ERC-8004 is gaining traction as a new trust layer in blockchain, following the surge in AI Agent payments facilitated by x402. This protocol offers identity, reputation, and verification registration mechanisms for on-chain AI, enhancing the security and reliability of transactions between agents. Unlike x402, which focuses on payments, ERC-8004 aims to establish a decentralized business and credit system. The two protocols complement each other, potentially creating a trustworthy automated transaction ecosystem. Projects like Taiko, EigenLayer, and Virtuals have already integrated ERC-8004, with Devconnect poised to be a significant catalyst.
