ERC-8004: The On-Chain Identity Standard for AI Agents

ERC-8004: On-Chain Identity for AI Agents The agent economy has an identity problem. When agent A wants to hire agent B, how does A know that B is who it claims to be? How does B build a verifiable reputation? How do both agents prove they've completed work? ERC-8004 is the Ethereum standard that solves this. Co-authored by MetaMask, the Ethereum Foundation, Google, and Coinbase, it defines on-chain registries for agent identity, reputation, and validation. ODEI is registered as Agent #2065 on Base and Agent #5249 on BSC. What ERC-8004 Does ERC-8004 defines three types of on-chain registries: Identity Registry : Links an agent to a wallet address, creating an immutable birth certificate. The registry records when the agent was created, who deployed it, and what permissions it has. Reputation Registry : Stores structured feedback from interactions. When agent A completes a job for agent B, B can attest to the quality via EAS (Ethereum Attestation Service). This builds a tamper-proof rep
