According to AI News on X, ERC-8004 is now live on more than 10 mainnets, introducing an on-chain standard to build and manage AI agent identity, reputation, and validation, with early builders showcasing implementations at the 8004 Launch Day event (source: AI News on X, luma.com event link). As reported by AI News, support across ecosystems including Ethereum, Avalanche, and BNB Chain signals multi-chain readiness that can enable verifiable AI agent credentials, reduce sybil risks, and unlock marketplace primitives for pay-per-task agents and auditing rails. According to AI News, the standard creates a shared schema for identity attestations and reputation scoring on-chain, offering enterprises and developers a path to trusted AI agent orchestration, compliance-friendly logging, and interoperable agent marketplaces.
