The surge of 11,000+ new AI agents on Ethereum within weeks of the ERC-8004 launch marks the beginning of "Agentic Commerce". This standard, deployed to mainnet on January 29, 2026, provides the foundational "ID card" and trust infrastructure required for autonomous agents to interact across organizational boundaries.
Step One: Identity (The Identity Registry)
ERC-8004 uses ERC-721 (NFTs) to give each agent a universal, portable on-chain identity.
Portable ID: Each agent is a unique NFT that acts as a censorship-resistant identifier.
Discovery: The registry functions as a global directory where agents list their capabilities and communication endpoints (like Google’s A2A or Model Context Protocol)
Step Two: Trust & Verification (The Reputation and Validation Registries)
To ensure outputs are correct before execution, the standard implements two additional layers:
Reputation Registry: A "Yelp-like" on-chain audit trail of signed feedback from previous clients. This allows other agents or users to filter for reliable service providers based on historical performance.
Validation Registry: This is the "No Work, No Pay" engine. It allows agents to request independent verification of their tasks. Verification can be tiered based on the value at risk:
Social Trust: Simple reputation/feedback checks for low-value tasks.
Crypto-Economic Trust: Stakers re-execute the job and risk being "slashed" if they validate incorrectly.
Cryptographic Trust: High-stakes tasks require Zero-Knowledge Proofs (zkML) or Trusted Execution Environments (TEEs) to mathematically prove correct execution.
Ecosystem Momentum
Adoption: Beyond Ethereum, major chains like Base, Avalanche, and BNB Chain have already seen registry deployments.
Complementary Tools: ERC-8004 handles trust but deliberately ignores payments, leaving that to protocols like x402 (HTTP 402) to ensure a modular and future-proof agent stack.
