AI is the new UI

the trustless agent stack is here. use it. improve it. or be left behind.

The Trustless Agent Stack. ERC-8004 and x402 lay the foundation for an AI agent economy that is projected to reach $30T by 2030. Combined with verifiable and deterministic AI execution, this tech stack enables autonomous AI economies where: → Agents prove their execution with cryptographic attestations → Agents build reputation and advertise capabilities on-chain → Agents discover, evaluate, and transact with zero intermediaries New end-to-end guide: How to build trustless, autonomous, and unruggable agents. docs.eigencloud.xyz/products…

Go build with EigenAI: world's first deterministic LLM API. Same input, same output, every time.

i have been trying to wrap my head around how A2A, AP2 (both from @Google), and x402 (from @coinbase) actually fit together in the communication stack of agentic commerce. thought it will be useful to share my notes for others trying to piece this together. ------------------------- in simple terms, A2A = the grammar for inter-agent communication. AP2 = an extension of that grammar for auditability, which involves attestation to cart and payment details. x402 = an extension to that grammar for actual payments. think of A2A as how agents talk, and AP2/x402 as how they agree and pay. also, A2A is designed to be extensible, allowing devs to add new extensions. ------------------------- to ground this, let's take a fun example. imagine @Bankless recruiting an AI debate judge for justin vs. toly debate 2.0. > bankless’s agent discovers the best judge by analyzing the reputation of judges listed in an ERC-8004 registry. > once it picks one, it sends a standardized A2A "message" describing debate requirements. > the judge agent replies with an AP2 "cart mandate" ( basically the price quote + terms), wrapped inside an A2A "task" object, which also includes x402 payment details. > bankless reviews and attests to this cart mandate and payment mandate (essentially payment info). > the attested payment mandate is shared with x402 facilitator, which verifies and executes the payment. > finally, the judge agent sends a receipt + link to the debate stream, stored on EigenDA who then responds back with winner of debate later. imagine bankless running dozens of micro- and macro-debates judged by AI speech models, that would be something. the use of a “task” object (as per A2A) is key when two agents interact multi-turn over the same context. ------------------------- this was a fascinating exercise in mapping the communication stack of agentic commerce, hope it helps others connect the dots too.

one year ago today i vibe coded the agentkit prototype today, x402 passed 1 million transactions and $1 million in volume -- with enterprises and startups both onboard where will onchain agentic commerce be this time next year?

Heads up: @nima_vaziri, our General Manager of AI, is taking the stage today at the @dAGIhouse in SF 🌁 If you’re attending, don’t miss his session on how verifying AI and agents is reshaping markets, and what it means for the future of decentralized intelligence.

new-day-new-hack so last time i dropped nocturne, a verifiable AI trading agent on hyperliquid and many people said "just run it for me". this time, we go one level higher. introducing Sigma Arena verifiable copy trading vaults, anyone can deposit into it, and it mirrors positions & trades by top @the_nof1 agents (DeepSeek, Qwen); 100% open source, verifiable. i'm starting with $10K deposit limit on each vault, will lift if as the vault gets more traction and good performance. execution verified by eigencloud SigmaArena [dot] com (deposit at your own risk, NFA) code in replies + info in the video

This time it really hits different when we say onchain is the new online. AI, finance, consumer / prediction markets are just starting to take off onchain. With more than 100x growth in transactions per second in the last 5 years, this is the decade of crypto.

Our latest State of Crypto report is here. The main theme for the year is the maturation of the crypto industry: • Traditional financial institutions and fintechs launched crypto products • DeFi and stablecoins went mainstream • Blockchains got faster and cheaper • The regulatory shift in the U.S. revived builder confidence Find the full 2025 State of Crypto report here: a16zcrypto.com/posts/article… See below for a few highlights.

The era of deterministic AI has arrived 🌩️ Join @0xAron and @xpranavprakash from @fere_ai alongside our very own @nima_vaziri LIVE as they unpack how FereAI uses EigenAI’s verifiable inference to power reproducible, audit-ready trading agents, turning AI from inspiration into infrastructure. Going live tomorrow! ⏰ Thursday, Oct 23, 7am PT / 2pm UTC RSVP link in 🧵

LMArena but make model / agent ranking economical and verifiable

ethereum everywhere

Verifiable AI + Proof of Human = fair competition. AI shouldn't be able to game the games, even if it's a player.

The incoming era of the web is scaling the capabilities of AI while scaling the onchain truth registry that becomes the trusted economic network of AI.

In <6 hours at the Berkeley 10² Hackathon yesterday, @vardhans03, @djbkwon, and I built Polyhedg to turn prediction markets into corporate hedging infra. Trump announces tariffs. Monsoons hit supply chains. Geopolitical tensions escalate. In all these scenarios, CFOs watch helplessly as billions evaporate. With Polyhedg, we transform these unpredictable losses into fixed, budgetable costs. Our verifiable agent (deployed on Eigenlayer TEE) performs Bayesian event correlation across Polymarket's prediction markets, creates weighted probability pools via event aggregation when exact matches don't exist, and calculates the optimal hedging strategies. Welcome, certainty-as-a-service.

Very excited to announce the new home for everything x402! We call it x402scan
