I’ve joined the 𝗱𝗔𝗜 𝘁𝗲𝗮𝗺 at the @ethereumfndn ♦︎ Our team, led by @DavideCrapis, is building the trust and coordination layers that will let AI agents and humans collaborate freely on @ethereum, an open economy for verifiable intelligence. Our work spans areas like the ERC-8004 agent standard, defensive AI, multi-agent systems, verifiable decentralized inference, and AI security. It’s time to make #AI on Ethereum real and open to everyone. 🤖

@VittoStack @ethereumfndn dAI shipping again 🔥

What if you could have a local wallet that's: - AI native - Privacy first - Secure - Fully local - Open source Coming soon, from your beloved @ethereumfndn dAI team.

📚 𝗣𝗮𝗽𝗲𝗿 𝘄𝗼𝗿𝘁𝗵 𝗿𝗲𝗮𝗱𝗶𝗻𝗴 "𝗦𝗲𝗹𝗳-𝗶𝗺𝗽𝗿𝗼𝘃𝗶𝗻𝗴 𝗮𝗴𝗲𝗻𝘁𝘀 𝗱𝗼 𝗻𝗼𝘁 𝗵𝗮𝘃𝗲 𝘁𝗼 𝗺𝗲𝗮𝗻 𝗳𝗶𝗻𝗲-𝘁𝘂𝗻𝗶𝗻𝗴" I recently read 𝑨𝒈𝒆𝒏𝒕𝒊𝒄 𝑪𝒐𝒏𝒕𝒆𝒙𝒕 𝑬𝒏𝒈𝒊𝒏𝒆𝒆𝒓𝒊𝒏𝒈 (ACE) -> instead of touching the weights, the model improves by rewriting its own 𝗰𝗼𝗻𝘁𝗲𝘅𝘁, treated as a living playbook of strategies. 📌 𝗧𝗵𝗲 𝗶𝗱𝗲𝗮: the context is a set of itemised bullets, each a reusable play with a helpful / harmful counter. 📌 𝗧𝗵𝗲 𝗽𝗿𝗼𝗯𝗹𝗲𝗺 𝗶𝘁 𝗳𝗶𝘅𝗲𝘀: most methods rewrite the whole context every step, and the model slowly compresses it into a short summary. But this makes the context collapse (quality degradation). 📌 𝗛𝗼𝘄 𝗶𝘁 𝘄𝗼𝗿𝗸𝘀: a Generator, Reflector, Curator loop writes small deltas. It appends new plays, bumps the counter on the ones that worked, and dedups near-copies. It never does a full rewrite. +𝟭𝟬.𝟲% on agent tasks, +𝟴.𝟲% on financial reasoning, and 𝟴𝟲.𝟵% lower adaptation latency. #AI #LLM #Agents

@matteoikari @EFetheverywhere @Snapcrackle 💔

I'm really proud to have contributed (even if in a small way) to EF and Ethereum, which will always remain a technological miracle to me. Thank you to my team in @EFetheverywhere for this incredible year, and to @Snapcrackle for giving me this opportunity one year ago 🙏

Announcing Ethlabs: a non-profit R&D lab for Ethereum and ETH Our mission is to make Ethereum the settlement layer of the global economy. The internet became global because shared protocols created a common language between networks. Private systems remained useful, but bounded. Finance is approaching a similar moment. As value, assets, and markets become digital, the world needs shared settlement infrastructure. Ethereum is uniquely positioned to become that shared base layer, the neutral foundation on which users, institutions, and agents can transact without intermediation. What we believe: • We believe credible neutrality matters. Ten years of uptime and the lowest counterparty risk. Ground that cannot be pulled away by any one country, institution, company, or person. • We believe ETH matters. The most valuable, programmable store of value. A decade of broad distribution, deep liquidity in onchain markets, and maximally trustless asset on Ethereum. • We believe DeFi matters. Markets, liquidity, credit, exchange, and coordination, open to anyone. • We believe adoption matters. Principles do not change the world until people benefit from them. We sit between two worlds: real usage from the builders at the frontier, and the protocol that has to support it. We work with users, applications, wallets, L2s, infrastructure teams, institutions, ETH holders, core devs and researchers, then turn what they actually need into protocol work, shared standards, infrastructure, and shipped products. Ethlabs is independent but Ethereum is a shared project. We are one node in a much larger network of stewards. This is the multi-node future. We have spent the better part of the past decade contributing to Ethereum core research and development. We are opinionated and transparent. We move with urgency, learn in public, and course-correct when we’re wrong. We are building a lean, talent-dense team for people who want to do the most important work of their careers: join@ethlabs.org

