Today we are announcing that S&P Global has entered an agreement to acquire OpenZeppelin. Onchain finance is growing from an emerging market into core financial infrastructure, and the standards and rails our team and community built are becoming the rails of global finance. OpenZeppelin smart contracts facilitated over $37 trillion in value transferred, with the vast majority of the largest DeFi protocols, blockchain networks, stablecoins and tokenized funds relying on them. With S&P Global, we expect to accelerate the impact of onchain finance, backed by more than a century of trust in global markets, benchmarks, and risk frameworks. To our clients and to all the users of OpenZeppelin open source tools: • OpenZeppelin Contracts and all our open source applications and tools remain open source, free, and publicly maintained on GitHub. Building open source standards stays a core priority. • Audits, engineering work, and ecosystem programs continue with the same team, brand, quality, and customer experience, with what will be the added benefit of S&P Global's research capacity, market data, and institutional reach. For the last decade, OpenZeppelin has set the security standard for onchain finance. Today begins a new chapter for that mission, together with one of the most trusted names in global markets.

Introducing @hob_app - the independent workspace for serious agent work. Run agents in parallel. Switch models without losing context. Trace every output back to the conversation that made it. → Launch offer: 2 months free, then a special price locked in👇
@VittoStack Would it be possible to join? 🫡
In June I’m hosting a meetup with workshops on IDEs, agents and workflows. It will be in Barcelona or Girona (maybe boths) Some 10x engineers will be speaking. Who’s interested in joining or speaking? Hit me up. 1.5 years ago I was already hosting @aigentsbcn, this time I’ll talk about how the future of an engineer looks with tools like @hob_app
Both the project and the presentation are about the same problem: the new attack surface agents create, and the architectures that contain it. Check out the presentation 👇 ▶️ youtu.be/XevNL4AwrHA
🎤 I also gave a talk called "The Agentic Risk" The attack surface that prompt injection opens up in AI coding agents like Claude Code. How an agent can be tricked into leaking your .env just by fetching a malicious docs page 👀
It's been 2 weeks since @ETHPrague 🇨🇿 and I still need to write about it. The venue, the people and the vibes were amazing! Had the chance to attend as a speaker 🎙️ and a hacker 🧑💻 Huge thanks to the team for making it happen 🙌🧵
GG to our most seasoned hackers who pulled off a fully functional app over a sleepless weekend 🫡☕️ 👇 @ferrabled @andlopvic @0xethanol @0xGianfranco ☝️
🇨🇿 Wrapped up an incredible weekend at @EthPrague! Our team built Orloj , connecting AI agents to smart contracts while abstracting away gas and key management. 🤖⛓️ 🏆 Stoked to have won prizes in the @SpaceComputerIO and @SourcifyEth tracks! 👉 app.orloj.xyz 👈
tomorrow at @ETHPrague 🎤🗣️ “Breaking Rollups: How Sequencer Design Shapes Your L2's Attack Surface” if you're around Obecní dům (Municipal House) 🇨🇿, come say hi 👋
Really looking forward to presenting "The Agentic Risk" at @EthPrague with @OpenZeppelin
Pretty cool to see Croisette, our @ETHGlobal Cannes 🇫🇷 project, still up and running Shoutout to my dream team @Draiakoo @0xAdriaTorralba @0xGianfranco @mentasuave01 and everyone for the amazing event🫡
We did it again! @0xGianfranco @ferrabled @Draiakoo @0xAdriaTorralba 🏆1st prize Best OpenClaw Agent 📅EthGlobal Cannes 2026
Three years ago I called my dad and told him coding had just changed forever. Since then, I've changed my whole coding setup three times.
hob is a workspace for AI coding agents. Only the workspace — not the model, not the agent. You bring those. Because when workspace, agent, and model all ship from one company, your tools stop working for you. Your code becomes their training data. Models change. Agents
