ERC-8004 Explained: Building Trustless AI Agents on Ethereum

ERC-8004 is an Ethereum standard that gives AI agents verifiable on-chain identity, reputation tracking, and cryptographic validation through three lightweight registries. Over 100,000 agents registered across 19 chains within weeks of its January 2026 mainnet launch (ainvest, 2026). It's the trust layer the agent economy was missing.