On Thursday, I’ll be in Bologna at @WMFWeMakeFuture! I’m excited to join the panel with @matteoikari and @Frankc_eth discussing: 𝐎𝐩𝐞𝐧 𝐒𝐨𝐮𝐫𝐜𝐞 𝐯𝐬 𝐂𝐥𝐨𝐬𝐞𝐝 𝐒𝐨𝐮𝐫𝐜𝐞 𝐦𝐨𝐝𝐞𝐥𝐬 𝐚𝐧𝐝 @ethereum 𝐑𝐨𝐥𝐞 𝐢𝐧 𝐭𝐡𝐞 𝐍𝐞𝐱𝐭 𝐆𝐞𝐧𝐞𝐫𝐚𝐭𝐢𝐨𝐧 𝐨𝐟 𝐀𝐫𝐭𝐢𝐟𝐢𝐜𝐢𝐚𝐥 𝐈𝐧𝐭𝐞𝐥𝐥𝐢𝐠𝐞𝐧𝐜𝐞.

今年过的最有意义的一次生日🎂 美好的5月，幸运地和以太坊基金会dAI Team的 @Marcello_AI 请教学习，给他看了我们现在在做的产品，他也很赞同未来A2A economy和链上Agent市场一定是大方向，最好的web3应用和基础设施将服务于AI和智能体经济，让曾经仅靠web2无法实现的事情都能成为可能。 去年在阿根廷见到ERC-8004创始人，到今年开始做AI Agent Marketplace，超级精彩的一年，感谢@ethereumhkhub 邀请，能给创业者提供这么好的场地和交流机会，新的一岁坚定的持有ETH，继续Build something meaningful to the world. #ETH

@ethereumfndn dAI Team @Marcello_AI: Explored the rise of the "Agent Economy," addressing the coordination complexities of multi-agent systems and detailing adversarial testing to harden Agent defense strategies.

We wrapped up a high-level, invitation-only meetup at the #ETHHKHub, hosting the EF dAI Team alongside top builders and researchers. The focal point? Solving security, economics, and infrastructure challenges for AI Agents in Web3. Here are the key insights from the keynotes: 👇

Just spoke at @themu_xyz about the Agentic Economy and #AI Safety. My take is that Agentic Economy will run on #Web3 infra, Ethereum is an ideal environment, agents can transact, coordinate, and own assets natively and programmatically. But multi-agent systems introduce 𝐧𝐞𝐰 𝐭𝐡𝐫𝐞𝐚𝐭𝐬: collusion, market manipulation, expropriation, broken governance, and blurred accountability. We need to take a proactive approach and start working on these challenges now. 📝 Paper: arxiv.org/abs/2603.20925

Great conversations with the dAI team & excited for what’s next! Welcome to Shanghai!

dAI <> @MiniMax_AI one of the leading teams in open source AI hosted us in Shanghai we discussed the infra we’re building for the open agent economy, multiagent AI, security grateful to meet head of eng @SkylerMiao7 - he shared impressive work on agent orchestration & feedback

@DavideCrapis @MiniMax_AI @SkylerMiao7 It was great visiting the @MiniMax_AI offices and meet their team!

The Ethereum Foundation dAI team supports Urbe Hub, Italy's official Ethereum Community Hub. Urbe Hub is the meeting point between AI and Web3: a physical space in Rome where builders, researchers, and the curious come together to build on the convergence between these two frontiers. With the support of the Ethereum Foundation dAI team, we'll keep building this here, in our city.

We are glad to host Ethereum Foundation (@ethereumfndn) dAI team: Head of AI Davide (@DavideCrapis) and Research Engineer Marcello (@Marcello_AI) to meet with community builders and discuss the future prospects of decentralized AI on Ethereum. Feel free to reach out for introductions. Learn more about the dAI team: ai.ethereum.foundation/team

dAI Team in China this week! We’re meeting so many people that are excited about Open Source AI and the properties that Ethereum can deliver. Scaling multi-agent systems, making AI more private, secure, and servicing the human users.
