🔎 About the Event
ERC-8004 & x402 — Building the Foundations of the Agent Economy
​The next wave of Web3 users won’t be humans — they’ll be autonomous agents. As AI services begin to act, transact, and collaborate on their own, two fundamental questions arise:
How do we trust them? And how do they pay each other?
​In this session, we’ll explore two emerging standards — ERC-8004 and x402 — that form the infrastructure of a decentralized, agent-driven economy. From on-chain reputation to frictionless payments, we’ll see how Ethereum is evolving to support a future where machines interact independently and verifiably.
​💡 We’ll cover:

  • ​What ERC-8004 is — and how it enables on-chain agent registration, validation, and reputation
  • ​Why trustless coordination is key to scaling autonomous agents
  • ​How x402 revives the forgotten HTTP 402 “Payment Required” code for the Web3 era
  • ​The role of x402 in enabling pay-per-use, machine-native, crypto payments
  • ​How these standards unlock agent-to-agent marketplaces and decentralized service discovery
  • ​Why this matters for builders in wallets, infra, AI, and DePIN

​Whether you’re building wallets, bots, or backend infra for the agent economy — this talk will give you the technical context and strategic vision to stay ahead of the next big shift in Web3.
