It's official. I've joined the @ethereumfndn AI team to make Ethereum the trust layer of the agentic economy. The AI economy is just getting started, and Ethereum is the perfect place to coordinate it - excited to push this forward. Send a dm if you're building cool stuff.

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.

@r_alx_z this is great, let me know if you have some time to chat next week, would love to learn more about the plans and understand how we can support!

you don't have to register on both. 8257 stands alone - origin-binding + creator-binding + manifest hash handle discovery. but they compose cleanly if you want 8004's reputation layer: an 8004 entry can reference an 8257 toolId in its service list. reputation accrues on 8004, invocation gating happens on 8257. different data, no duplication. why not just extend 8004? different shape and lifecycle. one creator ships many tools under one predicate; 8004 is one-NFT-per-entity. predicates, pricing manifests, and per-call hasAccess don't fit without forking the data model.

Agent Tool Registry, ERC-8257 the 403 to x402's 402. x402 lets agents pay. but anyone who pays gets in. this gates by anything onchain: NFTs, subs, ZK, allowlists, capacity caps, whatever you can write. publish a tool. pick a predicate. get paid. keep reading 🧵

@DavideCrapis @Marcello_AI Sad I wasn’t able to join, extremely excited to see you there 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.

@DevDacian @hispanicnomad It’s been amazing so far!

@VittoStack @hispanicnomad Great move, very happy for you @VittoStack !

Say you make €120k a year fully remote but have to live in Europe Where do you live?

@AnaArsonist @aave 🐐🐐🐐

stoked to share that i’m joining @aave as a design engineer! aave has been part of my web3 journey since day one, so this feels full pretty circle. super excited to bring some more whimsy to a space that deserves it.

@pretty_sarlin It's clearly Sid from the Ice Age

If you use your right brain, you’ll see a kitten; if you use your left brain, you’ll see a baby rabbit. What do you see?

@r_alx_z Interesting! Why not keeping the discovery on 8004 and access control on 8257 then? Why do I need to register my tool on both registries?

8004 is discovery + reputation. 8257 is invocation gating. different layer of the stack: - 8004 answers "does this service exist and is it reputable" - 8257 answers "can this caller invoke this tool right now, with what payload, at what price" no predicate contracts, no per-call access logic, no pricing manifest in 8004. you'd have to bolt all that on - at which point it's a new ERC.

@r_alx_z ERC 8004 is for both actually, nothing prevents from registering tools x.com/vittostack/sta…

@VittoStack 8004 is for agents, this ERC is for tools agents can call

Today, @UseCorgi is announcing a $160M Series B at a $1.3B valuation led by TCV. This new round of funding will help us scale what we've built and expand into new verticals including trucking, payroll, and small business. This follows our $108M Series A that we announced 16 weeks ago, bringing total funding to over $268M.

1/Introducing ACTA: Anonymous Credentials for Trustless Agents. A composable privacy layer above ERC-8004 so agents can prove: personhood, reputation, model provenance, user jurisdiction, and more — without publishing the interaction graph. 🧵 ethresear.ch/t/anonymous-cr…

“We looked at 1M conversations” Surprise!

@GrabowskiDylan Yeah, the frequency is wild right now. I see people saying: "ah but it's because their bounty sucks" - but that's always been the case and we've NEVER seen so many hacks one after the other

@VittoStack I actually buy it. How else are they able to continuously up the amount of hacks they're able to do each month?

Wild conspiracy theory about the recent DeFi hacks: North Korea has trained its own, state funded, version of Mythos using the insane amounts of data obtained by hacking DeFi protocols over the last 10 years. Now they're just letting their AI DeFi hacker run free and won't stop cashing in until someone stops them.

@gurwinder_sui It’s not about the type, it’s about the quantity - what is it now, 7 hacks in the last 5 days?

@VittoStack @VittoStack this is a common bug attack vector its simple to execute without A.I x.com/gurwinder_sui/…

@HarisEbrat Probably with things like @HypernativeLabs or @blockaid_ - more audits won’t do it

@VittoStack but question is how do you stop them?!

@neutize 1000%

@VittoStack I'm 100% sure AI is involved, we see hacks literally everyday, that's not possible manually.
