Last Friday, @VitalikButerin visited the Urbe Hub 🐺 We welcomed researchers from the Ethereum Foundation and a few external visitors for a full day of coworking focused on Ethereum’s post-quantum roadmap. Shoutout to @asanso as well for helping coordinate the day. We opened the Urbe Hub a little over a year ago with a simple goal: to create a place where builders, researchers, and people passing through could sit together, work together, and exchange ideas. Friday felt like a reminder of why we opened these doors in the first place. People helping shape Ethereum spent the day here doing exactly what this space was made for. If you’re building frontier tech, whether in Web3, AI, or beyond, if you live in Rome, or if you’re just passing through, the Urbe Hub is here. Come find us!

Introducing Watchy 🔭 A trustless audit service for AI agents, powered by ERC-8004 running in @eigencloud TEE. Your agent pay 0.50 USDC and gets a verifiable audit that builds on their onchain reputation. Here's how it works 👇

Two incredible days in Rome, celebrating @urbeEth Hub becoming an official Ethereum Community Hub 🐺 On the first day, the local community came together to reflect on a year of building at the hub, with @limone_eth, @matteoikari, and @gallo_eth sharing the journey so far and what’s ahead. Builders joined from across Italy to connect and celebrate! The second day featured a Web3 Forum on ERC-8004 with members of the Ethereum Foundation dAI team, @DavideCrapis, @VittoStack, and @Marcello_AI, sparking thoughtful discussion on the intersection of Ethereum and AI. We’re proud to support the Rome Ethereum Community Hub as they continue creating spaces for builders to connect and grow!

1/ The next Ethereum Community Hub is launching in Rome! Hosted by @urbeEth, an active builder community, it's a vibrant space for web3 builders and students to learn and build in the heart of the region. Join the launch meetup and the dAI team event on the future of AI! 🧵

ERC-8004 is supposed to help us trust AI agents. But can it withstand hacks and manipulation? In this @Unchained_pod episode, @DavideCrapis joins me to unpack: 🤖 What the ERC-8004 standard is 🤔 How ERC-8004 works 📝 The project's roadmap 💫 Tips for AI agent builders/businesses Timestamps: 🚀 0:33 Introduction 🤔 2:23 What is ERC-8004? 💡 14:45 How the standard resolves chokepoints in AI agent discovery 🧏‍♂️ 20:07 How ERC-8004's reputation registry works 🤖 34:57 How ERC-8004 identifies agents 💡 41:39 How ERC-8004 enables users to vet AI agents beyond reviews 👀 44:26 Can ERC-8004 be gamed with multiple bots? 📝 56:14 Which chains are compatible with ERC-8004? 🛣 57:50 What's next for the ERC-8004 project? 💥 59:55 How agents will manage reputations across different blockchains 🤔 1:02:28 How can x402 be used with ERC-8004? 💫 1:04:54 What Davide says has been the most interesting part of building ERC-8004 💡 1:10:03 Davide shares tips for agent builders with business ideas

LIVE NOW - AI on Ethereum: 8004, x402 and the Botconomy AI agents are moving onchain, so Ethereum needs new rails for identity, reputation, and payments. We had @DavideCrapis and @austingriffith to break down: ERC-8004: “AI passports” for agents (identity reputation validation) Why reputation verification matters when bots become the main onchain users x402: pay-per-call payments for agent-to-agent services What “agent commerce” looks like when bots can discover → trust → pay The Clawdbot/OpenClaw moment, and why the next UX is talking to your wallet Watch now. -------------- TIMESTAMPS 0:00 “AI is the new UI,” and you’ll be talking to your wallet 4:09 Is there an arms race for AI activity across chains? 7:32 The Clawdbot/OpenClaw moment: agents get OS-level power 13:18 Why crypto is native to agents 19:41 Austin’s setup: Claude bot, heartbeat loops, and real autonomy 22:28 The token incident: how a bot “got a treasury” 28:46 Prompt injection meets wallets 38:20 ERC-8004 explained: identity, reputation, validation 40:35 x402 8004: discovery payment rails for agent commerce 48:38 8004 “scans” and early adoption reality 1:05:32 What agents could build when they can hire other agents 1:12:38 Tooling for the new builder era: Speedrun → Wingman 1:25:23 “Worst time to be a junior dev…” 1:28:15 Predictions: clean English becomes the sign of AI

What if AI agents could be open, composable, and verifiable onchain? On Feb 16, together with @ETHGlobal, we’re hosting a Web3 Forum at Urbe Hub focused on ERC-8004, the proposed Ethereum standard for decentralized AI agents. We’ll welcome the Ethereum Foundation AI team onsite in Rome, with introductions by @DavideCrapis, @VittoStack, and @Marcello_AI, followed by a roundtable moderated by @matteoikari. 🕕 6:00 PM – 9:00 PM 🍷 Aperitif to close Register in the first comment👇
