Agent Mania Evolved From Meme Experiments To Real Infra

  • The AI agent phase shifted from meme experiments to infrastructure as builders standardized protocols and kept improving agents.
  • Davide says ERC-8004 is unifying identity and reputation, turning isolated bots into composable services on a shared railway.

ERC8004 And X402 Are The Railway For Agent Commerce

  • ERC-8004 plus X402 create the three rails for agent commerce: payments, discovery, and trust.
  • X402 handles machine-to-machine micropayments while ERC-8004 standardizes identity and registries so agents can be discovered and evaluated.
