallet UX, smart account depth, and gasless programmable flows through one platform.

The best onchain products will hide complexity from users without giving up control for developers. That is the promise of programmable accounts. ZeroDev Wallet brings embedded wallet UX and smart account infrastructure into one platform. Proud to help bring this next phase of ZeroDev to market.

Very happy to see Robinhood Chain Mainnet now live. One of the biggest strengths of @Arbitrum’s infrastructure is that it lets enterprises build whatever best fits their business. Robinhood's journey illustrates that well: launch tokenized stocks on Arbitrum One, validate with real users, then move to dedicated infrastructure as requirements around performance, security, and compliance become more specialized. This is why the Arbitrum Platform is so powerful. Enterprises can customize and evolve their infrastructure as their products and requirements evolve. As more financial products move into the programmable economy, different categories will need different infrastructure. Our goal is to give enterprises that flexibility while they scale the next generation of finance. Looking forward to seeing what developers build on the Robinhood Chain.
Arbitrum@arbitrum

Most platforms ask fintechs to make a bet before they know what customers want. The Arbitrum Platform lets our customers do the opposite. @RobinhoodCrypto launched Classic Stock Tokens on Arbitrum One, then migrated to a dedicated blockchain to customize performance, throughput, and governance. Here’s the story: blog.arbitrum.io/robinhood-chai…

It's been two weeks and the leading US model, Fable, is still banned by the White House with no explicit Congressional Authorization, no written rule that was broken, and no technical justification. In the meantime, our Chinese adversaries released a model that rivals our best.

Sad to hear of the passing of Peter Neumann, a respected and beloved mentor to me and many other infosec researchers. Among other things, Peter helped open my eyes early to the role of tech in public policy. We need more like him. The Times has a good obit: nytimes.com/2026/05/17/obi…

This is a big step for us at @Offchain. Over the years, our team has been contributing and bringing new innovations across different layers of the stack: Scaling Ethereum: @arbitrum Advancing L1 consensus: @prylabs Innovating smart accounts: @zerodev_app Each has played a role in pushing crypto infrastructure forward. Bringing them together puts us in a strong position to support institutions coming onchain with the flexibility and ownership they expect. Excited for this new chapter and looking forward to sharing what’s coming with everyone.
Offchain@Offchain

We're now Offchain. A new chapter focused on powering institutions as they move onchain. What we’ve built across @arbitrum, @prylabs and @zerodev_app is coming together into something bigger. This is just the first step. Stay tuned. offchain.io

@donnoh_eth @hasufl @spreekaway I don't speak for the Arbitrum community. But my view on this is that one shouldn't weaken a critical security parameter without first doing a serious written risk analysis.

we have been discussing these things deeply and extensively with all main L2s + EF in private for over a year now. i want to avoid arbitrum saying such changes are reckless but i think at this point we have good enough arguments on why it is reasonable. basically all L2s are in favor except arbitrum

call me old school, delusional or whatever you want but i still do believe the single most important job of an L2 is to provide a strong and secure default bridging infra to its users and apps. every time users are pushed to 3rd party bridges like L0 it is a failure for such L2
Hasu⚡️🤖@hasufl

This doesn't even consider that 2/3+ of user assets on L2s are not minted by the rollup bridge at all, but by third-party committee bridges. It was a funny time while we all thought that the L1 bridge is the most important part of a rollup.

If you're at EthCC, come see my mainstage talk at 11:15, with some real talk about how we can get the Eth stack to a billion users, and an update on Arbitrum advances.

@econcallum @alexcdot I responded to clarify because the original tweet said "vulnerability" and "at-risk" which reads as less neutral.

Shortly after ChatGPT was released, a paper came out which estimated the vulnerability of different occupations to AI disruption. Since then, the MOST at-risk occupations have grown by the MOST. The LEAST at risk-occupations have grown by the LEAST. 🤪

@econcallum See the top of section 2. "The term 'exposure' is used so as to be agnostic as to the effects of AI on the occupation, which could involve substitution or augmentation depending on various factors associated with the occupation itself."

@econcallum This point is often misunderstood, unfortunately. Our paper's metric relates to the *magnitude* of impact on a job, but not the *direction*. Direction is much harder to predict.

This is a very cool moment. Seeing the technology we at @Offchain Labs have been building for the past 8 years adopted by a Fortune 500 company is incredible. The best part about deciding what features to ship for the Arbitrum stack (Stylus, Timeboost, the new pricing algorithm, etc.) is that we can now do so with multiple environments in mind that all have different target use cases, who may or may not want to adopt specific features: @Arbitrum One for general finance and settlement @RobinhoodApp as rails for their app and DeFi for Stock Tokens @edgeX_exchange for pure execution on their perps exchange Just to name a few! While this is only a testnet, I’m very excited to see what developers will be able to build with Stock Tokens as assets with Arbitrum powering all of it.
Arbitrum@arbitrum

Robinhood Chain testnet is now live on the Arbitrum platform. Phase 1 focuses on developer onboarding and infrastructure testing: Testnet gas + Stock Tokens Contract deployment Bridging + explorer visibility This allows tokenized asset flows to be tested without production risk. ⚠️ Testnet assets have no real-world value.

Deeply saddened to hear of the passing of Dave Farber. He was a true pioneer who had major influence on the architecture of the Internet and tech policy. Rest in peace to one of the most "Interesting People" our field has ever known. mailarchive.ietf.org/arch/msg/ietf/…
