AI Lead at Ethereum Foundation · dAI Team
Joined December 2011
We’re starting a new AI Team at the Ethereum Foundation (the dAI Team). Our mission: make Ethereum the preferred settlement and coordination layer for AIs and the machine economy. The team will focus on two main areas: - AI Economy on Ethereum = giving AI agents and robots ways

online papers and publications should use x402 and let people pay for a single article who's working on this?

glad to see the new Ethereum blob data pricing mechanism going live in the latest upgrade! the best ideas always win. here is my very short story behind this change that shows resilience in open-source and Ethereum: one of my early contributions to ethresearch was showing how
Tonight, Ethereum updates its blob pricing mechanism with a blob reserve price. In this post, I share three reasons why EIP-7918 ties the reserve price to the execution price, and the trick that made it all come together on the final submission day. https://t.co/CbNcRgg9WT

farcon is coming to rome 🇮🇹 the @farcaster_xyz community is going to meet soon in one of the most iconic cities in the world, and we’re so hyped to bring the purple energy to the eternal city 🗓️ may 4–5, 2026 - clear your calendar for two days, creators, builders, founders,

So C3PO and R2D2 would probably pay each other using x402 Super cool experiment by @VittoStack
x402 made payments native to HTTP. I made USDC payments native to sound waves ✨ Not as a gimmick. As a proof. 1/ The setup: @CoinbaseDev's x402 protocol embeds payments into HTTP. It's brilliant. But I started wondering, if we can pay over HTTP, what else can we use to

"Of course agents need programmable money. Blockchains are the perfect technology for agents. But how do we solve and aggregate reputation?" Our starting panel on ERC 8004 is a must watch to understand how the agentic space is developing.

Wanted to thank some EFers who contributed in a meaningful way • @skylar_eth the goat, also my friend and therapist, who helped to maintain his heritage :D • @0xstark for coming up with the EWF concept, inspired by @jillrgunter (I believe https://t.co/gFcZZLXt0O) • all teams
ETHCC has been great but hasn’t left me wanting to go to another conference. Instead, I want to go to an Expo: a World’s Fair of crypto. No more panels. No more talks. Let’s have exhibits! Show me the future. Show me what you’ve built. Let me touch it and feel it and use it!

Nethan & team have done an incredible job. Innovation on @EFDevcon format + high-quality execution, pulling EFers and thousands of ecosystem volunteers to help! Looking forward to collab closely on India 2026! Perfect place for decentralized AI.

We said at Trustless Agent Day @EFDevcon that x402 needs trustless discovery. Today the first 8004 facilitator is live on testnet and fully open-source, the earliest example of 8004 plugged directly into the x402 flow. Up next: the official 8004 extension + trustless discovery.
Today we are launching OpenMid — the first 8004-native facilitator for x402, built to connect identity, reputation, and payments for the agent economy. As unveiled at Trustless Agent Day @EFDevcon by @davidecrapis and @codywang999. Devconnect session replay below 👇

What is the relationship between 8004 & x402, and why do we need them? This is a question I've been asked multiple times during DevConnect. Currently, we're seeing a rise in agent frameworks designed for specific use cases, often developed in various programming languages. This

Building the initial step for decentralized and public discovery for millions of x402 agents in the future. Check out the /register endpoint and the open sourced repo! Hoping more agents will be registered on 8004 via this facilitator

Ethereum + AI agents are about to define 2026. ERC-8004 is the missing trust layer. This is how the machine economy actually starts.

The first 8004 facilitator going live on testnet as fully open-source is a big deal. It proves 8004 agents can run independently inside the x402 flow, not just in theory but in practice. This essentially unlocks permissionless, composable agent coordination and brings

Built agent8004 for the @WalrusProtocol Haulout hackathon. It is an implementation of the erc8004 standard on Sui, with smart contracts written in Move why this matters? AI agents shouldn't be chain-specific, they should be global. 8004 saw interest from Near and Solana

Cool to see erc8004 being implemented on many blockchains 8004 contracts are already live on testnet on EVM networks now it’s proliferating beyond EVM. trustless agents incoming!

The Anthropic announcement nails this aspect. Agentic tool use needs to dynamic. But, paying for tools dynamically selected by the agent won't scale if you need to pull out your credit card each time. x402 solves this. 6 months ago I wrote an example of an agent dynamically
